Start-up procedure
After the installation is completed, you should follow these steps.
1.
Set the by-pass valve 1 entirely open. Turn on your filter pump. Check for water leaks
and verify flow to and from the pool.
2.
Turn on the electrical power supply to the unit and turn the unit ON with the switch.
Slightly close valve 1 until the heat pump starts.
3.
After running a few minutes, check if the air leaving the side of the unit is cooler.
4.
Check the performance of the flow switch as follows: with the unit running, turn the
filter pump off. The unit should also switch off automatically. If not, the flow switch
must be readjusted.
5.
Allow the unit and pool pump to run 24 hours per day until desired pool water
temperature is reached. When the set temperature is reached, the unit just shuts off.
The unit will now automatically restart (as long as your pool pump is running) when
the pool temperature drops more than 1° C below set temperature. It can take several
days for the water to reach the desired temperature. Covering the pool can drastically
reduce this period.
Water flow switch
- the unit is equipped with a flow switch that is switched on when
enough water has flowed through the unit and that is switched off when the water flow
becomes too low. e g. when the filter pump is switched of.
Time Delay
- the unit is equipped with a built-in 3-minute start delay to protect electrical
components and contacts. After this time delay, the unit will automatically be restarted.
Even a brief interruption of the power supply will activate the start delay and prevent the
unit from starting immediately. Additional interruptions of the power supply during the
delay period will have no effect on the 3-minute countdown.
Daily use of the heat pump
The heat pump can be switched on an off via the on-off switch. The heat pump can also be
connected to the same power grid as your filtration pump, so that the heat pump is
switched on automatically as soon as the filtration pump is switched on.
Under 8°C, a low temperature alarm will stop the heat pump functioning to prevent
freezing of the heat pump.
Under normal conditions of flow, the heat pump will heat the pool water by 0.25-1 deg per
pass.
Condensation
Since the heat pump cools down the air about 8 - 12 °C, water may condense on the fins of
the evaporator. If the relative humidity is very high, this could be as much as several liters
an hour. Sometimes this condensation water is wrongly considered as a water leak of the
swimming pool water. If water, collected from the heat pump, contains chlorine, it is
swimming water.
