5. Operation
5.1 Operation
Conditions of use
For the heat pump to operate normally, the ambient air temperature must be between 7°C and 43°C.
Recommendations prior to start-up
Before activating the heat pump, please:
✔ Check that the unit is stable.
✔ Check that the gauge indicates a pressure greater than 80 psi.
✔ Control the proper functioning of your electrical installation.
✔ Check that the hydraulic connections are tight and that there is no leakage of water.
✔ Remove any unnecessary object or tool from around the unit.
Operation
1. Connect the unit power plug.
2. Activate the circulating pump.
3. Activate the unit’s power supply protection (differential switch and circuit-breaker).
4. Activate the heat pump by pressing once on .
5. Select the required temperature.
6. The heat pump’s compressor will start up after a few moments.
All you have to do now is wait until the required temperature is reached.
WARNING: Under normal conditions, a suitable heat pump can heat the water in a swimming
pool by 1°C to 2°C per day. It is therefore quite normal to not feel any temperature difference in
the system when the heat pump is working.
A heated pool must be covered to avoid any loss of heat.
20
5. Operation
5.2 Using the pressure gauge
The gauge is for monitoring the pressure of the refrigerant contained in the heat pump.
The values it indicates can vary considerably, depending on the climate, temperature and atmospheric
pressure.
When the heat pump is in operation:
The gauge needle indicates the refrigerant pressure.
Mean operating range between 120 and 400 PSI, depending on the ambient temperature and atmospheric
pressure.
When the heat pump is shut down:
The needle indicates the same value as the ambient temperature (within a few degrees) and the corresponding atmospheric pressure (between 150 and 350 PSI maximum).
If left unused for a long period of time :
Check the pressure gauge before starting up the heat pump. It must indicate at least 80 PSI.
If the pressure goes down too much, the heat pump will display an error message and automatically go into
‘safe’ mode.
This means that there has been a leakage of refrigerant and that you must call a qualied technician to
replace it.
21
6. Maintenance and servicing
6.1 Maintenance, servicing and winter storage
WARNING: Before undertaking maintenance work on the unit, ensure that you have

The following operations must be undertaken by a qualied person at least once a year.
✔ Carry out safety checks.
✔ Check the integrity of the electrical wiring.
✔ Check the earthing connections.
✔ Monitor the state of the pressure gauge and the presence of refrigerant.
Winter storage
Your heat pump is designed to operate in rainy weather conditions and withstand frost using a specially
created anti-frost technology. However it is not recommended to leave it outside for long periods of time (eg
over winter). After draining down the pool for the winter, store the heat pump in a dry place.
22
7. Repairs
WARNING: Under normal conditions, a suitable heat pump can heat the water in a swimming
pool by 1°C to 2°C per day. It is therefore quite normal to not feel any temperature difference in
