NSTALL THE ULTIGAS
If a gas is attached to the gas inlet on the rear panel of the analyzer, close the gas cyl-
inder valve and remove the inlet tubing from the analyzer before installing the multigas
assembly. The gas can then be attached to one of the inlet valves on the assembly.
1. Remove the two retaining screws on the rear panel of the AccuPyc.
2. Position the valve assembly against the rear panel so that the retaining screw holes on the
valve assembly align with those on the rear panel of the analyzer.
3. Attach the valve assembly to the rear panel using the two screws included in the multigas kit.
4. Carefully cut and remove the cable ties holding the gas entrance tubing in position and remove
the ties.
5. Remove the protective caps from the ends of the gas entrance tubing, then remove the fer-
rules from the upper end of the tubing.
6. Remove the nut from the center port and slide it onto the end of the gas entrance tubing, then
replace the front and rear ferrules.
7. Insert the tubing into the center port of the multigas assembly. Use the nut to secure the tubing
to the assembly.
8. Insert the other end of the tubing into the gas inlet. Use the self contained swage nut to secure
the tubing to the inlet.
