8.2.5. Filter case maintenance
1) When the filter case is dirty, it can be removed and cleaned.
To remove the filter case, insert a precision screwdriver into the groove of the release lever and push in
direction (1), and slide the filter case in direction (2).
Note) Surface A of the filter case is the sealing surface when vacuum is generated. Handle with care so that the surface is not
scratched or damaged.
Note) Filter case is made of polycarbonate. Avoid chemicals such as thinner, carbon tetrachloride, chloroform, acetic ester, aniline,
cyclohexane, trichloroethylene, sulfuric acid, lactic acid, water base cutting fluid (alkaline).
Note) Do not expose the filter case to direct sunlight for a long period of time.
(Procedure to put parts back together)
2) Make sure that body gasket (B) and the check valve are installed correctly onto the ejector. If they are out
of the place, vacuum leakage may occur.
Note) When selecting pressure switch with the energy saving function or option
“W” for single unit, 2 check valves are installed.
3) Push the filter case in direction (1). Be careful the filter case hook (A) and hook (B) do not touch the body of
the ejector.
4) Slide the filter case in direction (2) while pushing the filter case gently in contact with the ejector. Make sure
that the clip (C) is locked and there is no gap in part (D).
Note) If excess force is applied to the filter case, hook A and B may break. Handle with care.
