NOTES:
1. Dimensions in parenthesis are in millimeters.
2. Minimum opening sizes apply to all wall
openings.
3. Proper building practices must be used when
constructing a wall opening to support a
PTAC wall sleeve and chassis. If practices are
unknown consult your local architect or build-
ing contractor.
4. Installed wall sleeve must be level from side
to side and front to back (do not use rails to
level sleeve).
5. If wall sleeve extends into the room more than
4-in., an accessory subbase or field fabri-
cated front support should be used to prevent
wall sleeve from tipping forward.
6. For all applications with an accessory
subbase, wall sleeve must extend into room
3

-in.
(83 mm) minimum from floor.
7. For all applications with an accessory lateral
duct, sleeve must extend into the room 3-in.
(76.2 mm) minimum. In applications where
the sleeve will not extend a minimum 3-in.,
the lateral duct mounting brackets must be
mounted on the wall sleeve prior to wall
sleeve installation.
8. Remote control models, “RC” and “RP” units,
use low voltage connections (24 volt AC).
9. 265 volt cord connected units must plug into a
265 volt electrical subbase per UL require-
ment (or hardwire can be used).
10. The 265 volt electrical cord is approximately
15-in. long from where it exits the front panel.
