7. Installation preparations
Wall, ceiling or bracket
Notes
●
Any installation position. IP 44 degree of
protection 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.
WARNING
Danger of injury from failure
to mount ventilation box
securely!
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.
For system operation, route a permanent
power cable to the ECR supply air box.
Preparing the ventilation ducts
Notes
●
Folded spiral-seams ducts with a Ø 125,
Ø 160, Ø 200 or Ø 250 diameter are
permitted, depending on the fan type.
●
Only use folded spiral-seams ducts that
match the nominal diameter.
●
Connect the ventilation ducts to the
ventilation box using flexible cuffs, e.g.
Maico EL.., in order to prevent the
transmission of vibrations to the duct
system.
●
Install an air filter in the ventilation duct,
e.g. MAICO TFE.. if operating the unit in a
dusty environment.
8. Assembly
Installation
As far as possible, install the
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 rating
plate.
