Installing the GC
Attach valve actuator air (optional)
C A U T I O N

Valves are driven by air actuators. Valves should have a
dedicated air source; they cannot share detector air supplies.
Valve actuator air is supplied through 1/4-inch plastic tubing. If
your GC was ordered with valves, the plastic tubing will already
be attached to the actuators and will extend from the back of
the GC. Additional valves are shipped with a 1/4- to 1/8-inch
reducing union to be used in plumbing.
Route the tubing away from the oven exhaust. The hot air will melt the
plastic tubing.
Materials needed:
• 1/4-inch Swagelok fittings and front and back ferrule
• Two 9/16-inch wrenches
Turn the air off at the source. Use a sharp knife if you need to
shorten the tubing. Connect the tubing to the air source using a
1/4-inch
nut and ferrules. See
