10. Recommendations
Important: failure to comply with these recommendations will invalidate the warranty
Note: non-compliance with one or more of these recommendations 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.
11. Heat pump winterizing
Important: failure to take necessary precautions for winterising 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 freezing point. Evacuate all water from the heat pumps as follows:
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. (if necessary, tilt the heat pump
until all water has been drained from the heat exchanger). Damage caused to the heat
exchanger due to freezing will not be covered by the warranty.
4. Loosely re-attach water inlet and outlet coupling fittings of the heat pump in order to prevent
dirt from getting into the conduits.
