LIMITATIONS

These units must be installed in accordance with applicable na-
tional, local and municipal safety codes. Refer to Table 1 for
Unit Application Data.

If components are to be added to a unit to meet local codes,
they are to be installed at the dealer's and/or the customer's ex-
pense.

LOCATION

Use the following guidelines to select a suitable location for
these units.

1. The condensing unit is designed for outdoor installation

only. The condenser fans are the propeller type and are not
suitable for use with ductwork.

2. The condensing unit and the evaporator blower should be in-

stalled as close together as possible and with a minimum
number of bends in the refrigerant piping. Refer to “REFRIG-
ERANT PIPING” for additional information.

3. The condensing unit should not be installed where normal

operating sounds may be objectionable. On either rooftop
or ground level installations, rubber padding can be applied
between the base rails and their supports to lessen any
transmission of vibration.

ROOF-TOP LOCATIONS

Be careful not to damage the roof. Consult the building contrac-
tor or architect if the roof is bonded. Choose a location with ade-
quate structural strength to support the unit.

The condensing unit must be mounted on solid level supports.
The supports can be channel iron beams or wooden beams
treated to reduce deterioration.

A minimum of two (2) beams are required to support each unit.
The beams should: (1) Be positioned perpendicular to the roof
joists. (2) Extend beyond the dimensions of the unit to distribute
the load on the roof. (3) Be capable of adequately supporting
the entire unit weight. Refer to Figure 1 and Table 2 for load dis-
tribution and weights.

These beams can usually be set directly on the roof. Flashing is
not required.

NOTE: On bonded roofs, check for special installation require-

ments.

GROUND LEVEL LOCATIONS

The units must be installed on a one-piece level concrete slab
with a minimum thickness of 4 inches (100mm). The length and
width should be at least 6 inches (150mm) greater than the
units overall base dimensions. Refer to Figure 4.

Footers under the slab that extend below the frost line are rec-
ommended. Any strain on the refrigerant lines may cause a re-
frigerant leak. The slab should not be tied to the building
foundation because noise and vibration will telegraph.

A unit can also be supported by concrete piers. These piers
should (1) extend below the frost line, (2) be located under the
unit's four corners, and (3) be sized to carry the entire unit
weight. Refer to Figure 1 and Table 2 for the center of gravity
and unit weight.

CAUTION: Care should be taken to protect the unit from tam-

pering and unauthorized persons from injury.
Screws on access panels will prevent casual tam-
pering. Additional safety precautions such as
fences around the unit or locking devices on the
panels may be advisable. Check local authorities
for safety regulations.

RIGGING AND HANDLING

Exercise care when moving the unit. Do not remove any pack-
aging until the unit is near the place of installation.

Rig the unit by attaching nylon straps with hooks to the lifting
holes provided in the base rails. Spreaders, whose length ex-
ceeds the largest dimension across the unit, MUST be used
across the top of the unit if the rigging height above the top of
the unit is less than 5 feet (1.5m). See Figure 2.

WARNING: Do not use straps under the unit or through the fork

lift slots for lifting purposes. Sharp metal edges can
damage the straps and could result in personal in-
jury or equipment damage.

BEFORE LIFTING A UNIT, MAKE SURE THAT ITS WEIGHT
IS DISTRIBUTED EQUALLY ON THE STRAPS SO THAT IT
WILL LIFT EVENLY.

Units may also be moved or lifted with a forklift. Slotted open-
ings in the base rails are provided for this purpose. The 090
MBH unit may be lifted from either the LH or RH side - under the
unit.

LENGTH OF FORKS MUST BE A MINIMUM OF 42" (1066mm)
for 090 MBH units or a MINIMUM OF 54" (1372mm) for 120 MBH
units when lifting across the long dimension.

Remove the nesting brackets from the four corners on top of
the unit. All screws that are removed to take these brackets off
must be replaced on the unit.
