3. Cylinder Preparation: Remove any plastic wrap/washer from the top of cylinder.  Verify that the rubber washer (Fig. 3.2) provided with the E-Stand is still in place. Use the rubber E-Stand Gasket PN: A-3399-000 (replace once/yr.).

 

4. Mount the “E” cylinders of Oxygen and Nitrous Oxide (not included) to the E-Stand Block. Insert cylinders correctly on indexing pins and as marked on Block (N2O Figs. 3.1, 3.2;  O2 Figs. 3.3, 3.4). Pins assure mounting in appropriate position.

5. Slide the cylinder into place by lining up the pins and pin holes on the cylinder. Push into place. Properly placed, the cylinder should hang on the pins (Fig. 4).

 

6. Cylinders should hang freely between wheel base legs. If the wheel base interferes, loosen and rotate cylinder restraint or wheel base.

Troubleshooting the Attachment of Cylinders:
– New Gaskets P/N: A-3399-000 (Replace all 4 once a year).
– Tee Handle is pulled outwards and aligned.
– Swivel is parallel with E-Block. (See Fig 5.2)
– Bolt head not evident. (See Fig 5.3)
– Maintain aligned swivel position as Tee Handle is securely tightened.
