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.
The emitter electrodes should not require replacement
during the life of the unit with normal handling.
Replacement emitter electrodes can be ordered if
necessary.
Best practice would be to verify the balance of the unit with
a charge plate monitor after cleaning.
Neutralization (Decay) Times
The comparative efficiency of benchtop ionizers is
determined by a standard test published by the ESD
Association: Standard S3.1. Typical positive and negative
decay times (from 1000 volts to 100 volts) measured using
this standard are shown below. The performance of the
ionizer was measured with the unit positioned as shown,
with the fan speed on high, and without a filter.
Figure 2. Neutralization (Decay) Times
Note: Reference ESD STM 3.1-2000. The distance from
the 50680/50681 to the charge plate is 18". (Readings are
typical and taken at maximum fan speed.)

price. Call our Customer Service Department at 909-627-8178 (Chino, CA)
or 781-821-8370 (Canton, MA) for a Return Material Authorization (RMA)
and proper shipping instructions and address. Please include a copy of your
original packing slip, invoice, or other proof of date of purchase. Any unit
under warranty should be shipped prepaid to the Desco EMIT factory.
Warranty replacements will take approximately two weeks.
If your unit is out of warranty, call our Customer Service Department at 909-
627-8178 (Chino, CA) or 01892 665313 (Crowborough, U.K.) for a Return
Material Authorization (RMA) and proper shipping instructions and address.
