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.
Filter(s)
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 136). 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
(figure 134) consist of a heavy painted
metal structural frame and renewable Amerglas media.
Turn off unit before servicing to avoid danger of injury from
rotating fans.
Dirty or clogged filters can impact unit performance, resulting
in damage to the unit.

Complete Check, Test and Start
Procedure
(Included in the shipping envelope in the end compartment of
the unit). Provide completed Check, Test and Start procedure to local
Daikin representative and to specifying engineer to verify proper start-
up was completed.
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.
