For complete Smart Hydrant Solutions , It is just as important to confirm the location’s signal strength prior to installing a complete Smart Hydrant Solutions Super Centurion. However, the Pumper Cap Assembly will already be installed on the hydrant.

HYDRANT FLUSHING

• Depending on the location of the hydrant, the conditions of piping, hydrant lateral, etc. prior to depressurization it is recommended to flush the hydrant until water is clear prior to the insertion of the Smart Hydrant.
DE-PRESSURIZATION OF HYDRANT
WARNING
DO NOT REMOVE ANY BOLT(S) HOLDING THE HYDRANT TOGETHER BEFORE THE HYDRANT IS DE-PRESSURIZED.
DISASSEMBLY OF A HYDRANT WITH PRESSURIZED WATER ACTING AGAINST THE MAIN VALVE COULD RESULT IN THE EJECTION OF HYDRANT PARTS AND DEBRIS, A HIGH-PRESSURE WATER STREAM, OR OTHER DANGEROUS CONDITIONS THAT COULD CAUSE SERIOUS BODILY INJURY OR DEATH.
FOLLOW ALL COMPANY POLICIES AND OSHA REQUIREMENTS FOR LOCK-OUT/TAG-OUT TO ENSURE THE HYDRANT IS DEPRESSURIZED BEFORE DISASSEMBLY AND DOES NOT INADVERTENTLY GET REPRESSURIZED.

Before removing any bolt(s) holding the hydrant together, shut off the appropriate gate or isolation valve(s) to isolate the hydrant from the main water source.
Loosen – BUT DO NOT REMOVE – one nozzle cap two turns and check for water under pressure inside the hydrant – bleed off any pressure, then remove the nozzle cap completely.
Open the hydrant main valve completely.
A continuous flow of water, no matter how slight, indicates hydrant is not properly isolated from the main water supply. This issue must be corrected before any hydrant disassembly can proceed, i.e. the water to the hydrant MUST be stopped.

Remove the pumper cap and install the new Pumper Cap Assembly.
Rotate the operating nut to ensure the main valve is closed. Turn on the water from the gate valve.

Activate Smart Hydrant on Sentry

With a minimum of 20 psi pressure, the sensor will come online. At this point, the new stem is communicating to the new Pump Cap Assembly using the radio internal to the Hydrant (2.4Ghz).
Open the Smart Hydrant App. Click on Activate and follow the steps on the screen.
Hold the phone near the location in the picture below.
The “success” / confirmation email and/or text may take up to 5 minutes to arrive. If feedback does not come, complete the activation steps again. If there is no response 5 minutes after the second attempt, confirm:
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 Pumper Cap Assembly)
d) System water pressure is 20 psi or greater.
e) Retry Step 3.
If “success” feedback is not received within 5 minutes, contact Customer Service. (Once the installation has been completed, auto-locating of the hydrant using GPS will automatically begin. Device location can take up to 72 hours to complete.)
Unscrew one hose nozzle cap slightly to bleed air. Open the hydrant fully.
Tighten the hose nozzle cap when water starts flowing and check all flange connections for leaks.
Turn the operating nut in the closing direction to make sure the main valve is fully closed, then turn in an opening direction approximately ¼” turn to relieve tension on the operating mechanism. Remove the hose cap to aid in the draining of the hydrant. (Draining hydrants only). After the hydrant is drained, replace, and tighten the hose cap.
At this point, the Smart Hydrant has been successfully installed. The Smart Hydrant will take the pressure and temperature readings and transmit them over a cellular network. Please adjust settings as needed on the Sentry web interface.

CAUTION
DO NOT EXCEED 290PSIG ON THE PRESSURE SENSOR. IN THE EVENT THAT THE SYSTEM PRESSURE WAS 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.
