rate request for inspection by the carrier's agent should be

LIMITATIONS
These 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 codes. Units are de-
signed to meet National Safety Code Standards. If components
are to be added to a unit to meet local codes, they are to be in-
stalled at the dealer's and/or the customer's expense. See Ta-
ble 2 for application limitations.
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 ac-
commodate hanger rods. Knockouts must be removed from
the unit panels to expose these weld nuts. Refer to Figure 1 for
their location and the individual load on each hanger rod.
WARNING: 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 al-
lowed to turn or slip.
RIGGING AND HANDLING
Exercise care when moving the unit. Do not remove any pack-
aging until the unit is near the place of installation.
The packaging consists of a bottom wooden skid that can be
lifted with a fork truck from any direction, a cardboard container
that covers the entire unit, and strapping that secures the card-
board container to the bottom skid.
These units can be rigged with slings under the bottom skid.
CAUTION: Spreader bars should be used to prevent the
slings from crushing the unit panels and frame.
Before rigging any unit, determine its weight from Table 1. Bef-
ore rigging a unit for horizontal installation, determine its center
of gravity from Figure 1, and make sure that its weight will be
distributed equally.
CLEARANCES
All units require certain minimum clearances for proper opera-
tion and service. Refer to Figure 12 for these clearances.
