4.16 Leak Testing the System
Leak test the system before putting into operation.
1. Be sure that there is a valve in the downstream equipment to turn off the gas flow.
2. With the cylinder valve open, adjust the regulator to deliver the maximum required delivery flow rate.
3. Close the cylinder valve. Watch to see if the high pressure or contents gauge drops, if it does you have a leak in the con-
nection between the regulator and the cylinder.
4. Once leak testing has been performed and there are no leaks in the system, slowly open the cylinder valve and proceed.

WARNING
If a leak has been detected anywhere in the system, dis continue use and have the system repaired.
DO NOT use leaking equipment. Do not attempt to repair a leaking system while the system is under
pressure..
