Fan Blades Turn, But Compressor Is Not Functioning

The pool heat pump has a built in delay timer which prevents the compressor from
starting immediately. The delay can be 3 to 5 minutes in duration after the fan blades
have turned. Furthermore if the unit is in defrost mode the compressor will not start
for 3 to 20 minutes.
1. Check that air being discharged from the fan blades is colder than the ambient air.
If the air being discharged by the fan blades is colder, it means that the compressor
is functioning correctly.
2. Turn off the pool heat pump then immediately turn it back on;
3. As soon as the fan blades start turning, wait a minimum of 3-5 minutes. The
compressor should start up after this time and you will be able to identify a
different sound made by the compressor when it starts;
4. If the compressor is functioning, but shuts off immediately, consult the following
section "Compressor Starts and Stops".
5. If the problem persists, call your local Waterco office for assistance.

Compressor Starts And Stops

1. Check that the unit has been installed correctly (refer to installation procedures).
2. Check that the water inlet and outlet of the unit have not been connected
incorrectly.

There Is Water Around The Pool Heat Pump

It is a normal occurrence for water condensation, to be seen running from the unit
base. There will be on average 1 to 1.5 gallons (4 to 6 litres) of condensed water per
hour being discharged from the unit base. In order to avoid water accumulation, you
may use decorative rocks around the concrete slab or a basin under the unit. be sure
that clearances around the unit are respected.
To test the unit and confirm you have no pool water leaking from the unit perform
the following test which is best performed early in the morning and continuing for
the whole day:
1. Turn off the pool heat pump from the circuit breaker and the pool pump.
2. Open the bypass valve. (refer to drawing on page 5)
3. Close the IN and OUT water valves on the unit.
4. restart the pool pump. The pool heat pump must remain OFF.
5. When all of the water around the base of the pool heat pump has dried, open the
water IN and water OUT valves on the pool heat pump.
6. Close the bypass valve to allow full water flow through the pool heat pump.
If water is now seen running from the outside of the pool heat pump or inside the
pool heat pump after a short period of time you should call for service. If no water is
seen after a short period of time it would be assumed the water was condensation
which is normal.

Pool Heat Pump Has Ice Formed On The Evaporator Coil

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 blade does 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 Heat Pump Is Functioning, But Does Not Reach The
Desired Temperature Setting
Improper installation may cause this situation and will need to be corrected by the
owner.
1. ensure the by-pass 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 allowed
to dry before re-starting the pool heat pump to avoid premature ice build up on
the evaporator.
4. Waterco recommend the use of a solar cover to retain heat in 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 water pump must be working
continuously (eg; 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.
