6.1 Swimming pool water chemistry
Special attention should be paid to the chemical balance of the pool water. The pool water values should
always stay within the following limits:
Min
Max
pH
7.0
7.4
Free chlorine(mg/1)
0.5
1.2
TAC (mg/1)
80
120
Salt(g/1)

Important: failure to comply with these limits will invalidate the warranty
Note: Exceeding one or several limits can damage the heat pump beyond repair. Always install water
treatment equipment past the heat pump’s water outlet, especially if the chemicals are automatically
added to the water.
A check-valve should also be installed between the outlet of the heat pump and this equipment in
order to prevent products from flowing back into the heat pump if the filter pump stops.
6.2 Heat pump winterizing
Important: Failure to take the necessary precautions for winterizing can damage the heat pump, which
will invalidate the warranty.
The heat pump, filter pump, filter and conduits must be protected in areas where the temperature can drop
below the freezing point, evacuate all water from the heat pump as follows:
1. Interrupt the electrical power supply to the heat pump
2. Close the water supply to the heat pump, completely close valves 2 and 3 of the by-pass
3. Disconnect the water inlet and outlet coupler fittings of the heat pump and let the water drain out
of the unit
4. Loosely reattach the water inlet and outlet coupler fittings to the heat pump in order to prevent
dirt from settling into the conduits.
Note: These precautions should not be taken if you choose to use the built-in anti-frost
6.3 Restarting the pump after winter
If you purged your heat pump for winterizing, you should undertake the following steps to restart it in spring:
1. Check first if there is no dirt in the conduits and if there are no structural problems
2. Check if the water inlet and outlet coupler fittings are adequately fastened to the heat pump
3. Start the filter pump to start the water flow to the heat pump. Set the by-pass again
4. Reconnect the electrical power supply to the heat pump and turn it ON
6.4 Check-up
Our heat pumps have been developed and built to last, that is, if they have been installed correctly and can
run under normal conditions. Regular maintenance is important if you want your heat pump to function
safely and efficiently for years on end.
1. Make for easy access to the service panel
2. Keep the area surrounding the heat pump free of contingent organic waste
3. Prune the vegetation near the heat pump so that there is enough free space around the pump
4. Remove contingent water sprinklers from the vicinity of the heat pump. They can damage the heat
pump
5.Prevent rain from directly running off a roof onto the heat pump. Install proper drainage
