Trane Flex II Series Installation Operation & Maintenance page 10

CAUTION: in case two stand-alone units have to be installed side by side, the distance of respect must
be doubled.
**: As far as modular units are concerned no side space is required between any of the units and the
adjacent one. The minimum side space of 500 mm featured in Figure 2 is required only for the units
placed at the far sides of the modular system.
After the unit has reached the final position, fix the antivibration 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.
