INSTALLATION

INSTALLATION:
The heat pump is delivered adjusted and ready assembled with wire and plug. Just connect the water inlet and outlet
to the piping and the plug to a socket. The defrost water from the evaporator is conducted from a pipe branch (13).
The dimensioned sketch shows the connections and dimensions.

MOUNTING:

Wherever possible, the heat pump should be installed close to the existing hot-water conduit. By so doing the heat
loss will be kept at low level. The place of installation must be level. Small irregularities can be levelled by means of
the adjustable feet. When filled the heat pump weighs approx. 430 kg. The place of installation must stand a
corresponding load.
NOTE: At the same time complementary rules in the building regulations must be observed.
If the heating coil or circulation pipe is not used, the pipes must be closed and isolated to avoid heat loss.
The air can be taken from the room in which the heat pump is placed, or from the basement, from the next room, or
from outside. In these cases the heat pump can be equipped with pipes, both at the air inlet and at the air outlet. The
air inlet is always located at the top of the heat pump, whereas the air outlet can be located either at the top or on the
right side of the heat pump. The pipe connections are intended for ø160mm.

WATER

INSTALLATION OF WATER:

Installations of water should be carried out in accordance with the present standards concerning installation of
water.

WATER CONNECTIONS:

The heat pump is mounted as a pressure tank intended for more outlets. In accordance with the present rules the cold-
water connection should be provided with drain valve, safety valve and adjustable retaining valve. The valves are not
standard equipment. In order to avoid noise in the piping system it is to be recommended to use approved hose
couplings when connecting the heat pump. As to the hot water connection there are several possibilities. The heat
pump can be installed both in new systems as well as together with existing systems either by disconnecting the old
heat source completely or by connecting or disconnecting it at option by means of retaining valves. During the water
filling process it might be necessary to evacuate the tank at the same time in order to get it filled. The heat pump
should only be started when you are quite sure that the tank is filled with water. The heating time to a water
temperature of 45-55°C is at first-time filling or after emptying of the tank between 8 and 10 hours at an ambient
temperature of 15°C.

ISOLATING THE CONNECTIONS:

All pipes must be isolated to prevent heat loss. Also the circulation connection and the heat exchanger connection
must be isolated. If the heat exchanger is not necessary it must be blinded.
