4.4.3 Additional assembly steps for out-
door units
Connecting the roof segments
Air handling units for outdoor installation require the fol-
lowing additional assembly steps:
Fig. 20: Joining roof segments
①
Roof segments
②
Self-adhesive joint sealing tape
③
Cover strips
④
Self-drilling screws with sealing washers
1.
Seal all joints between the roof segments
( Fig. 20 /1) with self-adhesive joint sealing tape
( Fig. 20 /2). Follow the tape manufacturer's
instructions for use. Attach the cover strips
( Fig. 20 /3) and fix them with self-drilling screws
NOTICE!
Remove the eye nuts where the casing units
are to be joined such that you can actually join
the roof segments. Do not remove the other
eye nuts; they have to remain in place to pre-
vent the ingress of rain into the unit.

2.
Seal the joints ( Fig. 21 /1) between the cover
strips with the supplied adhesive strips
(100 x 40 mm).
Make sure that all surfaces are clean, free from
grease, and dry. Clean the surfaces, if necessary.
