Code Problem - Action / Remedy
LP 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 are not covered under warranty.
If temperatures are below the minimum temperatures the pool heat pump
should not be operated and must be switched off.
Model
Ultra
Reversible (XLR)
All others
Action / Remedy:
If the LP code is shown permanently, press ON/OFF before getting to the
-
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. 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 mode and the installation will need to be corrected by the owner.
This situation is not covered by the warranty.
HP
Problem: Low water circulation in the unit or the high-pressure control is
defective.
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 HP is permanently displayed, before
performing the steps below please press ON/OFF for the electronic control
with diagnostics and the reversible (XLR) electronic control with diagnostics.

Problem – Action / Remedy
Code
HP Action / Remedy: Make sure the water reaches the pool heat pump and the
pool pump is completely filled to the rim. Otherwise:
Fill the pool pump with water and check to see if the pipes between the
-
pool pump and the pool are watertight (there should be no air intake);
Check the swimming pool and pool skimmer baskets and the drain at the
-
bottom of the pool for obstructions;
Check the filter cartridges for obstructions (wash or change the
-
cartridges, as the case may be);
Insure that the bypass valves are in the correct positions so that the
-
water flows adequately;
Backwash sand filter (insure that there is a sufficient amount of sand and
-
verify that it does not have to be changed. Consult a swimming pool
specialist if necessary);
Make sure the vacuum robot is disconnected so the water flows freely;
-
If you have a two speeds pool pump, make sure that it is set at the
-
highest speed.
