9. 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 for the condenser drain temperature.

2) Rotate the adjustment screw by using a flat blade screwdriver, so that the pressure gauge

shows 270 PSIG or the thermometer reads 104–115° F, 5 minutes after a freeze cycle or

icemaking process starts. When the pressure exceeds 270 PSIG, or the condenser drain

temperature exceeds 115° F, rotate the adjustment screw counterclockwise. See Fig. 1.

3) Check that the pressure or the condenser drain temperature holds a stable setting.
