The following tests must be done with a minimum supply vacuum of -53 kPa (-400 mmHg):
1. Move the selector switch to the "OFF" position. Turn the regulator knob one complete turn in the clockwise
direction. Kink the vacuum tubing to block the outlet. There should be no movement of the gauge needle (or in
case of a digital gauge, no change in display).
2. Move the selector switch to the "REG" position. Turn the regulator knob fully in the counter-clockwise
direction. Kink the vacuum tubing; again, there should be no movement of the gauge needle (or in case of a
digital gauge, no change in display).
3. Kink vacuum tubing.
Regulator Setting:
Standard:
Pediatric & Neonatal:
4. Open and close the kinked vacuum tubing slowly to reach various vacuum rates. Ensure that the level of vacuum
maintains consistently when the vacuum tubing is kinked.
Standard Continuous and High Vacuum: Follow the steps below based on mode type
2 Mode:
5. Decrease the vacuum to zero and move the selector switch to the "OFF" position.
3 Mode:
5. Move the selector switch to the "FULL" position. Kink the vacuum tubing and ensure that the vacuum gauge
is reflecting the maximum suction available.
5b. Move the selector switch to the "REG" position.
5c. Decrease the vacuum to zero and move the selector switch to the "OFF" position.
Continuous Intermittent Vacuum:
6. Move the selector switch to "INT".
7. Kink vacuum tubing.
8. Timing cycles are approximately 16 seconds on and 8 seconds off.
NOTE: The intermittent unit starts in the off cycle.
NOTE: Timing is preset at factory using a source vacuum level of 500 mmHg (66.7 kPa).
9. Decrease the vacuum level to zero and move the selector switch to the "OFF" position.
Pediatric & Neonatal:
10. In the "REG" position, kink the vacuum tubing and turn the regulator control knob fully in the clockwise
direction to ensure that the vacuum level does not go over -21 kPa (-160 mmHg) for Pediatric and -13 kPa
(-100 mmHg) for Neonatal.
NOTE: This feature is only present in the Pediatric and Neonatal models.
11. Decrease the vacuum level to zero and move the selector switch to the "OFF" position.
WARNING: Always verify vacuum setting prior to performing any procedure. Vacuum levels set in the "REG"
mode will remain the same when switched to the "INT" mode; and vacuum levels set in the "INT"
mode will remain the same when switched to the "REG" mode.
CAUTION:
When the collection canister is full DO NOT operate the Vacuum Regulator. The WARRANTY WILL BE
VOIDED if the canister overflows and contaminates the Vacuum Regulator.
Amvex Vacuum Regulator Operating & Maintenance Manual
Increase the vacuum to -12 kPa (-90 mmHg)
Increase the vacuum to -5 kPa (-40 mmHg)
Timing may vary in relation to the source vacuum pressure.
