2.1 I Operati ng principle

Your 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 conditi ons, your heat pump's power and
the diff erence between the water temperature and the temperature you want. .
The warmer and damper the air, the bett er your heat pump will perform.
Tip: improve your pool's temperature rise and maintenance
• Anti cipate and plan the use of your pool well enough in advance before you use it.
• For the temperature rise, set the water circulati on to conti nuous operati on (24/24).
• To maintain the temperature throughout the season, run "automati c" circulati on for at least 12 hours/
day (the longer this ti me the longer the heat pump will have enough operati ng range to heat up).
• Cover the pool with a an appropriate pool cover (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 eff ecti ve 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 (adjusti ng the setpoint to maximum will not
heat the water more quickly).
