LOCATION
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 repair scenario, any panel on
any side may need to be removed to access
components behind them.
Finally, as with all mechanical devices, the
unit will have to be replaced someday. Keep that
in mind as well when choosing the final
placement site.
The minimum clearance space is shown on
the chart and diagram below.

FOUNDATION
All aspects of foundation and support
computations must be in accordance with
national and local codes.
The chiller-heater must be mounted on a
level, non-combustible foundation capable of
supporting the weight of the machinery. This
is particularly important for rooftop
installations. Always make certain the
structure can support not only the chiller-
heater, but the pumps, piping, cooling towers,
etc. as may be required. The rooftop area
should be in a well-drained area and be at
least 7’ (2 m) from the edge of the roof. Anti-
fall measures should always be taken if the
chiller-heater is installed within 12’ (4 m) of the
edge of the roof.
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-heater 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 unlevel which could
have a serious negative impact on the
performance and lifespan of the unit.
Concrete foundations are recommended to be
sized so that at least 12” (300 mm) extends
beyond the unit in all directions to
accommodate potential mounting and
anchoring hardware.
