32. Remove outer oil plug with a 5/16" hex-key wrench then
remove inner oil plug with a 1/4" hex-key wrench.
33. Pour 1 bottle of Mueller hydrant lubricant into oil reservoir
until the bottle is empty or the oil is level with inner oil plug
hole. [Do not pour oil outside the oil reservoir].
34. Insert Inner oil plug (Smaller) inside the bonnet and tighten
to 5-10 ft-lbs with a 1/4" hex-key wrench. [Take care to avoid
damaging the bonnet paint with the wrench].
35. Insert outer oil plug (Larger) into bonnet and tighten to
5-10 ft-lbs with a 5/16˝ hex-key wrench. Do not overtighten
outer plug as it could deform the bonnet (Outer oil plug
should have two threads visible). [Take care to avoid
damaging the bonnet paint with the wrench].
36. Rotate operating nut to ensure the main valve is closed.
Turn ON water from gate valve.
37. With a minimum of 20 psi pressure, the sensor will come
online. At this point the new stem is communicating to the
new bonnet. Swipe the commissioning tool again at the
location in the ˝Signal Strength˝ section to fully commission
bonnet. The "success" / confirmation email and/or text may
take up to 5 minutes to arrive (See Appendix A). If feedback
does not come, swipe the commissioning tool again. If there is
no response 5 minutes after the second attempt, reconfirm:
a) Hydrant main valve is CLOSED
b) Gate valve is OPEN
c) Water has been drained below the antenna near the top
of the lower stem (Necessary for the stem to
communicate with the bonnet)
d) System water pressure is 20 psi or greater.
e) Re-swipe the commissioning tool.
If "success" feedback is not received within 5 minutes,
contact Customer Service. (Once a Sentryx software enabled
Super Centurion has been successfully installed, auto-locating
of hydrant using GPS will automatically begin. Device location
can take up to 72 hours to complete.)
38. Unscrew one hose nozzle cap slightly to bleed air.
Open hydrant fully.
39. Tighten hose nozzle cap when water starts flowing and check
all flange connections for leaks.
40. Turn operating nut in closing direction to make sure main valve
is fully closed, then turn in opening direction approximately 1/4
turn to relieve tension on operating mechanism. Remove hose
cap to aid in the draining of the hydrant. (Draining hydrants
only). After hydrant is drained, replace and tighten hose cap.
CAUTION
ALWAYS FILL THE OIL RESERVOIR WITH THE BONNET
INSTALLED, THE HYDRANT IN ITS NORMAL UPRIGHT
POSITION, AND THE MAIN VALVE FULLY CLOSED.
FILLING THE HYDRANT WITH OIL UNDER ANY OTHER
CIRCUMSTANCES CAN RESULT IN OVERFILLING AND CREATE
A PRESSURE LOCK. THIS COULD DAMAGE THE SEALS OR
BONNET OR PREVENT PROPER HYDRANT OPERATION.
CAUTION
DO NOT EXCEED 290PSIG ON PRESSURE SENSOR. IN
THE EVENT THAT THE SYSTEM PRESSURE WERE TO
EXCEED 290PSIG, ACCORDING TO THE MANUFACTURER’S
SPECIFICATION, THE SENSOR MAY ENDURE OVERPRESSURES
UP TO 420PSIG; HOWEVER, THE SENSOR WILL ONLY RECORD
PRESSURES UP TO 290PSIG.
