4.2 MINIMUM SPACE REQUIREMENTS
Dimensional drawing shall be respected to avoid:
• Noise
• Incorrect heat exchange and ventilation
• Difficult maintenance or inaccessibility to components
It is fundamental to respect minimum distances on all units to ensure optimum ventilation for the condenser coils. Limited installation
space could reduce the normal air flow, thus significantly reducing the unit performance and considerably increasing consumption of
electrical energy.

CAUTION: in case two units have to be installed side by side, the distance of respect must be doubled.
After the unit has reached the final position, fix the anti-vibration bolts.
4.3 PRECAUTIONS FOR DOMINANT WINDS
Avoid obstacles on suction and discharge sides of the units. Respect the safety distances 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.
4.4 PRECAUTIONS AGAINST DIRECT SUNSHINE
Direct solar radiation can raise the temperature of condensation until it causes the unit shutdown or failure start-up of the
same by action of the high pressure switch.
4.5 PRECAUTIONS AGAINST THE PRESENCE OF FIREPLACES AND EXHAUST HOT AIR
Avoid installation of the machines downwind of chimneys, smokestacks and different effluent discharges.
4.6 PRECAUTIONS AGAINST THE PRESENCE OF FOLIAGE AND FOREIGN BODIES
Avoid installing the unit in the immediate vicinity of plants that can prevent proper intake and discharge air.
4.7 CONTROL OF COMPRESSOR FASTENING
The compressors are fitted on shock absorbers. For fixing through spring anti-vibration mounts, it is necessary to remove
blockages put to fasten the compressors, as indicated on the label on compressors body.
