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 OUTDOOR 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 )
3. Install the unit raised from the ground
4. avoid installations in places subject to flooding
5. Consider the maximum level which can be reached
by snow
6. Verify that the fixing/supporting points are level and
suitable to support the weight of the unit (see the
weight and the weights distribution)
7. To avoid the transmission of vibrations it is
recommended the positioning on neoprene stripes
Flexible joints are necessary on all the hydraulic/
aeraulic connections (the joints are not supplied by
Clivet)
8. Anchor the unit to the ground; foresee windbreak
barriers in case of places where there are strong
prevalent winds .
9. The choice of the location of the unit is of
fundamental importance for correct operation; to
avoid:
obstacles that block the flow of air
difficulty in air circulation
leaves or other objects that may block the
exchanger coils
winds that contrast or excessively assist the air
flow
phenomena of stratification or air re-circulation
nearby sources of heat (chemney, extractor ecc)
positioning under the round level or near very high
walls
The previous situations cause working anomalies or
stop the machine and cause:
during SUMMER operation, increase of the
condensation pressure with the decay of
performances and possible stops due to high
pressure.
Consider clearances and direction of expelled air.
Keep the coil clean. Avoid zones
with leaves / dirt / corrosives.
Avoid snow build-up during winter
operation
Provide windbreaks in locations with strong winds.
