LIMITATIONS
These units must be installed in accordance with applicable na-
tional, local and municipal safety codes.
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 ex-
pense. Refer to Table 2 for Unit Application Data.
LOCATION
This blower unit 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 they can be supported by metal or
wooden beams.
Units being installed horizontally can also be suspended from
above. Refer to the suspension accessory instruction installa-
tion procedures.
CLEARANCES
The clearances listed on the unit dimension drawing (Figure 7)
are required for the proper service and operation of the unit.
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 clear heavy mil bag
that covers the entire unit, and strapping that secures the clear
bag to the bottom of the skid.
These units can be rigged with slings under the bottom skid.
CAUTION: Spreader bars should be used to prevent 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, make sure that its
weight will be distributed equally.
