INTRODUCTION
Thru-the-Wall electronic air cleanersare designed to provide
maximum air cleaning in applications where a single central
return air duct is employed, or where the central heating or
air conditioning is in a limited access area. The
Thru-the-Wall units may be installed in the wall such as in
closet installations or in the ceiling with attic type
installations.
This manual contains essential information for locating,
installing, operating and servicing your electronic air
cleaner. Before installing and using your air cleaner, be sure
to read these instructions carefully and observe _them in
order to derive the maximum benefits from the superior
performance built into the unit and help to avoid needless
service costs that result from causes the manufacturer
cannot control and cannot be covered in the warranty.
The units are available in three models:
Model TTW-10 designed for an air volume of up to 1,000CFM
Model TTW-14 designed for an air volume of up to 1,400 CFM
Model TTW-20 designed for an air volume of up to 2,000 CFM

HOW YOUR AIR CLEANER WORKS (See figure 1.)
Dirt laden air enters the unit from the room. It passes
through the screen (A) first where large particles (hair, lint,
etc.) are trapped. Smaller particles (smoke, dust, pollen,
etc.) passthrough this screen and enter the Ionizing Section
(B). Here each tiny particle receives a positive electrical
charge. These charged particles then enter the Collection
Section (C) which consists of a series of aluminum
plates.., alternate plates are charged positive.
The positive charged particles are repelled by the positive
plates and attracted to the negative plates where they are
collected - just as amagnet attracts iron filings.

UNPACKING AND INSPECTION
1. Unpack and carefully remove air cleaner from carton.
2. Stand air cleaner upright on floor.
3. Release two knurled screws (F]G. 2) at upper edge of
grille, open grille and slide it out of hinges at bottom by
moving it to the left.
4. Rotate two screen retainer latches either left or right to
clear screen. Lift screen out.
5. Remove three screws, one at each end and one at
center of electrical enclosure cover and remove cover.
6. Grasp the two spring clips at the points (A, FIG. 3) and
pull the cell out at the bottom. The collection cell will
move outward approximately three inches where it will
be retained by the safety spring clip at location (B,
FIG. 3). Depress this safety spring clip to free the cell
at the bottom.
7. Grasp the cell at both sides and tilt it rearward at the
top to slide the retaining pins out of their slots and lift
the cell out of the cabinet. Place cell in a safe location•

LOCATING THE AIR CLEANER
Your thru-the-wall Electronic Air Cleaner ismounted at the
return-air duct inlet. (See figures 4 through 7.) It works
equally well in either high or low wall installationsl or in
the ceiling. It can be used with any type of forced-air
heating or cooling system.
In most cases, return-air ducts are located just inside the
wall (or ceiling) grille. When the air cleaner is flush
mounted it will extend through the wall cutout and into
the return-air duct. If the return-air duct is located at a
distance from the wall (or ceiling), extend a connecting
duct to the rear of air cleaner frame with sheet metal
screws.
NOTE: Always tape all ductwork joints with duct tape to
prevent dirt-laden air from entering ducts.
After deciding upon the exact,location, make.sure of the
following before cutting out wall or ceiling area:
1. Exact location of return-air duct behind the wall (or
ceiling).
2. Location is free of obstructions, such as steel support
beams, piping or electric wiring.
3. Access to inner areafor wiring connections.
4. Return-air duct is deep enough to accommodate air
, cleaner (6 inches, seefigures 4 through 8.)
5. Enough room is llft at a corner or wall offset to permit
installation of the grille. (See figure 8.)

MECHAN ICAL INSTALLATION
Remember that allowance must be made for the grille to
swing down so that the cell can be removed by. pulling it
straight out of the cabinet. (Figure 9).
DUCT WORK CONNECTION
If the duct work to be used is larger or smaller than the
recommended framing sizes, atransition should be installed
between the duct work and the air cleaner to insure
maximum filtering efficiency. The expansion or contraction
rate of the transition should not exceed the ratio of 1 to 3.
(Seefigure 10)
Once the duct connection to the framing is completed, the
air cleaner frame (cabinet) may be inserted into the framing
cavity.
Before inserting the cabinet, one of the three knockouts
(figure 15) should be removed for insertion of the 120 VAC
input wiring.
After properly positioning the cabinet, it may be fastened
to the framing either by using the mounting holes in the
inside walls of the cabinet or the mounting holes in the
front flanges of the unit.

INSTALLATION
CAUTION: READ INSTRUCTIONS COMPLETELY
BEFORE STARTING THE INSTALLATION.
1. Mark the cutout area. (See figures 8 and 12 through 14
for dimensions.)
2. Drill holes at the corners of area to be cut out to
permit insertion of saw blade. (See figure 11.)
•_ Carefully saw out wall or ceiling area exactly as
marked. Remember the frame flange is only 3/4-inch
wide. It will not cover an oversize or irregular cutout.
4. Figures 12,13 and 14 show several possible situations
that will be apparent when the cutout is finished. With
standard stud spacing you will run into either one or
two studs. They must be cut and the section removed
at air cleaner location.
5. Install headers all around air cleaner opening (four
sides). This will provide good support of air cleaner and
restore the original wall strength. Use basic concepts
shown in figures 12 through 14 if your wall differs
from the diagrams shown.
NOTE: Thesame method for framing the air cleaner cutout
:_, be applied to ceiling joists, when a ceiling installation is
required.
6. Cut out required opening in return-air duct. The duct
cutout should fit air cleaner cabinet as closely as
possible. If duct is more than six inches from wall
surfac'e, install a connecting duct between air cleaner
cabinet and existing duct. (See figures 5 and 6.)
7. Slide the frame assembly into the finished cutout.
Make sure it fits properly, then remove it.
*Dimension "'A'" in figures 12 through 14 are asfollows:

,Prepare air-cleaner cabinet for electrical connection as
follows:
a. Determine location of power supply source which
will dictate the location of electrical wiring.
b. Three knockouts (figure 15) are located in upper
right-hand corner of cabinet. Abuilt-in "J" type
junction box is included. Secure wiring with
accepted hardware.
c. The usual knockout location is at upper rear of
cabinet. If an obstruction, prohibits this location,
useeither of the two other knockouts.
d. Allow at least 10 inches of wire lengths on inside
of cabinet for connection to air-cleaner wires.
9. Connect air-cleaner to existing wiring.
Wiring to the air cleaner must comply with local
electrical codes. For this reason, specific wiring
instructions are not given. The color coding of wires
out of the female power receptacle are white and
black. They should be matched to wires of the same
color from electrical power source (figure 18). Connect
ground wire from power source directly to the green
grounding wire provided in the junction box area.
This Thru-the-Wall electronic air cleaner is equipped
with a solid state Air Flow monitor (figure 16) that will
automatically turn your air cleaner ON or OFF when-
ever the furnace fan is running.
10. Install frame assembly in wall opening:
a. Slide air cleaner cabinet into wall opening.
b. Secure the cabinet in opening with nails, or screws,
through the 12 holes provided in face of flange
(figure 17), or through holes in cabinet walls.
C,
d.
CAUTION: On ceiling installations, be sure to use
all 12 flange holes to support full weight of air
cleaner.
If an extension duct is required, install it now.
Reach through air cleaner cabinet and tape all
joints made into ductwork.

power source to green grounding wire in junction
box.
c. Install electrical enclosure cover with three screws.
(See figure 2.)
12. Install the cell.
a. Grasp the cell firmly, holding it at a slight angle
with the cabinet (out at bottom). The arrow on top
of cell should point inward.
b. Insert cell at the top and engage retaining pins
(FIG. 19)into their respective cell-retaining slots,
then slide cell outward until retaining pins are at
bottoms of slots.
c. Allow cell to swing inward at the bottom, pushing
slightly until it "clicks" over the safety spring clip
at bottom center of cabinet.
d. Continue to push cell inward at bottom until it
latches into the spring clips {one at each side of
cabinet). Make sure both clips are latched. (See
FIG. 19).
13. Install screen and grille.
a. Drop screen behind two screen clips at bottom of
cabinet and fasten at upper edge with two spring
retainer latches. (See FIG. 2)
b. Engage pins at lower edge of grille into their mating
hinges. Slide grille toward the right until hinge pins
are fully seated.
c. Leave grille open until after operational tests have
been performed.
CAUTION: When installing the cell on ceiling
installations, make sure it is latched securely in cell
frame before releasing it. (See figure 20.)

OPERATION
1. Turn on furnace or air conditioner to get air flow
through the duct.
2. Press the lower section of "ON-OFF" rocker switch
(Figure 21 ).
3. Close the grille by rotating into position on
the cabinet (fig. 19). Lock in position with
two knurled screws.
NOTE: Your air cleaner is equipped with an air sensing
device. It may provide a short delay before the operating
light comes on.
IMPORTANT - Occasionally, you will hear a sharp
snappingsound (called arcing) coming from the air cleaner.
Arcing is a normal phenomenon. It can result from the
collection of especially large particles. It occursmore often
in e new installation. Later on, arcing may occur when the
cell has become loaded with dirt and needs washing, or
when still damp after washing. The presence (or absence)of
this sound normally does not mean that the unit is
defective.
