Instructions for Setting the Intermittent Timing
1. Turn over the Vacuum Regulator so that you are looking at the back of the unit.
2. Connect the Rear Port of the Vacuum Regulator to a Vacuum Source.
3. Occlude the Bottom Port.
4. Switch the Vacuum Regulator to INT mode.
5. The unit will begin in the OFF phase of the
intermittent cycle. To increase the off time, turn
the OFF needle valve clockwise using a slotted
screwdriver. To decrease the off time, turn the OFF
needle valve counterclockwise.
6. To increase the on time, turn the ON needle
valve clockwise using a slotted screwdriver. To
decrease the on time, turn the ON needle valve
counterclockwise (see Figure 1).
CAUTION: Do not continue to turn the needles
once resistance is felt. Doing so could damage
the Vacuum Regulator.
For Pediatric and Neonatal Regulators only:
e. In the REG position, kink the vacuum tubing and turn the Regulator 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. The Vacuum Regulator
is equipped with a Safety Relief Valve that triggers and emits an audible vibration
once the maximum allowable vacuum is reached. To reset the Safety Relief Valve, turn
the Regulator Knob counterclockwise to reduce the vacuum level. If the Safety Relief
Valve fails to trigger when the maximum allowable vacuum is reached, do not use the
Vacuum Regulator and contact your service provider.
NOTE: This feature is only present for the Pediatric and Neonatal models.
For Sentinel Regulators only:
f. On the back side of the Vacuum Regulator, press the TEST button using the test tool
and hold for 1 second. The Amber BATT LED will light up. This indicates that the
batteries are not dead. If the Red CHECK LED doesn’t turn on, this means that the unit
is not contaminated.
NOTE: This feature is only present for the Sentinel models.
NOTE: Amico Patient Care Corporation recommends that the user complete the Procedures Prior to
Use (pages 5-6) to ensure that the Vacuum Regulator is operating correctly.
