Maintenance Procedure

Warning!

Failure to perform the required maintenance at the frequency specified will void warranty coverage in the event of a related failure.

To insure economical, trouble free operation of the ice maker, it is recommended that the following maintenance be performed every 6 months by a qualified service technician.

1.Check the float reservoir for mineral build-up or check the auger drive motor amp draw to determine if the water system needs cleaning. Clean the water system, if necessary, per the instructions on Page B2. Local water conditions may require that cleaning be performed more often than 6 month intervals.

2.Check the water level in the float tank as described on Page D1.

3.Clean the condenser (air cooled machines) to insure unobstructed airflow.

4.Check for leaks of any kind, water, refrigerant, oil, etc.

5.Check the Primary Bin Control for proper adjustment as described on Page G3.

6.Check the Secondary Bin Control for proper adjustment as described on Page G4

7.Check the Safety Control for proper adjustment as described on Page G3.

8.Check the water requlating valve (water cooled machines) for proper adjustment by measuring the water temperature at the outlet of the condenser drain. It should be between 100°F (37.7°C) and 110°F (43.3°C).

9.Check the TXV bulb to make sure that it is securely fastened and properly insulated.

10.Check all electrical connections tightness. Warning: Disconnect electrical supply.

11.Oil the auger motor if the motor has oil fittings.

12.Check the V-Belt for wear and proper tension as described on Page E1.
