WATER VALVE ADJUSTMENT
All AQUACOOLER units come equipped with automatic pres-
sure 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 recommended
that the water valve be adjusted.
1. Disconnect the unit power.
2. Remove the unit back panel and locate the water regulat-
ing 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
