8. Applicable Anesthetics and emergency drugs are available.
9. The casters are not damaged or loose and the brakes are set and function correctly.
10. Make sure the breathing system is locked in position.
11. The AC main indicator and the battery indicator come on when the power cord is connected to
an AC power source. Note that if the indicators are not on, the system does not have electrical
power.
12. The anesthetic machine is switched on or off normally.
4.3 Flow Control System Test
1. Connect the central pipeline gas supply.
2. Clockwise turn the flow control (minimum flow).
3. Turn on the system switch to
position.
4. Test the O
2
-N
2
O Link system with flow increasing:
Turn the N
2
O and O
2
flow controls fully clockwise (minimum flow). Then turn the N
2
O flow control
counterclockwise and set the N
2
O flow control to the rates shown in the table. The O
2
flow must
meet the requirement listed in the following table.

flow to 6 L/min
respectively. Then slowly turn the O

O flow must drop to 0 L/min.
2. Set the system switch to
position.
