K. MULTIGAS OPTION
The Multigas option enables you to use multiple gases with the AccuPyc without having to
disconnect and reconnect each time you wish to use a different gas. The Multigas option con-
nects to the gas inlet on the rear panel of the AccuPyc, providing connections for up to four
gases.
The Multigas option consists of the following:
• valve assembly and two retaining screws
• gas entrance tubing for connection from the analyzer to the valve assembly
• gas supply tubing for four gases
Installing the Multigas Assembly
1. Remove the two retaining screws on the right side of the rear panel of the AccuPyc.
2. Position the valve assembly against the rear panel so that the retaining screw holes on the
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. Do not use the retaining screws you removed from the analyzer (step 1); they are not
long enough to hold the assembly in place.
4. Cut and remove the cable ties holding the gas entrance tubing in position; this will allow
flexibility for connecting to the analyzer.
If you currently have a gas attached to the gas inlet on the rear panel of the analyzer,
close the gas bottle valve and remove the inlet tubing from the analyzer before you
begin installation. You can reattach the gas to one of the inlet valves on the assembly.
