5. Check N
2
O, O
2
and AIR Lines for leaks.
a.
Remove the cylinders from the
.
b.
Connect the O
2
, AIR and N
2
O hoses to the gas line inlets.
NOTE:
If a specific gas source is not available, skip the
corresponding leak test.
c.
Verify O
2
, AIR and N
2
O Line Pressure gauges read the corresponding line pressure.
d.
Set the AIR flow controller to minimum.
e.
Pinch to occlude the O
2
, AIR and N
2
O hoses.
f.
Disconnect each hose from its line pressure source.
g.
Verify that the pressures do not drop more than 2 psi over a time period of 20
seconds.
6. Verify that all available line and cylinder gauges are operational.
a.
Connect the O
2
supply hose and remove the AIR and N
2
O hoses.
b.
Verify the O
2
Line Pressure gauge shows the reading of the line pressure.
c.
Connect the AIR supply hose and remove the O
2
and N
2
O hoses.
d.
Verify that the AIR Line Pressure gauges show the reading of the line pressure.
e.
Connect the O
2
and N
2
O hoses and remove the AIR hose.
f.
Verify that the N
2
O and O
2
Line Pressure gauge shows the reading of the line
pressure.
g.
Attach the cylinders to the
's yokes (O
2
and N
2
O or AIR). In the case
where multiple cylinders of the same gas are required, attach one at a time.
h.
Open all attached cylinders including the O
2
cylinder. If a cylinders pressure is less
than 500 psi, replace the respective cylinder.
i.
Verify that the cylinder pressure gauges register a pressure for each type of gas
attached.
7. Test O
2
Flush operation with only O
2
connected.
a.
Connect the O
2
supply hose and remove the AIR and N
2
O hoses.
b.
Attach a calibrated flow meter to the Common Gas Outlet.
c.
Push the O
2
Flush button and verify a reading between 35 L/min and 50 L/min at
the flow meter.
NOTE:
O
2
flow may be greater than 50 L/min at higher altitudes.
d.
Reconnect the O
2
, AIR and N
2
O hoses.
8. Test the O
2
:N
2
O ratio system (applicable to -01 units only).
a.
Set all flow control knobs to minimum.
b.
Increase the flow of N
2
O until the O
2
reaches 1 L/min
c.
Verify that the N
2
O flow is not higher than 3.7 L/min.
d.
Return flow control knobs to minimum.
