Specifications

Ceiling Mount
The unit must be mounted level and may be hung with
the reinforced rubber straps provided as shown in Appen-
dix E. Check with local building codes regarding the use
of rubber straps in commercial buildings. Attach the straps
to the unit with two #8 screws provided. Then attach the
other end of the strap to the ceiling joists, trusses, custom
frame, etc.
The unit may also be hung with 3/8” [10 mm] threaded
rod and U-channels or angles (field supplied) as shown in
Appendix E.
Rubber vibration isolation may be required and is recom-
mended for quiet operation. In some regions seismic vibra-
tion isolation may be required (isolators field supplied and
specified).
Internal Packaging
Remove access panels and all packaging from the unit.
Note that the reinforced rubber straps for ceiling mount
are packaged and located inside the unit as may be other
remote mounted options and/or accessories. Removal of
all packaging is critical.
Floor Mount
The unit must be mounted level and may be mounted
on a metal or wooden curb (not supplied) bolted to the
floor as shown in Appendix E. Space must be left under
the unit for drain trap height and to allow connection of
drain lines. A gradual slope is required for the condensate
water to drain by gravity (minimum ¼”per foot [6 mm per
305 mm]). If this is not possible, a pump should be used.
See Appendix D for specific trap height and connection
requirements.
IMPORTANT
Do not block access to control box, low voltage terminal
strips or line voltage input as indicated in Appendix E. Do
not block supply or exhaust ductwork and allow for 1” to
2” [25 to 51 mm] of insulation they may have on them.
IMPORTANT
If attachment of the unit to the curb is required, ensure
that screws, bolts and mounting hardware do not inter-
fere with moving parts or that the integrity of the cabinet
insulation is not affected.
