Horizontal Unit Location
Packaged units are not designed for outdoor installation.
Locate the unit in an INDOOR area that allows enough space
for service personnel to perform typical maintenance or
repairs without removing unit from the ceiling. Horizontal units
are typically installed in an attic or crawl space. Never install
units in areas subject to freezing or where humidity levels
could cause cabinet condensation (such as unconditioned
spaces subject to 100% outside air). Consideration should
be given to access for easy removal of the filter and access
panels. Provide sufficient room to make water, electrical, and
duct connection(s).
If the unit is located in a confined space, such as a closet,
provisions must be made for return air to freely enter the
space by means of a louvered door or return duct. Any access
panel screws that would be difficult to remove after the unit is
installed should be removed prior to setting the unit. Refer to
Figure 6 for an illustration of a typical installation. Refer to unit
catalog specifications for dimensional data.
Conform to the following guidelines when selecting a
unit location:
1. Provide a hinged access door in concealed-spline or
plaster ceilings. Provide removable ceiling tiles in T-bar
or lay-in ceilings. Refer to horizontal unit dimensions for
specific series and model in unit catalog specifications.
Size the access opening to accommodate the service
technician during the removal or replacement of the
compressor, control, or blower assembly.
2. Provide access to hanger brackets, water valves and
fittings. Provide screwdriver clearance to access panels,
discharge collars and all electrical connections.
3. DO NOT obstruct the space beneath the unit with piping,
electrical cables and other items that prohibit future
removal of components or the unit itself.
4. Use a manual portable jack/lift to lift and support the
weight of the unit during installation and servicing.

Mounting Horizontal Units
Horizontal units have 4 hanger brackets partially attached at
the factory, one at each corner. Enclosed within the unit there
is a hanger kit hardware bag containing vibration isolation
grommets, washers, screws and a hanger installation
instruction page. One additional screw from the hardware
bag must be added to each hanger bracket before unit
installation.Tighten each screw to 75 in-lbs (8.5 Nm). See
Figure 4. Refer to the hanger installation instruction page
contained in the hardware bag for details of final hanger
bracket attachment and unit suspension. See Figure 4a.
Use four (4) field supplied threaded rods and factory provided
vibration isolators to suspend the unit. Safely lift the unit into
position supporting the bottom of the unit. Ensure the top of
the unit is not in contact with any external objects. Connect
the top end of the 4 all-thread rods, slide rods through the
brackets and grommet then assemble washers and double
nuts at each rod. Ensure that the unit is approximately level
and that the threaded rod extends past the nuts.
Pitch the unit toward the drain as shown in Figure 5 to
improve the condensate drainage. On small units (less
than 2.5 Tons/8.8 kW) ensure that unit pitch does not cause
condensate leaks inside the cabinet.
Horizontal units may also be installed on a base. When
installed on a base or platform the horizontal unit should be
set in a secondary drain pan on top of a vibration absorbing
pad. This is required by many codes. The secondary drain
pan prevents damage to the building structure by possible
condensate overflow or water leakage.
NOTE: The top panel of a horizontal unit is a structural
component. The top panel of a horizontal unit must never
be removed from an installed unit unless the unit is properly
supported from the bottom. Otherwise, damage to the unit
cabinet may occur.
