Code
Problem - Action / Remedy
LP, LP3
Problem:
Low refrigerant level in the pool heat pump or the low-
pressure safety control is defective.
Atmospheric conditions as well as the pool water temperature should
not be below the minimum operating temperatures as stated below
in order to obtain efficiency and avoid codes from appearing on the
electronic control temperature display ; these codes are not generally
a problem with the pool heat pump at these conditions and is not
covered by the warranty.
If temperatures are below the minimum temperatures listed below the
pool heat pump should not be operated and must be switched off.

Action / Remedy:
- If the LP or LP3 code is shown permanently, press ¨SET¨ or ¨ON/
OFF¨ depending of the model you have before to get to next step;
- Ensure the evaporator is clean. If not switch the unit OFF from
the circuit breaker (fuse) and use a garden hose to lightly clean
the evaporator, then allow it to dry before re-starting the pool heat
pump to avoid premature ice build up on the evaporator.
- Ensure installation instructions have been followed. Improper
installation, e.g. no air circulation could lead to the pool heat pump
continually going into LP or LP3 mode and the installation will need
to be corrected by the owner.
HP, HP3
Problem:
Low water circulation in the unit or the high-pressure
control is defective. If the HP code is triggered and displayed 3
times; this will cause the pool heat pump to shut down automatically.
The HP3 code will then appear permanently (except for reversible
electronic control with diagnostics).
Note: The pool pump will stop functioning only if the internal time
delay of the pool heat pump is being used.
IMPORTANT:
When the code HP3 is permanently displayed, before
performing the steps below, please press the ¨SET¨ button for the
electronic control Multi Function and ¨ON / OFF¨ for the electronic
control with diagnostics and the reversible electronic control with
diagnostics (XLR) and electronic control with diagnostics.
