Guidelines
Water chemistry
Special attention should be paid to the chemical balance of the pool water. The values
should always stay within the following limits:
Min
Max
pH
7,0
7,4
Free chlorine (mg/l)
0,5
1,2
TAC (mg/l)
80
120
Salt (g/l)
3
Attention!
○
Failure to keep the swimming pool water between above limits will invalidate the
warranty
○
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 tubing, 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.
Winter-ready
Attention!
Failure to winterize could cause damage to the heat pump and will void 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: close valves 2 and 3 on the by-pass completely.
3. Disconnect the water inlet and outlet and let the water drain from the heat pump. Blow
all water out of the heat pump.
4. Re-connect the water inlet and outlet loosely to prevent debris entering the connections.
