Transport

Step 1: Locate your gas cylinder from the gas cylinder cage and transport to the lab with the use of a gas cylinder cart.

B: Make sure the cylinder is properly secured to the cart before

Step 2: Make sure the cylinder is properly secured to the cart before transporting.

C: Secure the cylinder in the lab, to the wall or bench with a

Step 3: Secure the cylinder in the lab, to the wall or bench with a gas cylinder clamp. Important: 1 metal chain for 1 gas cylinder. Do not secure multiple gas cylinders with 1 chain. Have a minimum distance of 1.5 m between two incompatible gases such as H2 and Air.

Connect gas regulator

A: Undo the cap and screw on the appropriate regulator for the gas.

Step 4: Undo the cap and screw on the appropriate regulator for the gas.

B 5: Use a proper regulator wrench to tighten the regulator.

Step 5: Use a proper regulator wrench to tighten the regulator. Do not over tighten and do not use adjustable wrench. Do not use Teflon tape on the cylinder connections.

C: Check that the flow control valve is closed.

Step 6: Check that the flow control valve is closed.

Check pressure and valves

Step 7: Turn the pressure adjusting screw on the regulator counterclockwise until it turns freely.

A: Slowly open the cylinder valve. A ½ turn is usually sufficient.

Step 8: Slowly open the cylinder valve. One full turn is usually sufficient.

C: Check the gas cylinder pressure gauge. A full cylinder has

Step 9: Check the gas cylinder pressure gauge. A full cylinder has approx. 2200 psi except for acetylene, carbon dioxide or special gas mixtures.

Check pressure and leak test

Step 10: Turn the pressure adjusting screw clockwise until the required pressure is reached (gauge further from the gas cylinder valve).

Step 11: Check for gas leaks by using Snoop(TM) on all the threaded connections including the cylinder valve.

Step 12: If all is correct, control the gas flow by the flow control valve on the regulator. Do not use the pressure adjusting screw for flow control.
