• If necessary mount valves before and after the pump. Do not use quick-acting valves,
as they may cause high pressure impulses in the pump and the piping (water hammer
pressure).
• Before installing the pump, all piping should be flushed, to eliminate all dirt, grease or
possible other particles.

Installing a CL pump

The pump can be mounted in both horizontal and vertical piping. However, the electric
motor should always be in horizontal position.
When installing this type of pump, proceed as follows:
1 Make sure the piping is supported before and after the pump (brackets).
2 The arrow on the pump casing shows the exact position of the suction and delivery
flange.
3 Check the position of the terminal box on the electric motor in relation to the position
of the pump in the piping. If this position is not correct, the stator should be rotated.
See paragraph 7.6.1 "Electric motor stator".
4 Mount the flange gaskets and place the pump between the flanges of the piping.
5 Insert the fastening bolts and nuts for each flange and tighten them crosswise.

Installing a CBH pump

When installing this type of pump, proceed as follows:
1 Mount the flange gaskets and place the pump between the flanges of the piping.
2 In case of permanent arrangement of the pump, level the pump on the foundation by
means of shims.
3 Then carefully tighten the nuts of the foundation bolts.
4 Insert the fastening bolts and nuts for each flange and tighten them crosswise.

Connecting the electric motor

The electric motor must be connected to the mains by an approved
electrician, according to the locally prevailing regulations of the electricity
company.
• Refer to the instruction manual belonging to the electric motor.
• If possible, mount a working switch as close as possible to the pump.
