Testing the GSS-4PM
35.
Ensure that bypass valve C is closed (
Figure 2
or
Figure 3
).
36.
Close the product inlet valve on the sample cylinder.
37.
Actuate the GSS-4PM.
38.
Observe the sample outlet pressure gauge (
Figure 2
or
Figure 3
). Allow pressure to build above line pressure, and then
let the GSS-4PM sit for several minutes.
39.
After several minutes, read the pressure on the sample outlet pressure gauge. If the pressure has dropped, check the
GSS-4PM for leaks and repair as necessary. If the pressure has not dropped, the unit is ready to be placed into
operation.
40.
Bleed off the test pressure from the sample cylinder.
41.
Open the product inlet valve on the sample cylinder.
Preparing for Sampling
42.
Set the signal control system to the desired sampling frequency based on the sampling actuation equations provided
(
Figure 7
). If the GSS-4PM is equipped with a 4P, refer to the
Installation, Operation, and Maintenance
(IOM)
Manual
for
the 4P for instructions on setting the sampling frequency. If the GSS-4PM is equipped with a 6Tc, refer to the
Installation, Operation, and Maintenance
(IOM)
Manual
for the 6Tc for instructions on setting the sampling frequency.

Note that the sample volume of the Vanishing Chamber™ collection cup could be 0.065 cc, 0.22 cc, 0.5 cc, 1.0 cc, or 1.5 cc.
43.
The GSS-4PM is now operational.
