Installing Cable
Speed Distance indicator:
This device will measure and display the distance traveled by the cable and also the speed at
which the cable is traveling. The functions are controlled by the small green push button on
the right of the display. If this button is depressed twice, the display will “toggle” between
speed and distance. Pressing the red button will reset the display to zero. Before starting an
installation, it will be necessary to depress the red button to set the distance display to zero.
Should it be necessary to replace the speed distance measuring indicator, it will be necessary
to reprogram it.
To install cable:
1. Attach drill to Whisper drive motor shaft (if not already attached) and tighten drill
chuck. Be sure that the drill is set in the forward or clockwise rotation setting and low speed.
2. Set drill torque setting starting at the minimum and work your way up.
3. Start air compressor and open air output valve, or if using nitrogen open the tank output
valve to full flow. Keep the valve on the Whisper closed.
4. Activate cordless drill to desired speed and monitor distance and speed with the counter.
Average installation speeds are between 150-300 FPM. It is sometimes necessary to gently
hand assist the fiber cable into the cartridge to initiate forward motion. (Do Not Bend or Over
Stress the cable.) When approximately 150’ of cable is installed, gradually open the air valve
on the Whisper
5. When cable exits duct end, take the desired amount of slack, stop drill and turn off air valve
and allow it to vent all the residual air before opening airbox.
6. Turn the power off on the counter to preserve battery life when not in use.
Caution: If during the installation, the cable hits an obstruction and stops, immediately
stop the drill. Continuing could severely damage the cable.
