Wall Box Installation
The following instructions are general
recommendations for installing wall
intake boxes. Consult the architectural
plans for specific requirements.
Additional materials required to com-
plete any specific installations (such as
duct connections, metal mounting
plates, or flanges) are not furnished by
Trane.
For best results, all air intake boxes
should be removable from outside of
the building. Weep holes must be at
the bottom to permit free drainage. A
positive air and moisture seal should
be provided around all edges.
General Instructions
Trane wall boxes are illustrated in the
dimensional section of this manual.
Dimensions are actual, and may be
used to define the wall opening.
Vertical louvers in the wall intake box
provide extra strength for a high load
bearing capacity. The lintel may be
omitted on masonry wall installations.
Weep holes are provided in the out-
side face of the bottom channel in the
wallbox frame. Install all wall boxes to
permit free drainage through the weep
holes to the outside of the building.
All wallboxes are furnished with dia-
mond pattern expanded aluminum
bird screen.
Note: V1 and V2 (vertical) wall models
are all unflanged. H2, V3 and V6 are
flanged.
Installation in Masonry Walls
A typical method of installing the wall
box in a masonry wall opening is
shown in Figure 1.
Grout the top and bottom of the wall
box frame as noted. A sloped water
dam located in the space between the
unit and wall facilitates moisture
drainage. Grouting at the ends of the
intake box will complete the seal be-
tween the wall box frame and the ma-
sonry opening.
Installation in Curtain Walls
In all cases, the wall intake box should
be caulked to provide a tight, weather-
proof seal, Figure 2.
Note: A minimum of 2-1/8” of clear-
ance must be maintained between the
exterior wall and back of the unit. Fail-
ure to provide this gap will not allow
the wall box to fit properly.
