movement is provided by a system blower, located
behind the ionizers and collector cells which exhausts
clean air at a specified rate.
3.1
Power Packs
Each power pack converts 75 watts of 115 volt, single-
phase AC power to high voltage DC for the ionizers and
collection cells. This combination of components is
called a working module.
Standard power packs supply positive DC voltage of
approximately 11 KVDC to the ionizer circuit and 5.5 to
7.3 KVDC to the collection cell.
Power packs are mounted in electrical enclosures on
the component access door. Each power pack supplies
power to a discrete module of components. Each has a
dedicated externally mounted indicator lamp and
illuminates to indicate normal operation.
The maximum total current in the power pack’s high
voltage DC output circuit is 5 milliamperes, rated by UL
as safe for operating personnel. In the event of a short
circuit or overload condition on its output side, the power
pack deactivates and the indicator lamp will not
illuminate. Upon removal of the overload, voltage
automatically returns to normal and the indicator lamp
will illuminate. The power pack is self-protecting against
overloads (e.g., dirty components, short circuits in
ionizer and cell circuits).
When 115 VAC power is removed from the power pack
circuit, an internal resistor bleeds off residual charge
from the ionizer and cell sections. As a precaution,
however, when the component access door is opened,
the blade of an insulated screwdriver should be used to
ground components prior to handling.
3.2
Ionizers
Each ionizer supports nine (9) 15 mil diameter tungsten
steel wires. These wires are spring mounted and exactly
centered between aluminum ground plates. When high
DC voltage is applied to the wires, a powerful field
charges contaminant particles. Special convoluted
insulators separate high voltage from grounded
members.
3.3
Collection Cells
Each cell contains a series of parallel plates, alternately
charged and grounded, whose plates are in-line with the
direction of airflow. Charged plates are connected
electrically and suspended from four (4) triangular
shaped insulators on each end plate of the cell.
3.4
Filters
Prefilters and afterfilters promote even air distribution
across the ionizers and the collector cells. Prefilters trap
large particulate as it enters the system while afterfilters
keep agglomerated dry material from being re-entrained
as cleaned air exits the precipitator. Filters can take
many forms but normally are of the mechanical type,
aluminum metal mesh, encased in an aluminum frame.
3.5
Junction Boxes
Top mounted junction boxes are equipped with terminal
strips for 115 VAC single-phase power entry. UAS layout
drawings and UAS wiring diagrams define the exact
nature of required field connections.

Other Equipment

®
Air Cleaning Systems may be supplied
with an assortment of special-purpose devices such as
plenums and filters. System components may be
shipped skid mounted or as subassemblies. To be sure
that the system and all of its components perform to
specification, care must be taken to understand the
scope of the installation task - from handling to
assembly.

INSTALLATION
4.1
Inspection Note
Upon receipt of your unit, check for any shipping damage.
A damaged carton indicates that the equipment may
have received rough handling during shipping that may
have caused internal damage. Notify your delivery
carrier and enter a claim if any damage is found.
4.2
Storage
If system installation is delayed for an extended period
(one month or more), protect system components as
follows:
1. Store in a cool, dry location. Do not disassemble. Do
not remove components.
2. Cover duct and unit openings with plastic sheeting
and duct tape, plumbing openings with plastic hole
plugs.
3. Cover system with plastic sheeting and seal with
duct tape.

Risk of electrical shock. A residual DC voltage will
remain on high voltage components for a short time
after power is removed. Prior to handling, ground
components using an insulated screwdriver, refer to
Figures 2 and 3.
