Preparation
Preparing the Wall
The wall sleeve should be installed during construction and lintels should be used to support the
block above the wall sleeve. The wall sleeve will not support the concrete block or brick. The wall
sleeve is modular in height and width:
• Height; fits 2 courses of concrete block.
– Fits 6 courses of standard brick.
– Fits 5 courses of 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.
NNoottee:: Use lintel to support brick or other materials above the air conditioner case. Lintel is not
necessary if this is under a windowsill.
NNootteess::
• Additional depths are, 16“, 18”, 20”, and 24”. Height and width will stay the same.
• Dimensions may need to be increased to fit unique situations in the field if using case
angles.
• *B , refer to the chart in the section, “Wall Sleeve Dimensions,” p. 5.
