WATER VALVE ADJUSTMENT
All OWC units come equipped with an automatic pressure
regulated water valve which controls the condenser water flow
rate. The water valve will open when the system is running,
and will adjust the water flow rate based on the temperature of
the supply water.
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
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
CCW
to raise the low
side operating pressure...or...
CW
to lower the low side
operating pressure.
5. Re-install the back panel and turn the unit on.
