Preparation of the Wall Case for All Types of Construction

Do not remove the stiffener from inside the wall case or the weather closure panel from the outside face of the wall case until the outdoor grille and chassis are ready to be installed.

Installation of Wall Case in Wall Opening

1.Position the wall case into the wall. The room side edge of the RAB71 or RAB77 wall case should be at least flush with the finished wall for line cord installations and permanent connection installations when no sub-base is used, and should project into the room at least 2-3/8" when a sub- base is used. If the minimum exterior dimensions are not met, refer to page 27 and 28. The outside edge of the wall case should extend at least 1/4" beyond the outside wall. This is necessary for proper caulking, to prevent sealing the drain holes in the rear flange of the wall case, and to facilitate the installation of an accessory drain, if used.

The wall case should be level from side to side and from level to 1/4 bubble tilt to the outdoors. The condensate disposal system in the unit is designed to dissipate the condensate water generated during cooling operation in accordance with ARI standards and actually uses this water for maximum unit efficiency. A level unit will also ensure proper performance of the Internal Condensate Removal (ICR) system optional on heat pump units.

2.The wall case should be secured to the wall at both sides. Use a minimum of two screws or other fastening device on each side. See Figure 2 page 26. Mark the wall case on each side 2" from the bottom and 2" from the top at a point where basic wall structure is located. Drill wall case and use fasteners appropriate for wall construction. All holes for fasteners in the side of the wall case must be at least 2" up from the bottom of the wall case. Never locate screws or put other holes in the bottom of the wall case. The only exception is when an RAD10 drain kit is installed to connect to an internal drain system. See page 36 for RAD10 Drain Kit information.

If the wall opening is greater than the case dimensions, spacers must be used on the sides between the wall case and the wall support structure to prevent distorting the wall case.

3.Caulk or gasket the entire opening on the outside between the wall case and exterior wall surface (4 sides) to provide total water and air seal.

4.Caulk or gasket room-side opening between wall case and interior wall surface (4 sides). Opening beneath or around the wall case can allow outdoor air to leak into the room resulting in increased operating costs and improper room temperature control.

Care should be taken in location of electrical supply entry in relationship to wall sleeve to assure access to receptacle or junction box once unit is installed.

•Refer to page 43 for maximum power cord length.

•Permanent connected units close to finished floor must allow for conduit clearance.

Case Angles

In some installations such as curtain walls, window walls, or where the structural material of the wall is insufficient to support or fasten wall case to, the use of case angles may be used. Case angles are pieces of steel or other material of similar structural strength that are formed to a 90° angle, with holes to fasten the case angle to the wall case and to the structural component of the wall surrounding the wall case.

The following describes the procedure when field fabricated and installed case angles are applied.

1.Position case angles around top and sides of wall case at the desired location. Position case angles vertically on each side of wall case to provide a level installation.

2.Mark wall case through holes in case angles. The lowest hole on the sides of the wall case must be a minimum of 2" above the bottom of the case.

3.For RAB71 wall case drill 5/32" diameter holes at locations marked on wall case in Step 2, and assemble angles to wall case using #10 x 1/2" self tapping screws. For RAB77 wall case follow the same procedure except use a #10 x 1/2" bolt, washer and nut to attach case angles to case. Install screws or bolts from outside wall case.

4.Do not drill any holes in bottom of wall case. Do not distort wall case.

5.Do not use case angles for a lintel.
