H. 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) 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,
conrm 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. 4. Next,
check that the reference pressure is in the
range indicated in the Head Pressure table
in the Performance Data section. If it is not
in the proper range, verify the refrigerant
charge.
3) Check that the condenser drain temperature is stable.
