and degrade the performance of the Air Cleaner.
Cleaning
Note: When the air cleaner is installed in 24 V mode,
the LED's on the front of the air cleaner door will indi-
cate when it is time to clean the filters. When the air
cleaner is installed in communicating mode, the LED's
on the front of the air cleaner will indicate when it is
time to clean the air filters. In addition, the comfort
control will also indicate when it is time to clean the
filters.
Cleaning Instructions:
The Air Cleaner utilizes a Pre-Filter and Collection
Cells. The purpose of the Pre-Filter is to capture large
particles before they enter the Collection Cells which
allows the Collection Cells to work more efficiently.
