10.2.2 Dry Filters
Dry filters are those filters which should not get wet. The standard Electrostatic Outer Filter (P/N 708731) is a dry filter.
Cleaning may be completed by vacuuming using a brush attachment on the vacuum hose.
•
Lightly brush the vacuum brush nozzle over the input side of the filter. The brush will help dislodge the particles which
will then be removed by the vacuum.
•
Make several passes moving inline with the pleats of the filter.
•
Visually inspect the filter while cleaning. If the filter material is worn, torn, or coming apart from the frame, it must be
replaced.
