Wallboxes
The following instructions are general recommendations
for installing wall intake boxes. Consult the architectural
plans for specific requirements.
Additional materials required to complete 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 wallboxes are illustrated in
p.
110; each lists the wall openings required for wallboxes.
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 outside 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 diamond pattern
expanded aluminum bird screen.
Note: H1 (horizontal) wall models are all unflanged. H2,
V3, and V6 are flanged.
