Inserting flexible pipes into the flexible pipe connection
►
Insert the flexible pipes into the openings
in the flexible pipe connection on the wall
box and seal the join with a layer of seal-
ing tape 30 mm wide (item 1 in Fig. 18) or
insert sealing rings. These are available as
accessories M-WRG-FR-DR75 or M-WRG-
FR-DR63 for the corresponding nominal
diameter.
►
Insert the flexible pipe connection into the
fixing plate.
NOTE
►
Run the flexible pipes without forcing or
stresses.
►
Fix the flexible pipes in place with expand-
ing foam. This will improve both the seal
and the insulation.
