FRESH AIR INTAKE
There is a cut-out on the side of the unit,
which can be used as a fresh air intake. It
can be opened with a screwdriver.
DUCTING
Important: the ducting must be
designed and calculated by qualified
technicians.
Determine the dimensions of the ducts
according to the air flow rate required and
the available static pressure of the unit
(refer to the fan diagrams on previous
pages).
You are advised to adhere to the following
recommendations:
• regardless of the type of duct used, it
must not be made of inflammable material,
which produces toxic gases in the event of
fire. The internal surfaces must be smooth
and not contaminate the air passing
through them. You are advised to use
ducts in galvanised steel, suitably
insulated, to prevent the formation of
condensate and thermal losses.
• The ducts should be joined with flexible
couplings which absorb vibrations, prevent
noise transmission inside the ducting and
allow access to the unit.
• As far as possible, avoid bends near the
unit’s air outlet. If this is not possible, the
radius of curvature must be as wide as
possible; use internal deflectors if the duct
is of large dimensions.
