Installation
Moving and positioning the unit
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.
CAUTION!
Do not use forklift trucks to lift the unit from below. If equipment for lifting from above is not available, use rollers to 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).
NOTE: if two units have to be installed side by side, the safety distance must be doubled.
After the unit has reached the final position, fix the ant-vibration bolts.
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.
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.
Precautions against the presence of fireplaces and exhaust hot air
Avoid installation of the machines downwind of chimneys, smokestacks and different effluent discharges.
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.
Control of compressor fastening
The compressors are fitted on shock absorbers. For fixing through spring ant vibration mounts, it is necessary to remove
blockages put to fasten the compressors, as indicated on the label on compressors body.
