Ring, Sensor, and Special Installations 4-19
spaced every 46 to 61 cm (18 to 24 in.) from the bottom of the manhole to the
top.
Final Sensor Cable Preparation
l Neatly bind together all sensor cables leading away from the ring. Use cable
ties that are 20 cm (8 in.) long and 0.4 mm (0.14 in.) wide. Space the cable
ties 20 to 30 cm (8 to 12 in.) apart along sensor cables located within 1.5 m (5
ft) of the ring. The remaining length of cables should be secured at any interval
deemed appropriate by the field crew. Again, do not tighten the ties too much
and be sure to cut off all excess portions.
l Verify that the dryer tube on the pressure depth sensor's air hose points
downward. Secure it to the monitor.
l Ensure that the desiccant within the dryer tube is blue.
l Verify that the sensor cables are neatly coiled and installed in an orderly
manner. If not, disconnect the sensor cables from the monitor, repeat the
previous steps, then reconnect the sensor cables (page 4-15).
Note: Never coil the sensor cables with any other cabling. This could
compromise the IS of the installation.
