4.1 Positioning of the unit

Before installing the unit, make sure that the
structure of the building and/or the supporting
surface can withstand the weight of the
appliance. The weights of the units are listed in
DANGER
Chapter 8 of this manual.
These units have been designed for outdoor installation on a solid
surface. Standard accessories include antivibrating rubber supports,
that must be positioned under the base.
When the unit is to be installed on the ground, it is necessary to
provide a concrete base, to ensure a uniform distribution of the
weights.
As a general rule, no special sub-bases are required. However, if the
unit is to be installed on the top of inhabited rooms, it is advisable
to rest it on spring shock absorbers (optional), that will minimise the
transmission of any vibration to the structures.
To choose the place of installation of the unit, bear in mind that :
the longitudinal axis of the unit must be parallel to the direction of
n
prevailing winds, so as to ensure a uniform distribution of the air
on finned exchangers
the unit must not be installed near boilers' vent pipes
n
the unit must not be installed leeward with respect to sources of
n
air contaminated by greases, such as, for example, the outlets
to kitchen exhaust hoods into the atmosphere. Otherwise,
the grease is likely to deposit on the fins of the refrigerant /air
exchangers, and would fix every type of atmospheric impurity,
resulting in the quick clogging of the exchangers
the unit must not be installed in areas subject to considerable
n
snow falling
the unit must not be installed in areas subject to flooding, under
n
gutters etc.
the unit must not be installed in air shafts, narrow courts or other
n
small places, where the noise may be reflected by the walls or
the air ejected by fans may short-circuit itself on refrigerant/air
heat exchangers or condenser
the place of installation must be have all the necessary spaces
n
for air circulation and maintenance operations (see Chapter 8).
