4.3 Filter Element Cleaning
a)
Holding the element clean side up, gently tap the element to dislodge any large
embedded debris and dirt.
b)
Use only FDC/aerofilter cleaner (P/N 40-15) to clean the filter element.
Severe Conditions:
Soak element dirty side down in a pan of FDC/aerofilter filter cleaner to a depth to
allow complete coverage of filter element. Allow cleaner to permeate for 20 to 60
minutes, depending on condition. Use caution to ensure that dirt is not transferred to
the clean side of the element. Remove element and shake thoroughly to remove dirty
cleaner. Resoak for five minutes in clean FDC/aerofilter filter cleaner.
Normal Conditions:
Spray FDC/aerofilter filter cleaner liberally onto the entire element and allow cleaner to
permeate for ten minutes. Do not use any powered device to spray the filter element.
Alternatively, soak element in a shallow pan of filter cleaner and allow cleaner to
permeate for ten minutes.
NOTE:
DO NOT use any other solvents or materials to clean filter element.
DO NOT use Gasoline
DO NOT use Jet A or Kerosene
DO NOT use Caustic Cleaning Solution
DO NOT use Detergents
DO NOT use Parts Cleaning Solvents
DO NOT use Pressure or Steam Cleaners
DO NOT use High Pressure Hose Nozzles
CAUTION:
Failure to service the element correctly will harm the filter media by
reducing its filtration efficiency, restricting airflow, and/or a reduction in service life.
c)
Rinse the element with low pressure water from a garden hose. Always flush
from the clean side to the dirty side to avoid driving particles further into the filter
media.
d)
After rinsing, gently shake off the excess water and set filter aside. Allow the
element to dry naturally. It is permissible to set the filter element in direct
sunlight to aid drying.
DO NOT use Compressed Air
DO NOT use Open Flame
DO NOT use Hair Dryers or Heat Guns
CAUTION:
Excess heat will cause the filter media to shrink and high pressure air will
open small holes that allow dirt to pass.
