4. Direction
4.1 Swimming pool water chemistry
pH
Free chlorine(mg/1)
TAC(mg/1)
Salt(g/1)
Important: failure to comply with these limits will invalidate the warranty.
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
7.0
0.5
80
Max
7.4
1.2
120

4.2 Heat pump winterizing
Important: failure to take the necessary precautions for winterizing can damage the heat pump,
which will invalidate the warranty.
4.3 Restarting the pump after winter
4. Loosely reattach water inlet and outlet coupler fittings to the heat pump in order to prevent dirt
from setting into the conduits.
Note: these precautions should not be taken if you choose to use the built-in anti-frost protection.
Note: exceeding one or several limits can damage the heat pump beyond repair. Always install
water-treatment equipment (e.g. chemical dosing systems) after the water outlet of the heat
pump, especially if the chemicals are automatically added to the water (e.g. automatic
chemical dosing systems).
A check valve should also be installed between the outlet of the heat pump and the
water-treatment equipment to prevent products from flowing back into the heat pump if the
filter pump stops.
1.Disconnect the electrical power supply to the heat pump
2.Close the water supply to the heat pump completely.
3.Disconnect water inlet and outlet coupling fittings of the heat pump and let the water drain out of
the unit. Make sure all water is out of the heat pump.
The heat pump, filter pump, filter and conduits must be protected in areas where the temperature can
drop below freezing point. Evacuate all water from the heat pumps as follows:
If you emptied the heat pump for winterising, follow the steps below to restart it in spring:
1.First check that there is no dirt in the conduits and that there are no structural problems
2.Check that the water inlet and outlet fittings are adequately fastened. Check that ''water inlet'' and ''
water outlet'' are correct according to the lables on the heat pump. (Water out from the filter unit =
water inlet on heat pump)
3.Start the filter pump to start the water flow to the heat pump. Adjust the by-pass so there is enough
water through the heat pump. Normally on small filter system the by-pass can be closed, so all
circulated water goes through the heat pump.
4.Reconnect the electrical power supply to the heat pump and turn the heat pump ON.
