How to install gas cylinders (high-pressure leak test)
Cylinder yokes1. Find the cylinder wrench.
2. Close the cylinder valve on the cylinder to be replaced.
3. Fully loosen the tee handle.
4. Open the cylinder yoke.
5. Remove the used cylinder and the used gasket.
6. Remove the cap from the cylinder valve on the new cylinder.
7. Point the cylinder valve away from all flammable items and items that can 
be damaged by a release of pressure.
8. Quickly open and close the cylinder valve. This removes dirt from the 
cylinder outlet.

No gasket or more than one gasket can cause a leak. 
9. Install a new gasket.
10.Align the cylinder post with the index pins.
11.Close the yoke gate and tighten the tee handle.
12.Install a cylinder plug and gasket in all empty cylinder yokes.
13.Do a high-pressure leak test:
•Disconnect pipeline supplies.
•Disconnect all equipment from the pneumatic outlet and turn Off the 
auxiliary flowmeter.
•Set the system switch to Standby.
•Open the cylinder.
•Record the cylinder pressure.
•Close the cylinder. 
•If the cylinder pressure decreases more than 690 kPa in one minute, 
there is a leak.
To repair a leak:
•Install a new cylinder gasket and tighten the tee handle.
•Do this step again. If the leak continues, do not use the system.

2. Loosen the adapter and remove the cylinder.
3. Remove the cap from the cylinder valve on the new cylinder.
4. Point the cylinder outlet away from all items that can be damaged by a 
release of high-pressure gas.

5. Open and immediately close the cylinder valve to remove dirt or contaminants.
6. Do a high pressure leak test:
•Disconnect pipeline supplies.
•Disconnect all equipment from the pneumatic outlet and turn Off the 
auxiliary flowmeter.
•Set the system switch to Standby.
•Open the cylinder.
•Record the cylinder pressure.
•Close the cylinder. 
•If the cylinder pressure decreases more than 690 kPa in one minute, 
there is a leak.
To repair a leak:
•Tighten the cylinder connection.
•Do this step again. If the leak continues, do not use the system.
