3.6 Pipeline and cylinder tests
1. Connect the pipeline supplies one at a time and ensure that the
corresponding display indicates pipeline pressure.
2. Disconnect all pipeline supplies.
a. Open each cylinder valve.
b. Make sure that each cylinder has sufficient pressure. If not, close the
applicable cylinder valve and install a full cylinder.
3. Test the cylinder supplies for a high pressure leak. Make sure that each
cylinder has sufficient pressure:
a. If equipped, turn the auxiliary O
2
flow control fully clockwise (no flow).
b. If equipped, turn off venturi derived suction.
c. Open each cylinder.
d. Record the cylinder pressure.
e. Close each cylinder valve.
f. Record the cylinder pressure after one minute. If the pressure
decreases more than indicated below, there is a leak.
690 kPa (100 psig)
for all gases.
If a cylinder supply fails this test, install a new cylinder gasket and do
this step again.
4. Close all cylinder valves.

WARNING
Do not leave gas cylinder valves open if the pipeline supply is in use.
Cylinder supplies could be depleted, leaving an insufficient reserve
supply in case of pipeline failure
.
3.6.1 O
2
supply alarm test
1. Establish O
2
, Air, and (if equipped) N
2
0 gas supplies.
2. Set O
2
to 25% and (if equipped) N
2
0 as balance gas. For machines without
N
2
O, set Air as balance gas.
3. Set total flow to 3 L/min.
4. Stop the O
2
supply. (Disconnect the pipeline supply or close the cylinder
valve.)
5. Make sure that:
a. The low “O
2
supply pressure low” alarm occurs.
b. The N
2
O (if equipped) and O
2
flows stop.
c. Air (if selected) flow continues or an Air selection prompt appears.
6. Reconnect the O
2
supply.
