Personal injury or death can result from improper accumulator charging.Dry nitrogen is the only gas approved for use in the accumulator.

Do not use color codes or other methods of identification to tell the difference between nitrogen and oxygen cylinders.Never use an adapter to connect your nitrogen charging group to a valve outlet used on both nitrogen, oxygen or other gas cylinders. Be sure you use dry nitrogen (99.8 % purity).
