General
!
It is very important that
the branch pipes are
exactly the same length
when they go into the
collection pipe.
!
When the lower cooling
module is connected on
the side, the rim must
be insulated with the
rubber strip to prevent
it rubbing against the
hose.

4.1 Connection
Connection can be on the right, left, top and rear of the heat pump. Cut
away the cover plate on the side where the hoses are to be connected.
When a hole has been made in the side plate, carry out the installation as
follows:
1. Place the protective edging provided around the edge of the hole in the
insulation plate in order to protect the hoses. If necessary, adjust the
length of the edging so that it fits in the hole.
2. Pass the hoses through the hole in the side cover plate and connect
them. Ensure that the insulation covers all parts of the brine connection
to prevent ice and condensation forming.
3. Then install the collector system.
It is also possible to connect the flow on one side and the return on the
other. See Measurement information for measurements and dimensions. The
dimension of the pipe between the heat pump and brine loop must not be
less than Ø35 mm.

4.1.1 Heating medium side
The heat pump is connected with at least Ø35 mm and can then be taken
into a collection pipe. The check valve and dirt filter are 1¼". The collection
pipe is dimensioned according to the installation in question.
Route the pipes so that there is no other highest point where air can
accumulate and prevent circulation. If this is unavoidable, provide this
highest point with an automatic bleeder.
