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.
12. Restarting the pump after winter
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 running through the heat pump. Normally on a 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.
13. Check-up
Our heat pumps have been built and developed to last long if they have been installed
correctly and can operate in normal conditions. Regular check-ups are important if you want
your heat pump to function efficiently for many years. Below are some recommendations to
ensure optimal working conditions for your heat pump.
1). Make sure that the service panel is easily accessible.
2). Keep the area surrounding the heat pump free of organic waste.
3). Prune any vegetation around the heat pump so that there is sufficient free space
around the pump.
4). Remove any water sprinklers that are near the heat pump as they could cause damage
to it.
5). Prevent rain from running directly onto the heat pump from a roof. Install proper
drainage.
6). Do not use the heat pump if it has been flooded. Immediately contact a qualified
technician to inspect the heat pump and carry out necessary repair.
Condensation can occur when the heat pump is running. This condensation water can flow
away through an opening in the base pan of the unit. The amount of condensation water will
increase when humidity is high. Remove any dirt that could block the water outlet on the
