Note 1: The air source must be adequately fi ltered to remove all oil or grease. Oil or grease
contamination from compressed or bottled air can cause fi res in conjunction with oxygen.
For fi ltering, a coalescing fi lter able to fi lter to 0.01 microns should be placed as close as
possible to the gas inlets on the Gas Control Module.
Note 2: The tap water source does not need to be deionized, but in water systems with extremely high mineral content a water softener
is recommended. Tap water with high levels of particulate matter must be fi ltered.
