2 2 1 2 Aligning the pipe ends Straighten out a length of approx. 1 m of the pipe, using a bending device if necessary. Fix the piping securely in place before fitting the connector assembly (e.g. on an assembly stand). Always use protective pipe clamping jaws when fixing the pipe in the vice. 120 mm Removal of the PE jacket Make a mark at a length of 120mm on the casing pipe. 3 4 Make a mark around the casing pipe using the protection cap as a guide. Cut radially using the saw. Attention: Take care not to cut the monitoring wires!

3 3 5 6 Cut the casing pipe longitudinally using the knife. Remove the casing pipe. 7 8 Remove the foam using the knife. Attention: Take care not to cut the monitoring wires. Bend the monitoring wires backwards.

4 mm 90 mm Make a mark on the corrugated pipe 90 mm from the end of pipe casing. Fit the clamp at the mark and check the distance at 3 points around the pipe Saw through the corrugated pipe using the face of the clamp as a guide. Insert a cloth and remove all burrs from the inside of the pipe.

5 Insert a cloth and remove all burrs from the outside of the pipe. Clean the outer surface using a stainless steel brush to remove all traces of insulation ~30 mm Remove the cloth and all shavings. Screw the internal backing sleeve (1) into the corrugated pipe. Approx. 30 mm of the internal backing sleeve must be left protruding from the end of the corrugated pipe.

6 ,5-2 mm Screw the thrust collar (4) onto the corrugated pipe, this must be screwed the full length of the internal thread and until it is tight. Push the connecting piece (3) right up against the internal backing sleeve (1). The distance between the connecting piece (3) and the thrust collar (4) must be 1,5-2 mm. You must screw the internal backing sleeve (1) in or out in order to achieve the gap 1,5-2 mm between the thrust collar (4) and connecting piece (3) Remove the connection piece (3) and push the graphite packing (2) in its whole length inside the gap between the internal backing sleeve (1) and the thrust collar (4). Push the connection piece (3) right up against the thrust collar (4) using the pre-installation bolts (13). Use grease or oil to prevent breakage of the pre-installation bolts.

7 Tighten the preinstallation bolts (13) until the permanent bolts (5) can be used. Replace all preinstallation bolts (13) with permanent bolts (5). Tighten all permanent bolts (5) clockwise. The connecting piece (3) and the thrust collar (4) must be bolted together until both flanges meet all the way round. If required: fit the o-ring (6) Push the connecting cable through its bore and connect it with the monitoring wires. Note seperate installation instruction. Grease the o-ring (6). Fit the protective cap (8) with a strong push until it makes contact with the beveled edge of the thrust collar (4).

8 8 25 Fix the protective cap (8) with its screws (7). Screw the connector for monitoring wires (11). If required: Fit shrink sleeve (9) half to half on casing pipe and protective cap (8). Note seperate installation instruction.
