4. Use one of the 1/2 in. (13 mm) knockouts provided in
the top, bottom or side of the release enclosure to exit
the pipe and install balance of pipe, fittings and pressure
relief valve as shown in Figure 5. Wrench tighten all pipe
joints to prevent leakage of gas. All applications will
require an actuation line pressure relief device, such as
a line vent or pressure relief valve. The type of pressure
relief device used will be determined by the type of sup-
pression system. Refer to the Installation, Operation and
Maintenance Manual provided with the Ansul Fire
Suppression System for the correct actuation line vent
or pressure relief valve.

5. If remote manual cable pull station is to be installed,
complete the steps in the following section. Otherwise,
go to WIRING THE ANSUL AUTOMAN II-C RELEASE
on page 4.
REMOTE MANUAL PULL STATION INSTALLATION
(CABLE TYPE)
The remote pull station, (Part No. 4835) allows the ANSUL
AUTOMAN II-C to be manually actuated from some point
distant from the release. Refer to appropriate NFPA
Standards and the ADA (Americans with Disabilities Act) for
mounting guidelines.
1. Select location for mounting manual remote cable pull
station. (Pull station must be located within 100 feet
(30.5 m) of the release or as stated in the Installation,
Operation and Maintenance Manual provided with the
Ansul Fire Suppression System.)
2. Fasten 4 in. (102 mm) junction box (not furnished)
where pull station is to be mounted. (Position the junc-
tion box with printing right side up.)
3. Install and secure 1/2 in. (13 mm) rigid conduit from
ANSUL AUTOMAN II-C release assembly to pull station
using pulley elbows (Part No. 45771) for changes in
direction. (Do not use more than 8 pulley elbows
between the release and the pull station.)
4. Feed wire rope through pull station junction box and
conduit into release. Make sure wire rope rides on top of
and in center of pulley sheave. If the 50 ft. (15.2 m) wire
rope provided is not long enough, obtain wire rope (Part
No. 4595) and splice lengths with two sleeves (Part No.
4596). Do not allow wire rope splice to be within 12 in.
(30.5 cm) of any pulley elbow.
5. Fasten pull station assembly cover to junction box.
6. Thread wire rope through rear guide hole in manual trip
lever on release. See Figure 6.
7. Pull slack out of wire rope and thread end through
sleeve (Part No. 4596).
8. Loop the wire rope back up around and through top of
sleeve.
9. Position sleeve approximately 1/2 in. (13 mm) from trip
lever and crimp to secure wire rope.
10. Make certain ring pin is not installed in release puncture
pin assembly.
11. Remove red glass indicator rod from pull station by
removing set screws on side of stud and slide rod out.
12. Pull ring on pull station. If release mechanism is tripped
easily, pull station is properly installed. If release does
not trip easily, remove pulley covers and check to see
that wire rope is correctly positioned in pulley elbow
sheave.
13. Cut off excess wire rope 3/4 in. (19 mm) below sleeve
assembly.
14. Reinstall glass indicating rod.
15. Proceed to “WIRING THE ANSUL AUTOMAN II-C
RELEASE.”
