below.
Changing the back panel for use with a 19”W x 21”H (483 mm x 533 mm) wall opening.
Note: Changing the back panel must be done before the unit is mounted on the enclosure.

opening. Each flange is held in position with four screws, two on the side, one at the top and one
at the bottom.
2. Remove the screws and slide the duct flange out so that the holes in the duct flange aligns with
the holes for the larger opening.
3. Replace the eight screws – four on each duct flange.

Wall Sleeve for CEA1012 one ton air conditioners with an economizer
A wall sleeve is required for all installations of the CEA1012 one ton air conditioner if equipped with
an economizer. The wall sleeve has a horizontal divider panel to separate the supply and return air.
If the opening is 19”W x 21”H the wall sleeve, part number S/12544 is required. The S/12544 wall
sleeve has outside dimensions of 17”W x 19”H. If the opening is 28” x 19” (711 mm x 483 mm), the
wall sleeve, part number S/01784 is required. The S/01784 wall sleeve has outside dimensions of 26”
x 17” (660 mm x 432 mm).
For all air conditioners with electric heat, the wall sleeve
MUST
have 1” (25.4 mm) clearance around
all four sides of the opening. Attach the perimeter flange of the wall sleeve to the framed opening
with appropriately sized screws. Since electric heat can be added after the unit has been installed, ICE
recommends that all installations have the 1” (25.4 mm) clearance around the wall sleeve.
When installing the wall sleeve, the supply opening must be on top. The supply opening is smaller than
the return air opening.
