REQUIRED INTERNAL INSPECTION
The authority having jurisdiction in your area may have estab-
lished requirements for internal inspection frequencies. Verify
these requirements by contacting the authority having jurisdic-
tion in your area.
1.
Notify the authority having jurisdiction, remote station
alarm monitors, and those in the affected area that the system is
being taken out of service.
2.
Close the water supply’s main control valve (2) to take the
system out of service.
3.
Open the system main-drain valve (4) to drain any water
that has accumulated and to release system air pressure.
NOTE:
If the system has operated, open the remote system test
valve (inspector’s test connection) and any auxiliary drain
valves.
4.
Confirm that no water is flowing from the system main-
drain valve (4).
5.
Close the piston charge line ball valve (8).
6.
Close the slow-fill ball valve on the air maintenance device

If pressure still remains in the piston charge line (11),
make sure the auto drain knob (12) is in the “down” position. If
necessary, push down on the auto drain knob (12) to remove
pressure in the piston charge line (11).
