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 compo-
nents 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 2 for application data.
RIGGING
Be careful when moving the unit. Do not remove any pack-
aging 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 plastic 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 installation, determine its
center of gravity from Figure 2 and 3, and make sure that its
weight will be distributed equally.
LOCATION
These indoor units are not designed for outdoor installation.
They must be located within the building structure, 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 Fig-
ure 2 and 3 for their location 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.
