1. Switch on the fi lter pump. Check for leaks and verify that water is fl owing from and to the
swimming pool.
2. Press the On/Off button on the control unit panel to activate it, the display shows the water
inlet and outlet temperatures. The unit will start up after the time delay expires (see " Time
Delay" section).
3. After a few minutes, check whether the air blowing out of the heat pump fan is cooler.
4. When the fi lter pump is turned off, the heat pump should also turn off automatically, if not, then
adjust the fl ow switch (performed by specialist technician only).
5. Allow the heat pump and the fi lter pump to run 24 hours a day until the desired water
temperature is reached. The heat pump will stop running at this point. After this, it will restart
automatically (as long as the fi lter pump is running) whenever the swimming pool water
temperature drops 2 degrees below the set temperature.
6. To set the water temperature and program the heat pump, see "Display Control Panel
Operation " section for details.
Depending on the initial temperature of the pool water and the ambient air temperature, it may
take several days to heat the pool water to the desired temperature. A good solar pool cover can
reduce the heating time.
Time Delay
The heat pump has a built-in 1 to 2-minute start-up delay to protect the control circuit components
and avoid excessive restart cycles. The unit will restart automatically after this time delay expires.
Even a brief power interruption will trigger this time delay and prevent the unit from restarting
immediately. Additional power interruptions during this delay period do not affect the 1 to 2-minute
duration of the delay.
Water Flow Switch
The heat pump is equipped with a fl ow switch to protect it from running without adequate water
fl ow rate. It will turn on when the pump runs and shut it off when the pump shuts off. If the pool
water level is higher than 1m above or below the heat pump's automatic fl ow switch adjustment
knob, your specialist technician may need to adjust the initial startup water fl ow rate.
