Water regulating valve setting
The correct setting of the valve is easily determined.
1. Supply cooling water to HX.
2. Direct the outlet hose into a bucket or drain.
3. Turn the HX on.
4. Turn the setpoint to minimum. The HX should enter the cool
cycle. Observe full flow from the outlet hose. Allow it to run
until all air is displaced.
5. Turn setpoint to maximum. The HX should enter the heat
cycle.
6. Adjust the valve stem closed (CCW) until the flow stops.
7. Slowly open the valve stem (CW) until a small but constant
trickle is exiting the outlet hose. This is the point where the
valve is just beginning to crack open. This is the correct
setting.
8. Turn setpoint to minimum. The HX should enter the cool
cycle. Full flow should again be observed from the outlet
hose.
