This is how the pump must stand in the sump
To attain maximum capacity and to prevent excessive wear, the pump should be positioned
in one of the following ways so that it doesn’t burrow itself into sand or clay.
This is how to install your pump
Connect the pump to power. If rotation of motor is wrong shift two phases.
(Shift two phases in the power supply terminal or in the CEE plug, or turn the knob on phase shifter).
If the pump still doesn’t start: Call a qualified electrician and ask him to check the mains and the junctions.
WARNING!
Swich off the current before installing or moving
the pump. Make sure that suspension brackets,
shackles and their means of attachment are undam-
aged. Before installing the pump attach a chain or
wire to the suspension bracket and use it to lower
the pump into the sump and lift it out again.
Place the pump on a firm base which prevents
it from sinking down or tilt over.
Hang the pump freely
by a chain or wire
Except for the pump the following
components are necessary:
1. Hose connection, which is fastened to the pump
2. Flexible hose
3. Lifting chain
Checkpoints before operating:
• Do not let the pump bury itself in the mud.
• Do not leave a large loop of the cable in the sump,
as the pump may eventually damage it.
• Check that the motor is adequately cooled. The
motorhousing should be at least 2/3 submerged
for continuous operation at full load (see Hmin.1 Fig.)
• It is good practice, whenever possible, to keep the
motorhousing completely under water.
• For choosing the discharge, pipe/hose inner diameter
to avoid sedimentation, the following minimum criti-
cal velocities can be used as a guide.
• Contaminated water containing fine sand, the velocity
should exceed 2,5 m/s.
• Water and larger solids in suspension, the velocity
should exceed 3,5 m/s.
WARNING!
Never use the cable for lifting or lowering the pump.
