MAINTAINING AND REPLACING FILTER
SEGMENTS
A list of lter part numbers, sizes and
quantities are shown on a label located on
each lter segment of each AHU.
Every month, check the cleanliness of the filters, and
if necessary, replace them. Filters should be replaced
when the pressure drop, measured by a manometer,
reaches the prescribed limits for the installation.
Filter Types
Flat, angle, rigid, bag, HEPA and charcoal are the typi-
cal filter types as shown in Figure 65 on page 65.
If your AHU has HEPA filters, the filter frames, bulk-
heads and segment panels are factory sealed, and must
remain sealed for NO air bypass.
