In order to prevent icing-up, it may be necessary to supply the condense outlet inside the
building envelope with a heating cable. It is the installation contractor’s responsibility to
frost protect the condense outlet.
The hot-water tank is enamelled inside and equipped with a magnesium sacrificial anode.
All branches have a ¾” thread socket.
All water connections are connected in the bottom and must be done with flexible pipes.
Hot-water circulation can be established if required, by mounting a check valve on the circulation
branch of the tank.
The branch should remain shut if there is not established hot-water circulation.
There can be a significant heat-loss in the pipes due to the hot-water circulation which reduces the
output of the heat pump considerably. To avoid this it is necessary to insulate the circulation pipe
and the hot-water circuit with at least 30mm mineral wool or pipe insulation.
