5.2. Replacing the reduction inserts
•
Unscrew the mounted reduction inserts.
•
Screw the reduction inserts with the corresponding diameter into the clamping devices.
•
If necessary (e.g. for T- pieces) the outer fixed clamping device can be dismantled by
unscrewing the three hexagon socket screws.

5.2.1. Using small and large reduction inserts
Small reduction inserts:
•
Pipe fittings often have only a short straight surface area on which they can be clamped.
•
Fittings mostly need to be clamped in the inner clamping devices with the small reduction
inserts.
•
When fittings are to be welded (bends, T-pieces etc.), the inner small reduction insert can
also be used flush to the inside or to the outside.
