MAINTENANCE RECOMMENDATIONS (CONTINUED)
CLEAN THE IONIZER WIRES
Particles will normally build up on the positively charged ionizer wires during operation. The ionizer wires should 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 16).
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,
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.
