3.6 Condensation
Since the heat pump cools down the air about 8°C
– 12 °C, water may condense on the fins of the
evaporator. If the relative humidity is very high, this could be as much as several liters an hour. Sometimes
this condensation water is wrongly considered as swimming pool water.
4. Guidelines
4.1 Water chemistry
Special care should be taken to keep the chemical balance of your swimming pool within limits:
pH
7,0
– 7,4
Free chlorine (mg/l)
0,5
– 1,2
TAC (mg/l)
80
– 120
Salt (g/l)
max. 3
Important: failure to keep the swimming pool water between above limits will void the warranty.
Note
: when the concentration of one or more products mentioned above becomes too high, irrevocable
damage to your heat pump may occur. Make sure that you always install water treatment equipment after
the heat pump. When an automatic chemical feeder is installed in the plumbing, it must be installed
downstream of the heat pump. A check valve must be installed between the heat pump and the chemical
feeder to prevent back-siphoning of chemically saturated water into the heat pump where it will damage the
components.
4.2 Winterizing
Important: failure to winterize could damage the heat pump and will void the warranty
In areas where freezing temperatures occur, you should protect your pump, filter, and heat pump from the
elements. Perform the following steps to completely drain the heat pump:
1. Turn off the electrical power to the heat pump at the main breaker panel.
2. Shut off the water supply to the heat pump: completely close valve 2 and 3 on the bypass.
3. Disconnect the water inlet and outlet and let the water drain from the heat pump.
4. Re-connect the water inlet and outlet loosely to prevent debris entering the connections.
