Only for ovens with steam generators, if the water quality, we suggest installing the following, if necessais completely devoid of mineral salts, we recomry, either individually or in succession: mend the use of mineralizing water treatment filters.

6.4 WATER TREATMENT SYSTEMS (NOT RECOMMENDED) Below we show the water treatment systems not recommended for use with the ovens: • SODIUM ION EXCHANGERS

With these systems the Calcium molecule (Ca, which determines the hardness of the water), is replaced by the sodium molecule (Na). If the chlorine concentrations in the water are greater than 50 mg/l, the sodium binds to the chlorine dissolved in the water, forming NaCl (= table salt). This increase in salt causes two serious problems: • a delay in bringing water to the boiling point with a

subsequent increase in consumption.

• boiler corrosion that often leads to it breaking

down. • SILICATE DISPENSERS

These systems are highly inadvisable since the mixture of silicates (non-conductors) disturbs the correct detection of the water level.

TECHNICAL MANUAL 03/2014

6.5 SETTING WATER HARDNESS The electronic versions make it possible to program the frequency with which the boiler needs to be descaled by entering the data of the supply water. In short, greater hardness means more frequent descaling that will be shown by the "CALCARE"/"CAL" alarm that appears at start-up. On the initial display for card Naboo, the "Descale boiler within 15 days" warning will appear: if descaling has not been carried out by the end of the 15 days, the boiler will be disabled. For this purpose, it is essential that you: • Establish the type of installation in question (case 1

or case 2) • Check/analyse the water hardness connected to soft water inlet (for further details see CHAP. 6.2) expressed in French degrees °fH with appropriate hardness tester (case 1) • Find out the technical data of the water-softener if it is dedicated exclusively to treating the water for the oven (case 2). Case 1: appliance connected to a centralized softened water supply system ensuring constant treatment; there is no water-softener dedicated exclusively to the oven.

Set parameter 143 “Mains water hardness” °fH according to the hardness measurement taken. The standard value assigned to the parameter (20 °fH) is significantly higher than the maximum set (6 °fH) in order to set more frequent descaling and thus protect the steam generator against the build-up of limescale. • Set parameter 144 “water-softener chapacity” to “0”(zero); the standard value assigned to the parameter is 50 m3. • Leave parameter n. 142 "time consumption" at "15".

Case 2: Appliance equipped with a water-softener dedicated exclusively to the oven.

In this case, it is necessary to set the following parameters: Parameter 142: hourly consumption of softened water by the oven (see table 3 “General water data” - section 16). Example: the model the electric model 6 pans GN1/1 has a maximum softened water consumption of 10 l/hr. Parameter 144: chapacity of the water-softener to ensure constant treatment of water at 6 °fH, based on the watersoftener manufacturer's data tables, given the “degree of hardness (°fH) of the water upstream of the water-softener”. Parameter 143: Leave at 20 °fH. In brief, the electronic pc board defines the descaling interval on the basis of “water-softener chapacity” and “hourly consumption of softened water”. To check the time remaining before the appearance of the message “DESCALE” on T version or “DESCALE” on H/P version indicating the need to descale the boiler, see respectively section “Boiler descaling interval check” (CHAP. 14.9) and (CHAP. 14.22) of this manual.

ATTENTION If you don't intend to customize the de-scaling interval, do not change the standard parameter values. The PCB automatically sets a medium security de-scaling interval.

6.6 OVEN DRAIN CONNECTION Water draining is done in free fall with a DN 50 NT (non flexible) pipe that is heat resistant, has a maximum length of 2 m and is installed with a constant inclination of no less than 4°. Average temperature of drain water: 65°C.

608

Fig. 609 show the direct connection with the trap without the need for the interposition of a bell since the system exhaust manifold is equipped with an interior air gap (Fig. 609). If there is a floor drain without a trap, a free output distance of 2 cm is necessary (Fig. 610). The trap is a hydraulic element inserted in a conduit created using a "U" shaped pipe. Its purpose is to create an obstacle to the passage of foul odours due to the presence of residual water in the loop which obstructs the passage of the odour.

609

m m 0 0 3

The use of a bell that ensures a minimum air gap of 25mm between the curve of the plastic drain on the appliance and the drain piping (Fig. 611),makes it easier to move the equipment and insure physical separation from the local drain system.

6.7 GAS CONNECTION PROCEDURES GAS CONNECTION: 612 The section of the gas supply pipe must be chosen according to the type of gas and the consumption of the appliance to be connected. The system must be designed and installed in accordance with current regulations.The gas attachment on the oven is R 1/2” or R 3/4”. 613

ATTENTION In no case is the reduction of the gas supply input section admitted, penalty appliance malfunctioning!

GAS INLET

A fast acting shutoff valve must be installed on the gas inlet line to the oven.It must be certified according to the current laws in the country where it is installed. The connection to the gas main can be permanent or detachable; if flexible metal tube is used, this should be made of a stainless and corrosion resistant material (rubber hose is not recommended). If when making the connection you use any sealing materials, they must be type test approved for this purpose. • White “gas inlet” sticker: supply gas inlet connec-

tion (fig. 613). • Red G20 sticker: indicates that the appliance has

been commissioned for G20 natural gas, nominal pressure 20 mbar (fig. 614). • Yellow sticker (G30/G31GPL): indicates that the

appliance has been commissioned for liquid gas, nominal supply pressure 28-30/37; 50 mbar (fig. 615). LEAK TEST:

All connections between the mains and the appliance must be tested for leakage. The recommended method is to use a proprietary leak detection spray; alternatively, a non-corrosive foamy liquid of any general description can simply be brushed onto the fittings: whichever method is used, no bubbles should appear.

ATTENTION Never under any circumstances test for gas leaks with a naked flame!

ATTENTION Clear the gas supply system of any machining debris before connecting the oven!

7.7 ELECTRICAL CONNECTION The electrical power cable for the oven enters through the cable clamp at the bottom of the technical compartment, and has to be connected to the power supply terminal board. (fig. 710-712)

710

ATTENTION Always in gas versions: it is imperative that the neutral wire of the power cable, which must have zero potential (Volts), corresponds with neutral on the appliance. Otherwise, the ionization flame detection system is unable to detect the presence of the flame and systematically shuts the burner off, this making it unusable.(See chap. 16.3) 711

EQUIPOTENTIAL CONNECTION:

Necessary for the connection of all the devices (electrical and neutral) in the installation, so as to ensure a suitable equipotential connection.

L1 N

ATTENTION The appliance must only be operated when earthed Before connecting the appliance to power, check the following: • the mains voltage must comply with the values indicated on the plate • the earthing system must be efficient • the power cable must be made of rubber, of a quality equal to type H07RN-f and with the appropriate sized wires for the maximum load (see the "Specifications Table" at the end of this manual) • the appliance cable must not be directly exposed to sources of heat. • at the time of installation, an efficient omnipolar interruption device must be mounted upstream of the appliance with at least a 3 mm opening. Automatic magnetothermic switches can be used for this purpose. The omnipolar switch must be in the immediate vicinity of the appliance and easily accessible. The addition of a built-in magnetothermic switch with fuse protection is recommended.

IMPORTANT: the trolley structure forms an integral part of the appliance. (fig. 713) For appliances equipped with the optional "WCS" washing system, insert the trolley before executing the "automatic" washing program. The tilting closure (fig. 714) located on the top part of the door, allows the chamber to be preheated without the trolley only in "convection" mode. In all other modes, steam or mixed, the trolley must be inserted for pre-heating.

714

Whereas, during cooking, the structure must be installed inside the chamber to guarantee gaskets sealing and avoid heat and steam escaping from the lower part of the door.

Level the surface as shown in fig. 717 if it slopes towards the front of the appliance (tolerable +/- 1cm).

If there is a floor drain grill in front of the appliance, it will be necessary to mount two steel guides (fig. 718) that allow the insertion and removal of the trolley in order to avoid dangerous unbalancing due to the unevenness of the floor. No vapours that could create infiltrations in the front of the oven and damage the PCBs and inverters (if present) should come out of the drainage grill. If the drainage grill is used to collect hot water from other appliances or from the oven, the entire grill located in the front must be covered (fig. 719).

ATTENTION The appliance must always be correctly levelled based on the inclination of the pavement and the trolley by adjusting the front and rear adjustable (fig. 720)

903

It is motorized and attached to a 3/4" or 1" ball valve according to the model, made up of a gear motor, a cam mounted on the crankshaft and two limit microswitches. (fig. 903) Electrical connection is as follows: BLACK WIRE neutral, RED WIRE phase for opening (OPEN), BLUE WIRE phase for closing (CLOSE).

c

Pay close attention to the colour of the electrical connection wires: NEVER supply power to both the

open and close phases (red and blue wires) as this will short-circuit the component. Operating sequence:

When power is turned on after a shut-down that lasted more than 5 minutes (time limit observed only in digital versions), if the water in the boiler has a temperature lower than 55° C, the motorized valve V1 receives power to the red wire (opening phase) until it reaches the maximum open position (OPEN) (fig. 905) The water in the boiler flows out, and a steam generator wash cycle is executed for "x" sec., by supplying power to solenoid valve S2. The driven valve V1 then receives power at the blue wire (closing phase) (fig. 905) until it reaches the fully closed position (CLOSE), which corresponds to the opening of the micro switch. As driven valve V1 closes, solenoid valve S2 allows the steam generator to fill with water until the maximum level.

ATTENTION The automatic drainage of the steam generator water is activated only if the water inside has a temperature below 55°C (parameter 61), temperature determined by the temperature probe inside SB boiler managed by the electronic board. In ovens with the "CALOUT" system, the steam generator (boiler) is equipped with an additional "SV" level probe located at the bottom which delivers a warning in the event of incomplete emptying of the boiler; if this situation occurs, the boiler is temporarily out of service until the problem is resolved (see chap. 16.3). The steam generator (boiler) of the TOP ovens version is equipped with an additional level probe “EMPTY” located at the bottom, that warns in case of incomplete emptying of the boiler; if so, the boiler is temporarily placed out of use until the problem is solved (see CHAP. 16.3). The steam mode functioning is guaranteed through the direct flowing of water inside the cooking chamber as for ovens without steam generator. Upon each re-ignition, the operator is informed of the anomaly on the steam generator. For greater details see chap. 16.3.

9.6 MOTOR THERMAL CUT-OUTS “SAPIENS” VERSION A1 e A2 Thermal motor protection, for high and low speed respectively (if present)

917

A1

The cut-outs protect the motor in the event of anomalous power absorption. They must be reset manually, by an authorized member of the technical service staff only, so as to establish the cause of the anomaly. The motor thermal cut-out is equipped with two NC and NO contacts: if the thermal cut-out trips, NC (contacts 95-96) opens, thus cutting off the power to the circuit, and NO (contacts 97-98) closes, to enable the acoustic signal to sound and the corresponding error message to appear on the display, for electronic versions. On versions equipped with two-speed motor, it is necessary to determine which of the two thermal cutouts A1 or A2 has tripped, as they are located in series. Press the BLUE reset button fig. 918 or the BLACK button fig. 917 once you have established the cause of the error. To restore the thermal cut-out button on the versions provided with thermal cut-out fig. 917 type, the front controls panel must be dismantled (see CHAP. 7.6); for models of fig. 918, the right lateral side must be dismantled (see CHAP. 7.5). Do not modify the settings of the adjustable thermal

cut-outs. For further details, refer to the data plate on the motor. As regards the remedy to the possible trouble that may have caused the safety devices to trigger, see also chap. 16 If a motor thermal cut-out trips, use an amp meter to check the actual consumption data of the motor (excluding motor start-up phase) compared with the data shown on the data plate: note that the most unfavorable consumption conditions occur during cooling with the door open; consumption should therefore be checked in these conditions. The initial start-up phase involves exceptional motor consumption for a period of 7 - 8 seconds at the most. In normal operating conditions (nominal supply voltage) the 15 sec. pause between clockwise and anticlockwise rotation allows the motor to slow down sufficiently. NOTE: the A2 thermal protection is only present in

ovens with the reduced speed option

9.12 AUTOCLIMA CONTROL PROBE, “SD” STEAM CONDENSATION SD

926

The “SD” temperature probe is positioned in the safety vent pipe and performs the following 3 functions:

SD

- Steam condensation control on exit from the cooking chamber drain: Activates in all cooking modes including convection (think of chicken, for example, which releases a lot of steam/humidity). It powers the steam condensation solenoid valve S5, which sprays COLD water through the condensation nozzle positioned on the cooking chamber drain pipe (areaaim below chamber). The is tothe prevent an anomalous escape of steam from the drain and to contribute to the correct functioning of the abovementioned steam control system, considering that the functions are directly dependent. When the steam escapes at more than 70°C, steam condensation is activated for a few seconds, until the steam is almost completely condensed; the contact is opened as soon as the temperature drops below 70°C. The steam condensation function is managed by a parameter on the electronic board set by default to 70/75°C. The water that feeds the solenoid valve S5 with steam condensation must be COLD, otherwise the steam cooling can not function. - Steam production control: it is activated in the

steam/combi cooking modes and has the function of momentarily interrupting the steam so can to avoid generating more steam thanproduction, the product absorb. This saves energy, provided that the steam condensation system is switched on otherwise, the oven interior cannot reach a state of complete steam saturation. In the steam and mixed function, when the steam is released from the drain at a temperature higher than the one set, the probe turns off the boiler heating and moves the heating to the cooking chamber. When the temperature goes below the limit, the steam generator heating is restarted. - Autoclima: the function allows checking the climate wanted inside the cooking chamber.Through the "SD" temperature probe, the chamber vent motor is activated, controlling its opening or closing and possible emission, in mixed mode, of humidity to restore the selected degree of humidity.

C6 is a safety contactor. The power contacts supply the circuit powering the heating elements and motor. If one of the appliance's safety devices trips, the coil of the is de-energized and the power circuit is promptly disconnected. • C2 - C3 - C4 - C5:

Contactors whose power contacts supply the heating elements of the oven and boiler for oven versions with steam generator, respectively in the following sequence:

C2

High speed convection ventilation: full power is

obtained with the activation of both contactors C2 and C3. In the electronic versions, 5 degrees before the set temperature, C3 is turned off and the power is reduced to limit the phenomenon of thermal hysteresis, C2 is also de-energized.

C3

1001

Convection, low fan speed: full power is never

activated: only contactor C2 activates, and deenergizes when the set temperature is reached. High and low ventilation speed steam: full power

is obtained by activating both C4 and C5 contactors. In electronic versions, C4 and C5 contactors simultaneously de-excite upon reaching the set. Combi, high and low fan speed: contactors C2

and C4 activate, to heat the oven and boiler simultaneously at low power. Once the oven is saturated with steam, full power in the oven is switched over with consequent activation of C3 and disactivation of C5. The initial situation of oven and boiler heating is restored as soon as the oven is no longer saturated with steam.

11.4 GAS VALVE S3 two-stage gas valve, equipped with two coils V1 pin 1-2 and V2 pin 4-5 and central earth connection pin: coil impedance check: V1 ~2.9 Kohm, V2 ~1.3 Kohm. The two gas sockets IN and OUT, make it possible to check the mains pressure, which must be between the minimum and maximum pressures acceptable indicated in table (IN pressure socket) and the output pressure OUT; the latter is normally adjusted around “0” mbar because as the burner does not have nozzles it does not allow significant auto-pressure on exit to thefurther valve. information regarding P OUT pressure For adjustment and any other adjustments necessary in the case of burner functioning anomalies, see chap. 17.7 To adjust the gas output pressure OUT in order to return the value to “0”, use a 40 Torks wrench to turn the plastic screw of the pressure regulator REG shown in figure 812 (remove the metal protection screw to gain access to the regulator REG). To check the output pressure, light the burner at nominal heat capacity (Max Hz) and measure the pressure with a digital pressure gauge. Tightening the screw (clockwise) increases the output pressure OUT , and slackening the screw (clockwise) reduces the output pressure. See Chap. 17.3 for further details Remember to close the pressure socket screws properly and refit the protection screw located on the pressure regulator REG.

ATTENTION Both of the coils are set for AC 115V, any manual supply tests are performed using AC230 V (pins 1 and 5).

ATTENTION The gas valve is calibrated by the company during testing of the oven. Further adjustments during installation are not necessary.

ATTENTION The valves orders as replacements arenot calibrated. Therefore verification and possible adjustment of the output pressure using an electronic manometer is necessary if they are replaced.

Example: we can verify the operation of the cooking chamber lights by choosing the related button on the touch screen. When the lights come on, the relay is operating correctly. Otherwise, the operation can be verified by connecting a tester to the output on the transformer that powers lights or on the output of the PC board. In this the case, in order to open the control panel, refer to the description in chapter ---- and connect a magnet to the control panel to simulate the door closing.

ATTENTION For safety purposes, some relays are timed so they are disabled a few seconds after the Start. The door must remain closed. Relay activation is indicated by the yellow box.

14.9 "NABOO" BOARD - SERVICE - BURNER MANAGEMENT The “Burners management” section allows to check the: speed, ignition stages, minimum power, maximum power of the cooking chamber burners and boiler (if it exists) settings, eventual speed change and burner activation test in order to check the correctness of adjustments (fig. da 1433 a 1436).

to heat up and hold its temperature for 30 minutes (countdown on display) so the descaling agent can act effectively, after which time the boiler drains off the content (impurity of detergent mixed with water). Check that it flows out freely, if it does not then call in the technical assistance service as the drain could be blocked and the boiler need servicing. This problem is also indicated on displays (see “Selfdiagnosis and fault identification”). Afterwards the boiler is cleaned of the more resistant particles of scale by forcing in normal tap water, then it loads cleaned water. “F15”: This is the automatic cycle that permits opera-

ting the oven with steam for 30 min. so as to thoroughly cleanse the steam generator and the pipes for introducing steam into the oven. The cycle is completed with the phases of: drain boiler, wash boiler by introducing ordinary mains water and filling with cleaned water.

Using the temperature knob, display password 123 and confirm, again by pressing the same knob. On displaying the relay to test, for example “rel nr 1”, pressing START/STOP once activates the corresponding relay and pressing it a second time disactivates it (in this case, relay No. 1). In certain cases, for safety reasons, the relay is disactivated automatically after a few seconds. (Fig. 1473). Example: Display relay n. 5 “steam condensation activation relay”. Press START/STOP; solenoid valve S5 is activated automatically, and you will be able to hear the steam condensation running. Upon pressing of the START/STOP button again, the function stops; in case the sequence is not activated, using a voltmeter check effective closing of relay 5 with230 Volt output of the electronic board (see access to electronic board, CHAP. 20.3). Check that there is voltage to the coil of solenoid valve S5, set the multimeter to Ohms and check that the coil is undamaged, and lastly check that the water shut-off tap is open. This program is extremely useful for finding a single fault without having to run an actual cooking cycle involving the use of various functions, and enables you to devote all the time necessary to a precise diagnosis of the fault. In case of having to check functioning of the washing system, connectintroduction the relativeplastic accessories (washing arm, detergent hose, detergent container), to avoid damaging the washing cycle (pump-pipingseals).

the main switch (1), an electronic diagnostics routine is run automatically to check the principal functions. Assuming the appliance is in perfect working order on completion of the self-diagnosis routine, the display shows the main menu. • If any irregularities are discovered, on the other

hand, these are indicated on the display. • Alarms are divided into two categories based on the

type of fault.

“SERIOUS” alarms are signalled by a window with

the message “ALARM” and a steady acoustic signal; these halt the oven completely and shut down all functions. (fig. 1600)

16.2 "SAPIENS" BOARD • Whenever the appliance is powered up by pressing

the main switch, an electronic diagnostics routine is run automatically to check the principal functions. Assuming the appliance is in perfect working order, the oven temperature display shows the actual temperature in the oven, and the LEDs of the cooking mode keys all blink. At this point the cooking parameters can be entered. • If any irregularities are discovered, on the other

hand, these are indicated in the displays. Error codes are extremely important when trouble cannot be remedied by the operator, since they give the service technician an indication as to the nature of the fault. The message on the display is accompanied by a beep of 5 seconds, repeated every minute, until the oven is switched off.

ATTENTION Unlike the "Naboo" version, access to "SERVICE" section in the "Sapiens" version always happens with oven off; so even if an alarm appears preventing any operation from being carried out, switch-off the oven and solve it by accessing the "SERVICE" section.

SOLUTION

The appliance always warns you if there is insufficient water. If the long minimum level probe “Min lev” (alarm) ceases to be immersed in water, the boiler controls are disabled and the warning light comes on. A no water in the boiler signal is given only if there an amount of time "t" (defined by parameters) has passed since the end of the drainage phase and boiler wash or at the start of a steam or mixed cycle. In versions with vaporizers, the signal is managed by the minimum pressure switch "PW" (pressure switch water) and the various parameters set.

• Check that the water cock is

open • Check there is water in the mains

with the aid of the hand-held shower (where applicable). For ovens equipped with steam generator: • Check the motorized valve V1 is

closed (Chap. 9.3) • Check the level probes (electri-

cal connection and cleanliness) • Check solenoid valve S2 (electri-

cal connection/coil) chap. 9.1 • Replace the pc board on electro-

PROBLEM

SOLUTION

An excessive temperature rise registering in the electrical components compartment could result in damage to components. Switch off the oven immediately. The response to overheating is detected by input SPC. Once the threshold defined in the parameter par 21 (see Attachment 2) "high temperature threshold" has been exceeded, the first high temperature message appears. If the temperature increases further, once it exceeds the threshold defined in parameter 22 (Attachment 1) "very high temperature threshold", a second message appears, which is a “serious” alarm; the pc board stops definitively and it is not possible to run a new cooking or preheating cycle until normal conditions have been restored. Message 2 will appear only in case fast cooling mode with door open is activated (led fast cooling button activated) while door is not totally open. This alarm interrupts cooling to avoid hot air flow towards the electronic board. In this case, switchoff oven, fully open the door and wait a few minutes for the board to cool down and switch-on the oven again. For details on correct installation, see chap 6

The flow of air into the combustion chamber is controlled by the fan; in the Venturi tube, the flow of air generates a pressure drop, and the burner flame is modulated by controlling the air flow. The gas flow will follow the air flow according to preestablished ratio by the adjustment of the “TROTTLE” screw also called MIX adjustment.

Unlike atmospheric burners, with which the gas injected into the Venturi unit drew in the air necessary for combustion, with pre-mixed burners the injected air conveys the gas necessary for combustion through the Venturi unit. The Venturi unit shown schematically in fig. 1703 works on the basis of the pressure difference between the high pressure of the air at th e mouth of the fan (pressure in the fan rotor) and the low pressure connected with the output of the gas valve (valve

17.5 GAS OVEN - BURNER MANAGEMENT - ONLY FOR BOARD "SAPIENS" VERSION NOTE: In the oven in question

(combi gas oven with boiler) there is 1 burner for the cooking chamber and 1 for the boiler; in the case of lager ovens they may be up to 2 burners for the cooking chamber and 2 for the boiler. For numeric values, we refer to a GN1/1 10 pans oven, gas powered G31 (LPG). Press the button (Fig. 1729), using the scroller, display writing “REL” and confirm (Fig. 1730). Again, using the scroller, display password 123 and confirm. After the relay and Buzzer list, we enter the burners management section, meaning the writing“br1” appears (Fig. 1731); now we can check, set-up, amend the settings relating to "set" set for the various ignition stages, minimum and maximum speed of the burner. To amend the values of the chamber burner “br1” enter the corresponding section; to do this use the temperature knob to display “br1” and subsequently press the same knob to enter (fig. 1731). The value of the 110 Hz IGN ignition speed appears corresponding to parameter 151 (fig. 1732). To amend press the time knob and change the value by turning the scroller.

IMPORTANT: To save the value press the time knob, whereas to exit press the buttom This change (increase or decrease of the ignition frequency) could be necessary in order to optimise ignition of the oven, preventing “vibrations” and “resonances” during burner ignition.

17.6 GAS OVEN - BURNER ADJUSTMENT - CHECK ANOMALIES Check a complete cycle of ignition, reaching the max burner fan speed "VMax" Hz, switching off, so as to ensure that there are no bursts or resonance during lighting, both from cold and when hot. POSSIBLE TROUBLE DURING THE PHASE OF BURNER IGNITION Explosions / Spluttering:there is excess combustion

of primary air and an insufficient supply of gas. If this phenomenon onlyignition occursspeed in theIqn ignition gradually decrease the Hz; ifphase, this is not successful, turn the Mix screw anticlockwise (a quarter of a turn at a time) so as to increase the supply of gas for combustion. The input pressure at the INgas valves must always be verified in order to evaluate the flow rate of the gas supply line with the burners on. NOTE: incorrect positioning of the spark plugs is the cause of delayed burner ignition with subsequent explosion caused by the accumulation of unburned gas; See Chap. 17.1 to verify the position / distance of the spark plug from the central electrode for burner priming. In this case, removing the burner may turn out to be useful in order to check tions directly. See chap. 17.8 the required condiBURNERS BLOCK SITUATION FOR ELECTRONIC OVENS: • After 10 seconds (burner ignition electrode activa-

tion time), if the flame is not detected, discharge deactivates and the gas valve de-excites; the signal of 230 Volts at contact appears “isolated phase input” of the relay basic board. After 10 seconds (parameter 113 burners block signalling delay), as there is no flame detection, the contact opens and works as thermostat of the SF relay basic board (disconnects voltage to two-stage adjustment electronic board) and the fan stops. • After another 5 seconds, the "reset flame" of the same SF relay basic board automatically activates for aignition fractioncontrol of a second, restore neutral to gas unit, atgiving the same time as automatic burner ignition procedure activation. • After three attempts, the wording "burners block" appears, see CHAP. 14.16. The START key is used to re-activate P burner ignition, regardless of the reaching or not of the cell temperature

17.9 GAS OVEN - NEW ATTACHMENT SYSTEM Starting on June 1, 2012, a new type of bolt entered into production, created to improve the clamping of the burner flanges, to avoid the unscrewing of bolts due to thermal expansion and to compensate for any shrinkage of the sealing gaskets.

1790

The nuts were thus changed from the normal "METRIC BOLTS" to "BOLTS WITH ROTATING SPRING WASHER" (Fig. 1790). The nuts must be tightened with a precise tightening torque that ensures they are correctly closed and the uniformity of the load on all of the nuts, therefore SERVICE must have the proper TORQUE WRENCH (LAR99000260) In order to obtain the correct torque, the BOLT must be subject to an optimal preload force: • If the preload force is too weak, the joints could loosen; • If the preload force is too strong there will be stress on the bolt and components with deformation and the risk of breakage.

ATTENTION For ovens produced before the month of June 2012, we recommend replacing the nuts during expansion visits and/or during periodic oven maintenance. When replacing, also check the integrity of the mounting studs on the exchanger and the condition of the cooking chamber; there must be no visible breakage

22.0 AUTOMATIC WASHING SYSTEM The automatic washing system has a rotating arm (2 arms for mod. 201 - 202) which has a washing head attached that sprays the water or detergent directly in the cooking chamber. For models 071-072-101-102, the "Solid Clean" detergent (or "SolidCal" for Cal-out) is dissolved inside the 2 drawers located on the lower part of the oven.

2200

To refill the drawers with "Solid Clean" and "SolidCal" following a warning when a washing program starts, follow the procedure below: •

Manually remove the drawers

•

Unscrew the caps

•

Screw the containers (the size of the rings are different so they cannot be confused)

•

In automatic mode, the water jet is generated which will hit the inside of the containers, dissolving the product

•

Wait for the message that the operation is complete before unscrewing the containers, replace the caps and close the drawers.

22.6 "NABOO" BOARD - BOILER DESCALING The section in question lets you activate the semiautomatic “Boiler descaling” program by introducing the scale-remover; this operation must be implemented when “LIME SCALE” appears on the electronic board display.

2219

2220

2221

2222

ATTENTION Unlike Calout, the need to descale boiler is less frequent and calculated by the electronic board according to use frequency of the steam and combi modes. We recommend having this program performed for the first time by the authorised technical service. Then activate the “boiler washing” program within 15 days from when the "LIME SCALE" message appears, otherwise when the time elapses the boiler function is automatically disabled and the steam is produced by water being introduced into the oven just like oven versions with direct steam. The operation is made of some automatic cycles and, by pressing the START/STOP button, the 1st cycle is started entailing the draining of the boiler; for this operation the driven valve will automatically open (fig. 1402). A message will subsequently appear, “INSERT BOILER DESCALER”, that will indicate to pour the red coloured DS010 pure scale remover (fig.1403). The solubility percentages indicated by the manufacturer compared to boiler capacity are reported in table: e.g., if wanting to dilute 20% of scale remover on a 10 trays electric oven, 2.6 l of pure scale remover must be introduced when requested. To exceed in the quantities does not mean accelerating the descaling process. The scale remover must be poured inside appropriate boiler inlet (fig. 1401).

ATTENTION The descaler absolutely must be the one recommended by the manufacturer, "DS010". This product does not damage the parts of the steam generator. The descaler must not be spilled carelessly outside the opening (fig. 2221), as it could damage the electrical parts inside the

IMPORTANT: the cycle sequence ensure the complete cleaning of the steam generator, any anomalies signalled during the program makeTHE APPLIANCE UNUSABLE UNTIL AN AUTHORIZED TECHNICIAN INTERVENES. For this reason, we recommend that

the de-scaling is activated in the presence of the authorizedprogram technician.

ATTENTION The operator must strictly supervise the carrying out of this operation! The operator must scrupulously follow the precautions (mask, gloves, etc.) relating to product use!! The descaling operation must not be interrupted! Interrupting the descaling program voids the entire process, with scale remover waste, risk of contamination, if the scale remover has not been completely removed from the boiler. We recommend accurately rinsing the cooking chamber at program end using the hand-held shower.

FOR EXCLUSIVE USE OF THE AUTHORISED TECHNICIAN If required, the following operation must only be carried out by a specialised technician. In case of incorrect activation, the program can be deactivated by simultaneously pressing the scroller for a few seconds; it will be appear the messagge "insert password". The boiler wash must then be redone as some residual descaler may remain which could than go into the cooking chamber and pollute the food.

Shut off all utilities (electricity, water and gas if connected). Leave the door slightly ajar when the appliance is not in use.

ATTENTION Never use direct or high-pressure jets of water to clean the outside of the oven. Never use corrosive and/or abrasive substances on steel surfaces, and avoid scouring or scrubbing with steel wool or wire brushes, as this could result in irreparable damage. Similarly, aggressive detergents, of non-alkaline formulation containing high percentages of sodium and ammonia, can soon damage the seals, jeopardizing oven efficiency and operation. The outside of the oven should be washed with a sponge and warm water with an ordinary detergent suited to the purpose. Use a specially formulated detergent.
