2. Remove cartridge.
3. Remove ring pin and manually test system by operating
the remote manual pull station or push “STRIKE” button
on ANSUL AUTOMAN II-C release.
4. After operating manually, check that all functions have
been accomplished.
5. Cock ANSUL AUTOMAN II-C release mechanism using
cocking lever, Part No. 26310, and install ring pin.
6. Remove gasket from cartridge receiver in ANSUL
AUTOMAN II-C release mechanism. Check gasket for
elasticity or cuts and replace if necessary. Clean and
coat gasket lightly with a good grade of extreme tem-
perature grease such as Dow Corning No. 4. Reinstall
gasket into cartridge receiver. Do not install cartridge
at this time.
7. Make certain the release mechanism is cocked and ring
pin is removed.
8. Test each thermal detector by using an approved heat
lamp. Test each detector individually and recock release
mechanism after each test.
NOTICE
If system does not fire, check the integrity
of the solenoid by using an ohmmeter and
measure the resistance of the solenoid
coil. If it is not within the resistance range,
replace solenoid. There are two different
solenoids used in the ANSUL AUTOMAN
II-C release and their resistance is as fol-
lows:
