SAFETY CONSIDERATIONS
Read and follow manufacturer instructions carefully. Fol-
low all local electrical codes during installation. All wiring
must conform to local and national electrical codes. Improper
wiring or installation may damage air cleaner.
Recognize safety information. This is the safety alert sym-
bol
. When the safety alert symbol is present on equipment
or in the instruction manual, be alert to the potential for person-
al injury.
Understand the signal words DANGER, WARNING, and
CAUTION. These words are used with the safety alert symbol.
DANGER identifies the most serious hazards which will result
in severe personal injury or death. WARNING signifies a haz-
ard which could result in personal injury or death. CAUTION
is used to identify unsafe practices which would result in minor
personal injury or property damage.
Installation and servicing of air-conditioning equipment can
be hazardous due to system pressure and electrical compo-
nents. Only trained and qualified service personnel should
install, repair, or service air-conditioning equipment.
Untrained personnel can perform the basic maintenance
functions of cleaning and replacing filters. All other operations
should be performed by trained service personnel. When work-
ing on air-conditioning equipment, observe precautions in the
literature, tags and labels attached to the unit, and other safety
precautions that may apply.
Follow all safety codes. Wear safety glasses and work
gloves.
GENERAL
The electronic air cleaner is designed to remove atmospher-
ic and household dust, pollen, mold spores, bacteria, insecticide
dust, animal dander, coal dust, cooking smoke and grease, and
tobacco smoke particles down to 0.01 micron.
First the prefilter removes all large visible particles such as
lint or hair. Then the electronic air cleaner ionizes the particles
in the air (the particles are given a strong positive electrical
charge). The particles are then attracted to grounded plates and
collected. Pollutants are held onto the plates like a magnet until
cleaning when they are washed away. Optional carbon filter(s)
then remove the odors from the air.
The electronic air cleaner is available in 4 different models
and 3 different airflow capacities: 1200, 1400, and 2000 cfm.
See Table 1. The electronic air cleaner is adaptable to all
residential forced air furnace or cooling systems. It must be
installed in the return air duct, as close to the blower compart-
ment as possible. This location provides the most even airflow
across the collecting cells and allows the electronic air cleaner
to keep the system motor and blower clean.
Regular maintenance (cleaning of cells and filters) is
required by the home owner.
COMPONENTS
See Fig. 1 for a description of the electronic air cleaner.
Cabinet —
The cabinet is constructed of heavy gage galva-
nized steel. Holes are provided in the cabinet for easy mounting
in the ductwork or air-handling equipment. See Fig. 2 for cabi-
net dimensions.
IMPORTANT: Read entire instructions before install-
ing the air cleaner.
Before beginning any installation or modification, be cer-
tain that the main line electrical disconnect switch is in the
OFF position. Electric shock could result. Tag disconnect
switch with suitable warning labels.
