amounts of tape (do not use cable ties). Pull the cable through the conduit to
the pavement box.
z Allow extra length on the communication cable so that the monitor can be
removed easily from the manhole for service.
Installing the Communication Cable Directly in the Ground
Install the direct burial communication cable in the following way:
z After the cement hardens, remove the protective tape and screw a plastic
bushing onto the rigid conduit.
Warning: Wire the communication cable to the DAA before mating the
communication cable connector to the QS3601 flow monitor.
z Find the trailing end of the communication cable (the end opposite the
connector). Push this end through the seal-off fitting, through the capped
elbow, and through the manhole wall.
Note: The instructions on the seal-off data sheet (included with the seal-off
fitting) must be followed exactly to maintain a Class I, Division 1, Groups C
and D rating for installation.
z Lay the cable in the trench between the manhole and the DAA. Back-fill the
trench carefully using clean fill dirt. Do not use rocks or any fill dirt that could
damage the cable during back-filling and tamping.
z To test the communication cable, attach the appropriate cable end to the
QS3601 flow monitor and to the DAA. If the cable has been installed
properly, you should be able to communicate with the monitor.
z Remove the close-up plug on the seal-off fitting. Follow the directions on the
seal-off data sheet included with the seal-off fitting. When completed, be sure
to replace the close-up plug on the seal-off fitting and to replace the cap on the
elbow.
z Alternatively, you can seal the conduit using expandable foam sealant (such as
Secofoam® made by Expandite) that can be purchased from building suppliers.
