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 the temperature specified in the table, 5 minutes after a freeze cycle or icemaking process starts. When the pressure exceeds 235 PSIG, or the condenser drain temperature exceeds the temperature range, rotate the adjustment screw clockwise. See Fig. 1.

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