Follow these procedures:
1. Make sure all piping connections are
in accordance with The Chlorine
Manual or local procedures. The CGA
820 yoke and adapter assembly is the
standard connection used to connect
process tubing to the cylinder valve
outlet.
Always install a new gasket
between the valve face and the
CGA 820 yoke connection each
time the connection is made.
2. Tightening the yoke bolt (in picture) will
compress the
gasket and secure
the yoke rigidly to
the valve by
coupling the valve
outlet flange to the
process tubing or
piping with a CGA
820 connection.
3. After checking for leaks at the connections, and
with the valve opened no more than one (1) full
turn of the valve stem, the
Ter minator Actuator
can now be placed on the valve.
4. Remove the retention pin that
extends through the end of both
rods of the actuator.
5. Align the actuator shaft and
drive bushing with the valve
stem. With the actuator rods
parallel to the sides of the valve, let the actuator
slide down on the valve while rotating the drive
bushing by hand to
align the bushing
with the flats on the
valve stem (Fig. 1)
6. The drive bushing
should fully engage
the wrench flats on
the valve stem.
7. The Terminator Actuator mounting rods are
designed to straddle and loosely grasp the
valve on either side of the outlet as shown in
figure 2. The two rods on the actuator will fit
inside the standard
yoke and fit loosely
on either side of
the valve nozzle
after the drive
bushing is seated
as shown in
Figure 3.
8. Confirm proper
alignment of the
actuator and the
valve stem by
visually checking the actuator drive bushing and
valve shaft.
9. Reinstall the
retention pin.
When properly
installed, the pin
should slide just
under the valve
outlet and extend
through both rods.
With the pin in
place, the
Terminator
should not be able
to be lifted up and
off of the valve.
10. The Terminator
Actuator is
designed to fit
loosely and rest directly on the cylinder valve
stem. When activated, the actuator will make a
loud ratcheting noise and move around slightly
during the closing of the valve
.
11. The Terminator Actuator weighs about 8
pounds. Gravity, along with a secure fit on the
cylinder valve, will keep the actuator in place
during activation
. The retention pin provides
additional security.
12. Follow instructions for In-Service Testing in
Section VI, Page 8 - Placing System In
Operation.
