POSITIONING
GENERAL
For installing air-conditioning systems, it is necessary to
consider the following:
•
the technical spaces necessary for the machine and
system
•
the place where the machine will be installed
•
the transport of thermal carrier fluids and relevant
connections to the unit:
o
water
o
air
o
refrigerant (unit in more sections)
•
electrical connections
If these aspects are not evaluated carefully, they can
affect the performances and the working life of the unit.
FUNCTIONAL CLEARANCES
When placing the unit, please respect the functional
clearances indicated in DIMENSIONS section.
The functional spaces need to be observed because of the
following:
•
to guarantee the good operation of the unit
•
to allow the performance of all maintenance
operations
•
to protect the authorized operators and exposed
people
If more units are placed close to one another, the
functional spaces must be doubled.
POSITIONING
1.
The units are designed for
INDOOR
installations,
performed in fixed positions and in areas accessible
only to qualified and authorized personnel
2.
SAFETY VALVE
(only if present on the unit) : the
installer is responsible for evaluating the opportunity
of installing drain tubes, in conformity with the local
regulations in force ( EN 378 )

Install the unit
raised
from the ground
4.
avoid installations in places subject to
flooding
5.
Verify that the fixing/supporting points are level and
suitable to support the
weight of the unit
(see the
weight and the weights distribution)
6.
to avoid noise and vibrations place a layer of rubber
between the base of the unit and the floor/support
