Note:

•Handle the case carefully.

•The cardboard stiffener inside the case, and the rear protective panel must remain in place until the chassis is installed to assure case rigidity and squareness.

•If a sub-base is to be used, it may be desirable to assemble it to the case before securing the case in the wall.

Case location

As a general rule the air conditioner should be located in an outside wall to assure proper distribution of conditioned air. It should be located in a portion of the wall where there is no electrical wiring or plumbing, and where there are no obstructions immediately inside or outside.

STEP 1

Preparation of the wall

The wall case should be installed during construction and lintels should be used to support the block above the wall case. The case will not support the concrete block or brick. The case is modular in height and width:

Height — Fits 2 courses concrete block

—Fits 6 courses standard brick

—Fits 5 courses jumbo brick Width — Fits approximately 3 stud spaces.

For existing construction, wall openings must be made. Wall openings of the proper dimensions are essential to avoid the necessity of fillers or additional framing.

STEP 2

Preparation of the case

Do not remove the cardboard stiffener inside the case until the chassis is installed.

If field supplied case angles are to be used and must be installed, proceed as follows:

1.Position the case angles around top and sides of the case at the desired location (front to rear) with angles facing toward rear (outside). Position the case angles vertically on each side of the case to provide a level installation.

2.Mark the case through the holes in the case angles.

3.Drill 5/32″ diameter holes at marked locations

on the case and assemble the angles using only 10×1/2″ screws. Install the screws from the outside of the case.

4.Do not drill any holes in bottom of the case.
