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.
