4. Guidelines
4.1 Water chemistry
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
1,5
TAC (mg/l)
80
150
TAC (°F)
10
30
Salt (g/l)
8
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 ECO+ 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.
5. The heat pump shall always be stored in a dry and dust free environment
where temperature never falls below 5 degrees Celsius.
