5. Allow the heat pump and the filter 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 filter pump is running) whenever the swimming pool
water temperature drops 2 degree below the set temperature.
Depending on the initial temperature of the water in the swimming pool and the air
temperature, it may take several days to heat the water to the desired temperature. A good
swimming pool cover can dramatically reduce the required length of time.
Water Flow Switch:
It is equipped with a flow switch for protecting the HP unit running with adequate water flow r
ate .It will turn on when the pool pump runs and shut it off when the pump shuts off. If the p
ool water level higher than 1 m above or below the heat pump’s automatic adjustment kno
b, your dealer may need to adjust its initial startup.
Time delay - The heat pump has a built-in 3-minute start-up delay to protect the circuitry and
avoid excessive contact wear. 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 3-minute
duration of the delay.
3.9 Condensation
The air drawn into the heat pump is strongly cooled by the operation of the heat pump for
heating the pool water, which may cause condensation on the fins of the evaporator. The
amount of condensation may be as much as several litres per hour at high relative humidity.
This is sometimes mistakenly regarded as a water leak.
