TROUBLESHOOTING
12/2016
8-8
Symptom: High discharge pressure (check gage accuracy)
Possible Cause
Possible Remedy
Insufficient water flow through the cooling
tower or condenser
Check the condenser water pump to make sure
it is pumping enough water as specified in Page
3-13. Check sump strainer screen and clean.
Check condenser pump direction of rotation.
Fan control out of adjustment
Check adjustment. Replace if defective.
Non-condensable in system.
If non-condensables are present with the
refrigerant, the saturated temperature will not
relate to the pressure reading at the receiver.
The refrigerant will be cooler, although the
pressure will be high. Air can be purged from
the system by following instructions in Chapter
9, “Purging Non-Condensables”.
Cooling tower or evaporative condenser in
need of maintenance
Check fan motor and fan belts for proper
operation and tension. Check spray nozzles,
tubes,
sump,
and
sump
screen,
for
accumulation of mineral deposit and clean as
required. Check tower blowdown and
chemical treatment if applicable.
Dirty condenser tubes
Visually inspect the condenser tubes to see if
there is any build-up of mineral deposit, which
would reduce the cooling effect of the tubes
and water. Clean chemically or mechanically
as applicable.
Too much liquid in condenser covering tubes
causing inefficiency
Remove refrigerant so all tubes will be above
liquid refrigerant level.
