2.1 I Operating principle

The heat pump uses the calories (heat) in the air to heat up your pool's water. The process to heat your pool's water to
the temperature you want may take a few days as it depends on the weather conditions, the heat pump's power and the
difference between the water temperature and the temperature you want.
The hotter and more humid the air, the better your heat pump will perform. The outdoor parameters for optimal
operation are an air temperature of 28°C, a water temperature of 28°C and 80% relative humidity.
Tip: to improve the heating and maintaining of your pool's temperature
• Anticipate the commissioning of your pool far enough in advance before you use it.
• When the temperature of the pool is increasing at the beginning of a season to reach the desired
temperature, set the water circulation to continuous operation (24/7).
• To maintain the temperature throughout the season, run "automatic" circulation for the equivalent of the
water temperature divided by two (the longer this time, the more sufficient the operating range of the
heat pump to heat the pool).
• Cover the pool with a sheet (bubble canopy, canvas, etc.) to prevent heat loss.
• Take advantage of a period with mild outdoor temperatures (on average > 10°C at night); it will be even
more effective if it runs during the warmest hours of the day.
• Keep the evaporator clean.
• Set the temperature you want and let the heat pump run.
• Connect the "Heating priority"; the filtration pump and heat pump operating time will be set according
to requirements.
2.1.1 Precautions
• Certain precautions must be taken to avoid damaging the condenser (for the precautions
specific to winterising, refer to § 3.1).
• If the heat pump is subjected to extended exposure to negative outdoor temperatures
(excluding winterising period), you must:
- Activate the ''Heating Priority'' option: the filtration pump will operate while the pool's
temperature is below the heat pump's setpoint temperature. If the setpoint is reached, the
pump will operate for 5 minutes every 120 minutes by default.
- Make sure that the pool's filtration pump is activated at least every 4 hours if the ''Heating
Priority'' option is not activated on the heat pump.
