CR/EN (1004) 4.0 Installation 23
CombiPro
• 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
ƽ 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.
