Maintenance and Service 25
NOTE: Some vacuum generators are mounted with screws and nuts or adhesive.
5. Clean the vacuum generator by using compressed air.
Do not use solvent for cleaning.
Removal and Cleaning - Aluminum Body (PN 54965)
1. Remove ORION-2D manifold from front panel as described in Section 4.2.3 on page 16, and carefully
place on a bench top.
NOTE: Remove the muffler and long nipple from the vacuum generator’s exhaust port prior to removing the two
manifold mounting screws.
2. Mount the ORION-2D manifold in a vise. Rotate the vacuum generator counter-clockwise 90
0
on the
elbow fitting that connects it to the ORION-2D manifold body
3. Unscrew the generator from the 90
0
elbow fitting using 7/16" wrench. Remove any remnants of Teflon
tape from the threads.
4. Clean vacuum generator in solvent. Blow dry all passages with compressed air.
Installation - Plastic Body (PN 57026)
There are numerous fittings that come with unit. For this application install the following per manufacturer’s data
sheet and discard the rest. Using the 9/16" wrench install the compressed air port (top/input), male 5/32" tube
adapter fitting, and the vacuum port (front/output), 5/32" tube female fitting.
1. Install vacuum generator on the two studs with the compressed air port (top/input) pointing upward.
Using nutdriver, install and tighten nylon spacers (PN 60472).
NOTE: Some vacuum generators are mounted with screws and nuts or adhesive tape.
2. Replace nylon tubing in the compressed air port (top/input) and the vacuum port (front/output) of
vacuum generator.
3. Fill the cylinder to approximately 1000 PSIG and check all fittings for leaks. If there are no leaks fill
nitrogen supply cylinder to maximum pressure. See Section 2.1 on page 4 for cylinder refilling
procedure.
4. Install panel/chassis assembly in its enclosure as described in Table 4.2.1 on page 14.
Installation - Aluminum Body (PN 54965)
1. Wrap two layers of Teflon tape on vacuum generators inlet fitting threads and install into the 90
0
elbow
located in the ORION-2D manifold body. Turn until the inlet fitting is snug and the vacuum generators
largest side is parrallel to the manifold’s side.
2. Turn the 90
0
elbow fitting 1/4 turn clockwise so that the vacuum generator’s exhaust port points to the
VENT valve.
3. Install the ORION-2D manifold onto front panel as described in Section 4.2.8 on page 19.
NOTE: Install the muffler and long nipple into the vacuum generator’s exhaust port prior to installing the two manifold
mounting screws.
4. Fill the cylinder to approximately 1000 PSIG and check all fittings for leaks. If there are no leaks, fill
nitrogen supply cylinder to maximum pressure. See Section 2.1 on page 4 for cylinder refilling
procedure.
5. Install panel/chassis assembly in its enclosure as described in Section 4.2.1 on page 14
