Installation
Horizontal Recessed Mounting
The recessing flange assembly includes pre-cut
flanges, corner transition pieces, mounting screws,
filler pieces and pressure sensitive gaskets. Refer
to
Figures 21 & 22 for typical horizontal installa-
tion
1. Measure and cut the pressure sensitive gaskets
to the correct lengths and attach to the flanges.
2. Starting at a corner, attach the top flange with
the metal cutting screws provided.
3. Press the corner transition pieces onto the end
of the flange and attach the adjoining flanges
and filler pieces at the bottom of the unit. Work
around the unit in this manner until all flanges
and corners are installed.
4. Mounting holes are pre-drilled in the flanges.
Use the assembled flanges as a template to drill
all 7/32’’ mounting holes in the cabinet.
5. Attach the flange section to the unit cabinet
with the mounting screws provided.
6. Open and remove the front acces panel.
7. Tighten the mounting fastener, making sure
that the unit is level.
8. Open the unit access panel and remove the
bottom front panel. See Figure 23.
9. Hoist the unit onto a forklift and mount in place
as described in the Unit Mounting section,
ensuring the unit is secured and aligned in
place, and that the mounting nuts are tightly
fastened.
NOTE: Unit must be mounted level. Coils and
drain pans inside the unit are pitched internally
