Waterco Electroheat Ultra Manuel D'installation page 17

Code Problem - Action / Remedy
FS, DEF, FS4 Problem: Normal defrost cycle. The fan blades are turning, but
the compressor has stopped. For Electroheat Ultra and Reversible
model, the fan blades do not turn but the compressor runs.
Action / Remedy: Normal during defrost duration.
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 under warranty.
If temperatures are below the minimum temperatures the pool heat
pump should not be operated and must be switched off.
For Electroheat and Reversible (XLR) units, they will automatically
stop without human intervention.
Model
Electroheat Ultra
Reversible (XLR)
All others
For Electroheat model: If the unit carries out 5 consecutives defrost
cycles every 15 minutes or less, the pool heat pump is then put into
protection mode (FS4). During this mode, the fan blade turns for
30 minutes in order to cool the evaporator. The pool heat pump
restarts automatically when the external temperature is at: 34˚F
(1˚C).
For Reversible (XLR) Model: If the unit performs 4 consecutive
cycles (heating and defrost) within 1-hour, the unit goes into
protection mode and alternately displays the water temperature
and the DEF code. The fan motor runs for 30 minutes to cool the
evaporator and then stops. The compressor is always off. The unit
restarts automatically when the outside temperature is 43°F (6°C)
and more.
If the code stays on permanently:
- 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 defrost mode and the installation will need to
be corrected by the owner.

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.
