INSTALLATION
The following is a typical installation of the air cleaner on
a "Highboy" furnace (Figure 8).
1. Placethe airfiltercleaneronthefloor. Stand it upright
with the power door facing you (Figure 4). If a horizon-
tal installation is being planned, lay the cleaner on its
side, this will help you to visualize the relative location
of all parts.
Allow ample space for wiring and servicing the power
supply box (Figure 13).
2. Release the latch, remove the power pack (by grasp-
ing handle and pulling power pack away from cabinet)
and set it aside. Remove the collecting cells and pre-
filters. Set pre-filters and cells aside in a safe location
until the cabinet is installed.
3. Set the cabinet next to the furnace. If necessary,
enlarge the opening in the furnace (if possible) to
match the opening in the cabinet.
If the furnace opening cannot be enlarged, a transition
fitting should be used. (Figure 3).
The cabinet can be attached directly (Figure 13), or a
starting collar can first be fitted to the furnace inlet. A
butt or slip joint can be used.
Securely attach the cabinet to furnace inlet, using at
least two of the mounting holes on each side of the
cabinet.
4. Using butt joint, attach duct work (normally an elbow)
to the upstream side of air cleaner cabinet. (Note the
use of the sheet metal turning vanes inside the elbow
to improve air distribution over the face of the cells.)
(Figure 14)
NOTE: An optional method of attaching duct work to the
cabinet is to modify the cabinet (Figure 15) by bending the
tabs outward at a 90 ° angle and attaching duct work to
tabs.
Transition Fittings
If the air duct does not fit the cabinet opening, a transition
fitting should be used. Gradual transitions are preferred
for greatest efficiency. Not more than four inches per
linear foot (approximately 20 ° angle) should be allowed
(Figure 3).

Connect the vertical duct section to the elbow. Wedge
a wood block between floor and elbow for support
(Figure 16).
Seal all joints in the return air system downstream
from the air cleaner with duct tape to prevent dust from
entering the air stream. Tape is usually applied on the
outside of ducts, but may also be applied on the
inside, or both.
