INSTALLATION
LIMITATIONS
Theses units must be installed in accordance with all
national and local safety codes. If no local codes apply,
installation must conform with the appropriate national
code. Units are designed to meet National Safety Code
Standards. 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 expense. See Table
for application data.
RIGGING
Be careful when moving the unit. Do not remove any
packaging until the unit is near its final location.
The packaging consists of a bottom wooden skid that
can be lifted with a fork truck from any direction, a plas-
tic bag that covers the entire unit, and strapping that
secures the plastic bag to the bottom skid These units
can be rigged with slings under the bottom skid.
Before rigging any unit, determine its weight from
TABLE 1. Before rigging a unit for horizontal installa-
tion, determine its center of gravity from FIGURE 2 and
FIGURE 4, and make sure that its weight will be distrib-
uted equally.
LOCATION
These indoor units are not designed for outdoor instal-
lation. They must be located within the building struc-
ture, either inside or outside the conditioned space.
The units should be located as close to the outdoor
units as practical and positioned to minimize bends in
the refrigerant piping. Units being installed vertically or
horizontally can be set directly on a floor or platform, or
they can be supported by metal or wooden beams.
Units being installed horizontally can be suspended
from above. Four 3/8” weld nuts are provided in the unit
frame to accommodate hanger rods. Knockouts must
be removed form the unit panels to expose these weld
nuts. Refer to FIGURE 2 and FIGURE 4, for their loca-
tion and the individual load on each hanger rod.
CLEARANCES
The clearances listed on unit dimensions drawing (Fig.
18 and 19) are required for the proper service and
operation of the unit.
Spreader bars should be used to prevent
slings from crushing the unit panels and
frame.
Be careful when attaching the hanger rods.
Use a washer with a back-up nut on each rod
and tighten down against the cabinet so they
will not be allowed to turn or slip.
