WATER VALVE ADJUSTMENT
All POLARIS units come equipped with automatic pressure regulated water valves, that
control the condenser water flow rate. The water valves will open when the system is
running and will adjust the water flow rate as required by the air conditioning system.
In some cases, water temperatures can cause the valve to open and close at a high rate,
causing a “chattering” condition in the water supply line. In these cases, it is recom-
mended that the water valve be adjusted.
1. Disconnect the unit power.
2. Remove the unit back panel and locate the water regulating valve in the lower right
region of the unit.
3. Locate the water valve adjustment screw. At the top of the valve there is a square-
shaped adjustment screw.
4. Turn the adjustment screw 1/4 turn, re-start the unit, and observe operation to see if
the “chattering” goes away. Make 1/4 turn adjustments and observe the unit operation
until the condition goes away.
5. Close up the unit and POWER
