INSTALLATION
I.
Install the controller console on or near the target
area. It must be close enough to connect to the
Ion Bar.
II.
Locate and attach the Ion Bar in a position so that
the air ions are directed toward the target area.

outlet.
DESCRIPTION
The Linear Ion Bar Systems have been designed to
effectively eliminate localized static charges which exist
in the work area.
UNPACKING AND INSPECTION
Your controller and bars were carefully packed at the
factory in a container designed to protect it from
accidental damage. Nevertheless, we recommend
careful examination of the carton and contents for any
damage. If damage is evident, do not destroy the carton
or packing material. Immediately notify the carrier of a
possible damage claim. Shipping claims must be made
by the consignee to the delivering carrier.
The Air-Assisted Ion Bars are available in several sizes.
There are 4 Controller options, and several accessory
items. See the following table for the list of available
item numbers.
NOTES:
1. To connect your air or gas to the Air-Assisted Ion Bar,
supply the air/gas to the bar in a 1/4" flexible plastic
tube, inserting the tube into the red collar air fitting
already installed into one end of the Ion Bar. Be sure to
insert the tube snugly into red collar fitting and that it is
deeply seated. To remove the 1/4" air supply tubing,
simply depress the red collar, push in the tube and then
remove.
2. One SPI controller will power up to 40 emitters. It is
possible to daisy-chain bars together as long as the total
number of emitters does not exceed 40.
3. To permit the power supply console unit to supply
more than 1 Ion Bar, you must obtain and attach a
94250 two to one connector for two bars.

HOW TO USE THE CONTROLLER
There are two adjustments that can be made on the
controller: BALANCE and RATE.
The BALANCE of positive and negative ion output can
be adjusted to increase polarity bias by turning the
BALANCE KNOB, and slowly turning the trim pot
CLOCKWISE to increase positive and decrease
negative ON time pulses OR COUNTER-CLOCKWISE
to increase negative and decrease positive ON time
pulses. The RATE or pulse frequency can be adjusted
down to one pulse per second or up to 5 pulses per
second by SLOWLY TURNING THE RATE KNOB trim
pot clockwise to increase and counter clockwise to
decrease the frequency.
REMEMBER:
It is important to verify calibration after any adjustments
and before using your ionizer around sensitive
electronics. Merely repeat above Balance Verification
steps after all adjustments.
IMPORTANT:
Your IONIZER has been designed to minimize effects of
localized static charges. If your processing involves
generation of considerable static charges you may
need more aggressive equipment. SPI has available a
complete line of ionizers; bench top, overhead and hand
ion guns to meet all ionizing requirements.

DISCHARGE TIMES
Recommended air applied: nominal of 2-10 PSI and
max. of 15 PSI.
Measurements are taken with a charged plate monitor
below two consecutive emitters with external air applied
of 5 PSI (nominal).
Pulsing rate is adjustable from 1 to 20 Hz. This will need
to be customized depending on application requirement.
Limited Warranty
ESD Systems.com expressly warrants that for a period of one (1)
year from the date of purchase, our SPI Ion Bars will be free of
defects in material. Within the warranty period, the material will be
tested and replaced at our option, free of charge. Call Customer
Service at 508-485-7390 for a Return Material Authorization
(RMA) and proper shipping instructions and address. You should
