HOW THE AIR FILTER WORKS  
Dirty air flows through your return air ducts and enters the  
compartment where particles (hair, lint, etc.) are removed  
by the filter. See figure 1.  
DIRTY AIR IN  
FILTERED AIR OUT  
Filtered air re-enters to the supply duct system of your  
building.

CONSTRUCTION OF THE AIR FILTER COMPARTMENT  
Not only is your air filter compartment easy to install, it is  
also easy to maintain. Its basic components, and their  
functions, are as follows: (See Figure 2)

PREINSTALLATION  
LOCATING THE AIR FILTER  
Your air filter must be mounted in the return air duct of a  
central forced-air system, on the air entering side of your  
furnace. (See Figure 3 for example.)

OPTION  
Select a location that meets the following:  
1. The face of the filter will be at a right angle to the air  
stream.  
(SEE PAGE 7)  
2. Allow 25 of clearance in front of the air filter compart-  
ment door to permit removal of filters.

INSTALLATION  
The following is a typical installation of the air filter on a  
“Highboy” furnace (Figure 7).  
1. Place the air filter compartment on the floor. Stand it  
upright  with  the  door  facing  you  (Figure  2).  If  a  
horizontal installation is being planned, lay the com-  
partment on its side, this will help you to visualize the  
relative location of all parts.  
2. Unscrew the knob, remove the door (by grasping top  
and pulling door away from compartment) and set it  
aside. Remove 5 filter. Set in a safe location until the  
compartment 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 transi-  
tion fitting should be used. (Figure 3).  
The compartment can be attached directly (Figure  
12), or a starting collar can first be fitted 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.

Vanes  
Air Flow  
4. Using butt joint, attach duct work (normally an elbow)  
to the upstream side of air filter compartment. (Note  
the use of the sheet metal turning vanes inside the  
elbow to improve air distribution.) (Figure 13)  
NOTE: An optional method of attaching duct work to the  
air filter cabinet is to modify the compartment (Figure 14)  
by bending the tabs outward at a 90° angle and attaching  
duct work to tabs.  
Figure 13  
Transition Fittings  
If the air duct does not fit the compartment opening, a  
transition fitting should be used. Gradual transitions are  
preferred  for  greatest  efficiency.  Not  more  than  four  
inches per linear foot (approximately 2 angle) should be  
allowed (Figure 3).  
5. Connect the vertical duct section to the elbow. Wedge  
a wood block between floor and elbow for support  
(Figure 15).  
Optional method  
(Bend tabs outward at 90˚ angle)  
Figure 14  
6. Seal all joints in the return air system downstream  
from the air filter 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 filter compartment installed, re-install 5”  
filter and door. (Figure 2)

MAINTENANCE  
1. Removedoorfromairfiltercompartmentbyunscrew-  
ing the knob.  
! CAUTION  
The fiber filter used in this compartment for air  
cleaning must be replaced every 90 days. Your  
heating and cooling efficiency will decrease due  
to insufficient air flow when filter becomes dirty.  
2. Remove 5filter and throw away.  
3. Replace 5filter by sliding it into the compartment.  
(Note direction of air flow.)  
4. Replace door.  
For maximum efficiency, your air filter should be in-  
spected once a month and changed if dirt loading is  
heavy. When changing is required, the following proce-  
dure should be used:
