IMPORTANT:
Male sure you have installed the proper regulator on the working gas cylinder
and on the regeneration gas cylinder, connected tubing of sufficient length, and ensured
that there are no leaks.
The fittings for both gases are located on the rear wall of the gas purifier module. Connect the
working gas to the appropriately-labeled compression fitting and tighten it 1.25 turns from
finger tight. Over tightening compression fittings can cause problems.
