General Maintenance Procedure
To insure economical, trouble free operation of your machine, it is recommended that the
following maintenance be performed every 6 months.
1. Clean the ice-making section per the instructions below. Cleaning should be performed a
minimum of every 6 months. Local water conditions may require that cleaning be
performed more often.
2. Check ice bridge thickness.
3. Check water level in trough.
4. Clean the condenser (air-cooled machines) to insure unobstructed air flow.
5. Check for leaks of any kind: Water, Refrigerant, Oil, Etc.
6. Check the bin control switch for proper adjustment.
7. Check the water regulating valve (water cooled machine) for proper adjustment by
measuring the discharge pressure which should be adjusted to maintain 250 psi (17.01
bar / 1.723 MPa). Adjust the water regulating valve as required. Water exiting the condenser
should be between 100°F (38°C) and 110°F (43°C).
8. Check all electrical connections.
9. Oil the fan motor if the motor has an oil fitting. (Self-contained air-cooled models only)
10. Check the water filter (if applicable) and replace if dirty or restricted.
11. Inspect the evaporator water distribution tube to insure even distribution of water across
the face of the evaporator.
