3.7 Electrical connection

Note: Although the heat pump is electrically isolated from the rest of the swimming pool system, this
only prevents the flow of electrical current to or from the water in the pool. Earthing is still required
for protection against short-circuits inside the unit. Always provide a good earth connection.The
installer must consult the electricity provider if necessary and ensure that the equipment is
connected correctly to an electricity network with impedance under 0.095 ohm.
Warning : Before any work inside the appliance, you must cut the appliance's electricity supply as there is a
risk of electric shock which may cause material damage, serious injury or even death.
• Incorrectly tightened terminals may cause the terminal box to heat up, which can invalidate
the warranty.
• Only a qualified and experienced technician is authorised to carry out cabling work within the
appliance or to replace the power cord.
Before connecting the unit, verify that the supply voltage matches the operating voltage of the heat pump.
It is recommended to connect the heat pump to a circuit with its own fuse or circuit breaker (slow type; curve
D) and to use adequate wiring.
Connect the electrical wires to the terminal block marked ' POWER SUPPLY '.
A second terminal block marked 'WATER PUMP ' is located next to the first one. The filter pump (max. 5 A
0 V) can be connected to the second terminal block here. This allows the filter pump operation to be
controlled by the heat pump.

3.8 Initial operation

Note: In order to heat the water in the pool (or hot tub), the filter pump must be running to cause the
water to circulate through the heat pump. The heat pump will not start up if the water is not
circulating.
After all connections have been made and checked, carry out the following procedure:
1. Switch on the filter pump. Check for leaks and verify that water is flowing from and to the swimming pool.
2. Connect power to the heat pump and press the On/Off button
will start up after the time delay expires (see below).
3. After a few minutes, check whether the air blowing out of the unit is cooler.
4. When turn off the filter pump , the unit should also turn off automatically , if not, then adjust the flow
switch.
5. Allow the heat pump and the filter pump to run 24 hours a day until the desired water temperature is
reached. The heat pump will stop running at this point. After this, it will restart automatically (as long as
the filter pump is running) whenever the swimming pool water temperature drops 2 degree below the set
temperature.
Depending on the initial temperature of the water in the swimming pool and the air temperature, it may take
several days to heat the water to the desired temperature. A good swimming pool cover can dramatically
reduce the required length of time.
