Operation
Set the fan speed switch on the rear of the unit to the LOW,
MED, or HI position. Higher airflow will result in faster
neutralization rates. Position the unit so that the maximum
airflow is directed at the items or area to be neutralized.
Turn the unit ON.
When the unit is first turned on, it conducts a self-test. The
audible alarm will sound and then the LED will cycle through
RED, YELLOW, and then GREEN. The LED will remain
GREEN during normal operation.
Balance Adjustment
The Chargebuster Overhead Ionizer is an auto-balancing
unit. However, tuning or manual adjustment can be
accomplished by inserting a small screwdriver or trimmer
adjustment tool into the balance adjustment hole located
on the front of the unit. To increase the output in a positive
direction, turn the potentiometer in a clockwise direction.
Conversely, to increase the output in a negative direction,
turn the potentiometer in a counter clockwise direction.
Once the desired balance point has been achieved, the
alarm reset button must be pressed to set the balance point.
Maintenance / Alarms
It the supply voltage drops from 110 Volts to below 85
Volts or from 220 Volts to below 170 Volts, the unit will shut
down, the audible alarm will beep, and the LED will blink
RED. The unit will automatically reset when the minimum
voltage is restored.
Under normal conditions, the ionizer will attract dirt and dust
(especially on the emitter electrodes). To maintain optimum
neutralization efficiency and operation, cleaning should be
performed on a regular basis.
When the unit enters shutdown mode, ionization will be
stopped, the LED on the front of the unit will change to a
steady RED, and the audible alarm will sound continuously.
If the ionizer enters shutdown mode, it must be turned OFF
and then back ON to reset the unit.
NOTE: The AC power cord MUST be disconnected before
the unit is disassembled for maintenance. The emitter
electrodes should be cleaned using the alcohol cleaners
included or a swab wet with Isopropyl alcohol. First, turn
the unit OFF and unplug the power cord. Then remove the
back cover by disengaging the 4 screws on back. After
cleaning the emitter electrodes, reattach the back cover
using the 4 screws. Plug in the power cord and turn the unit
back ON.
Figure 1. Desco Emit Overhead Ionizer
Description
The Desco EMIT
/
is a three fan, dual steady
state DC auto-balancing overhead ionizer. The unit
is normally hung from the ceiling above the area to be
neutralized. The ionizer’s neutralization time will be best
approximately 24” to 48” directly above the work surface
and will increase as the distance from the unit increases.
Installation
Remove the ionizer from the carton and inspect for damage.
Included with the unit should be:
1. Hanging kit
2. Power cord
3. Emitter point cleaner
The input voltage should be set to your specification prior
to shipping. It can be verified or reset by removing the top
of the case by disengaging the 4 screws. NOTE: The AC
power cord MUST always be disconnected before the unit
is disassembled.
Input voltage is selected with the two internal jumpers on
JH1. For 110 volt jumper setting, a jumper must be in place
shorting pin 1 to 2 and another shorting pin 3 to 4. For
220 volt jumper setting, a single jumper must be in place
shorting pin 2 to 3 only.
Before installing the unit, verify that the AC outlet is properly
connected to earth ground. The unit must have a good
earth ground to maintain proper balance. Install the unit in
the desired location, making sure that the airflow will not be
restricted. Be sure the ON/OFF switch, located on the rear
of the unit, is in the “OFF” position. Plug the power cord
into the unit and then into the appropriate AC power source.
Status of the unit can be monitored remotely via the RS485
data ports. Please contact the factory for the necessary
polling utility.
