4.4 Water chemistry

Special care should be taken to keep the chemical balance of your swimming pool within following
limits:
pH
Free chlorine (mg/l)
TAC (mg/l)
TAC (°F)
Salt (g/l)
Attention: failure to keep the swimming pool water between above limits will void
the warranty
Attention: 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 auto-
matic chemical feeder is installed in the plumbing, it must be installe down-
stream 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.

4.5 Winterizing

Although our Sun Spring 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:
• Turn off the electrical power to the heat pump at the main breaker panel.
• Shut off the water supply to the heat pump.
• Disconnect the water inlet and outlet and let the water drain from the heat pump.
• Re-connect the water inlet and outlet loosely to prevent debris entering the connections.
Attention: failure to winterize could cause damage to the heat pump and will void warranty

4.6 Spring startup

If your heat pump has been winterized, perform the following steps when starting the system in the
spring:
• Inspect the system for any debris or structural problems.
• Connect the water inlet and outlet unions firmly.
• Turn on the filter pump to supply water to the heat pump.
• Restore electrical power to the heat pump and switch it ON.
The heat pump is not capable of
transferring all the heat it has ge-
nerated.
The unit is indicating that the
ambient air temperature is high
enough to operate without its fan.
The fan is being switched off.
Insufficient water flow. The fan
has stopped but the compressor
is still running.
Check/restore the water flow. The
heat pump will start after 3 minu-
tes delay when the flow is the unit
is sufficient again.
