tail piece.
The 2 bushes are only required for trans­
port and are now no longer needed.
4 .2 Installation tailpiece and intermediate flange
• Ensure that the plastic shim plate (1) has been positioned on the
tail piece.
• Place one packing (2) between the tail piece and the tunnel.
• Apply a sealant (e.g. polyurethane or silicone) between the tail
piece and packing, and between the packing and the tunnel wall.
• Place the tail piece in the hole in the tunnel.
Any extra packings used should be ones capable of justifying the
tail piece.

flange. Fit the bolts.
• Now check size 'A' ('A' = 'B' + 8 mm ). Use the adjustable screw 'C' , if
