7. Installation preparation

Danger to life from electric
shock.
 Switch the mains fuse off.
DANGER
7.1 Wall, ceiling or bracket
i
Notes
● Any installation position. IP X4 only when
installed in ducts with at least 1 m of duct
on the suction and pressure sides.
● Only install on walls, ceilings or brackets
with sufficient load-bearing capacity.
Danger of injury from failure
to mount ventilation box
securely.
WARNING
 Make sure you use mounting
material, which is sized for the
purpose.
 Decide on the installation location. Make
sure there is sufficient distance to the
wall/ceiling so that the housing cover and
the fan unit can also be removed.
 Lay a permanent power cable to the
installation location.
7.2 Preparing the ventilation ducts
i
Notes
● Only use folded spiral-seams ducts that
match the nominal diameter. Ø 125,
Ø 160, Ø 200, Ø 250, Ø 315, Ø 355 or
Ø 400 ducts are permitted, depending on
unit type.
● Install an air filter in the ventilation duct,
e.g. Maico TFE if operating the unit in a
dusty environment.
8. Installation
8.1 Fitting ventilation box
As far as possible, install the
i
ventilation box such that there is no
transfer of vibrations to the duct
system, e.g. by using Maico EL
flexible cuffs and vibration dampers.
 Make sure there is a level surface at the
installation location.
 Mark the position of the 4 mounting holes
and make the holes.
 For suspended duct systems, fit a
mounting support with sufficient load-
bearing capacity.
 Screw the ventilation box permanently to
the wall, ceiling, bracket or mounting
support using suitable mounting material
to be supplied by the customer.
Note air direction arrow on the
i
rating plate.
 Fit permitted folded spiral-seams ducts and
secure with flexible cuffs
8.2

Electrical connection

Danger to life from electric
shock.
 Switch the mains fuse off.
DANGER
 Position a warning notice to
avoid the unit being acciden-
tally switched back on.
The cabling between the power and
i
the terminal [3] box must be
permanent.
Voltage controllable fans are
i
allowed to be used in continuous
operation with a minimum of half
of the nominal voltage. If this is
not complied with, it can cause
damage to the motor unit.
