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 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.
Note 3:
Water Pressure Regulator No. 8-6118 is recommended to ensure
proper water pressure.
For filtering, a coalescing filter able to filter to 0.01 microns should be installed as close as
possible to the gas inlets on the Gas Control Module.
Maximum Input Pressure 135 psi (9.3 bar)
