3.5 Electrical Wiring
Important - Although the heat pump is electrically isolated from the rest of the unit, this
only prevents the passage of electricity to or from the pool water. Grounding the unit is still
required to protect yourself from short circuits inside the unit. Make for adequate ground
connection.
Check if the electrical mains voltage corresponds with the operating voltage of the heat pump
prior to hooking up the unit.
It is recommended to use a separate fuse (C-curve) as well as adequate wiring (see table below).
Connect the electrical wires with the terminal block labelled ‘TO POWER SUPPLY’.
Next to this connection, the
re is a second terminal block labelled ‘TO PUMP’, to which the filter
pump (max. 5A/240V) or an electrical relay for a filtration pump can be connected. This
connection makes it possible to control filter pump operation with the heat pump.

3.6 Initial startup of the Unit
NOTE- In order for the unit to heat the pool or spa, the filter pump must be running to
circulate water through the heat exchanger.
Start up Procedure - After installation is completed, you should follow these steps:
1. Turn on your filter pump. Check for water leaks and verify flow to and from the pool.
2. Turn on the electrical power supply to the heat pump, then press the key ON/OFF of wire
controller, It should start in several seconds.
3. After running a few minutes make sure the air leaving the fan opening of the unit is cooler
(between 5-10°C)
4. With the unit operating turn the filter pump off. The unit should also turn off automatically,
5. Allow the unit and pool pump to run 24 hours per day until desired pool water temperature is
reached. When the desired pool water temperature reaches the setting, the unit just shuts off.
The unit will now automatically restart (as long as your filter pump is running) when the pool
temperature drops more than 2°C below set temperature.
Time Delay- The unit is equipped with a 3-minute built-in solid state restart delay included to
protect control circuit components and to eliminate restart cycling and contactor chatter.
This time delay will automatically restart the unit approximately 3 minutes after each control
circuit interruption. Even a brief power interruption will activate the solid state 3 minute
restart delay and prevent the unit from starting until the 5 minute countdown is completed.
Power interruptions during the delay period will have no effect on the 3 minute countdown.
