LOCATION AND CLEARANCES
Particular care must be taken when
placing the machine so as to provide
adequate clearance for access to each side
of the machine. Maintenance is mostly done
through the front of the unit, but in a repair
scenario, any panel on any side may need to
be removed to access components behind
them. The minimum space requirements
shown below must be provided around and
above each unit for installation and service
access.

FOUNDATION
All aspects of foundation and support
computations must be in accordance with
national and local codes.
The chiller must be mounted on a level,
non-combustible foundation capable of
supporting the considerable weight of the
machinery. This is particularly important for
rooftop installations. Always make certain
the structure can support not only the full
mass of the chiller, but also the pumps,
piping, cooling towers, etc. as may be
required. The rooftop area should be well-
drained and be at least 7 feet (2m) from the
edge of the roof. Anti-fall measures should
always be taken if the chiller is installed
within 12 feet (4m) of the roof edge.
Additionally, for protection of the roofing
material, it is recommended a suitable
platform or walkway be provided around all
sides of the unit.
If the chiller is to be installed outside, but
at ground level, make certain the concrete
base and the soil beneath are sufficient for
the task. Settling over time could cause the
unit to become un-level, which could have a
serious, negative impact on the performance
and lifespan of the unit. Concrete
foundations are recommended to be sized so
that it extends at least 12” (300 mm) beyond
the unit in all directions in order to
accommodate potential mounting and
anchoring hardware.
