FIELD WORK

For Retroﬁt Kit

• Signal Strength:

– Prior to disassembly of installed hydrant, conﬁrm cell coverage at

site of installation.

– Hold the new bonnet near the same height and location of

installation.

– Place the commissioning tool close to the bonnet, approximately

1/4˝ away, above ˝M˝ on the seal plate ﬂange, while keeping away

from iron parts. (Reference to the right ).

– Move the commissioning tool up along the curve of the bonnet

keeping it approximately 1/4˝ away from the surface. This action

will cause the bonnet to awaken and search for a connection.

 If the bonnet does not establish a connection (i.e. no Sentryx

alert is provided within 5 minutes), select a diﬀerent location.

– Once a connection is established, the Sentryx platform will

send out an email and/or text message (Depending on initial

conﬁguration) displaying the signal strength. See Appendix A.

 If message indicates a weak signal, select a diﬀerent location.

 If message indicates a strong signal, proceed through

instructions below.

CAUTION

COMPLY WITH ALL REQUIRED INDUSTRY, SITE, STATE, AND

FEDERAL SAFETY REQUIREMENTS

DO NOT DROP NEW HYDRANT LOWER STEM OR NEW

BONNET ASSEMBLY. DAMAGE MAY OCCUR.

THE ANTENNA ON THE STEM CAN BE DAMAGED BY A

FORCEFUL IMPACT FROM A SEAT WRENCH – UTILIZE CARE.

SENTRYX SOFTWARE ENABLED SUPER CENTURION

IS DESIGNED TO WORK WITH MUELLER OEM PARTS ONLY.

AVOID BACKFILLING OVER EXPOSED BONNET AS DAMAGE

TO PAINT MAY OCCUR

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

1. Before removing any bolt(s) holding hydrant together,

shut oﬀ the appropriate gate or isolation valve(s) to isolate

hydrant from main water source.

2. 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.
