Water Flow Rates - Aquacal GBB Installation Manual

1.4.e 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
Water flow exceeding maximum flow rates will negatively affect the total pool filtration performance and may
l
damage the heat pump. This will not be covered under the 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:
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
l
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.
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
l
pump, will cause insufficient water flow through the heat pump.
The maximum static pressure (or operating pressure) is 50 psi (345 kPa). These specifications relate to the heat
l
pump only.
Code-specified whole system turnover rates must be satisfied.
l
Failure to heed the following may result in damage to equipment.
