INSTALLATION
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 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 2 for application data.
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
from the unit panels to expose these weld nuts.
Refer to Figures 1 and 3 for their location and 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.
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.
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 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.
Spreader bars should be used to prevent
slings from crushing the unit panels and
frame.
