*Using electronic air cleaner outside specified airflow range is not recommended.
Prefiltered air then passes through a 2-stage electric cleaner. In the
first stage, all airborne particles, even submicron size, are electri-
cally charged (positive) as they pass through the ionizer. The
ionizer field is setup by a corona discharge emanating from fine,
tightly strung wires suspended between 2 adjacent flat plates. In
the second stage, charged particles pass into an intense electrical
field established between alternately charged and grounded paral-
lel plates. Here positively charged particles are attracted to ground
plates and are deposited out of the air stream.
Air Cleaner Construction
The air cleaner is easy to install, operate, and maintain. Its basic
components are:
1. CABINET — mounts to existing ductwork; houses the col-
lecting cells and prefilters.
2. COLLECTING CELLS — collect dust, dirt, and other par-
ticles in the air. They contain ionizing and collecting sections
as described above. Cells must be installed with ionizing wires
on air intake side. A spring contact is located on top of each
cell and must be in position to make contact with contact
board assemblies on bottom of power supply. (See Fig. 3.)
3. PREFILTERS — trap large particles before they enter collec-
tor cells.
4. POWER SUPPLY ASSEMBLY — contains indicating lights,
solid state power supply, contact boards, and electrical con-
trols including ON/OFF switch and safety interlock switch. It
also includes a wiring compartment located at rear of the
power supply assembly.

PLANNING AN INSTALLATION

Step 1—Application
This air cleaner is intended to be used in return-air duct of a forced
air heating, cooling, and ventilating system.

The air cleaner should be installed in system so that all system air
is circulated through the air cleaner. The air cleaner will only
remove airborne contaminants delivered to it. Maximum perfor-
mance is obtained when system blower is set for continuous
operation.
Never use air cleaner to collect grease or other flammable
contaminants.
Step 2—Installation Requirements
The required location for the air cleaner is in the return-air next to
the blower compartment. In this location, the blower motor and
cooling coils will be kept clean.
Do not install the air cleaner in the discharge duct.
Before installing the air cleaner consider the application. (See Fig.
9 to 14.) If a transition is required refer to section entitled
"Transitions." The unit must be readily accessible for periodic
inspection and cleaning of prefilters and electronic cells to
maintain maximum efficiency and trouble-free operation.
Step 3—Air Conditioning
The air cleaner should be installed upstream of cooling coil. This
will keep coil clean and reduce air conditioning coil maintenance.
Improved cooling efficiency is the result which directly affects
energy costs. If air cleaner is downstream of cooling coil,
condensation will form on cooled collector plates when air
conditioner cycles. This will allow water droplets to form on
collector plates and cause nuisance arcing. Arcing will reduce air
cleaner efficiency and reduce life of high-voltage power supply.
