CAUTION
Turn off unit before servicing to avoid danger of injury from
rotating fans.
Turn off the unit, (fan speed switch or unit on/off switch
is located behind the right front end compartment panel).
Remove the center front panel, pull out the filter and
replace with a clean filter. Replace the center panel and
restart the unit.
Filters should be replaced during the first week of
placing into service to prevent dirt carry-over into the
internals of the unit and back into the classroom, (see
Figure 135). A periodic filter changeout program should
be established. Filters should be checked monthly or
more often if conditions indicate. Filters are included
in all units. Daikin single-use filters are standard on
all but electric heat units, which come with permanent
wire mesh filters. Permanent wire mesh and renewable
media filters are available for non-electric heat units, in
lieu of single-use filters.
Single-use filters feature Amerglas media. They are
•
designed to be used once and discarded.
Permanent filters are metal filters that may be
•
removed for cleaning and reused numerous times.
Renewable media filters
•
heavy painted metal structural frame and renewable
Amerglas media.
CAUTION
Electric heat units should ONLY use permanent wire mesh filters.
Filters other than wire mesh are not intended for electric heat
units, and can cause unit damage, property damage or personal
injury.
CAUTION
Units must have a filter installed when operating. Operation
without a filter can compromise unit performance due to build up
of dust and dirt on components.
CAUTION
Dirty or clogged filters can impact unit performance, resulting in
damage to the unit.
