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 cylinder valve.
3. Pressure gauge should indicate > 14 bar
(200 psig).
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 5/ 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 (20 ppm when using a 400
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
(+ 2 sec.).
4. Continue purging until pressure gauge
reads zero.
Note: If the pressure does not decrease, then
the INOblender is not delivering NO and
the INOblender should be replaced.
