Filter Function and Conditions Requiring Service
An air filter prevents solid particles and liquid from contaminating components in the vacuum
system.
CAUTION: Examine air filter regularly and empty when necessary.
Liquid must not contact any portion of the filter element; remove trapped liquid regularly.
Replace the element if it has an overall dirty appearance, or if there is a noticeable increase in
the time required to attain full vacuum. (Refer to REPLACEMENT PARTS LIST for filter element
kit.)
Filter Service Procedures
1) Unscrew the bowl (6) from the body (1). Support the body while twisting
the bowl, to protect the vacuum line fittings from being damaged.
2) Determine whether the filter element (4) needs to be replaced (see
Conditions Requiring Service preceding). If so , proceed to step 3.
If not , remove any liquid or contaminates from the bowl; clean the old
bowl seal (2) with mild soap and water; and skip to step 7.
3) Unscrew the element holder (5) and remove all internal parts.
4) Set aside the element, element gaskets (7) and bowl seal for disposal
later.
5) Clean all other internal parts and the bowl, using mild soap and water
only. Do not use any other cleansing agents.
6) Place the new element gaskets and element, along with the old deflector
(3), on the element holder, and screw the assembly back into the filter
body (tighten gently, finger tight).
7) Lubricate the new or cleaned bowl seal (2) 22 , using a mineral base oil or
grease (such as the lubricant furnished in the filter element kit). Do not
use synthetic oils, such as esters, and do not use silicones.
8) Place the bowl seal around the rim of the bowl. Then screw the bowl back
into the body, taking care to avoid contaminating the filter element with
lubricant. Hand-tighten only.
9) Test the vacuum system to be certain the air filter does not leak (see V
ACUUM
T
EST
preceding,
if applicable).
WARNING: When the air filter is being used on a vacuum system, rather than with
pressure, using the twist drain (8) to remove liquid from the bowl is not recommended. Never
disturb the twist drain, as contaminants could lodge in the drain seal and cause a vacuum leak.
22
The filter element kit may contain two sizes of bowl seals (O-ring type gaskets). If so, use the smaller bowl seal; or if in
doubt, compare the old bowl seal to determine the appropriate size.
