Filter Pull Setup
Do not operate the unit without filters in
place. Each unit has a filter pull located in
the filter section of the unit. The filter pull
must be setup prior to installing or changing
the filters.
If side access to the filters is desired, then no
further action is required. If bottom access to
the filters is desired, then the filter pull must
be removed.
If unit includes 4-sided filter rack, clips must
be opened to remove filters and filter pull.

2. The filter pull is now accessible. Grasp
the filter pull and lift it approximately
¼" and with moderate force, pull it out
and away from the unit.
Note: Use caution that filters are clear
of access holes so that filter damage
does not occur. See Figure 23.
3. Because the filter pull may be longer
than available room, it may be
necessary to roll, bend or cut the slide
to be completely removed.
