The total load on the wellhead foundation will
consist of the motor, pump bowl assembly,
riser pipe (full of water), wellhead assembly
and power cable. See Chapter 12.2 "Data
sheet", for weights.

2. Verify that open discharge run-off, ditch, etc.

for flushing out well and testing unit is pro-
vided for.

3. Verify that a log of the well recording depth,

straightness, casing variations, standing water
level, rated capacity, pumping level, etc., is at
the installation site.

Ensure that the well diameter is large enough
down to the installation depth so that the
pumping unit can be fitted without difficulties.
See Chapter 3.4.1 "Survey of well", Page 16.

5. Check the dependability of auxiliary equip-

ment, particularly of hoists.

6. Compare the information in Chapter

12.2

"Data sheet" with that on the rating plate on
the motor.

7. Ensure that the line voltage (measured be-

tween two phases) is equal to the motor volt-
age according to the rating plate.

The maximum permissible voltage fluctuation
is given in Chapter 12.2 "Data sheet".

Greater voltage and frequency fluctuations
must be reported to Flowserve and be con-
firmed by Flowserve in written. In case of
doubt, ask Flowserve before starting up the
pumping unit.

Measure the insulating resistance of the motor
according to Chapter 6.8.1 "Insulation test",
Page 53.

CAUTION If the ascending riser pipe is made

of flanged pipes, the flanges must
have recesses for the power cable if
the well diameter is narrowly pro-
portioned.
