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.
