7/Service Checkout Procedure
Important:
This entire Service Checkout Procedure must
be performed in numerical order.
7.1 Set-up
1. Verify that there is 500 mmHg ± 10 mmHg (66.7 kPa
± 1.3 kPa) vacuum on the supply gauge.
2.
The supply open flow must be 80 L/min minimum.
3. Connect the supply vacuum to the adapter/
probe port.

7.2 Push-To-Set
TM
Test
1.
Connect the 10 L/min flowmeter to the patient port.
2. Move the mode selector switch to | (ON).
3. Set 200 mmHg (26.6 kPa) on the gauge and keep
the knob pushed in. For the pediatric unit set at 135
mmHg (18.0 kPa), for the neonatal unit set at 100
mmHg (13.3 kPa) and for the C.A.S.S. unit set at 140
mmHg (18.7 kPa)
4. Make certain leakage at the patient port connection is
no more than 1 L/min.
5.
While observing the flowmeter with the knob still
pushed in, rotate the knob. Leakage should be no
more than 1 L/min. Release the knob and move the
mode selector switch to O (OFF).
7.3 Gauge Test
Note:
Analog gauges are supplied with an accuracy
of ±5% of full scale deflection throughout their
range. See step 4 of Section 7.4 Regulation Test.
Note:
Digital gauges are supplied with an accuracy of
±1% of full range at 22
°
C.
Note:
All gauge needles should come to rest within
the zero range bracket or return to the stop pin
when no suction is being supplied. Gauges which
do not comply may be out of calibration. Digital
gauge should read “0” when no suction is applied.
No calibration required on digital gauges.
Note:
When checking the accuracy of the gauge on the
analog unit, be sure that the calibration gauge
has an accuracy of 1% of full scale deflection or
better.
7.3.1 High Vacuum Gauges ONLY
1.
Connect the regulator’s fitting/patient port to the high
calibration gauge with tubing.
2. Move the mode selector switch to | (ON).
3. Ensure that the gauge is in agreement with the high
vacuum calibration gauge within the ± 38 mmHg (±
5.1 kPa) tolerance. Recommended test points are
100, 300, and 450 mmHg (13.3, 40.0 and 60.0 kPa).
4. Push and rotate the suction control knob fully
clockwise and ensure that the vacuum calibration
gauge reads at least 450 mmHg (60.0 kPa).
5. Three mode models ONLY: Move the mode selector
switch to MAX and ensure that the vacuum calibration
gauge reads at least 450 mmHg (60.0 kPa).
6. Push and rotate the suction control knob fully
counter-clockwise (decrease) and verify the gauge
reading decreases to zero.
7.3.2 Standard and PED/NEO/C.A.S.S.
Vacuum Gauges ONLY
1.
Connect the regulator’s fitting/patient port to the low
calibration gauge with tubing.
2. Move the mode selector switch to | (ON).
3. Ensure that the gauge is in agreement with the
low vacuum calibration gauge within ± 10 mmHg
(± 1.3 kPa) for the standard model. For the PED/
NEO/C.A.S.S. models, ensure that the calibration
gauge is within ±8 mmHg (± 1.1 kPa). Recommended
