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.
