During installation of the piping system into the wall, note the following things:
The pipe must be pre-assembled as described in2.5.9, completely and tightly
The ventilator with heat exchanger installation unit is not used in the piping
The opening in the wall is free of dust and debris
Step 6
Slide the pre-assembled pipe into the opening. There should a little slope of the piping
to the
outside
(about 2%) to ensure the further condensation drainage.
Observe the mounting direction. The screws must face
the front side.
.
Ensure the placement of the outside carriage bolts (fastening the outer cover) is
horizontal. Vertical and horizontal mounting of the outer cover is dependent
thereon.
