3.4 Location & fixings
IMPORTANT
Dust and dirt contamination! Unit life reduction!
The unit should always be
installed in a location that ensures clean air f low. External f ouling of the
condenser f ins also leads to high condensing temperatures or pressures and
will reduce the lifetime of the unit.
It is mandatory to keep a clearance space around the unit as shown in
Figure 32
– see dimensions
in blue colour. Both service access and air f low have been considered in making these
recommendations.
Where multiple units are to be installed in the same location, the contractor needs to consider each
individual case carefully. There can be many variations of unit quantities and available space and it
is not the intention of this manual to go over these. However, in general terms, air by -pass around
each condenser and between the units should always be avoided.
Ideally, the unit should be mounted level on a solid concrete slab with anti-vibration pads between
unit f eet and concrete.
Another factor to consider in finding a good installation site is the direction of the prevailing wind. For
example, if the air leaving the condenser faces the prevailing wind, the air f low through the condenser
can be impeded, causing high ref rigeration temperatures and ultimately resulting in reducing the
lif etime of the unit. A baffle is a remedy for this situation.
