7.2 Ion Balance / Performance Check
For checking balance and performance a charge plate monitor (CPM) such as SIMCO’S
EA-4 is required. The CPM should have its ground connected to the instrument ground
provided on the rear panel of the Centurion; this jack accepts a standard banana plug.
With the charge plate located 12” from the outlet grille of the unit, the ion balance
control can be checked. Note that if an adjustment to the Ion Balance is required, the
emitters should be cleaned (see 7.3 below) before this adjustment takes place. By using
the CPM to measure discharge times of the charge plate, ion content of the air and ion
delivery to the target area can be verified.
7.3 Emitter Cleaning
Recommended frequency of cleaning is once per week. To clean ion emitters, simply
rotate the emitter cleaner knob located at the center of the fan grille on the rear of the
unit. Rotate the knob clockwise until it stops and release. The spring-loaded emitter
cleaning brush will return to its parking spot.
It is not necessary to turn off the unit during cleaning of the emitters when using the
integrated cleaning brush.
7.4 Emitter Replacement
To replace emitters, the rear of the unit must be removed. Loosen the #8 Phillips-head
screws located on the bottom of the chassis. The rear cover can now swing open for
removal from its pivot pins. The emitters are installed in sockets for easy insertion and
removal. Using a long-nose pliers, pull the emitters out along the radial direction,
gripping the shaft only, taking care not to damage the sharp tip. Position each emitter
carefully during insertion, as excessive force can damage the emitter sockets. Using
long-nose pliers, push the emitters into the sockets along the radial direction.
7.5 Troubleshooting / Diagnostics
This information provides a quick troubleshooting reference for the Centurion single-fan
ionizer. Should any of these possible solutions not solve the problem, contact SIMCO.
