11. ADJUSTMENT OF WATER REGULATING VALVE (WATER-COOLED
MODEL)
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) Prepare a thermometer to check the condenser drain temperature. Attach a pressure
gauge to the high-side line of the system.
2) Five minutes after a freeze cycle starts, con rm that the thermometer reads 104°F to
115°F (40°C to 46°C). If it does not, rotate the adjustment screw by using a at blade
screwdriver until the temperature is in the proper range. See Fig. 7. Next, check that
the reference pressure is in the range indicated in the Head Pressure table. See “III. 4.
PERFORMANCE DATA”. If it is not in the proper range, verify the refrigerant charge.
3) Check that the condenser drain temperature is stable.
