Maintenance Schedules
Maintenance Mode
Toggling the Maintenance Mode button will allow
testing and service to be performed on the manifold
without triggering alarm sent to the master panel.
Maintenance mode is automatically turned off after
15 minutes. A timer is shown near the button once it’s
activated. On the main screen, a yellow bar that reads
“IN MAINTENANCE MODE” displays on the top.
Regulator Settings
Once a year, check and verify regulator settings.
Line Regulator Switching
The line regulators should be alternated every 3
to 6 months. Alternate the regulators by manually
opening the valves directly upstream and downstream
of alternate regulator, then manually shutting off the
valves directly upstream and downstream of the current
active regulator. A bleed valve is located on the side of
each final line regulator to purge trapped gas.
Check for leaks semi-annually in all threaded fittings,
including pigtail connection to header, header union to
manifold, and high pressure relief valve.
Alarm set points, proper operation of changeover,
header shutoff valves should all be verified and/or
tested annually.
Pigtails are to be replaced every 5 years after date of
startup.
