• Sudden changes in the rate of flow can lead to high pressure impulses in the pump
and the piping (water shock). Therefore, do not use quick-acting closing devices,
valves etc.
3.6 Accessories
• Fit any parts that may have been supplied separately.
• If the liquid does not flow towards the pump, fit a foot valve at the bottom of the
suction pipe. If necessary, combine this foot valve with a suction strainer to prevent
impurities from being drawn in.
• When mounting, place temporarily (for the first 24 operating hours) a fine gauze
between suction flange and suction pipe to prevent internal pump parts from being
damaged by foreign matter. If the risk of damage continues to exist, fit a permanent
filter.
• In case the pump is provided with a cooling chamber, connect the cooling chamber to
the supply and return lines of the cooling system.
3.7 Connection of 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, fit a working switch as close as possible to the pump.
