Plumbing the Purge Gas
QuickSwap Installation and Startup
7
5
Locate the external gas line hole on the left side of the GC (
).
6
There is a hole in the oven inside wall that lines up with the external gas
line access hole. Use a thin tool to make a hole through the insulation
connecting the two holes.
Do not use any of the tubing to make the hole
through the insulation.
7
Uncoil the purge gas tubing (Aux #5). Place a plastic cap or two thicknesses
of aluminum foil over the end of the tubing to keep insulation fragments
out. Push the capped tubing into the external hole and into the oven. Feed
enough tubing through the hole so that you can install a fitting on the end.
8
Remove the cap or foil and install the 1/8-inch to 1/16-inch reducing union
from the kit on the end of the tubing inside the oven.
WA R N I N G
The insulation around the oven is made of refractory ceramic fibers. To avoid inhaling
fiber particles, we recommend the following safety procedures: ventilate your work
area; wear long sleeves, gloves, safety glasses, and a disposable dust/mist respirator;
dispose of insulation in a sealed plastic bag; wash your hands with mild soap and cold
water after handling the insulation.
