tube life.
701RE and 701REX LoadSure tube element loading
700 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 delivery (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.
