Primary Regulator Settings (CC & Models)
Note: All settings done with full cylinder pressure and with
slight gas flow thru the manifold. DISS demand valves have been provided on the line regulators and may be used
to create a slight flow. Primary regulator outlet pressure will vary with varying inlet pressures. (The outlet
pressure will rise as the cylinder pressure decreases).
