2.2 Disinfection of Chair Hoses 2.2.1 Operations with Distilled Water System

a) Distilled water system consists of distilled water cylinder and selector switch at the front of side case. Water to supply all instruments on the instrument panel is from the distilled water in the cylinder or filtered tap water, so the cylinder must be timely refilled with medical distilled water.  b) The cylinder shall be refilled with distilled water in the following way: 

  Close the air switc switch h on distilled water cy cylinder linder till the air in the cylinder is discharged discharged off.



  Remove the ccylinder ylinder by rotatin rotating g it clockwise and inje inject ct distilled water to the maximum maximum leve level. l.



  Re-mount the ccylinder ylinder by rotatin rotating g it counterclo counterclockwise, ckwise, and the then n open the air switch an and d changechange-over over switch on it. Caution: The distilled water cylinder must not be opened until the air in it has been discharged off. As water/air hoses are connected

to the cylinder cover, perform the operations by holding the cover with left hand and rotating the cylinder body with right hand instead of directly rotating the cover. It is recommended to use distilled water instead of tap water during treatment to avoid effect of any impurity in tap water on service life of the hose line and instruments.

Section 4 - Troubleshooting for U Series

4.1 Overall failure 

  Failure 1: After power-on, the overall ssystem ystem makes no response.

Key point for troubleshooting: 1. Check whether AC 220 power supply output is in good condition. 2. Check whether the 10A fuse at power switch is broken. 

  Failure 2: After power-on, no water or air is supplied to the system.

Key point for troublesh troubleshooting: ooting: Check water source change-over, pressurizing/pressure relief shift is in good position; when water source shift is in tap water position, position, the pressur pressurizing/press izing/pressure ure relief shif shiftt should be in relief position;

when wate waterr source shif shiftt is in distilled

water position, the pressurizing pressurizing/pressure /pressure relief shift should be in pressurizin pressurizing g position.

4.2 Common Failures 

  Failure 1:Operating chair fails to ascend o orr descend

Inspections: Check whether there is AC 24V voltage input at J6 port of chair control board and the spittoon protection switch is triggered. whether ther the two yellow keys can oper operate ate to achieve ascent/d ascent/descent escent of  1)   If there is AC 24V voltage input at J6 port, check whe chair; if not, the control board is likely to have damaged, replace the control board to remove the problem.

2)   If there is not AC 24V voltag voltagee inpu inputt at J6 port, chec check k whether the chair pow power er supply plug on flat cable is in good good connection; if not, tighten the screw.

3)   If there is AC 24V voltage input at J6 port, check whe whether ther the two yellow keys can oper operate ate to achieve ascent/d ascent/descent escent of  chair; if not, check whether spittoon protection switch is triggered by using the following method: Toggle the switch to the left to close it, and the chair can ascend or descend; toggle the switch to the right to open it, and the chair cannot ascend or descend. 

  Failure 2:Operating chair ascend o orr descend a automatically utomatically

Inspections: Inspection s: In case that operating chair ascend or descend automatically, automatically, perform troubleshooting from the following aspects:

1)   Assistant Section Touch Cont Control rol Board: The assistant section control board may be corroded corroded due to damp absorption or  entry of water, and thereby cause malfunction of the function keys. Inspection method: Disconnect the communication cable terminal on the control board, operate the machine by using  pedal and treatment platform to check whether the failure continues continues;; if the failure is removed removed,, it indicates that the control board is damaged, and replace it; if the failure continues, re-connect the communication cable terminal, and go to the next step.

2)   Treatment platfo platform rm touch control board: The treatme treatment nt platform control board may be corroded due to damp absorp absorption tion or entry of water, and thereby cause malfunction of the function keys. Inspection method: Disconnect the communication cable terminal on the control board, operate the machine by using  pedal and treatment platform to check whether the failure continues continues;; if the failure is removed removed,, it indicates that the control board is damaged, and replace it to remove the problem. 

  Failure 5: Handheld sprayer operates n normally ormally but no water or air is sprayed sprayed out.

Inspections:

1)   First check whethe whetherr the blower operates currently in dry grinding grinding mode where no water or air is sprayed by operating the change-over switch on it. For more details see the operating instructions. Check k the wate water/air r/air hose line is in good conne connection ction in instrum instrument ent panel. If the hos hosee line is in good conditio condition, n, then 2)   Chec Check whether there is DC 24V output at water/air circuit solenoid valves; if yes, the solenoid valve may be broken, and replace solenoid valve; if not, measure voltage output at reserved port J33, if there is a voltage output, replace treatment platform control board, if not, inspect the power supply in side case (U200).

3)   Check whether the handh handheld eld sprayer hanging rack valve (hung type type)) on treatment platform and constant-on valve with  peak can reset properly, if not or in i n case of leakage leakage,, replace the relevant valve. (U100)
