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.
