Adjustment Of Water-Regulating Valve; Water Cooled Model Only - Hoshizaki KM-280MAF-E 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 thermom-
eter to check for the condenser drain temperature.
2) Rotate the adjustment screw by using a flat blade screwdriver, so that the pressure
gauge shows 18.4 BAR or the thermometer reads 104-115 °F (40- 46°C), 5 min-
utes after a freeze cycle or icemaking process starts. When the pressure exceeds
18.4 BAR, or the condenser drain temperature exceeds 115 ° F (46 °C), rotate the
adjustment screw counterclockwise. See Fig. 1.
3) Check that the pressure or the condenser drain temperature holds a stable setting.
