installation.

SAFETY CONSIDERATIONS

Improper installation, adjustment, alteration, service, maintenance,
or use can cause explosion, fire, electrical shock, or other
conditions which may cause personal injury or property damage.
Consult a qualified installer, service agency, or your distributor or
branch for information or assistance. The qualified installer or
agency must use factory authorized kits or accessories when
modifying this product. Refer to the individual instructions pack-
aged with the kits or accessories when installing.

Follow all safety codes. Wear safety glasses and work gloves.
Read these instructions thoroughly and follow all warning or
cautions attached to the unit. Consult local building codes and
National Electric Code (NEC) for special requirements.

Recognize safety information. This is the safety-alert symbol

.

When you see this symbol on unit or in instructions and manuals,
be alert to potential for personal injury.

Understand the signal word DANGER, WARNING, or CAU-
TION. These words are used with the safety-alert symbol. DAN-
GER identifies the most serious hazards which will result in severe
personal injury or death. WARNING signifies a hazard which
could result in personal injury or death. CAUTION is used to
identify unsafe practices which would result in minor personal
injury or product and property damage. NOTE is used to highlight
suggestions that will result in enhanced installation, reliability, or
operation.

INTRODUCTION

Model 9011KAX Electronic Air Cleaner (EAC) is available in 3
sizes: 012 (300 to 1400 CFM), 016 (500 to 1800 CFM), and 020
(700 to 2000 CFM). (See Fig. 1.)

These plate-type air cleaners are designed for use with residential
and light commercial forced-air heating and/or cooling systems.
They may be installed in the vertical or horizontal section of a
typical return-air duct system. (See Fig. 2.)

These air cleaners are easily field-converted from right- to left-
hand units. Cabinets are designed to support up to 400 pounds
when used in under-the-furnace applications.

A.

Cabinet

The cabinet includes an electrical junction box and power safety
interlock, and houses the air cleaner components. These compo-
nents are:

1. Mechanical pre-filters—Expanded aluminum mesh first-

stage filter that removes lint and large dust particles.

2. Cell assemblies—Cells consisting of combined ionizer

wires and collector plates.

Ionizer part of cell has tungsten wires that receive positive
charge and are mounted between grounded aluminum
channels supported by glazed ceramic insulators.

Collector part of cell consists of alternately charged collec-
tor plates.

The EAC components are listed below and shown in Fig. 3.

1. Power door assembly.

2. Two pre-filters.

3. Cabinet containing 2 air-cleaning cell assemblies.

4. A parts bag including electrical bushing, plug buttons, wire

chase, and airflow label.

B.

Power Door Assembly

The power door assembly consists of:

1. Unit operation light, ON-OFF switch, and door attachment

knob—all installed on door cover.

2. Door base plate contains a solid-state power pack that

converts 120vac to high voltage DC (a 240v Conversion
Kit, KEAVC0101240 is available). All wiring is mounted
internally. A line-voltage disconnect (male plug) and high-
voltage buss bar are mounted on the base plate externally.
Four screws must be removed to expose the power pack and
wiring.

The supply circuit to the power pack, which is wired across the
furnace blower motor, is controlled by an ON-OFF power switch.
With the power switch ON (assuming power door is in place and
blower motor is operating), 120vac

±

10 percent single-phase, 60

Hz power is applied to the power pack (240v conversion kit
transformer converts 240v to 120vac). Output of the power pack
assembly is approximately 7300vdc.

These Installation Instructions consist of the following:

Section I—Locating Unit
Section II—Installation
Section III-Electrical Connections
Section IV-Startup and Adjustments
Section V—Routine Maintenance and Service
