12-YEAR MAINTENANCE EXAMINATION
In addition to performing all of the steps necessary for semi-an-
nual and annual maintenance, the following twelve-year mainte-
nance procedures for single, double, and multiple-tank systems
must be performed.
NOTICE
Under certain circumstances hood and duct
cleaning operations may render your 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
distributor immediately following any
such cleaning operations.
At twelve-year intervals, the liquid agent
tank(s) must be hydrostatically tested and
refilled with a fresh charge of ANSULEX
Low pH Liquid Fire Suppressant. The date of
manufacture is stamped on the bottom of the
agent tank or on the tank label.

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
