GENERAL
This instruction covers the field assembly and installation of
these supply air plenum accessories.
Each plenum is fully insulated and finished to match the exte-
rior of the indoor unit. All joints are gasketed to provide air
tight seals.
These accessories can be applied with either vertical or hori-
zontal units that will be located in the conditioned space.
They are designed for “free blow” operation and should never
be applied with supply air ductwork.
Their double deflection metal grilles can be adjusted to vary
the throw, spread and drop of the supply air per Table 2.
The Model 1SP0452 plenum accessory has knockouts for
both the power and the control wiring and these knockouts
will always be used because all of the field wiring must be
routed through the plenum panel.
INSTALLATION
