page 2-5).
4. Perform a 40 cmH
2
O manual leak test. If present, set the left vaporizer to ON and perform a
40 cmH
2
O manual leak test. Set the vaporizer to OFF. Repeat for the right vaporizer if
installed (see “Manual Leak Test” on page 4-24).
5. Perform a vaporizer leak test for each vaporizer installed on the A7 System (see “Vaporizer
Leak Test” on page 4-24).
6. Check that AGSS float moves freely. Set the vacuum flow so that the float position is
between the Min and Max lines (see “Inspect the Active AGSS” on page 4-30).
7. Drain any moisture from the breathing system water trap and the condensation drain valve
at the bottom of the absorber canister assembly.
Prior to each patient, before administering anesthesia, the following should be done:
1. Inspect the A7 for damage or hazardous conditions; check all necessary equipment and
supplies are present, e.g., drugs, CO

absorbent (not exhausted), breathing circuits and tank
wrench.
2. Check that central supply O

, N
2
O and Air pressures are each within the pipeline input range
specifications (i.e., 40 to 87 psi).
3. Perform the flow control system test (see “Flow Control System Test” on page 4-22).
4. Perform a vaporizer leak test for each vaporizer installed on the A7 System (see “Vaporizer
Leak Test” on page 4-24).
5. Verify that Auxiliary O

8. Check that valves on the O
2
, N
2
O, and Air cylinders (if present) are closed until needed to
prevent unintentional use of gas.
9. With a breathing circuit and reservoir bag attached, check that the unidirectional valves
operate by visual inspection.
10. Check ventilation capability in Standby, Manual, VCV and PCV ventilator modes.
11. Check that patient suction is adequate to clear the airway.
12. Verify ability of required monitors and check alarms.
The following step is recommended to be performed weekly, whenever a new vaporizer is
