3.1 Setting up and assembling
The assembly and set-up contains loose parts, which are described in the
section
“Extent of delivery”
. The loose parts have been placed in the first fan section.
Outdoor air
handling units
It is important that the roof is fitted on the air handling unit at the same time it is set up.
This is to prevent water entering the air handling unit.
3.1.1 Installation site requirements
There must be free space in front of the air handling unit along the whole length to
ensure easy access for inspection, cleaning and servicing.
The doors must be able to be opened to their entire width, for inspection and cleaning,
in some cases this is 1200 mm. In connection with servicing, it is recommended that the
service area is as wide as the air handling unit, since all of the components can thus be
easily taken out.
Outdoor air
handling units
Air handling units installed on roofs may not be incorporated as part of the roof cover of
the building. The air handling units must have a complete roof deck under them.
All vertical and horizontal joints between the individual sections must be
carefully sealed with a suitable sealant that is weather-resistant, e.g.
construction silicone. Carefully degrease all of the surfaces before applying
the sealant.
Important: When installing outside, the damper motor and motor valves must be
protected against penetrating water and frost.
