12.1 - Dampers hoods

Depending on the assembly chosen, the fresh air and exhaust
air damper hoods are supplied folded down, to be fi tted on site
by the installer.
The elements necessary for the assembly of the hood (1) are:
■ two or three strips (depending on model) for reinforcement of
the grid panel (3).
■ two or three triangles (depending on model) for reinforcement
of the hood (4).
■ a left side closure part (5).
■ a right side closure part (6).
These elements are supplied screwed to the grid panel (2). Simply
raise the hood (1) and remove the screws that attach these ones
to the panel. These screws wil not be used for the assembly of the
hood. All the screws required for this assembly are supplied in a
bag. They are 4.8 x 19mm self-tapping hex screws.

Important: The left and right closing parts are not
interchangeable. Each one must be mounted in the
correct position in order to ensure that the hood is
perfectly closed.
■ Step 5: Finally, screw the left side (5) and right side (6) closure
parts to the hood (1) using 4 or 5 screws (depending on
assembly).

Important: Always check that the union of two panels using self-
tapping screws is properly secured. The self-tapping screws
must not be unscrewed frequently to prevent any clearance on
the threading.
Caution: the detachment of the hood due to wrong
implementation of the above steps may cause personal
injury and property damage.

12.2 - Droplet eliminator at the fresh air intake

The droplet eliminator can be installed on the fresh air intake. It
is recommended in cases where a high moisture content in the
air is foreseen.
The droplet eliminator (7) is placed after the hood:
■ First, the part (8) is placed inside the hood (1), using 4.8 self-
tapping hex screws. If the droplet eliminator has been ordered
together with the unit, this part will be installed in the factory.
■ Next, the side profi les (9) are fi tted onto the side parts of the
hood (5) and (6), each with 2 of the 4.8 self-drilling hex screws.
■ Finally, the profi le (10) is fi tted onto the panel (2). To do this,
unscrew the lower screws on the panel (M6 Allen) and screw
them back on, attaching the profi le.
