ECO+ series swimming pool heat pumps
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)
TAC (°F)
80
10
150
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.
4.3 Spring startup
If your heat pump has been winterized, perform the following steps when starting the system in the
spring:
1.
Inspect the system for any debris or structural problems.
2.
Connect the water inlet and outlet unions firmly.
3.
Turn on the filter pump to supply water to the heat pump.
4.
Restore electrical power to the heat pump and switch it ON.
