10. The pressure monitor will begin
operating once the sensor cable
is plugged into the RTU and the
pressure sensor is exposed to line
pressure. The first reading may take
up to 24 hours to be transmitted to
the website. The Device will reveal
system pressures with no additional
inputs. In order to customize
4. After the drilling operation is
complete and corporation valve is
closed, apply a suitable sealant or
joint sealing tape on the inlet side
of the ¾” threads on the supplied
bushing. Securely attach the ¾” end
of the bushing to the outlet of the
corporation valve.
NOTE: Avoid use of excessive
sealant. Avoid contact with sensor
transducer tip.
5. Securely attach the pressure
sensor to the ¼” end of the bushing.
Utilize a suitable sealant or joint
sealing tape on the inlet threads
of the pressure sensor to ensure a
proper seal.
NOTE: Avoid use of excessive
sealant. Avoid contact with sensor
transducer tip.
6. Prior to installation of pressure
sensor dry the interior of the
corporation stop threaded
connection.
7. Once the sensor has been
attached, turn the corporation valve
to the “open” position. Run sensor
cable through composite valve box
when installing pressure sensor.
Refer to the installation instructions
for the Mueller
®
composite valve box
(Form MC014).
NOTE: When paving and
compacting asphalt, use a Mueller
iron lid (P/N: AJBV-4CWATER)
to prevent damage to the RTU.
Once asphalt work is completed,
replace iron lid with the RTU. Be
sure the sensor tip is exposed to
line pressure prior to connecting
the sensor cable to the RTU.
8. Once the corporation stop has
been opened and pressurized,
plug the male end of the multi-pin
connector of the sensor cable into
the mated connector of the RTU
(located on bottom of RTU).
9. Once the RTU and cable are
connected, insert the RTU into the
ductile iron top section.
NOTE: Be certain that the lid of
the RTU is mounted flush with the
surface of the ductile iron valve
box top section.

Warning High, Warning Low, Critical
High, and Critical Low. Entering the
above mentioned inputs into the
system is described in the “Getting
Started” on page 4.
