OPERATING INSTRUCTIONS
Inspect the gas cylinder valve for leaks before putting it into service. If a leak is found around the cylinder
valve stem, close the valve, place the cylinder outdoors in a safe area and inform your gas supplier
immediately.
Connecting The Regulator To A Cylinder
1. Chain or secure the cylinder to a wall, stand or cart. Remov e the p rotective dust cover from the
cylinder valve. Keep this cover and reinstall it on the cylinder valve if the Gas Regulator is removed and
the cylinder is to be used again.
2. Purge the cylinder valve of foreign materials by opening and closing it.
3. a. If the Gas Regulator has a yoke type inlet connection, be sure that sealing washer is in pl ace on t he
Gas Regulator yoke connection. Place t h e two pins on the Gas Regulator yoke int o the matching holes
on the cylinder valve. Be sure that the pointed end of regulator screws fits into the small round recess
on the side of the gas cylinder valve. Hand tighten the T-handle.
b. If the Gas Regulator has a CGA 540 connection, install the inlet nut on the cylinder valve and tighten
with a wrench.
c. If the Gas Regulator has a Bullnose or DIN inlet nut 477 connection, install the inlet nut on the cyli nder
valve and hand tighten.
ATTENTION: Sealing washers should be checked for damage or contamination before each use. I f
either is visible, rep lace immediately. It is recommended that a new seal be used each
time the cylinder is changed.
ATTENTION: Fittings attached to auxiliary ports are factory set to ensure proper flow. If user attaches
additional fittings to the auxiliary port, care must be taken to ensure factory sett ing is
maintained, by holding factory fittings in place with a wrench to keep it from rotating.
Flow should be verified whenever changes are made.
Setup For Use
1. Be sure the Gas Regulator is in the “OFF” position by rotating the knob counterclockwise to the “0”
position.
2. Stand so that the cylinder valve is between you and the Gas Regulator.
WARNING: Never stand in front or behind a Gas Regulator when opening the cylinder valve. Always stand
so that the cylinder is between you and the Gas Regulator.
3. Open the cylinder valve very SLOWLY, about one full turn counter clockwise.
4. If you detect a hissing sound, there is a leak in the system. Turn the cylinder off and turn the Gas
Regulator on. This will relieve any built up pressure. Try tig ht eni ng the Gas Regulator to the cylinder
GR-C-MANUAL (Rev. 1) 2017-11

and opening the cylinder again. If this does not help, shut the system down again and contact a
service representative.
5. Adjust the flow rate setting by turning the knob clockwise until the desired setting shows through the
window.
WARNING: NEVER try to remove the Gas Regulator unless the cylinder is off and pressure has been
relieved.
WARNING: If at any time the Gas Regulator, cylinder or other apparatus does not operate in its usual or
normal manner, stop using the apparatus and notify your dealer immediately.
WARNING: There is no flow between increm en ts.
ATTENTION: Flow rates are not accurate when a back-pressure of more than 2 PSIG exists downstream of
the Gas Regulator.
Closing The Regulator
1. When you have finished using oxygen, close the system by turning the cylinder valve clockwise to the
“OFF” position.
CAUTION: Oxygen will continue to flow from the outlet orifice assembly until the cylinder valve is
closed (Reference CGA Pamph l et P-14, “Accident Prevention in Oxygen Rich and Oxygen
Deficient Atmospheres”). It is very important to always close the cylinder valve when not in
use.
Removing The Regulator From A Cylinder
1. Close the cylinder va lve.
2. Wait for the oxygen to flow out of the Gas Regulator, then turn the knob to the “OFF” p osition
3. Remove the Gas Regulator from the cylinder by loosening the T-handle or removing the inlet nut.
4. When not attached to a cylinder, store the Gas Regulator in its original container in a clean protected
area free from grease, oil and other contamination.
5. Amvex recommends replacing the sealing washer on Yoke style inlet connection when the Gas
Regulator is mounted to a different cylinder.
CLEANING INSTRUC TIONS
Clean the external surfaces of the Gas Regulator with a damp cloth. If more cleaning is required, return the
Gas Regulator to your dealer.
CAUTION: DO NOT submerse the Gas Regulator in any form of liquid. This will cause damage and
void any warranty on the product.
