GENERAL
These instructions give information
relative to the SPU series wall sleeve and
grille installation only. The manufacturer
assumes no responsibility for equipment
installed in violation of any code require-
ments. For other related equipment refer
to the proper instructions.
The grille and wall sleeve are shipped
in separate packages. Material in this
shipment has been inspected at the factory
and released to the transportation agency
in good condition. When received, a visual
inspection of all cartons should be made
immediately. Any evidence of rough
handling or apparent damage should be
noted on the delivery receipt and the
material should be inspected in the
presence of the carrier’s representative.
If damage is found a claim should be filed
against the carrier immediately.
DESCRIPTION
The SPU wall sleeve is designed to pro-
vide the structural support and seal from
the outside elements for the SPU pack-
age system. There is no need to build a
platform base for the SPU. The base of
the sleeve also acts as the drain pan for
the system. A 3/4 NPT nipple is located in
the bottom of the pan to be connected to
the condensate drain plumbing.
LOCATION
The SPU unit is designed for through
the wall installation in a closet with direct
access to the rear of the unit (Fig. 1). The
exterior (grille side) of the unit must have
no obstructions (trees, landscape
materials, or building structure, etc.) within
18 inches. Do not locate two units
adjacent to each other on an inside corner
or anyplace where they may exhaust into
each other.
Provisions should be made to allow for
access to the indoor (rear) side of the unit
for installation and inspection. The closet
door must be centered with the exterior
wall opening and be at least 24” wide by
84” tall. At least three (3) inches of space
is required on the left and right sides of
the sleeve and 8-1/2 inches of space is
required from the rear of the sleeve to pro-
vide sufficient air flow around the SPU unit.
A minimum of 27 inches of unobstructed
space should be provided in front of the
access door to permit removal of the unit
should repair and inspection be required.

INSTALLATION INSTRUCTIONS
4. Install the sleeve into a pre-cut
opening 44”H x 21-5/8”W. Use shims
as necessary to maintain proper
alignment of the sealing surfaces.
Sleeve sides must remain in contact
with the seal frame and parallel with
each other or air leakage will occur.
Note: The factory applies a sealant to
the outside of the interface between
the seal and the sleeve. The installer
is responsible to check this for
damage due to installation and to add
sealant as necessary to ensure that
no air gaps exist.
