Product Manual

2. Before operating the inPASS™, please check if the circlips (1) is correctly positioned
(supported by the inPASS™ groove and the horizontal face on top of the filter head) just
below the hexagonal nut. In case of any doubts, please contact your supplier.
3. Place the appropriate tool (wrench, spanner) over the hexagonal nut and make sure there is
room for rotational movement as indicated on the lock-out feature.
Rotate the inPASS™ valve over 90° in a fluent motion (to not hinder the air flow) in the
direction indicated on the lock-out feature. Fully rotate the inPASS™ until it is stopped, but
keep in mind the maximal torque values shown in the table below.
4. Slide the lock-out feature back into its original position to restrict the hexagonal nut from
rotational movement.
Use the lock to secure the lock-out feature until the service interval is done.
When in inPASS™ mode, no contaminants are filtered and pressure drop over the housing
will be higher. Therefore the duration of the service events must be kept as short as
possible.
Following steps can be taken to switch back to filter mode after the service event is finished:
1. Unlock and remove the lock from the lock-out feature.
Slide the lock-out feature sideways to free the hexagonal nut for rotational movement.
