Vacuum base
Centering fixture
The assembly station is constructed on a solid heavy base to prevent movement during assembly. The design above is just a typical example and requires 4 appropriately spaced M5 tapped holes.
Procedure
Place the Reservoir Assembly Jig Vacuum base on the heavy base and secure with two M5 screws (91292A192).
Place the 3D printed Reservoir Centering Fixture on top of the Vacuum base and secure it with two M5 screws (91292A193).
Screw the push-to-connect elbow fitting (5779K652) into the back port (1/8 NPT).
Hook up the venturi pump with and appropriately valved air valve and place the O-ring in the center of the Vacuum Jig base (9262K421).
The system is ready to be used for the assembly of the reservoirs.
