2.4 Irrigation and Storm Run-Off
l
Irrigation water may damage heat pump components. Direct irrigation water away from the heat pump.
l
The heat pump will withstand normal rainfall. Do not allow a roof slope to direct rainwater onto the heat pump.
Have a gutter installed on the roof edge to direct this water away from the heat pump. Or install the heat pump in
another location.
2.5 Water Flow Rates
Maintain water flow rates as indicated. Please note, these specifications relate to the heat pump only. Code-
specified whole system turnover rates must be satisfied.
NOTICE
Failure to heed the following may result in damage to equipment.
l
Water flow exceeding maximum flow rates will negatively affect the total pool filtration performance and may
damage the heat pump. This will not be covered under equipment warranty.

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:
l
HIGH PRESSURE FAULT
l
HP5 SYSTEM LOCKOUT
l
LOW PRESSURE FAULT
l
LP5 SYSTEM LOCKOUT
l
Operate 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 higher than the clean filter pressure typically reduces flow rates. This
requires the filter to be cleaned or back-washed.
l
Keep baskets free of debris. A large quantity of debris in the pump and skimmer baskets can reduce water flow.
l
Check 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.
l
The maximum static pressure (or operating pressure) is 50 pounds-per-square-inch (PSI). These specifications
relate to the heat pump only.
l
Code-specified whole system turnover rates must be satisfied.
