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, confirm 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 flat 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.
