REV LEVEL B
Assemblies may include a speed control (black in color) which is located between
the Fire solenoid body (red anodize) and the manifold adapter (gold anodize).
This is used to slow opening time of the assembly when moving to the "Fire"
position. It has no impact on closing time. Factory setting prior to shipment is full
open. Speed adjustments are made using a small flat blade screwdriver. The
adjustment screw is located on the top end surface of the plate.
Model T1005: Solenoid operated pilot valves are momentary contact type. As
such, upon loss of pneumatic supply pressure or electrical power,
the system will hold last position for some period of time.
Model T1006 & T1007:
Solenoid operated pilot valves are maintained
contact spring return type. As such, upon loss of pneumatic supply
pressure or electrical power, the system will fail in the closed
position.
Model T1008: Fire solenoid operated pilot valves are momentary contact type.
As such, upon loss of pneumatic supply pressure or electrical
power, the system will hold last position for some period of time.
Purge solenoid operated pilot valves are maintained contact spring
return type. As such, upon loss of pneumatic supply pressure or
electrical power, the system will fail in the closed position.

INSTALLATION
WARNING
Prior to installation and/or start-up, inlet piping should be verified as
being free of dirt, grit, welding slag, or other particulate contamination.
Failure to do so may result in damage to valve internals.
A.
Unpacking
Do not remove protective plugs from valve and solenoid until ready to install. If
plastic protective caps are missing, verify no debris or foreign objects are inside
valve.
Transporting - Use proper hoisting procedures to avoid damage to valve. Do not
lift by conduit, switches, etc.
Purge all air lines prior to connecting solenoids.
