INSTALLATION
5.1
CHOISES OF THE PLACEMENT
Before the installation decide with the client the exact position where to place
the unit, paying attention to the following points:
The base must be designed to bear the unit weight;
Respect the servicing spaces between the units and other machines
or structures in order to permit the free air circulation going in and
out from the ventilators.
Verify the servicing spaces, the condensation/evaporation battery
need minimum space for a correct suction.
5.2
Positoning
Before handling the unit, verify the lifting capacity of the means respecting the
information on the packaging.
For handling the unit on orizontal base use forklift or other means in an
adeguate 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 antivibration feet (optional). Fix the unit
verifying that the base is plan and without inclinations.
Verify the easy access to the idraulic and electric part. In case of installation in
places where there could be gust, fixing the unit to the support properly using
guy rope if needed.
5.3
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.
5.4
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 flow fans) that such
winds blow in front of the unit (fans discharge side). In case of unit with vertical flow 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 winbreak barriers (in this case contact our offices).
5.5
Precautions against direct sunshine
The 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.
5.6
Precautions against chimney and hot air discharge
Avoid the unit installation lee side near chimney and liquid and gas discharge.
5.7
Precautions against foliage and external body
Avoid the unit installation nearby plants which could obstacle the correct air charge and discharge.
Attention
Do not use forklift trucks to lift the unit from below.
If equipment for lifting from above is not available, using rollers may move the unit.
The surface on which the unit is placed must be flat and strong enough to withstand the weight of the unit while running.
In order to reduce the transmission of vibrations to the supporting structures, fit shock absorbers in every fastening point. Rubber shock
absorbers are recommended for units installed on the ground, spring shock absorbers for units installed on roofs. Open spaces around the
unit must be provided for in order to allow for the passage of necessary airflow and in order to allow normal maintenance to be carried out
(as shown on general catalogues).
ATTENTION: in case two units have to be installed side by side, the distance of respect must be doubled.
