We recommend the mechanical ventilation system
is checked for the following characteristics:
■
Clear cross-section of outdoor air intake and exhaust
air discharge.
■
Sizing and routing of ducts according to design.
■
Correct appliance siting and fitting of ducts, silenc-
ers, air distribution boxes, supply and extract air
vents.
■
Correct condensate draining, correct thermal insula-
tion of ducts in cold areas.
Note
The ductwork may be cleaned via the supply air and
extract air vents.
Starting the ventilation unit
!
Please note
Dust entering the ventilation unit and the duct-
work can result in faulty operation of the
mechanical ventilation system.
Only start the ventilation unit after all other con-
struction work inside the building has been com-
pleted.
!
Please note
Operating the ventilation unit with closed supply
air and extract air vents will result in appliance
damage.
If supply air and extract air vents were sealed off
with adhesive film during construction work,
remove that film completely
prior
to starting the
ventilation unit.
Insert the mains plug of the ventilation unit into a
standard socket with separate fuse/MCB protection
(230 V/50 Hz).
