3.4 Porting and Duct Work
General Information
Note: The following instructions are for general guidance only. Due to the wide variety of installation
possibilities, specific instructions will not be given. When in doubt, follow standard and accepted
installation practices, or contact Technical Support for additional assistance.
Wall Openings (CEA1012 air conditioner, all CEA1024-1060, and all CEA1030-1060)
Measure the dimensions of the supply and return ports on the unit.
Cut the openings in the exterior wall for the supply and return.
IMPORTANT:
All units with electric
heat must have 1" (25.4mm) clearance on all four sides of the supply outlet duct flange on the
unit. The 1" (25.4mm) clearance must extend on all sides of the supply duct for the first 3 feet (1
meter) from the unit.
IMPORTANT: ICE requires a minimum of 1" (25.4mm)
from the surface of any supply ducts to
combustible material for the first 3 feet (1 meter) of the duct.
Wall Openings (CEA1012 air conditoners with the factory installed economizer)
The back panel of the one ton air conditioner with the factory installed economizer is designed to have
a single opening for the supply and return air. From the factory, the back panel is configured for a 19”W
x 21”H (483 mm x 533 mm) opening, but can be easily changed in the field for a 28”W x 19”H (711
mm x 483 mm) opening. Note: the opening is larger than the wall sleeve to allow a one inch clearance
on all four sides of the wall sleeve to any combustible material. This clearance is
required
per National
Fire Protection Association (NFPA) standards 90A & 90B for any unit with electric heat.
