ASSEMBLY OF SECTIONS
If the Air Treatment Unit is broken down into two or
more sections. proceed as follows:
- Check the module assembly order on the TCF
working drawing.
- Remove the material required for assembly, supplied
on delivery, from the container located inside one of
the inspection doors.
- Clean the steel sections at the point of connection of
the modules and tit the SELF—ADHESIVE SEALING
STRIP provided (fig. 7).
The same strip must also be fitted to the duct
connection flanges.
- Set the individual sections set by side, using a SPIRIT
LEVEL to check that the assembled parts are perfectly
aligned and level. (fig. 8)
- Fasten the sections together with screws in the holes
provided.
The holes are located on the inside of the corners and,
in the case of dimensions greater than 1.3 m, also in a
midway position.
The screw-fastening areas can usually be accessed
from the inspection doors. Otherwise, you must
remove the panels next to the area involved.
Should the Unit be installed outdoors, in addition to the
steps listed above, the points of connection of the
individual modules must also be sealed with
waterproofing silicone (fig. 9).
Special care must be taken with the roofing to afford
protection against the elements: the two edges will be
jointed by means of a bayonet system, assisted by
silicone treatment or a specific seal (fig. 10).
