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