air volume or a brownish color to the filter. If either of these
conditions exist, you should replace the filter by unsnapping
connectors. Depress air line connectors allowing removal of filter.
The filter replacement is sold as Desco Item #60355 (two filters to
a package). Be sure to observe the flow direction on filter when
installing a replacement.
Installation of the Controller and
Ion Python Attachment
The mounting slots on the bottom of the controller allow for easy
mounting of the base. Install screws either on a wall or bench.
Using the mounting slots, place controller on the screws for secure
mounting of the unit. Mounting the controller underneath a bench
or on a wall saves valuable bench space. After mounting the unit,
a locking screw is provided on the back of the unit to prevent
accidental removal.

Neutralization Efficiency (Decay Time)
The comparative neutralization efficiency of ionizers is determined
by a standard test published by the ESD Association Standard
3.1. The decay rates measured using this standard are shown
in the chart below. This performance was measured with the air
nozzle at a distance of 6” from the charged plate and utilizing an
air pressure of 30 PSIG.

Charge Decay Time Constants
Notes: 1) Decay times are from 1,000 volts to 100 volts.
2) The air nozzle’s air stream is
perpendicular to the charged plate.
These units need very little maintenance. In order to maintain
the optimum performance of your unit, the following maintenance
procedures must be performed on a regular basis.
Make sure that the air supply is clean and free of contamination
and moisture. Drain compressor tank and filters periodically.
The filters may require
draining several times
daily, depending on your
compressed air system.
The fuse may be replaced
by removing the power
cord at the back of the
unit and opening the fuse
box at the IEC receptacle.
The controller uses a 1
amp fast acting fuse.
For
safety, do not use other
ratings.

Do not attempt to perform any repairs or adjustments on your
Desco equipment except for those covered in the operation
manual. Self-made repairs could create a hazard and will void the
warranty.
Replacing the Air Nozzle Assembly
The air nozzle and hose assembly is designed to be removed or
replaced by the user in the event of damage or wear. To replace
the assembly, simply unscrew the collar at the base of the hose
and gently disconnect the connector from the receptacle.
To replace the nozzle assembly simply repeat the process in
reverse.
NOTE: Make sure the fittings inside the connector are properly
aligned with their receptacles before tightening the threaded collar.
Replacing the Air Filter of the Ion Python
Periodic replacement of the air filter is recommended for
optimum performance of the ionizer. Compress outer sleeving
away from the filter housing. Examine the filter for any evidence
of contamination. The filter will turn red if there is any oil
contamina tion. If there has been moisture build-up, there will be a
change in
