Perform the following Liquid Leak Detector Test (Section 3.2.1) to determine if there
are any substantial leaks. After performing this procedure, if you feel there is an
unacceptable amount of leakage, perform the Pressure Hold Test (Section 3.2.2) to
determine if the total leak rate is acceptable.

Liquid Leak Detector Test
PROCEDURE
1. Set the flow control valve to 0 L/min (off).
2.
Warm, Empty Unit:
Pressurize the Companion 1000/T Portable to approximately
22 psig (152 kPa) with gaseous oxygen using the portable pressurizing setup and
gaseous oxygen supply (Figure 3-1). Close the vent valve after pressurizing the unit
and remove the pressurizing setup from the vent tube.
