Pool Heat Pump Has Ice Formed On The Evaporator Coil; Pool Heat Pump Is Not Heating - Waterco Ultra Guide D'utilisation Et D'entretien

TROUBLESHOOTING

Pool Heat Pump Has Ice Formed on the Evaporator Coil

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 by the
warranty.
If temperatures are below the minimum temperatures the pool heat pump should not be
operated and must be switched off.
For Ultra and Reversible (XLR) units, they will automatically stop without human
intervention.
Atmospheric conditions
Model
must be above
Ultra
32 °F (0 °C)
Reversible (XLR)
43 °F (6 °C)
All others
52 °F (11 °C)
1. IMPORTANT: For safety, switch OFF the circuit-breaker.
2. Allow the ice to melt and then inspect the evaporator to ensure it is free of debris and
leaves.
3. If the evaporator is dusty or dirty, clean it with a light spray of water and allow it to dry (do
not use high pressure, it may damage the evaporator fins).
4. When the unit is dry, you may switch it back ON from the circuit breaker.
5. Ensure that the clearances around the unit are respected.
6. When the unit has been switched ON, ensure the fan motor is working (fan blades will be
turning) while the compressor is operating.
7. If the fan blades do not turn and the compressor is functioning; notify customer service.
**If the pool heat pump requires service, the owner of the pool heat pump will need to ensure
the unit has been switched OFF to allow any ice to melt prior to any technician attending.
Pool water temperature
must be above
50 °F (10 °C)
65 °F (18 °C)

IMPORTANT
Improper installation may cause this situation and will need to be corrected by the
owner.
1. Make sure the bypass valves are in the correct positions to ensure sufficient water flow.
Insufficient water flow will cause the compressor to shut off early.
2. If you have installed a timer or the pool heat pump is equipped with an integrated timer,
be sure it is programmed to allow the pool pump to work for sufficient time in order to
reach the programmed temperature.
3. Ensure the evaporator is cleaned regularly with a light spray of water and allow it to dry
before re-starting the pool heat pump to avoid premature ice build up on the evaporator.
4. Waterco recommends the use of a solar cover to retain heat of pool water. Pools without
covers lose 2 to 3 times more heat than pools with solar covers.
5. Make sure the electronic control of your pool heat pump has been programmed correctly;
during this test the pool heat pump and pool pump must be working continuously (e.g.;
the desired water temperature must be set correctly).
6. If the unit continually fails to reach the desired water temperature, we suggest completing
the following analysis chart and forwarding it to Waterco in order to avoid unnecessary
service fees.
