Air return
Figure 87: Mounting of the air return
1. Remove the pre-punched pipe lead-through in the protection grid of the
air outlet (e.g. with a small side cutter).
2. Pass the air return through the opened feed-through in the protection
grid and fix it with the existing pipe collar in the air outlet of device. As
the air return pipe fits exactly into the exit air opening, a tight fit is en-
sured.
NOTICE
Wide temperatures variations make it necessary to fix the air return pipe
tightly just in front of the device so that the pipe is not pulled from the pipe
connection due to linear expansion (see chapter „Linear expansion of the
pipe system“) .
