INSTALLATION INSTRUCTIONS
Preparation of the wall
The sleeve should be installed during construction and lintels should be used to support the block above the wall
sleeve. The sleeve can not support the load of bricks/ blocks.
For existing construction, wall opening must be created, the proper dimensions are necessary to avoid use of fillers
or additional framing. The sleeve is modular in height and width(refer to Fig 5 & Chart 2).
Height:
Fits 2 courses concrete block
Fits 6 courses standard brick
Fits 5 courses jumbo brick
Width:
Fit approximately 3 stud spaces.

CHASSIS INSTALLATION
1. Remove the cabinet front from the chassis as described in Front Removal.
2. Insert the chassis into the wall sleeve.
Chassis Installation View 1
OUTDOOR GRILLE (OPTIONAL ACCESSORY)
An outside grille must be installed to direct air flow for proper unit operation and also protect the outdoor coil. The
grille must be installed before installing the chassis.
When replacing an old chassis with an existing grille or using a specialized grille in a new installation, please check
with after-sales engineer of supplier to determine if the new chassis should be used with the nonstandard special-
ized grille. An improper outdoor grille can decrease cooling or heating capacity, increase energy usage and shorten
compressor life and possibly void the warranty.
