Marshall Excelsior Two-Stage Automatic Changeover Regulator
Operation:
Ensure that the regulator has been mounted with the vent pointing downward so that water or debris cannot gather in the regulator. Place one of the two cylinders in “primary” by switching the black changeover lever in the direction of the selected cylinder. The arrow on the lever will denote the “primary” side. Open both cylinder valves slowly. The indicator on the top of the regulator will turn green. The “primary” side of the regulator will continue to supply gas as long as sufficient gas is present in the “primary” cylinder. When the pressure in the cylinder drops below a designated pressure, the “reserve” side will open and continue to primary gas to the regulator. At the time that the “primary” cylinder becomes exhausted, the indicator on the changeover lever will turn red indicating a cylinder change can be made.
Cylinder Exchange:
Prior to removing the empty cylinder, position the black changeover lever so that it points to the alternate cylinder that is now supplying the regulator. Close the valve on the empty cylinder and remove. After the empty cylinder is refilled and reconnected, slowly open the cylinder valve. The new cylinder is now the reserve cylinder. The indicator at the top of the regulator will turn green.
