ANNUAL MAINTENANCE EXAMINATION (Continued)
General (Continued)
8. Check condition of all actuators by completing the fol-
lowing:
a. Remove all actuators from the cylinders and leave
them off until the final step in the Maintenance
Section.
b. For manual actuators, check the condition of each
actuator to make certain they operate freely. When
finished, reset them and seal with inspection seals
as required. Do not install on cylinder valves.
c. For electric actuators, check to make certain all
wires are properly connected. Do not install on cylin-
der valves.
9. Check the condition of the orifice union and make cer-
tain correct size orifice plate is in place. Orifice size can
be read on exposed tab.
10. Check all pressure switches for signs of damage or cor-
rosion. Make cer tain piping to switch is properly
attached.
11. Check all switches on the system to assure they will
operate properly. These may include maintenance
switches, abort switches, main/reserve switches, etc.
When completed, make certain they are all set in the
correct position.
NOTICE
Before proceeding with Step No. 12, make
certain all electrical actuators have been
removed from all cylinder valves and that
the cartridge has been removed from the
ANSUL AUTOMAN II-C releasing
device(s) if part of the system.
12. Check condition of control panel for tampering, corro-
sion, or damage. Test panel at this point by referring to
the appropriate AUTOPULSE Control System Manual.
13. Check all detectors. Make certain they are in place,
clean, and not damaged. If required, check the sensitiv-
ity of each per the instructions of the detector manufac-
turer. See appropriate AUTOPULSE Control System
Manual for detailed operating instructions of the panel.
14. Check all pull stations. Make certain they are in place,
that they are not blocked or damaged. Operate each
pull station to make certain that they operate the control
panel. Reset each pull station and seal with visual
inspection seal.
15. While checking the detectors and electric pull stations,
inspect each alarm device. Check the alarms condition
and verify that it operates properly when energized.
Reset the alarm circuit after each test.
16. If the system includes an ANSUL AUTOMAN II-C
releasing device, test it per the instructions titled
Thermal Detection/Electric ANSUL AUTOMAN II-C
Release listed in this section. If system contains a cable
pull station, check it for correct operation at this time.
Reset and reseal after operating.
17. Reset the entire system. This includes the control
panel, all actuators, detectors, alarms, actuator car-
tridge, release cartridge, and pressure switches. After
all components have been reset, install actuators back
on to the cylinder valves.
18. Record that the maintenance has been performed as
required by the Authority Having Jurisdiction. Notify all
personnel that the maintenance has been completed
and the system is back to normal.
