PLEASE NOTE -
If minimum flow rates are not met, heat pump performance is reduced and performance
will suffer. Internal safety devices may deactivate the heat pump with the following
errors:
lHIGH PRESSURE FAULT
lHP5 SYSTEM LOCKOUT
lLOW PRESSURE FAULT
lLP5 SYSTEM LOCKOUT
lOperate water filtration devices per manufacturer's specifications. Dirty filters can cause a reduction of water
flow to the heat pump. An increase of 7-10 psi (48 to 69 kPa) higher than the clean filter pressure typically
reduces flow rates. This requires the filter to be cleaned or back-washed.
lKeep baskets free of debris. A large quantity of debris in the pump and skimmer baskets can reduce water flow.
lCheck for improper valve settings. A partially closed valve after the filter, or a full-open bypass around the heat
pump, will cause insufficient water flow through the heat pump.
lThe maximum static pressure (or operating pressure) is 50 psi (345 kPa) unless a special "high-pressure" unit
