2.1 I Operating principle

2.1.1 General operation
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 conditions, your heat pump's power and
the difference between the water temperature and the temperature you want.
The warmer and damper the air, the better your heat pump will perform. The outdoor parameters for optimum operation
are an air temperature of 27°C, a water temperature of 27°C and 80% relative humidity.
Tip: improve your pool's temperature rise and maintenance
• Anticipate the commissioning of your pool far enough in advance before you use it.
• For the temperature rise, set the water circulation to continuous operation (24/24).
• To maintain the temperature throughout the season, run "automatic" circulation for at least 12 hours/
day (the longer this time the longer the heat pump will have enough operating range to heat up).
• Cover the pool with a sheet (bubble canopy, canvas, etc.) to prevent heat loss.
• The heat pump will be even more efficient if it operates during the warmest hours of the day.
• Keep the evaporator clean.
• Set the temperature you want and let the heat pump run (adjusting the setpoint to maximum will not
heat the water more quickly).
• Connect the "Heating priority"; the filtration pump and heat pump operating time will be set according
to requirements.
