CLEANING PREFILTER(S), CELL(S) AND
POSTFILTER(S)
Sharp edges.
Can cause personal injury.
Carefully handle cell(s) or wear protective gloves to avoid cuts from sharp
metal edges.
Setting a regular cleaning schedule
To ensure optimum performance from the air cleaner, the prefilter(s) and cell(s) must
be cleaned regularly— twice a year with normal use or more frequently with heavy
use. Use the wash reminder schedule below to help establish and maintain a regular
cleaning schedule. Mount the wash reminder schedule in a convenient location.
NOTE: You may let the heating or air conditioning system operate normally while the
cell(s) are being washed. Simply turn off the air cleaner switch.
