The Pre-FIIter
The Pre_Filter is located in the front of the [ElectronicFilter.
To clean it, slide it out and rinse thoroughly with clean
warm water. Set it aside to dry.
The Charcoal Ffiter
Although the Charcoal Filter is an optional replacement
filter, we recommend its use for the operation of your air
cleaner to help maintain efficiency.
During normal use, lint and di_t may build up on the Char-
coal Filter and can be removed with a vacuum cleaner
using a brush attachment.
The effectiveness of this Charcoal FUter will gradually
diminish over time. If your unit is used continuously, it
should be replaced every three months. Replacement
filters are available at Sears retail stores #7317.
Reinstalling the Electronic Filter
First, slide the Pre,Filter into tile slots in the front of the
Electron=c Filter and slide the Charcoal Filter into the slots
provided i_1the back. Using the handle, slide the
Electronic Filter inside the cabinet wall
Note: The Pre.Filter will face the outer wall
Washing Tips:
When handling the Electronic Filter, be careful not to
damage wires or metal plates since this could cause
excessive snapping.
After the first cleaning, the metal surface of the Electronic
Filter may not be as shiny as before. This is normal and
does not reduce effectiveness.
