MAINTENANCE RECOMMENDATIONS (CONTINUED)
CLEAN THE IONIZER WIRES
Particles build up on the positively charged ionizer wires during operation, which need to be cleaned to maintain the highest level
of filtration.
• Clean the ionizer wires at least once a year.
Procedure:
1. Lay the inner assembly on a flat surface with the control electrode facing up (see Figure 17).
2. Slide the control electrode out of the ionizer frame and set it aside.
3. Using 200 grit sandpaper or an abrasive dish scrubber, clean each of the nine ionizer wires. Even if the wires don’t appear dirty,
use the sandpaper to clean each one. Do not use steel wool as this material readily sheds.
4. Replace the control electrode in the ionizer frame, return the inner assembly to the outer housing, reinstall the door, and turn the
ON/OFF switch to the ON position.
5. Return the thermostat Fan and Mode selectors to their appropriate settings.
CLEAN THE INNER ASSEMBLY
Dust will collect on all parts of the air cleaner, which is normal.
• Clean the inner housing and ionizer frame once a year.
Procedure:
1. Use a vacuum with a brush attachment or a cloth to wipe off collected dust on the inner housing and ionizer frame.
2. Return the inner assembly to the outer housing, reinstall the door, and turn the ON/OFF switch to the ON position.
3. Return the thermostat Fan and Mode selectors to their appropriate settings.
APPLICATIONS WITH A HUMIDIFIER
An Aprilaire ® Automatic Humidifier can be mounted upstream from the air cleaner.
CAUTION
Do not install an atomizing humidifier upstream from the air cleaner.
