3.4 Electrical wiring
Note:
Verify the local power supply and the operating voltage of the heat pump. It is recommended to use
the included separate circuit breaker for the heat pump, together with the proper wiring characteristics (see
wiring diagram). The current to the heat pump should only be applied when the filter pump is running.
Further connect the electrical supply to the junction box inside the unit. All ECO heat pumps require single-
phase connection.
Grounding:
The circuit breaker protects you against electrical shock caused by a possible short circuit
inside the unit. The heat pump in itself is unable to provide a water flow. Therefore, the heat pump must be
wired electrically together with the filter pump to ensure a water flow while the heat pump is running.

3.5 Initial start-up
Startup procedure
After the installation is completed, you should follow these steps:
1. Open bypass valve 1 entirely. Turn on your filter pump, check for water leaks and verify the flow to
and from the pool.
2. Turn on the electrical power supply to the unit, then turn the unit ON with the switch. Slightly close
valve 1 until the heat pump starts.
3. After a few minutes, check if the air leaving the unit is cooler.
4. Allow the unit and filter pump to run 24 hours a day until the desired pool water temperature is
reached. When the set temperature is reached, the unit shuts off. The unit will now automatically
restart (as long as your pool pump is running) when the temperature of the pool water drops more
than 1°C below set temperature
.
Several days are needed to bring the temperature of your swimming pool water to its required value.
Covering the pool or the use of ground insulation can drastically reduce this period.
Time delay
The unit is equipped with a built in 3-minute start delay to protect the control circuit components and to
eliminate restart cycling an contactor chatter. This time delay will automatically restart the unit aproximately
3 minutes after each circuit interruption. Even a brief power interruption of the power supply will activate
this delay and prevent the unit from starting until the 3-minute countdown is completed.
