Connection of Condensate Discharge
The extraction of heat from the air causes the condensation of air humidity in the heat pump.
Depending on the season and hot water requirements, between 1 and 5 litres of condensate per day
accumulate. This condensing water can be used for steam ironing or watering. A discharge tube is
fitted at the back of the device to drain the condensate. If free drainage of the condensation is not
possible, a collecting vessel of at least 10 litres must be provided.
Caution: when connecting condensate outlet care must be taken that the tube is always turned
downwards. If longer tubes are used, a return valve must be fitted at the bottom of the outlet tube to
ensure proper drainage of the condensate and to avoid the discharge odour to spread.
