3.7 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 you turn off the filter pump , the unit should also turn off automatically, if not 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 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 time.
Water Flow Switch:
It is equipped with a flow switch to prevent the heat pump of running with inadequate water
flow rate. It will turn on when the pool pump runs and shuts off when the pump shuts off. If the
pool water level is more than 1m above or below the heat pump’s automatic adjustment knob,
your dealer may need to adjust its initial startup.
Time delay:
The heat pump has a 3-minute start-up delay to protect the circuitry and avoid excessive
contact wear. The unit will restart automatically after this time delay expires. Even a brief
power interruption will trigger this time delay and prevent the unit from restarting immediately.
Additional power interruptions during this delay period do not affect the 3-minute duration of
the delay.
3.8 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 litres per hour at high relative humidity.
This is sometimes mistakenly regarded as a water leak.
