3.3 Mechanical installation of KPL and
KWM
Observe the maximum cable bending radius, see
11.2.1 Bending radius of cables .
Prior to installation, check the oil level in the oil
chamber. See section
9.2.3 Checking and changing
the oil .
Take particular care when installing the pumps, as
the procedure is not similar to that of other
submersible pumps. Make sure that the pump is
aligned with the anti-rotation brackets and in such a
way that pump rotation is prevented when the
impeller is running.
3.3.1 Requirement for free space below the pump
Measure the column pipe diameter,
∅
D, and find the
minimum value for free space below the pump (Min.
C) in the following table. See fig.
11 and fig. 12 .
