NOTE
This cylinder mounting procedure will be typical for either nitrous oxide or oxygen cylinders.
CAUTION

Do not attempt to assemble nitrous oxide cylinder to oxygen yoke or oxygen cylinder to
nitrous oxide yoke.

Do not remove pins from yoke assembly.

Use “E” or “D” size cylinders only.
1. Rotate the tee handle screw clamp in a counter-clockwise direction until the point of the screw is
flush with the inside edge of the yoke bar.
2. Remove the cylinder seal from the captive strap on the cylinder. Dispose of the captive strap.
3. Place the cylinder seal on the cylinder seat such that gas nipple goes through the hole in the
center of the cylinder seal. See Figure 23.
4.
Locate the “E” cylinder directly underneath the cylinder with the cylinder shut-off valve located
towards the cylinder yoke and such that the face of the cylinder valve will face the face of the
yoke. See Figure 23 and 24.
5. Lift the cylinder shut-off valve through the yoke block and align the yoke pins with the pin holes
and the gas nipple with the cylinder port.
6. Move the cylinder towards the face of the yoke so that the pins and gas nipple engage with the pin
holes and cylinder port.
7. Rotate the Tee handle screw clamp clockwise until the point on the screw engages the
countersink on cylinder shut-off valve post.
8. Hand tighten (do not use tools) the tee handle screw clamp until it is very tight.
