3.6 Installation

3.6.1 Connection to piping

Machines with oval flanges
Carry out the following operations to connect the machine to
piping:
- Unscrew the screws fastening the counterflanges to the
machines.
- Remove the two counterflanges
- Remove the two gaskets present between counterflanges and
machine base
- Brake the protecting central disks along the marked lines to get
two gaskets with central holes.
- Screw the two counterflanges at the threaded ends of the
piping.
- Position the machine so that the arrows on the base match the
fluid flow direction.
- Position the two circular gaskets between couterflanges and
machine
- Alternatively tighten the screws fastening the counterflanges to
the machine
correct
Machine with round flanges
Carry out the following operations to connect the machine to
piping:
- Fit two counterflanges having a size matching those of the
machine flanges to the pipe ends
- Remove the two protecting caps on the machine flanges
- Position the machine so that the arrows on its base match the
fluid flow direction
- Fit the two circular gaskets between counterflanges and flanges
- Fit the screws in the flange and counterflange holes
- Alternatively tighten the nuts on the screws
Counterflange

3.6.2 Terminal box position

Carry out the following operations to direct the terminal box in the
required position:
- Remove the connection covering grids
- Unscrew the assembly bolts of motor and machine body
- Rotate the motor of 90° or 180° or 270° (in relation to the initial
position)
- Screw the bolts alternatively and in a uniform way
- Refit the connection covering grids
