1. Turn on the filter pump, check for leaks and verify flow to and from the pool.
2. Turn on the electrical power supply to the unit, then press the ON/ OFF key on the electronic control
panel. The unit should start when the time delay period has lapsed .
3. When the unit has been running for a couple of minutes, check if the air leaving 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. All the unit and filter pump to run 24 hours a day until the desired pool water temperature is reached.

the filter pump is switched off
When the set temperature is reached, the unit switches itself off. The unit will now automatically restart
(as long as your filter pump is running) when the temperature of the pool water experiences a drop of
more than 1
℃
below set temperature
.
Depending on the starting temperature of the pool water and the air
temperature, it can take several days for the water to reach the desired temperature. Covering the pool
can drastically reduced this period.

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.

3.6 Electrical wiring
Note:-Verify the local power supply and the operating voltage of the heat pump. It is recommended to use
a separate circuit breaker(slow type-D curve)for the heat pump together with the proper wiring characteristics
(see table below). The current to the heat pump should only be applied when the filter pump is running. For
example a relay controlled by the filter pump could be used to activate the current to the heat pump. Further
connect the electrical supply to the junction box inside the unit. All PRO heat pumps require single-phase
connection.
Grounding
the heat pump is required to protect you against electrical shock caused by an eventual short
circuit inside the unit.
The heat pump is not equipped with a flow switch or any other kind of water flow detection. Therefore, the
heat pump has to be wired electrically together with the filter pump to ensure water flow while the heat pump
is running.

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.
3.3.8 9 Condensation
When the swimming pool water is being heated by the heat pump, the incoming air is cooled down quite a
bit, which can cause condensation on the fins of the evaporator. Condensed volumes can attain severa l
litres per hour underhigh atmospheric humidity. Sometimes, this is wrongfully interpreted as a water leak.
