5. Turn on the system.
6. Set the system switch to On and set the Bag/Vent switch to Bag.
7. Set the flow controls to mid range of each flowtube.
Note If the system does not include N
2
O, skip steps 8 and 9.
8. Check the proportioning system concentration (increasing N
2
O
flow). Observe the following precautions:
• Start with all valves at the zero setting.
• Adjust only the N
2
O flow control.
• Increase the N
2
O flow as specified in the following table and
make sure the O
2
flow is as specified.
• If you overshoot a setting, turn the O
2
flow control clockwise
until the N
2
O flow decreases to the previous setting before
continuing the test.
9. Check the proportioning system concentration (decreasing O
2
flow). Observe the following precautions:
• Set the N
2
O flow to 9.0 L/min.
• Set the O
2
flow to 3.0 L/min or higher.
• While reducing the O
2
flow, set the N
2
O flow to the rates
shown in the table. The O
2
flow must be greater than the
minimum limits.
• If you overshoot a setting, turn the N
2
O flow control
counterclockwise until the O
2
flow increases to the previous
setting before continuing the test.
Set the N

O flow (L/min)
The O
2
flow must be greater
than (L/min)
