Operation Procedure
The following instructions must be followed for all gasses except Nitrogen:
1. Make sure the lever is set to indicate the bank “In Use”.
2. The “In Use” regulator is set to 160 psi with the “Reserve” regulator set to 120 psi.
3. When the “In Use” side depletes pressure down to approximately 120 psi, the “Reserve” bank will take over and
start to supply gas.
4. The pressure switch is set to 140 psi decreasing pressure and will alarm when the “In Use” bank is depleted.
5. To switchover, simply move the lever from the depleted bank to the opposite bank to indicate the bank “In Use”.
This resets the pressure switch.
6. Now change the cylinders in the empty bank.
7. The system is now ready for the next switchover.
8. The normal pressure setting for the line regulators is 55 psi.
FOR NITROGEN MANIFOLDS:
The “In Use” regulator is set to 250 psi and the “Reserve” at 200 psi. The pressure switch should be set to 225 psi decreasing
pressure while the normal pressure setting for the line regulators shall be 170 psi.
