Figure 5. – Fixing Ratchet Strainer to Aircraft Cable
6. The other end of the Aircraft Cable is now
ready to be fixed, however, the cable will have
to be tightened or tensioned to prevent the
atomization line from sagging and to create
the necessary drainage gradient. To do this a
ratchet tightener must be installed in the line.
7. To install the ratchet tightener, use the short
length of Aircraft Cable supplied with the
ratchet and form a loop by running the short
length of cable through the eyelet, around the
post and secure with two crimp sleeves. Next,
run the end of the support Aircraft Cable
through the revolving pin taking up as much
slack as possible. Then, secure using one
crimp sleeve.
8. Using a wrench, twist the revolving pin to take
up the remaining slack in the support Aircraft
Cable. Keep twisting until the Aircraft Cable is tight and does not sag. Make sure that the Aircraft Cable is
straight and is not being deflected by other object.
9. Unroll the atomization line on the ground below the Aircraft Cable. Do not allow the atomization line to become
excessively dirty and make sure the protective caps on the end of the nozzles and lines remain in place. While
on the ground, it may be convenient to align the nozzles into the desired position; however, this is reasonably
straightforward to do when the line is suspended.
10. Take one end of the atomization line and using zip ties (part# ACT0009); attach the complete line to the cable
loosely. Connect atomization line to manifold line. Proceed from this point working your way to the end of the
atomization line tightening the zip ties and orientating the nozzles to your preferred spray direction. Attach zip
ties to atomization line at a distance of no more than 12” (300mm). Please refer to figure 7 on page 12. Zip tie
lock clip should be mounted away from Aircraft Cable. This will attach atomization line to cable securely.
11. When finished the atomization line should be suspended as illustrated in figure 8.
