    INTRODUCTION This manual, together with the operator’s manual, forms the complete edition of the Operation and Maintenance instructions. This manual is intended for the use of the technician. It is forbidden for unqualified and unauthorized personnel to service the autoclave in accordance with the instructions in this manual. Any unauthorized service may result in the invalidation of the manufacturer’s guarantee.

  • Page 6: Tests

    TESTS Installation Tests The service technician shall perform the following preliminary checks before operating the autoclave: Leveling Check Check that the autoclave is leveled. b. Leakage current test Check the precise operation of the earth leakage relay. Continuity Check Check the continuity of the grounding connection. d.

  • Page 7: Water Quality

    Only an authorized technician shall perform the 6-months and yearly tests! WATER QUALITY Water for Generating Steam The distilled or mineral – free water supplied to the sterlizer shall be according to the table below: Physical Characteristics and Maximum acceptable contaminants levels in water or steam, for sterlizers (In compliance with ISO 11134 and ISO 13683).

  • Page 8: In-Out Test

    IN-OUT TEST Before performing any trouble shooting on the autoclave, perform an “in-out test”. In this test the technician tests all the components of the system as follows: 1. Turn on the autoclave. Note: if, for any reason, one of the parameters is corrupted and out of range, the autoclave will perform an automatic reset to the parameters set by the manufacturer upon turning on the autoclave.

  • Page 9: Troubleshooting

    TROUBLESHOOTING a) At the customer’s location, avoid replacing any component, which is not connected to a socket or to a flat cable. If necessary, replace the complete board or box. If problem persists service the autoclave at the service lab. b) Whenever the AJUNC3 board of the complete electrical assembly (CB90030) is replaced without replacing the pressure transducer, or after replacing the pressure transducer, the pressure must be re-calibrated.
