6. Operation and controls
Operational instructions
IMPORTANT:
❑
Pool heating by the heat pump requires the operation of the filtration pump and water flow through the heat
exchanger.
❑
Never switch the heat pump on if it contains no water and if the filtration equipment is not working.
❑
Do not cover the heat pump; ambient air must flow during operation.
❑
Protect the heat pump from freezing. Discharge water from the filtration and heat pump and ensure winter
preparation according to the manual before the first frost.
Water condensation
Lower evaporator temperatures during heat pump operation causes air humidity condensation on the evaporator blades and
formation of condensate or icing. If the relative air humidity is very high, several litres of water may condensate in one hour. The
water flows from the blades to the bottom of the cabinet and then out through its base.
It is very easy to mistake condensed water for water leakage from inside the heat pump. There are two simple methods to check
whether it is condensation or not:
1. Switch the equipment off and only leave the pool pump running. If the water stops flowing, it is condensed water.
2. Perform a test for chlorine presence in the flowing water (if chlorine is used for pool disinfection)
– if the flowing water
doesn’t contain chlorine, it is condensation.
Note: Eventual ambient humidity is caused by the condensation of water vapours and is not a problem.
Possible issues caused by external conditions
Under certain external conditions the exchange of heat between the coolant and water on one side, and between the coolant and
air on the other, may be insufficient. This can lead to increased pressure in the coolant circuit and increased compressor power
consumption.
The heat pump is fitted with pressure and temperature sensors, which will prevent incorrect operation under extreme conditions.
The cause may be insufficient water flow. To increase the heat exchange

water , close the by-pass valve (if installed) to
increase the flow of water through the exchanger.
Notes on heat pump operation
❑ The efficiency of the heat pump increases with the rising temperature of ambient air.
❑
Several days may be required to reach the required temperature. This time is normal and particularly depends on the
climatic conditions, volume of pool water, water surface area, heat pump operation time and thermal loss from the pool
(e.g. surface evaporation, heat permeation, radiation, etc.). In case no adequate measures are taken to reduce heat loss,
high water temperature maintenance is not economical, and in some cases not possible.
❑ To reduce heat loss when the pool is not in use, apply a cover or solar tarpaulin.
❑ The wa ter temperature in the pool should not exceed 30°C. Warm water is not very refreshing and also creates optimal
conditions for algae growth. Certain pool components may also have temperature limitations. For example, foil pool foils
may become softer. There
fore do not set the thermostat to more than 30°C.
