SECTION 8 – MAINTENANCE EXAMINATION

R-102 Restaurant Fire Suppression Manual
The maintenance information listed in this section deals with
the limitations and parameters of this pre-engineered system.
Those individuals responsible for the maintenance of the R-102
system must be trained and hold a current ANSUL certificate in
an R-102 training program.
Maintenance is required semi-annually. At the 12 year interval,
along with the normal maintenance exam, the tank(s) must be
hydro-tested and the regulator(s) must be flow tested.
Prior to performing the required maintenance steps, verify that
the R-102 system protection is designed and installed correctly
for the existing appliance and ventilation system configuration. If
not, make corrections as required.
SEMI-ANNUAL MAINTENANCE EXAMINATION
Semi-annual maintenance procedures for single, double, and
multiple-tank systems are as follows.
NOTICE
Under certain circumstances hood and
duct cleaning operations may render the
fire suppression system ineffective due to a
coating of cleaning chemical left on the detec-
tion equipment or mishandling of the system
by cleaning service personnel. Therefore, it
is strongly recommended that the R-102
system be completely inspected and
serviced by an authorized ANSUL distribu-
tor immediately following any such clean-
ing operations.
1.
Remove the enclosure cover from the AUTOMAN
regulated release assembly and each regulated actuator
assembly.
2. Insert the lock bar (Part No. 14985) or lock pin (Part No.
438031) on the cocked regulated release mechanism. See
Figure 8-1 or Figure 8-2.

3. Remove cartridge from regulated release assembly and
each regulated actuator assembly, install safety shipping
cap, and set aside in a safe location.
4. Check to make certain the actuation line used to connect
the regulated actuator assembly(s) to the AUTOMAN regu-
lated release assembly is connected to the high pressure
side (right side) of the cartridge receiver in the AUTOMAN
and that it is intact, with all fittings securely tightened. This
includes any 1/8 in. copper tubing and fittings used to
connect to the air cylinder for the ANSUL mechanical gas
valve.
CAUTION
If the actuation line leaks pressure, the regulated actuator
assembly(s) may not operate. A severe leak can render
the entire system inoperable.
5. To check for leaks in the actuation line, a hand held or
electric vacuum pump may be used:
a. Disconnect the actuation line from the AUTOMAN regu-
lated release cartridge receiver and connect the pump to
the line.
b. The pump should pull a vacuum to 20 inches of mercury,
as shown on the gauge. Leaks should not exceed 5
inches of mercury loss within a 30 second time frame.
c. If the gauge indicates a leak in the line, examine for
loose connections or damage. Repair or replace as
needed.
d. If leakage is not due to piping, disassemble the pneu-
matic actuator assembly(s) in the regulated actuator(s)
and inspect the actuator and the o-ring in the actuator.
Repair or replace as needed.
Note: Vacuum pumps can be obtained from automotive
parts/supply stores.
