If water flow through the heat pump is reduced, performance will suffer and internal safety devices may
deactivate the heat pump with error codes HP and HP5, or (if equipped) an LP and LP5.
l Operate water filtration devices per manufacturer's specifications. Dirty filters can cause reduced 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. Similar to a dirty filter, large volumes 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 (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.
3.3.c Adjusting Water Flow Using ΔT (Delta-T)
The Delta-T is the temperature difference between the water temperatures entering and leaving the heat
pump. The equipment can be fine-tuned for maximum performance by balancing water flow rates to
maintain an ideal ∆T.
l Installed Temperature / Pressure probes and ports are required to perform the following procedures.
l
This adjustment procedure is to be completed with the unit in HEA mode only; ACH and COO discharge
temperatures are not shown.
PLEASE NOTE -
Temperature / Pressure ports are required for all commercial applications.
They are strongly recommended (but not required) for residential installations.

Light Freeze Conditions
There are two freeze conditions requiring heat pump attention. A light freeze is when the ambient air
temperature falls below 32 degrees Fahrenheit for less than 8 hours. Typically during light freeze conditions
circulating (moving) water will not freeze. Override time clocks and allow filtration system to run
continuously during light freeze conditions.
Hard Freeze Conditions
A hard freeze is when the ambient air temperature falls below 32 degrees Fahrenheit for more than 8 hours.
In areas where this condition is prevalent and sustained, the heat pump MUST be winterized for hard freeze
conditions. Follow the correct procedure depending on the type of heat exchanger found in the heat pump.
Identify Exchanger:
1.
Deactivate all electrical power to heat pump.
2.
Deactivate filter pump.
3.
Remove front access panel.
4.
Identify heat pump exchanger from illustrations in this section. Then follow procedure for that heat pump's
exchanger.
