SHEET METAL INSTALLATION
Air Distribution and Ductwork
The AutoClean operates most efficiently when
all system air is delivered across the electronic
cell at a uniform velocity. Turning vanes should
be added to any return airdrop upstream from
the air cleaner. See Fig. 5.
Gradual transitions to the
AutoClean cabinet are
recommended in all ductwork larger or smaller
than the cabinet opening. If transitions are
used, they should not exceed 20 degrees (4”
rise per linear ft.
Install the Air Cleaner
Mount the AutoClean Air Cleaner as Follows:
1. Fabricate and install the necessary vanes
and transitions.
2. Set the cabinet in position.
a. If feet are used, mount the feet on the
AutoClean cabinet and adjust all four
feet-leveler screws. The bottom of the
cabinet must be level. This will provide
for proper drainage of water from the
bottom of the cabinet. Maximum
adjustment is 1 ¼ in. for each leveler
screw.
b. If hanging brackets are used, make
certain the brackets are strong enough
to hold the cabinet and the cabinet is
attached firmly to the brackets.
c. Leave clearance above the control box
to remove the cover and apply a wrench
to the water strainer.
3. Ductwork preparation
a. Drill clearance holes for sheet metal
screws in the cabinet flanges which will
not cause leaking. Remember that the
ductwork must be water-tight near the
cabinet.
b. Fasten the duct to the inside of the
cabinet flange opening with sheet metal
screws.
c. Use caulking compound (not furnished)
to seal the flange joints and all ductwork
joints on both the inlet and outlet sides.
Seal all joints for at least 3 ft. from
cabinet.
FILTER PLACEMENT
1. Slide prefilters into shield channels and push
all the way to the back of the cabinet.

2. Insert the electronic cells into the cabinet
with THIS SIDE OUT label facing the door
opening. Make certain the arrow stamped
on the cell points downstream. See Fig. 6.
3. Close the door.
