Connect to the electrical terminal block
Since this damper is square, it requires a rectangular/circular adapter part for connecting to circular
ducts.

CONNECTION THE CONDENSATE EVACUATION (CHANGEOVER MODULE)
It is important to install a condensate evacuation siphon to
prevent odours, and offset the pressure difference between
the outside (atmospheric pressure) and inside of the unit.
The height X (in mm) must correspond to at least the negative
pressure in the unit (allowing a margin of 50 mm), in mm water
column. See formula opposite.
The height Y (in mm) must correspond to half the negative
pressure in the unit. We generally adopt Y=X/2 (see formula
opposite).
If the unit is installed in unheated premises or outside, the
siphon must have thermal insulation and be heated by means
of a cable (not supplied by France AIR)
If a siphon is not installed, the machine warranty is no longer
valid.
WARNING
To prevent freezing risks, the fluid circulating on these coils must be able to withstand the negative
temperatures generally encountered in the region where the machine is to be based.
4.6.
INSTALLING THE ROOF (MANDATORY FOR OUTDOOR INSTALLATIONS)
The roof comprises a symmetric sheet with prepared folds and two end parts. The roof also comes
from the factory with pre-drilled mounting holes. The sheets must be mounted using screws (supplied)
and sealing caps (supplied) placed on each hole in the sheet.
WARNING
Since the roof is delivered as an accessory, the ventilation unit profile and modules are not drilled.
First, you need to place & centre the roofs, and drill the profiles, using the pilot holes present as a
guide. Sealing accessories (supplied) are used with each screw.
If a module is coupled to the ventilation unit, the roofs are joined by means of a plastic seal.
