TEE PIECE FOR HOSE CONNECTIONS,
P/N 38-509816-001
The tee piece is supplied with each of the completer kits.
It provides the interface with the pilot assembly (through
a high pressure flex hose) to simultaneously operate the
slave cylinder pneumatically.

BLEEDER VALVE FOR ACTUATOR,
P/N 38-509840-001
A bleeder valve is included with the Pilot Completer Kit to
prevent an accidental accumulation of pressure within
the pilot lines, which, if not bled to atmosphere, could
cause a false discharge. Connection requires a copper
gasket between the bleeder valve and pneumatic actua-
tor.
PILOT FLEX HOSES
This 1/4-inch ID reinforced rubber flex hose has threaded
connections to allow interface between components.

DISCHARGE FLEX HOSE, P/N 38-509819-001
This flex hose has 1/2-inch threaded connections to allow
interface between the cylinder valves and the discharge
manifold (if applicable). Where more than one cylinder is
connected to a common manifold, check valves are
required at the end of each discharge flex hose.

CHECK VALVE ASSEMBLY, P/N 38-509833-001
To prevent accidental discharge of the Argonite into unin-
tended areas, a check valve is required for each dis-
charge hose in all multi-cylinder systems. All Kidde Fire
Systems manifolds are constructed of threaded pipe with
welded check valve connections and include
pre-installed check valves. All customer connections are
via threaded pipe.
Note: For single cylinder systems, a 1/2-inch BSP x
1/2-inch FNPT adapter is required to connect the
discharge hose (BSP) to the Schedule 160 pipe
(NPT).
