2.9 Installation
Installation side selection
Before installing the unit, agree with the customer the
location where it will be placed, taking into account the
following points:
Positioning
Before handling the unit, verify the lifting capacity of the
means respecting the information on the packaging. For
handling the unit on horizontal base use forklift or other
means in an adequate way paying attention on the unit
weight. In case of lifting, insert bars in the proper holes
of the unit base in order to permit the positioning of the
lifting ropes and of the safety cotter pin.
In order not to damage the unit structure by the belts,
use proper protections to be put between the belts and
the unit. Position the unit in the place indicated by the
client by interposing between the base and the support,
a gum mattress (thickness min. 10 mm.) or anti-vibration
feet (optional). Fix the unit verifying that the base is plan
and without inclinations.
Verify the easy access to the hydraulic system and
electrical components. In case of installation in places
where there could be gust, fi xing the unit to the support
properly using guy rope if needed.
Handling and positioning
The units have been designed to be lifted from above by
means of eyebolts and holes in the base members. Use
retractor bars to keep the lifting wires or chains away
from the unit. Lifting procedures provided with the unit
have to be respected.

NO
• The foundation must be able to support the
weight of the unit;
• Safety distances between the unit and other
equipment or structures to ensure that the air in
and out from the fans is free to circulate.
YES
Precautions for dominant winds
Avoid obstacles on suction and discharge sides of the
units. Respect the servicing spaces as shown on the
units dimensional drawings.
In case of presence of dominant winds in the installation
area it is strictly necessary to avoid (for units with
horizontal fl ow fans) that such winds blow in front of the
unit (fans discharge side). In case of unit with vertical
fl ow fans it is strictly necessary to avoid installations
where the dominant winds could cause rejected hot air
to come back to the condensing coils.
If needed, install windbreak barriers (in this case contact
our offi ces).
Precautions against direct sunshine
Direct sunshine can raise the condensation temperature
and it causes the unit stopping or the missing set-up
because of the high-pressure switch intervention.
Precautions against chimney and hot air discharge
Avoid the unit installation lee side near chimney and
liquid and gas discharge.
