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 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 turn off the filter pump, the unit should also turn off automatically.
Depending on the initial temperature of the water in the swimming pool and the air temperature, it may take
some time to heat the water to the desired temperature. A good swimming pool cover can dramatically
reduce the required length of time.
Time delay - The heat pump has a built-in 3-minute start-up delay to protect the circuitry and avoid excessive
contact wear. The unit will restart automatically after this time delay expires.
If first power on or additional power interruptions, the heat pump starts 10s later after pressing ‘ON/OFF’
button.
3.4 Condensation
The air drawn into the heat pump is strongly cooled by the operation of the heat pump for heating the pool
water, which may cause condensation on the fins of the evaporator. The amount of condensation may be as
much as several litters per hour at high relative humidity. This is sometimes mistakenly regarded as a water
leak.
