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...

Step 4ÐHumidifiers
An evaporative humidifier can be mounted upstream of air cleaner.
It is best to install atomizing humidifier downstream of air cleaner
because hard water salt deposits and water droplets may damage
air cleaner. If an atomizing humidifier must be mounted upstream
of air cleaner:
1. Mount it as far upstream as possible. (Recommend at least 6
ft.)
2. Install standard disposable furnace filter between humidifier
and air cleaner to trap water droplets and hard water salts.

Cabinets will support a maximum weight of 400 lb when
installed beneath a vertical furnace or air-handling unit. When
setting furnace on cabinet, do not drop it into place. Position
furnace correctly on cabinet to prevent a corner from slipping
down and damaging cabinet.
Prior to installing this product:
1. Read rules and instructions carefully for safe operation.
Failure to follow them could damage product or cause
hazardous condition.
2. Check ratings given on product to make sure it is suitable for...

The following procedures will expose electrical components.
Disconnect power between checks and proceed carefully.
Electrical shock can cause injury or death.
The air cleaner is powered by providing 120v, 60 Hz, 1-phase
electrical service to pigtail leads at field wiring compartment (with
knock-out holes) located at rear of power pack assembly. (See Fig.
15.)
1. Turn air cleaner off using ON/OFF rocker switch located on
front panel.
2. Remove power supply cover plate by removing front door and
2 screws...

1. Both input indicating light (green) and output voltage light
(red) should now be on.
2. Check to assure that both lights go out when the cell access
panel is removed, when rocker switch is switched to OFF
position, and when system blower is not running.
MAINTENANCE
Sharp edges. Handle the cells carefully to avoid cuts from the
sharp metal edges.
Step 1ÐWashing Cells and Prefilters
Regular washing is necessary to insure proper performance. A
thorough washing every 2 months will be adequate for most...

· Fluke No. 8021B multimeter or equivalent
· Fluke No. 80K-40 high-voltage probe or equivalent.
Step 2ÐIndication of Electrical Trouble
Air cleaner is equipped with input power LED light (green) and
output voltage LED light (red) for indicating proper unit operation.
When unit is in normal operation, system blower running, access
door in place, control switch in the ON position, and indicating
lights go out, there is an electrical problem.
If green light goes out there is a problem in the primary...

If space between charged and grounded plates is bridged with
conductive or semi-conductive material, a short circuit devel-
ops. The bridging or short may be caused by damaged plates
or foreign material lodged between or on plates.
Since cell is periodically removed from unit to wash away
collected dirt, it is susceptible to physical damage. Also, cell
contains ionizing wires which, due to their function, have to be
designed with minimal structural support and are susceptible
to breakage. However,...
