Genesis Air Filtration System
Return Air Kit
620412, 620415, 620425 & 620426 Series Installation Instructions
 Installing unit with 3308120 Genesis Air Filtration
System Return Air Kit. For unit with 3105007 or
3105935 Return Air Kit, see page 9.
1. All Non-Center Duct Installations
Note: The Genesis Air Filtration System can be installed on
units that use a center discharge duct through the 14-1/4" x
14-1/4" (±1/8") opening. Installing units with the center dis-
charge duct go to Section 1. "Center Discharge Duct Appli-
cation Installation", on page 12.
a. Check gasket alignment of the air conditioner
over the roof opening and adjust if necessary.
Unit may be moved from below by slightly lift-
ing and moving. See FIG. 12.
• Remove return air cover, ceiling template,
foam divider and air filter from the 3308120
carton.
• Locate the four (8" x 1/4-20) unit mounting
bolts, junction box cover and Romex con-
nector in the 3107180 bolt kit.
• Pull down the units electrical cord and fas-
ten the junction box with screws to the fram-
ing in the front of the 14-1/4" x 14-1/4"(±1/
8") opening. See FIG. 13.
b. Measuring Foam Divider
• Locate the foam divider and insert it cor-
ner to corner in the 14-1/4" x 14-1/4" (±1/
8") opening with the adhesive tape up (Do
not remove paper to expose adhesive). The
foam divider should be level with the ceiling
(±1/4"). Tear off the excess at the pre-cut
perforations in divider. See FIG. 19.
c. Install Foam Divider
• Peel the paper off of the foam divider and
stick it in place on the center of the rear
flange of the return air opening on the ceil-
ing template. See FIG. 20.
d. Install Ceiling Template
• Start each mounting bolt through the ceil-
ing template and up into the unit base pan
by hand. EVENLY tighten the four bolts
to a torque of 40 to 50 inch pounds. This
will compress the roof gasket to ap-
proximately 1/2". The bolts are self
locking so over tightening is not nec-
essary.
