such as trees and buildings to provide a shaded location. This will minimize the solar load on the unit. Avoid ground level
sites that are accessible to the public.
Ensure the mounting location can support the weight of the equipment. Refer to the installation drawing for the non-
charged system weight.
When installing the unit on a roof, ensure the weight is adequately distributed to the load bearing points. For ground
mounted units, install a concrete slab as shown in Figure 4. The slab should extend below the frost line and be at least 2
inches higher than the surrounding grade. The slab should extend at least 2 inches beyond the outer profile of the
condenser on all sides.
Ensure the condenser legs are fully extended to optimize air flow. Secure the unit with fasteners (field supplied by
others) to prevent the system from moving during operation. To reduce the vibration transmission to the mounting surface it is
recommended that vibration isolators (field supplied by others) be inserted between the mounting rails and the base as
shown in Figure 4.

The clearance around the unit to the nearest wall or
obstruction should be at least 1 time’s (1×) the unit’s width
to ensure adequate airflow to the coil(s) (see Figure 5 and
Figure 6). Space multiple units at least 2 times (2×) the
unit’s width when placing them side by side. Ensure hot
exhaust air is not directed toward the air inlet of an adjacent
unit. When placing units end to end, allow at least 4 feet of
space between units. Avoid areas where heavy snow will
accumulate at air inlet and outlet openings.
If the unit(s) are surrounded by three walls or if they are in a
pit, space them at least 2 times (2×) the unit’s width from
the nearest walls (see Figure 6). The top of the unit must
be equal to the height of the walls or the pit. A stack may be
used, if necessary, to extend the air discharge. The height
of the extension must not exceed 10 feet.
