26 Installation and Operations Manual
28. Lower the tape cable to the tank bottom and let several inches fall on the tank bottom.
29. Temporarily attach the tape/cable to the float with the furnished fastener (see Figure 7 on
page 16). Feed the other end of the indicator cable over the sheave in the elbow and make
sure that it is seated on the pulley. Final attachment to be made at initial calibration.
30. Check the indicator tape/cable path between the float and the gaugeboard to be sure that
the tape/cable is not kinked or twisted. Also check the float guide cables for kinks.
31. Make certain that the float guide cables are parallel.
32. Slip the indicator over the gaugeboard.
33. Put the cable crimp (see Figure 9) on the end of the cable, then thread the cable through
the hole in the tank. Loop the cable on the outside back through the cable crimp and tem -
porarily tape it to the crimp.
Note If auxiliary equipment is to be installed, do it prior to crimping the cable connector.
The use of auxiliary units not manufactured or supplied by Varec will void any Varec war -
ranty and will relieve Varec of any obligation to service the product under warranty.
34. Tape the gaugeboard indicator to the gaugeboard at 2.00 inches [50.8 mm] to hold it in
place. Adjust the cable tension until the float barely lifts off the tank floor, then crimp the
cable connector and remove the tape.
Note As the float is four inches [101.6 mm] high and its waterline is at its equator, it can -
not register the last two inches [50.8 mm] of liquid in the tank.
35. Tie a line longer than the height of the tank to the indicator.
Caution Do not allow the float to fall back to the floor of the tank. Damage may result.
36. Slowly pull down on the indicator and lift the float to the top of the tank. Travel should not
produce noticeable binding. Slowly lower the float to the floor of the tank.
37. Remove the pull line.
