IV. ADJUSTMENT OF COMPONENTS
1. ADJUSTMENT OF WATER REGULATING VALVE - WATER-COOLED
MODEL ONLY
The Water Regulating Valve also called “WATER REGULATOR” is factory-adjusted. No
adjustment is required under normal use. Adjust the Water Regulator , if necessary, using
the following procedures.
1) Attach a pressure gauge to the high-side line of the system. Or prepare a thermometer
to check the condenser drain temperature.
2) Rotate the Adjustment Screw by using a flat blade screwdriver, so that the pressure
gauge shows 260 PSIG (R-404A models/-F type), or the thermometer reads 100 -104°F,
in 5 minutes after the icemaking process starts. When the pressure exceeds 260 PSIG,
or the condenser drain temperature exceeds 104°F, rotate the Adjustment Screw
counterclockwise.
3) Check that the pressure or the condenser drain temperature holds a stable setting.
