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.
We also recommend that electrical installation is conducted by a licensed electrician.
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 and adequate
wiring.
Connection: Open the terminal box on the side panel.
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. If you are using a
secondary pump to circulate water from the pool to the heat pump this pump 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 spa), the filtration 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 through it.
After all connections have been made and checked, carry out the following procedure:
1. Switch on the filtration 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 on the electronic control panel. The
unit 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 turning off the filtration pump , the unit should also turn off automatically , if not, then adjust the
flow switch.
5. Allow the heat pump and the filtration 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 degrees 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 heating time & is highly recommended as standard.
Water Flow Switch:
The heat pump is fitted with an automatic flow switch to protect the heat pump from inadequate water flow.
If the pool water level is
higher than 1m above or below the heat pump’s automatic adjustment knob, your dealer may need to
adjust its initial startup.
