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.

 

  • 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:

  • HP and HP5
  • or (if equipped) error codes of LP and LP5
  • 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.
  • Keep baskets free of debris. A large quantity of debris in the pump and skimmer baskets can reduce water flow.
  • 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.
  • The maximum static pressure (or operating pressure) is 50 pounds-per-square-inch (PSI). These specifications relate to the heat pump only.
  • Code-specified whole system turnover rates must be satisfied.
