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.

TROUBLESHOOTING
Please ensure the unit and any related equipment is installed in accordance with the
installation manual. If not, the Waterco warranty will not apply and the customer may
be liable for service call charges.
Nothing Is Working And The Electronic Control
Does Not Operate
1. Ensure the circuit-breaker has not tripped and/or the fuses have not blown;
**Take note that only an electrician can verify if the circuit breaker is defective;
if this is the case, repairs will not be covered under the warranty.
2. For three phase models, this situation could occur when phases are not in the appropriate
order. The green led light on the front panel will not light up.
Please have a qualified electrician swap over two of the incoming phase wires.
Nothing Is Working But The Electronic Control
Temperature Displays Digits Or A Code
1. Identify the analyser code that the electronic control displays and refer to the
Service Analyser codes section;
2. If the electronic control displays digits, make sure that the electronic control
is programmed correctly, refer to the Operation of your pool heat pump and
reprogram if necessary.
**Note that this situation could occur when the electrical voltage is not respected
as stated on the pool heat pump name plate. This situation is not covered by the
manufacturer warranty.
Fan Doesn’t Work (the fan blades are not moving)
1. IMPORTANT: For safety, switch OFF the circuit-breaker.
2. Try to rotate the fan blades of the fan with a rod to see if the motor is jammed or seized
3. If the fan blades do not turn freely leave the unit switched OFF and call for service;
4. If the fan blades turn freely switch ON the circuit breaker and the pool heat pump again.
** Note that your fan motor may have an electrical fault if the blades turn freely when the
unit is switched OFF and does not start when the unit is switched ON.
