3. INSTALLATION
3.8 Operation
Use condions
For the heat pump to operate normally, the ambient air temperature must be between - 10 °C and
43 °C when it is used alone, or between - 20 °C and 10 °C when used with the SPA heater.
In order to be heated, the water must circulate in the heat pump. The heat pump will not start if
the water is not circulang.
Advance noce
Prior to starng the heat pump, please:
• Check that the equipment is in a stable posion.
• Check that your electrical installaon is in good working condion.
•
Check that the hydraulic connecons are properly ghtened and there is no water leakage.
• Remove any object that is not required around the equipment and all tools.
Operaon
1. Connect the power supply to the device.
2. Start the ltraon pump.
3. Acvate the device’s electrical supply protecon (dierenal switch situated on the
power cable).
4. Start the heat pump.
5. Select the desired temperature using one of the modes appearing on the control panel.
6. The heat pump’s compressor will start shortly aer.
7. Let the heat pump and the water pump run 24 hours a day unl the desired water tempe-
rature is reached. The heat pump will then stop working. The heat pump will then restart
automacally (as long as the water pump is running) as soon as the water temperature in
the pool is one degree lower than the set temperature.
WARNING: Under normal condions, a suitable heat pump can heat up the tub water by 1 °C
to 2°C per hour. It is therefore normal that you do not feel any dierence in temperature at the
outlet level when the heat pump is on.
Good to know: restart after power failure
Aer a power failure or a usual interrupon, turn the power back on. The system is in sleep
mode. Restart the dierenal plus and switch on the heat pump.
A heated tub must be covered and
insulated to avoid any heat loss.
