*Review the Seat Wrench Operating Manual (F14285) for more seat ring removal information. For complete Sentryx software enabled Super Centurion It is just as important to confirm the location's signal strength prior to installing a complete Sentryx software enabled Super Centurion. However, the bonnet will already be installed on the hydrant. Please reference the Mueller Cellular Signal Strength guide (F14334) for suggestions on how this can be accomplished. HYDRANT FLUSHING Depending on the location of the hydrant, conditions of piping, hydrant lateral, etc. prior to de-pressurization it is recommended to flush the hydrant until water is clear prior to the insertion of Sentryx software enabled Super Centurion parts. DE-PRESSURIZATION OF HYDRANT WARNING DO NOT REMOVE ANY BOLT(S) HOLDING THE HYDRANT TOGETHER BEFORE THE HYDRANT IS DE-PRESSURIZED. DISASSEMBLY OF HYDRANT WITH PRESSURIZED WATER ACTING AGAINST THE MAIN VALVE COULD RESULT IN EJECTION OF HYDRANT PARTS AND DEBRIS, 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 DE-PRESSURIZED BEFORE DISASSEMBLY AND DOES NOT INADVERTENTLY GET RE-PRESSURIZED. Before removing any bolt(s) holding hydrant together, shut off the appropriate gate or isolation valve(s) to isolate hydrant from 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. 3. Open hydrant main valve completely. 4. 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. 1. 2. 2 2 INSTRUCTIONS FOR SENTRYX SOFTWARE ENABLED SUPER CENTURION:

The following instructions apply to the installation of the Sentryx software enabled Retrofit Kit. For the complete hydrant, install the same way as a Super Centurion Fire Hydrant
