3.5 Typical arrangement
Note: This arrangement is only an illustrative example.
3.6 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
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 , 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.
3.7 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 liters per
hour at high relative humidity. This is sometimes mistakenly regarded as a water leak.
