CLEAN BLOWER COMPARTMENT
NOTE: The air fi lter cannot remove dirt from blower and ducts.
INSTALLATION
The following is a typical installation of the air fi lter on a
“Highboy” furnace (Figure 7).
1. Place the air fi lter compartment on the fl oor. Stand it upright
with the door facing you (Figure 2). If a horizontal installation
is being planned, lay the compartment on its side, this will
help you to visualize the relative location of all parts.
2. Remove the door (by grasping top and pulling door away
from compartment) and set it aside. Remove 4” fi lter by
grasping it at the top and bottom. Set in a safe location until
the cabinet is installed.
3. Set the compartment next to the furnace (if possible) to
match the opening in the compartment.
If the furnace opening cannot be enlarged, a transition
fi tting should be used. (Figure 3).
The compartment can be attached directly (Figure 12), or a
starting collar can fi rst be fi tted to the furnace inlet. A butt or
slip joint can be used.
Securely attach the compartment to furnace inlet, using
at least two of the mounting holes on each side of the
compartment.
4. Using butt joint, attach duct work (normally an elbow) to the
upstream side of air fi lter compartment. (Note the use of the
sheet metal turning vanes inside the elbow to improve air
distribution.) (Figure 13)
Transition Fittings
If the air duct does not fi t the compartment opening, a transition
fi tting should be used. Gradual transitions are preferred for
greatest effi ciency. Not more than four inches per linear foot
(approximately 20° angle) should be allowed (Figure 3).
5. Connect the vertical duct section to the elbow. Wedge a wood
block between fl oor and elbow for support (Figure 14).
6. Seal all joints in the return air system downstream from the
air fi lter 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.
7. With the air fi lter compartment installed, re-install 4” fi lter
and door. (Figure 2)
MAINTENANCE
The fi ber lter used in this cabinet for air cleaning
must be replaced every 90 to 180 days. Your heating
and cooling effi ciency will decrease due to insuffi cient
air fl ow when fi lter becomes dirty.
CAUTION
!
For maximum effi ciency, your air fi lter should be inspected once
a month and changed if dirt loading is heavy. When changing is
required, the following procedure should be used.
1. Remove door from air fi lter compartment.
2. Remove 4” fi lter and discard.
3. Insert new 4” fi lter by sliding it into the compartment.
(Note direction of air fl ow.)
4. Replace door.
