CAUTION: Use only one cylinder gasket per yoke. Use of more than
one gasket could cause leakage of the cylinder gas.
2. Before installing a cylinder:
a. Remove the cylinder dust cap, if present.
b. Briefly open then immediately close the cylinder valve to blow
any foreign matter out of the valve outlet. Do not use excessive
force on the shut off valve.
3. Install the cylinder valve over the strainer nipple, making sure that
the safety index pins are engaged.
4. Swing the gate closed in a clockwise direction and tighten the Tee
Handle sufficiently (by hand only) to hold the cylinder firmly in place.
Do not use wrenches or any other tool on the Tee Handle screws.
5. If only one oxygen cylinder is used, a yoke plug (Ohmeda Stock No.
6600-0399-500) and a gasket are required to seal the unused yoke
cylinder port.
CAUTION: Yoke check valves are not intended to provide a leak
free seal; always use a yoke plug and a fresh cylinder gasket to
seal an unused cylinder port.
6. Open cylinder valve S-L-O-W-L-Y, and rotate until it is fully open.
CAUTION: Open cylinder valves S-L-O-W-L-Y to avoid damaging
the regulators.

system(s) should be checked for leaks according to the following proce-
dure:
1. Discontinue use of the system to be tested.
2. Disconnect all pipeline gas supply and outlet lines from the yoke
assembly.
