Installation Considerations
The internal air line normally used to supply the solenoid manifold is instead used to provide
vacuum to the bellows / outer link. You can use one of the passive 6 mm user air lines shown
in Figure 9-12. and Figure 9-13.
Performance Considerations
The exhaust from the internally mounted valve may exceed Class 10 particulate limits.
NOTE: To avoid the issues described above, consider mounting pneumatic
solenoid valves externally when using a Cleanroom robot.
10.4 Cleanroom Option Maintenance
This section provides special maintenance instructions for replacing the bellows used on the
Cleanroom robots.
Cleanroom Bellows Replacement
Use the following procedure to replace the bellows. The part number for the bellows is 04625-
000.
IMPORTANT: Check the bellows periodically for cracks, wear, or damage.
Check the bellows periodically for cracks, wear, or damage. Replace bellows (P/N 04625-000) if
necessary, using the procedure below.
1. Remove all power and air supply from the robot.
2. Remove the lower bellows clamp ring from the bearing ring by loosening the screw on
the clamp.
3. Remove the tool flange.
For the tool flange removal procedure, refer to Remove the Tool Flange on page 120.
