Maintenance of theElectronic
( EPC ) PressureControllers onSRI GCs
TheEPC solenoid ismounted on
the left side of theGC. A1/8”
Swagelok bulkhead fitting projects
through the left side of the chassis
where the gas is connected.
TheActual Pressuremight read
0.00 if the gas cylinder is not
turned on at all.
Verify that gas is arriving at the
EPC bulkhead fitting by loosening
the nut so you can hear the gas
hissing out. If you can not hear
the gas escaping then theremay
be a blockage between the gas
cylinder and theGC.
