4. Hook the turnbuckles to the support bars and
then securethe support wires to the eyesof the
turnbuckles (see Fig. 1). Twist the wire at least
four times.
5. Adjust the turnbuckles until the support bars
are securelysuspended
by the support wires. Do
not overtighten the turnbuckles to avoid lifting
or buckling the T-barframework.
6. Lill air cleanerbody into opening and let body
drop into Jshapedportion of support bars.
7. Fasten
air cleaner
body to support barsusing
two #8 self-tapping screws and flat washerg.
Screws
are installed through slotsin endsof air
cleaner
into support bars. Adjust location
of air
cleaner
relativeto support barsvia slotsprior to
tightening of screws.
ELECTRICALINSTALLATION
CAUTION
This ptocedure
should beattempted
only by per-
sons qualified to install electrical wiring. All
wiring must comply with applicablecodes
and
ordinances.
1. Locate an unswitched 120 volt AC, 60 }Jz.
power circuit with a junction box near the air
cleaner
location.
2. Check the circuit breaker or fuse for that cir-
cuit and determine
whetherit is rated15amperes
or 20 amperes(as marked on the device).
The
required copperwire sizewill be:
AWG #14 for 15ampere
circuits.
AWG #12 fot 20
amperecircuits.
3. CAUTION: Turn off the building circuit at the
fuse
or circuit breaker
before
proceeding.
4. Connect the black and white wires from the
pigtails in the air cleaner junction box to the
corresponding
colorsin the supply circuit (Fig.2).

AirCleaner
5. If grounded conduit is used to route the power
wiring to the air cleaner, no further grounding is
neceseary.
[n the absence
of a grounded conduit
connection,the green wire in the field wiring com-
partment should be connectedto a grounded con-
ductor. DO NOT connect the grounding wire from
the air cleaner to the white wire or the building.
The air cleaner frame must be electrically con-
nectedto the frame of the building of the electrical
conduit system. Input electrical power should be
run through flexible conduit as recommended by
the National Electrical Code or your local author-
ity.
COMPLETING
THEASSEMBLY
1. Install electronic
cell.
2. Checkto makesure the electroniccell is oriented
for correct airflow. arrows on side of cell should
point up. The contact board needs to be properly
seated.
3. Install the prefilter.
4. Install the grille by squeezingtwo of the mount-
ing springs locatedalong one side of the grille and
inserting the "legs" of the springs into the slots in
the mounting bars.Besure the grille is oriented so
it will swing up and cover the air cleanercorrectly.
Swing the grille up and attach the remaining two
springs to the other mounting bar. At this point,
simply push the grille toward the air cleaner and
the springs will pull the grille up into its final posi-
tion.
5. Turn electricpower backon and pressHI, MED,
LO button.
6. Make sure fan runs on all three speedsettings.
7. Presstest button. An audible snap indicatescol-
lection sectionof cell is functioning.
8.Cleanup installation
area.
