3.3.1 Gas Connections—Control Unit
The only gas connection made to the Control Unit is the pressure
compensation line extending between the Analysis unit and the Control
Unit. A 1/8 inch tube fitting is installed on the rear panel for this purpose.
To connect the pressure compensation line:
1. Insert the 1/8 inch tube into the fitting and finger -tighten the
nut where the tube cannot be rotated freely. Tighten the nut an
additional 1/8 turn beyond finger-tight.
2. Use a wrench to hold the fitting body and keep it from turning
while you tighten the nut using another wrench When
assembling new fittings for the first time: Tighten the nut 1 ¼
turns.
