DUCTWORK

Ductwork should be designed and sized according to
the methods in Manual Q of the Air Conditioning Con-
tractors of America (ACCA).
A closed return duct system shall be used. This shall
not preclude use of economizers or outdoor fresh air
intake. The supply and return air duct connections at
the unit should be made with flexible joints to minimize
noise.
The supply and return air duct systems should be
designed for the CFM and static requirements of the
job. They should NOT be sized to match the dimen-
sions of the duct connections on the unit.
When fastening ductwork to side duct flanges
on unit, insert screws through duct flanges
only. DO NOT insert screws through casing.
Outdoor ductwork must be insulated and
waterproofed.
Refer to Figures 7 and 10 for information concerning
side and bottom supply and return air duct openings.

CONDENSATE DRAIN

Plumbing must conform to local codes. Use a sealing
compound on male pipe threads. Install a condensate
drain line from the one-inch NPT female connection on
the unit to an open drain.
The condensate drain operates in a negative
NOTE:
pressure in the cabinet. The condensate drain
line MUST be trapped to provide proper drain-
age. See Figure 1.
