INSTALLATION
4.1 Positioning of the unit
Before installing the unit, make sure that the
structure of the building and/or the support-
ing surface can withstand the weight of the
appliance. The weights of the units are list-
ed in Chapter 8 of this manual.
These units have been designed for outdoor installa-
tion on a solid surface. Standard accessories include
antivibrating rubber supports, that must be posi-
tioned 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 in-
habited rooms, it is advisable to rest it on spring
shock absorbers (optional), that will minimise the
transmission of any vibration to the structures.
The spring shock absorbers are fastened to
suitable brackets (see the installation notes,
paragraph 4.2), protruding from the base
of the unit.
The use of shock absorbers provided by the
customer requires the adoption of suitable
fastening brackets (that are an optional).
To choose the place of installation of the unit, bear in
mind that:
h
the longitudinal axis of the unit must be parallel to
the direction of prevailing winds, so as to ensure a
uniform distribution of the air on finned exchang-
ers
h
the unit must not be installed near boilers’ vent
pipes
h
the unit must not be installed leeward with respect
to sources of 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 atmos-
pheric impurity, resulting in the quick clogging of
the exchangers
h
the unit must not be installed in areas subject to
considerable snow falling
h
the unit must not be installed in areas subject to
flooding, under gutters etc.
h
the unit must not be installed in air shafts, narrow
courts or other 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 ex-
changers or condenser
h
the place of installation must be have all the neces-
sary spaces for air circulation and maintenance
operations (see Chapter 9).
4.2 Spring Isolator Installation

1) proceed with the assembly of the jack components
(B-C-D-E-)
– insert the rod of the jack (B) into the threaded hole
on the upper plate of the antivibrating device (A)
– insert the support, complete with jack, into the hole
prepared on the bracket
– position the bracket and the relevant jack on the
base of the machine to be insulated, using the
holes drilled for fastening.
