Adjustment Of Water Regulating Valve - Water-Cooled Model Only; Water Cooled Model Only - Hoshizaki KM-500MAF Service Manual

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 270 PSIG, or the
condenser drain temperature exceeds the temperature range, rotate the adjustment
screw counterclockwise. See Fig. 1.
3) Check that the pressure or the condenser drain temperature holds a stable setting.
