1. How to insert and disconnect tubes

Tube installation
For Positive-Negative Pressure Union Filter (Filter with a built-in tube fitting

lock-claws bite the tube to fix and the elastic sleeve seal around the tube.

Caution
1. Before connecting the tubes and installing the filter, make sure of the air flow direction. The specified
performance cannot be attained if the filter is placed in the wrong direction.
2. Make sure that the casing is properly fixed and there is no leak after the dust is removed and/or the
element is replaced.
3. When used in a circuit where the vacuum and the vacuum breaking air is interchangeably applied, extra
attention is required since the dust removed by the filter element can be discharged by the vacuum
breaking air.
4. Make sure that the O-ring is not damaged at each overhauling or reassembly. Using a damaged O-ring
can cause leak and/or other function failure.
