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.

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).
