Description
SERVICE MANUAL SINGLE PATIENT DIALYSIS MACHINE
PREFACE Thank you for purchase of Single Patient Dialysis Machine, SURDIAL. The service manual is designed to give information required to check/maintain and repair SURDIAL a qualified service engineer and technician. Any operation or work contained in the manual should be informed by them. They should have knowledge and ability sufficient to replace microprocessor based electronic component with new one, and should have general knowledge concerning fluid lines of dialysis machine. Also they should read and full understand contents of the manual before executing component replacement or maintenance of SURDIAL. Use the manual by referring to the operation manual of SURDIAL. Generally, description common to the both manuals is minimal with exception that the description is contained in some chapters. Information required to operate SURDIAL is contained in the operation manual (and technical information is also found in some chapters) and information related to maintenance, component replacement and various settings of SURDIAL is contained in the service manual.
Description in the service manual is protected by copyright of the manufacturer. Copy, reproduction or preparation of version in any foreign language of the description partially or wholly should not be allowed without obtaining prior approval by the manufacturer.

CAUTION -1
CAUTIONS FOR SAFETY To use the machine (SURDIAL) safely, it shall be operated in accordance with specified procedures and shall be maintained regularly after reading and full understanding cautions included in this Operation Manual. Procedures for operation and cautions for safety contained in the manual are only applicable to the case when the machine is used for specified purpose. It shall be noted that any danger caused by use of the machine based on any procedures not specified in the manual shall be responsible for user. (1) Messages for safety are classified into the following three categories:
DANGER Cases critically causing death or severe injury of user by misuse of the machine WARNING Cases potentially causing death or severe injury of user by misuse of the machine CAUTION Cases potentially causing injury of user and/or loss of property by misuse of the machine (2) NOTE Reference to operation of the machine

CAUTION -2
DANGER
Before use of the machine, read and understand this Operation Manual. • The machine can be used safely and reliably when operated and maintained as specified in the manual. • The machine shall be operated by well trained and qualified person only to avoid danger and/or the machine damage due to incorrect use. Be familiar with procedure how to stop the machine in emergency. • Full understand procedure how to stop the machine to prevent incidence of serious problems. • The machine shall be operated by well trained and qualified person only unless otherwise instructed formally. Be familiar with procedure how to take corrective actions if the machine is stopped by any reason. • Take corrective actions specified in the manual, after checking the machine conditions. DO NOT touch board, wiring and terminal with hand in the case other than maintenance. • DO NOT touch wiring and terminal not insulated. • DO NOT touch board with wet hand. • Turn OFF the power breaker and remove plug when touch terminal. Take the following care to avoid potential danger to patient when blood line connection and disconnection: • DO NOT enter air bubbles into patient body. • DO NOT connect blood line to the patient before completion of priming operation. • DO NOT connect blood line to the patient during rinsing operation. • DO NOT enter harmful virus or chemical into patient body. Check frequently that blood line is connected correctly to avoid danger to patient due to blood leak caused by disconnection of the line when incorrectly connected, and due to rupture of the line caused by excess pressure application.

CAUTION -3
WARNING DO NOT use electric wave generating electronic device in any room or building where single patient dialysis machine is operated. If the device such as portable telephone, transceiver or radio control toy is operate or used in any place in hospital, malfunction of instrument used for medical treatment may be caused. Manage and instruct any person not to bring or use any electric wave generating device in hospital to avoid any failure. DO NOT change parameter setting during dialysis excluding the case of emergency. Change parameter setting before connecting with patient. Set parameter as intended after full understanding its function. DO NOT touch power cable on the floor to prevent electric shock due to fluid beak caused by the machine trouble. Provide drain port near the machine. DO NOT touch switch unnecessary for the machine operation during dialysis. DO NOT incline the machine at an angle 5° (Maximum) under loading any object on container support or hunger to prevent falling down of the machine. DO NOT load any object during transport. DO NOT incline the machine at an angle of 10° (Maximum) under no load to prevent falling down of the machine.

Perform UF test to check that UF error is within specified range. Measure conductivity to check that difference between the measured one and set one is within specified range. Check that measured blood pump flow rate is within ±5% of set flow rate. Check also that temperature control is normal and dialysate temperature is stabilized.
WARNING •
DO NOT change "19.ROLLING TUBE TYPE" during dialysis to avoid trouble.
CAUTION •
BP flow rate calibration (GAIN and OFFSET) values are those determined using standard NIPRO blood line. When blood line of smaller sized or other manufacturer is used, adjustment is required. Also when blood line of smaller sized is used, adjust gap between BP rotors and housing.
