Never plug, obstruct or tamper with safety relief devices.
Wear safety glasses and ear protection when working with compressed gases.
Regulators for Compressed Gases
Use only the specified regulator for carrier and calibration gas. Confirm
regulator type and material with your specialty gas supplier.
Use the carrier gas filling station only for refilling the internal carrier
gas cylinder
( MX380303 or MX380323 for nitrogen; or MX380319 or
MX380325 for air) .
Mark each regulator with its intended service and never use a regulator for
more than one service. Do not change gas service, or adapt equipment without
consulting your gas supplier.
Ensure regulator construction materials are compatible with the gas, and that
the cylinder pressure gauge will withstand the cylinder pressure. A stainless
steel diaphragm is suggested as this will reduce the potential for the carrier gas
to be contaminated by the regulator itself.
Never use the regulator as a shut-off valve. Close the cylinder valve when it is
not in use.
Do not subject the regulator to an inlet pressure greater than recommended.
Do not move or detach the regulator when it is pressurized or when it is in use.
Before connection, ensure the cylinder valve and the regulator CGA connection
are clean.
When connecting a regulator to a large gas cylinder turn the valve on the
cylinder clockwise to close the cylinder. Turn the regulator off. Open the
cylinder valve slowly and check for leaks. Adjust the delivery pressure and
then open the regulator outlet valve.
