loss, it may take several days for the water to reach the desired temperature.
Covering the pool and other measures to reduce heat loss can significantly reduce
this time.
Water flow sensor:
The water flow sensor closes when water flows through the heat pump exchan-
ger and switches off the heat pump when the water flow stops or falls below the
minimum required level.
Time delay:
The device is equipped with a switching time delay element with a set delay time
to protect the control elements in the circuit and eliminate repeated restarts and
contactor oscillations. More details in chapter 5.5.
3.10 Water condensation
Lower evaporator temperature during heat pump operation is the cause of con-
densation on the evaporator fins and the formation of condensate or icing. If the
relative humidity is very high, it may be several litres of condensed water per hour.
The water flows down the fins into the space of the cabinet bottom and flows out
through a plastic fitting, which is designed for the connection of a PVC hose, throu-
gh which the condensate can be drained to a suitable drain.
It is very easy to confuse condensed water with water leaking from inside the heat
pump. There are two easy ways to find if it's condensate or not:
1. Switch off the device and run only the pool pump. If the water stops
flowing, it is condensed water.
2. Perform a test for the presence of chlorine in the effluent (if the pool is
being treated) - if chlorine is not present in the effluent, then it is con-
densate.
Note: Any humidity around the device is caused by the condensation of water vapour
and is completely OK.
Note: Frost on the evaporator fins results from unsuitable operating conditions (espe-
cially low ambient air temperatures in combination with higher humidity). Turn off the
machine and wait for operating conditions to improve.
