Note 1: The air source must be adequately filtered to remove all oil or grease. Oil or grease
contamination from compressed or bottled air can cause fires in conjunction with oxygen.
For filtering, a coalescing filter able to filter 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 filtered.
Note 3: Water Pressure Regulator No. 8-6118 is recommended to ensure proper water pressure.
