INSTALLATION
LIMITATIONS
This unit must be installed in accordance with all
national and local safety codes. If no local codes
apply, installation must conform to the appropriate
national code. The unit is 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 2 for application limitations.
LOCATION
The LA 120 is not designed for outdoor installation. It
must be located within the building structure, either
inside or outside the conditioned space.
The unit should be located as close to the condensing
unit 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 metal or wooden
beams can support them.
Units being installed horizontally can be suspended
from above as shown in Figure 1. Refer to Form 035-
16622-001 for more information on the installation of
the suspension accessory and for the individual load
on each hanger rod.
A field added secondary drain pan may be required in
locations where possible condensate overflow could
cause damage.
RIGGING AND HANDLING
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 card-
board container that covers the entire unit, and strap-
ping that secures the cardboard container 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, make sure that its weight will be distributed
equally.
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.
Spreader bars should be used to prevent
slings from crushing the unit panels and frame.
