A BREATH OF SPRING-FRESH AIR . . .
YEAR-ROUND

Congratulations on your excellent choice and sound investment
in this addition to your home comfort system.

Y our electronic air cleaner represents both the latest in engineer ­ing development and the culmination of many years of experi­ence from one of the most reputable manufacturers of comfort
systems.

Your new unit is among the most energy-efficient and reliable
air-filtration products available today. To assure its dependabil­ity , spend just a few minutes with this booklet now. Learn about
the operation of your electronic air cleaner and the small amount
of maintenance it takes to keep it operating at peak efficiency.

With minimal care, your electronic air cleaner will provide you
and your family with clean, spring-fresh air — from season to
season, and year to year .

YOUR ELECTRONIC AIR CLEANING
UNIT

MORE THAN JUST A BREATH OF FRESH AIR

The highest value of clean air is in its contribution to the good
health and comfort of you and your family. Additional benefits
include potential savings in home heating, cooling, and mainte­nance costs.

Your new air cleaner will electronically filter out microscopic
particles as small as 0.01 micron. At that size, it would take
100,000 particles to cover the head of a pin. Such particles are
500 times smaller than the smallest grains of dust trapped by
conventional furnace filters.

Airborne pollutants commonly found in the household are lint,
dust, ash, pollen, fungus spores, bacteria, viruses, cooking odors,
fumes, and possibly tobacco smoke.

By ridding your home of most of these pollutants, the whole
family can breathe fresher, safer air. Moreover , family members
suffering from hay fever, asthma, or other respiratory allergies
should find exceptional relief. Electronic filtering removes up to
95% of all pollens.

If your home is equipped with central air conditioning or a heat
pump, electronic air cleaning can optimize your system’s per­formance by keeping the indoor coil clean. At today’s energy
rates, the potential savings can be significant.

Electronic air cleaning removes most airborne grease and grime
particles before they have a chance to settle. Therefore, walls, win­dows, draperies, and furnishings stay clean and bright longer . The
time and money you save from avoidable cleaning and redecorat­ing projects can be dedicated to more rewarding goals.

HOW YOUR AIR CLEANER WORKS

Contaminated air enters the prefilter (the metal mesh filter)
where the larger airborne particles are removed. These include
hair, fibers from carpets and drapes, pet hair, and some lint par­ticles. (See Fig. 1a.)

The air then passes through the ionizer/collector cells. The ion­izer wires produce positive ions that give airborne particles a
positive electrical charge. (See Fig. 1b.)

Opposites attract: Airflow continues, passing between the col­lector plates. The positively charged particles are attracted and
trapped by the negatively charged collector plates. (See Fig. 1c.)
These particles continue to cling to the plates until removed by
you or your service technician.

Meanwhile, the purified air leaves the air cleaner, refreshingly
free of contaminants. This clean air is circulated into your living
space by your heating and cooling system providing clean air for
breathing into your lungs. (See Fig. 1d.)

DUCT-TYPE ELECTRONIC AIR CLEANER (EAC)

The DUCT -TYPE EAC is well suited for home comfort systems
using a gas furnace, split-system air conditioner , or split-system
heat pump. If yours is a DUCT -TYPE cleaner , it is installed near
your furnace or split-system air handler. See Fig. 2 for typical
installations of a duct-mounted air cleaner.
