12.2.3 Routing air hoses
Note
In the case of heat pumps installed indoors, if a blow-
er door test to EN13829 is to be carried out, then all
apertures which are purposely provided in the building
envelope must be closed or sealed off before the air hoses
are installed.
For the blower door test, seal off the heat pump
supply air and extract air ducts.
Note
Air hoses guide the intake air to the appliance and route
the discharge air from the appliance outdoors. They are
highly flexible, thermally insulated and self-extinguishing
in case of fire.
General information
The air hose can be extended by turning the hose spirals into
each other. There must be an overlap of approx.30 cm. The total
length of hoses on the air intake and discharge sides must not
exceed 8m.
Never incorporate more than four 90° bends. The radius of
the bends must be at least 600mm, relative to the centre of
the hose.
Cut to size using a sharp knife. The hose spirals can be cut
with wire cutters.
Secure the air hose at intervals of approx. every1m to pre-
vent it from sagging.
Manipulate the ends of the air hoses to fit the oval shape of
the connectors on the cover and the hose connection panels
or wall outlets.
