Chasing out channels for flexible pipe connections
—
Installation kit M-WRG-M/MB-FR75(63)/1
with exhaust air
or
supply air pipe
► Use the wall chaser to chase out
one
channel 180 mm wide and 90 mm
deep as far as the flexible pipe outlet
in the ceiling (see Fig. 8) for either the
exhaust air pipe (item 1 in Fig. 8)
or
the supply air pipe (item 2 in Fig. 8).

Installation kit M-WRG-M/MB-FR75(63)/2
with exhaust air
and
supply air pipe
► Use the wall chaser to chase out
two
channels 180 mm wide and 90 mm
deep as far as the flexible pipe outlet
in the ceiling (see Fig. 8) for the ex-
haust air pipe (item 1 in Fig. 8)
and
the
supply air pipe (item 2 in Fig. 8).
►
Check that the installation kit fits easily into
the wall breakthrough.
►
Check that the installation kit can be
pushed far enough into the wall breakthrough for the front surface of the wall box to end
flush against the solid wall and extend 15 mm beyond the plastering trim.
Fig. 9 contains a sample layout for the flexible
pipes.
NOTE
The dimensions of the channels for the flexible
pipes are:
—
180 mm wide
—
90 mm deep
NOTE
►
Observe the following recommendations
when using flexible pipes as this will avoid
unintentional pressure losses in the flexible
pipes.
— As far as possible, use flexible pipes with nominal diameter DN 75.
— Always connect two flexible pipes to the flexible pipe connection.
— Run the two flexible pipes of a flexible pipe connection in parallel to one another.
— Minimise the number of bends in the flexible pipes.
