Vent Extension
Clearance Holes*
* The clearance holes are not marked
on the actual vent extension.
6. Position the vent pipe at the center of the metal wire
grille when using polypropylene louvers. The vent
pipe should have a slight downward slope to allow any
moisture to drain away from the unit as well as being
centered on the metal wire grille.
Ductwork
Ductwork should be designed and sized according to the
methods in Manual Q of the Air Conditioning Contractors
of America (ACCA).
Check unit supply and return air openings for debris
before making ductwork connections.
It is recommended that supply and return duct connections
at the unit be made with flexible joints. If flexible ducts are
used, a 6” sheet metal starter collar is required.
The supply and return air duct systems should be fabricated
per the designed CFM and static requirements of the job
(see Table 4). Ductwork should not be sized to match
the dimensions of the duct connections on the unit.
The return duct should be sealed to the unit casing and
terminate outside the space containing the unit.
Do not screw into the side of the drain pan or the indoor
coil, which is located above the installation bracket.

N/A: Do not operate unit using this blower speed at this external static pressure.
† As shipped speed for Cooling operation. Blower speed must be field adjusted to speed Tap 3 for higher duct static applications.
* As shipped speed for Heating operation. Blower speed must be field adjusted to speed Tap 5 for higher duct static applications.
# As shipped speed for Low Stage Cooling operation (low duct static).
