High-Pressure Leak Test
1. Make sure NO dose setting dial is turned to
zero and flow meter is OFF.
2. Open and then close the INOMAX cylinder
valve.
3. Check the INOMAX drug cylinders for the
correct product identity, cylinder concentration,
and expiration date. Verify cylinder has at
least 500 psig (replace if 200 psig or less), and
tighten the fitting to the INOMAX cylinder.
4. Monitor pressure gauge for 30 seconds for
any signs of pressure decrease. If no pressure
decrease is observed, high-pressure leak test
successful, proceed to Delivery Confirmation
and Purge.
5. If observed pressure decrease continues, see
Section 7/ Maintenance; Cylinder Leak Check.
6. If leak cannot be traced, replace the
INOblender.

Delivery Confirmation and Purge
1. Set the INOblender to 40 ppm when using an
800 ppm cylinder.
2. Set the oxygen flow on the INOblender flow
meter to 10 L/min to begin purge.
3. Ensure the pressure gauge decreases
approximately 14 bar (200 psig) in 10 seconds
(+ two seconds).
4. Continue purging until pressure gauge
reads zero.

the INOblender is not delivering NO and
the INOblender should be replaced.
