Cylinder Leak Check
If a leak is suspected during the high-pressure leak test (see Section 3/Pre-Use Checkout; High Pressure
Leak Test), the following steps can be taken to check for leaks (see Figure 5-3 for possible cylinder gas leak
locations) in the INOMAX regulator or INOMAX cylinder.

1. Cylinder Valve Regulator Connection
2. INOMAX Regulator Hand Wheel Connection
3. Regulator End Cap Connection
4. Tamper Evident Tape
5. Valve Nut
6. Safety Pressure Release Device
1. Ensure that INOMAX regulator is connected to
cylinder valve outlet (hand-tighten only), that the
cylinder valve is open, and that the cylinder has
more than 14 bar (200 psig).
2. Apply soapy water to points 1, 2, 3, 5 and 6 (see
Figure 5-3); if bubbles form, there is a leak.
3. If there are no bubbles, leak may be inside
INOblender or INOmax DS
IR
and cannot be
repaired. Replace INOblender or INOmax DS
IR
and contact Customer Support.
Recommended actions should a leak be detected:
1. A leak detected at points 1 and 2 (see Figure
5-3) may be corrected by tightening the INOMAX
regulator hand wheel.
a. If cylinder valve is open, close cylinder valve
and tighten INOMAX regulator hand wheel.
b. Open cylinder valve and reapply soapy water
to points 1 and 2.
c. If bubbles form, there is a leak.
d. Remove INOMAX regulator and check white
plastic tip on INOMAX regulator for chips or
cracks. Replace if necessary (see replacing
the tip on the INOMAX regulator, page 16).
For the ISO type regulator connector, check
that the O-ring is present and is not damaged.
Replace if necessary (see replacing the
O-ring on the INOMAX regulator, page 17).
Repeat step b (note: If leak remains, replace
INOMAX regulator).
2. If a leak is detected between the regulator body
and regulator end cap (see point 3), replace
INOMAX regulator and contact Customer Support.
3. A leak detected at cylinder valve nut connection
(see point 5) may not be repaired.
Replace INOMAX cylinder and contact Customer
Support.
4. A leak detected at safety pressure release device
(see point 6) may not be repaired. Replace
INOMAX cylinder and contact Customer Support.
