LoadSure tube element loading
720 series LoadSure tube elements: remove the chance of premature tube failure
caused by incorrect tube loading; avoid over-clamping of tubing; remove the need
to re-tension the tubing; extend tube life; reduce maintenance time for tube
changeover and cleaning; offer standard industrial tube connections.
Loosen the track-compression spring knobs using a 10mm A/F spanner, turning
them anticlockwise six (6) times.
Unscrew the track-securing bolt and withdraw the bolt fully. Lift the track by its
handle and slide it out from under the springs.
Locate the D-shaped flange fitted to the end of the tube element into the deliv-
ery (right-hand) sliding tube clamp. (The D flange ensures that the element can
only be loaded correctly.)
Slip the right-hand end of the track under the springs.
Locate the second D-shaped flange into the suction (left-hand) sliding tube
clamp. (Lifting the sliding tube clamp will aid the tube-loading.)
Position the left-hand end of the track so that the track-securing bolt can be
inserted.
Tighten the track-securing bolt with the 6mm Allen key provided.
Tighten both the track-compression spring knobs to a torque of 3Nm (2.2 lb-ft)
using a 10mm A/F spanner.
Connect both ends of the element to the rest of the system using industrial-
standard cam and groove connectors.
