OPERATING ALARM SYSTEMS
The manifold control cabinet contains the required circuitry to send a dry contact signal to the alarm unit when a
bank is empty and change-over occurs. The normally closed internal circuitry is designed to alarm when there is an

signal.
GAS SERVICE IDENTIFICATION
Amico manifolds are clearly labeled for the intended gas use, indicating the appropriate gas that is attached on the cabi-

HEADER BAR CONNECTIONS
The gas specifi c header bar should be attached to the In-let block on either side of the manifold. The In-let block is pro-
