Special care should be taken to keep the chemical balance of your swimming pool within following
limits:
Min.
Max.
pH
7,0
7,8
Free chlorine (mg/l)
0,5

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
CAUTION!
Failure to winterize could cause damage to the heat pump and will void warranty.
Although our Xpress heat pumps are protected against freezing, it is good practice to drain the
complete installation. Perform the following actions 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.
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.
