11.2 Routing air hoses
Note
In the case of heat pumps installed indoors, if a blower
door test to EN 13829 is to be carried out, then all aper-
tures which are purposely provided in the building en-
velope must be closed or sealed off before the air hoses
are installed.
For the blower door test, seal off the heat pump’s
supply air and extract air ducts.
You can extend the air hoses by unwinding the coils. There should
be an overlap of approx. 30 cm. The total length of hoses on the
air intake and discharge side must not exceed 8 m.
Never incorporate more than four 90° bends. The radius of the
bends must be at least 600 mm (relative to the centre line of the
hose).
Cut to size using a sharp knife. The Bowden core can be cut
with wire cutters.
Secure the air hose at approx. 1 m intervals. This prevents
the hose from sagging because of its flexibility.
Match the air hose ends to the shape of the oval connectors
on the cover and the hose connection plates. The hose con-
nection plates are available as accessories.
