included in this manual.
Note: See section 1, page 3, Illustration A & B
for component locations.
a) Daily Maintenance
1. Visually inspecting the red fire suppression
control head assembly, for set mode display
and pressure gauge to make sure the system
pressure is within proper range.
2. Visually inspecting the system detection
lines to make sure that the fusible links are
operational.
3. Inspecting all nozzles, keeping them free
from grease and assuring that all blow-off
covers are in place.
4. Determining that easy access to the manual
pull station can be made for manual
activation.
5. Assuring that good housekeeping practices
have been maintained to eliminate potential
fire hazards.
6. Visually inspect the fire damper and fusible
link for damage and operational readiness.
At this time, it is also good practice to visually
inspect all premises hand portable fire
extinguishers to verify good working condition.
b) Regular System Maintenance
To ensure the proper operation of the system,
regular inspection and maintenance must be
performed by certified personnel and on a semi-
annual basis, and after every periodic hood and

tested in accordance with the
recommendations of the manufacturer. The
hydrostatic testing of wet chemical
containers shall follow the applicable
procedures as outlined below.
4. The wet fire suppression systems shall be
tested, which shall include the operation of
the control head interlock mechanism and
