Installation
SELECTING THE INSTALLATION
POSITION
• The 40DMC unit is designed ducted instal-
lation in suspended ceilings.
• The unit must not be accessible to the pub-
lic.
• As a rule, the unit cannot be installed at a
height of less than 2.5 m.
• It is possible to install the unit at a height of
between 2.2 m and 2.5 m from the ground if
the system is configured for intake from the
rear. In this case, it is necessary to provide
an intake duct with minimum length of 250
mm.
Avoid the following:
• Positions exposed to direct sunlight.
• Areas near heat sources.
• Damp places and positions in which the
unit could come into contact with water (e.g.
laundry rooms).
• Rooms in which shelving or furniture may
obstruct the flow of air.
Do the following:
• Select a position capable of supporting the
weight of the operating unit.
• Leave sufficient space around the unit for
maintenance and free circulation of air (see
figure).
• Leave an aperture in the suspended ceil-
ing or ensure that a part of the latter can be
removed for carrying out maintenance oper-
ations on the unit.
• Select a place which is free from dirt, for-
eign bodies or other material that may
obstruct the coil.
• Suitable dampers must be placed between
the brackets of the unit and the hanging sys-
tem so as to prevent noise transmission.
• Install the unit in such a way that conden-
sate can be drained easily to a suitable
waste outlet.
Note: A drilling template has been provided
on the unit packaging to facilitate installa-
tion.
