Connect the gas supply to the power supply using an inert-gas hose with a 3/8 inch (9.5 mm) internal diameter and a
1/4 NPT quick-disconnect coupler, or a 1/4 NPT x G-1/4 BSPP (CE units) quick-disconnect coupler.
WARNING
Do not allow the gas supply pressure to exceed 135 psi (9.3 bar). The filter bowl may explode if this
pressure is exceeded.
The recommended inlet pressure while gas
