8. ADJUSTMENT OF WATER REGULATING VALVE - KM-151BWH 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, confi 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 fl 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.
