INSTALLATION
4.1 Open body model (PV)
Fig. 4.
The sleeve has not been designed to withstand axial forces.
The pipes must therefore be supported properly so that
neither tension nor compression is caused. Use cross-
tightening for flange bolts. Do not overtighten bolts.
Make sure that no inappropriate items get between the
pinch bars and the sleeve.
If possible, protect the sleeve from direct sunlight. Direct
sunlight and UV light deteriorate certain rubber qualities;
this must also be considered during normal use.
A lengthwise angle deviation of max. 5º in the pipe is allowed (Fig. 5).
Fig. 5. Fig. 6.
Deviation in the center line of the pipe (C), (Fig. 6):
PV 80…100 max. 5 mm
PV 125...250 max.10 mm
PV 300…500 max. 15 mm
PV 550…1000 max. 20 mm
