7.7.2 Patient Side
1. Connect the supply vacuum tubing to the adapter/
probe port.
2.
Connect the fitting/patient port to port “A” of the bubble
leak tester with tubing. Allow port “B” of the bubble leak
tester to be open to air.
3. Rotate the suction control knob a minimum of one full
turn clockwise (increase). No bubbles should appear
in the next ten seconds.
4. Rotate the suction control knob fully counter-clockwise
(decrease).
5. Move the mode selector switch to | (ON). No bubbles
should appear in the next ten seconds.
7.8 Flow Test
Note:
All PTS-CVR models should produce a minimum
of 25 L/min from the patient port given the following
conditions:
•
The supply open flow is 80 L/min minimum.
• The supply vacuum pressure is 500 mmHg ± 10
mmHg.
•
The unit has fittings on the fitting/patient
and adapter/probe ports with minimum inner
diameters of 0.140”.
• The unit is either directly connected to the vacuum
source, or connected with a tube no more than 4”
in length with a minimum inner diameter of 0.25”.
•
The unit is connected to a flowmeter with a tube
no more than 4” in length with a minimum inner
diameter of 0.25”

7/Service Checkout Procedure
• The unit is set to 100 mmHg ± 5 mmHg (12.7 kPa
± 0.7 kPa) in | (ON) mode.
• Adult/High models ONLY: the unit should
produce a minimum of 40 L/min at maximum
vacuum in | (ON) mode.
1.
Connect the fitting/patient port to the 50 L/min
flowmeter.
2. Move the mode selector switch to | (ON).
3. Set the unit to 100 mmHg ± 5 mmHg (12.7 kPa ± 0.7
kPa).
4. Release the suction control knob and verify that the
flow rate exceeds 25 L/min.
5. Adult models ONLY: Push and rotate the suction
control knob fully clockwise.
6. Release the suction control knob and verify that the
flow rate exceeds 40 L/min.
