2-4.4 Discharge Indicator (Optional)
The discharge indicator (P/N 81-967082-000), may be installed in the discharge piping to vi-
sually indicate a system discharge. In the set position, the discharge indicator acts as a vent
allowing agent pressure that may have accumulated in the manifold (due to a leaking cylinder
valve) to vent to atmosphere.

2-4.5 3/4” Manifold Check Valves
Use the 3/4” Manifold Check Valve (P/N 38-400002-002) between the discharge hose and the
manifold. Manifold Check Valves are included with the pre-built manifolds available for pur-
chase and included in the flow calculation software.
Note: If creating a manifold using NPT tooling, use a 1” BSPT Female to 1” NPT Male adapter
that matches the pipe rating of the manifold.
