INSTALLING THE UNIT
Important: the unit must be correctly
levelled.
Insert the 4 M8 threaded tie rods into the
ceiling. Insert the other end of the tie rods
through the slots in the hanging brackets
on the sides of the unit. Position the anti-
vibration dampers, add the washers and
tighten the nuts until the unit is correctly
fixed and levelled. If space permits, place a
layer of rubber or neoprene between the
ceiling and the unit.
On completion of these operations it is
necessary to:
• install a suspended ceiling to conceal the
unit;
• include a removable panel for future
maintenance work;
• fit suitably sized grilles in the suspended
ceiling to allow air intake.
CONDENSATE DRAINAGE
Important: do not lift the unit by means
of the condensate drain pipe.
All units are equipped with a condensate
collection tray with 21 mm external Ø drain
pipe.
Therefore fit a pipe for the evacuation of
condensate.
Adhere to the following recommendations:
• Use pipes in galvanised steel, copper or
transparent plastic. Do not use normal
garden hoses.
• Use material which ensures that the
drain pipe connections are totally sealed.
• If using rigid material for the outlet pipe, fit
a number of flexible couplings to absorb any
vibrations from the unit.
• The drainage line must always be below
the connection itself, with a suitable
gradient to facilitate outflow.
• Pour a few litres of water into the
condensate collection tray and check that it
flows out correctly. If not, check the
gradient of the pipes and look for possible
obstructions.
INTAKE CONFIGURATION
Important: units configured for intake
from below must not be installed at a
height of less than 2.5 m from the
ground.
The unit is factory-configured for air intake
from the rear.
