Installation, removal and connection
Connecting the pump to the pipe system
1. Turn the pump shaft or fan impeller of the motor so that smooth running of the pump is checked.
If the pump cannot be turned by hand, remedy the fault before installing the pump, see "Trou-
bleshooting", page 32.
2. During welding work attach protective covers in front of the connecting flanges.
3. Place the piping in position and support the weight of the piping.
4. Check the clearance and the angular, vertical and linear offset, adjusting where necessary.
If the screws tighten easily, this is a sure sign that the installation is stress-free.
5. Tighten the connecting screws crosswise with torque, see Tab. 2, page 38.
