3.5 Piping
As regards the piping and connecting points of the pump attention should be paid to the
following:
• Preferably the pump should be mounted in the piping in such a way that the direction
of flow is vertical, so as to prevent air from remaining in the pump. Air in the pump may
cause damage to the mechanical seal!
• Make sure that the system has one or more draining apertures. Also, it should be
possible to bleed or de-aerate the system, preferably directly above the pump.
• 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.
3.6 Installation
The pump can be mounted in both horizontal and vertical piping.
If the pump is provided with an electric motor B3/B5 or B5 the electric motor must be
mounted in horizontal position.
If the pump is provided with an electric motor V1 the electric motor must be mounted in
vertical position.
When installing the 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 electric motor should be
rotated.
4 Mount the flange gaskets and place the pump between the flanges of the piping.
5 Insert the fastening bolts and nuts and tighten them crosswise.
3.7 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.
