METAL CASE EXTENSION FOR WALLS DEEPER THAN 13-1/8" (11-1/8" WITH SUB-BASE)

Field fabricated – ge recommends the use of one of the deeper RAB71 wall cases offered as special order items.

Zoneline units can be installed in walls of greater depth than the wall case. Where the case recession is less than 3" and where it is possible to waterproof the exposed sides and top of the opening, the suggested procedure is to apply a flashing to the bottom of the wall case as shown on page 31. Where waterproofing is questionable or not possible, or for installations in walls of greater depth, the following is a suggested application procedure. It involves the field fabrication of a case extension. Since the wall case is a water bearing container, the extension likewise must also be water bearing and the connection between the two must be watertight. The case extension must contain splitters to prevent recirculation of the outdoor air circuit.

1.The case extension is field fabricated. The extension depth “D” should allow for a minimum outdoor projection of 1/4". This allows for room cabinet clearance to the finished wall and ample surfaces to apply sealant or caulking for a tight weather seal between the completed wall case/extension assembly and the wall opening. It is recommended that the extension be painted and corner and lap joints be additionally sealed with a quality grade sealant.

2.The wall case and extension should be connected prior to installation in the wall opening. A quality grade sealant should be applied to all four (4) butting flanges. Use bolts and nuts or oversized self tapping screws (driven from the wall case to the extension) to attach the two assemblies. Clean all drain holes of excess sealant. The assembly must be free draining.

3.Install flashing, using a quality grade sealant between the flashing and wall as shown in section A-A below.

4.Install the wall case/extension assembly following procedures described for a standard installation. See diagrams below. The assembly should be sealed or caulked to the wall around all four sides both outdoors and indoors.

NOTE: The wall case/extension assembly should be level.
