1.3 Placing the system in service
1. Verify that all vacuum sprinklers are set and that
inspector's test valve and/or piping auxiliary drain valves
are
CLOSED

the flow test valve.
9.
FULLY OPEN
the main water supply valve
(D1)
. Reset

all other valves are in their "normal" operating position
(refer to paragraph 2.2
NORMAL CONDITION
of the current
section for details).
11. Check and repair all leaks.
12. On new installation, system that has been placed out of
service, or where new equipment has been installed, trip
test the system to verify that all equipment functions
properly. Refer to paragraph 1.7.2
INSPECTIONS & TESTS
of the current section for instructions.
WARNING !
Performing a trip test will result in operation of
the deluge valve
(A1)
. Water will flow into the piping
network. Take necessary precautions to prevent damage.
