4-3.14 Installation of Cable Operated Control Head,
P/N 979469
WARNING
!
The cable operated control head (P/N 979469)
must not be used with the stackable pressure
operated control head (P/N 878750). Installing
the cable operated control head on the
actuation port of the stackable pressure
operated control head will cause the device
to malfunction.
The following procedures must be performed before attach-
ing the control head to the cylinder valve.
1. Remove the protection cap from the cylinder
actuation port.
2. Remove the cover from the control head and
take out the wheel assembly, cable pipe locknut and
closure disc.
3. Make sure the plunger is below the surface of the
control head body. Position the control head at the
valve control port with the arrow pointing in the di-
rection of pull.
4. Assemble the cable pipe locknut to the cable pipe and
place the cable pipe in the control head body.
5. Slide the wheel assembly on the control cable to the
SET position. Tighten the set screws securely. Make
sure the wheel assembly is at the start of the stroke.
6. Cut off any excess control cable close to the
wheel assembly.
7. Insert the closure disc and replace the cover on the
control head. The control head is now armed.
CAUTION
!
To ensure the manual lever does not snag or
trap the cable, make sure the local manual
release lever is in the SET position with the
locking pin and seal wire installed before
assembling the control head cover to the body.
8. Assemble control head to cylinder valve actuation port.
Tighten swivel nut securely.
4-3.15 Installation of Lever Operated Control Head,
P/N 870652
1. Ensure the control head is in the SET position with the
safety pull pin and seal wire intact.
2. Remove the protection cap from the cylinder valve
actuation port.
3. Using a suitable wrench, assemble the control head
to the cylinder valve actuation port. Tighten the swivel
nut securely.
4-3.16 Installation of Nitrogen Cylinder, P/N 877940,
and Mounting Bracket, P/N 877845
1. Locate the nitrogen cylinder mounting bracket in an area
where the cylinder valve assembly and control head
will be protected from inclement weather by a suitable
total or partial enclosure, preferably adjacent to the
FM-200 storage cylinders.
2. Install the mounting bracket clamps and hardware.
Install the nitrogen cylinder in position in a mounting
bracket; tighten sufficiently to hold the cylinder in
place while allowing the cylinder enough free play to
be rotated.
3. Turn the cylinder until the cylinder valve discharge out-
let is in the desired position. The nitrogen cylinder must
be positioned so that control head is readily accessible
during manual operation.
4. Securely tighten the mounting bracket clamps
and hardware.
5. Attach the adapter (P/N 6992-0501) and connect the
nitrogen pilot lines.
6. Remove the protective cap from the cylinder valve
actuation port.
WARNING
!
Ensure the control head is in the SET position
(that is, the actuating pin is in the fully
retracted or SET position) before attaching
it to the cylinder valve. If the control head
is not in the SET position, FM-200 will
discharge accidentally.
7. Install the control head to the cylinder valve actuation
port and tighten securely.
4-3.17 Installation of Pressure Switch,
P/N 486536 and P/N 981332
WARNING
!
To prevent injury, de-energize all electrical
components before installing the pressure
switch.
Pressure switches must be connected to the discharge
manifold or piping in an upright position as shown on the
system drawings. Both the standard and explosion-proof
switches have 1/2-inch NPT pressure inlets to connect
to the system piping. The electrical connections are ei-
ther 1/2-inch conduit knockouts for the standard pres-
sure switch or 1-inch NPT fittings for the explosion-proof
pressure switch.
