4-2 Performing Maintenance on the Electrode Needles

Install the Electrode Unit.
Make sure that the lock switch on the
Static Elimination Blower Unit is unlocked,
and then insert the Electrode Unit.
Make sure that the Electrode Unit is
slowly inserted all the way, and then lock
the lock switch to fasten the Electrode
Unit in place.
If cleaning the electrode needles does not improve the static elimination
performance, or the ion level alarm indicator frequently lights, a probable cause is
that the electrode needles have reached the end of their service life. Replace the
Electrode Unit.
An optional Electrode Unit for exchanging (OP-51407) is available.

4-3 Performing Maintenance on the Air Filter
When the blow rate of the static elimination blower has decreased or the air filter has got dirty, perform
maintenance on the air filter on the back panel of the Static Elimination Blower Unit.
Performing Maintenance on the Air Filter
1
Remove the air filter.
Pull the tab on the bottom of the air filter in the direction of
the arrow to remove the air filter together with the cover.
• Be sure to turn off the main power of the Static Elimination Blower Unit
before attempting maintenance. If not, there may be a risk of electric shock
or accidents.
2
Clean the air filter.
Clean the air filter of dust and dirt.
If the dirt is hard to remove, rinse the filter and dry completely
before use.
3
Attach the air filter.
Fit the air filter to the cover and attach them to the back
panel of the Static Elimination Blower Unit.
• Do not operate the blower without the air filter attached. This may cause
malfunction.

When the ion level alarm is output,
removing the cause of the alarm can
restore the normal state. One way of
restoring the normal state is to
perform maintenance on the
electrode needles.
For details on electrode needle
maintenance, see "Performing
Maintenance on the Electrode
Needles" ( page 9).
