INSTRUCTION MANUAL (Translated from the original in spanish)
of a speed regulation control that adjusts the work of
the pump to the system.
THE PUMP DOES NOT MUST NEVER RUN DRY.
3. INSTALLATION: COUPLING THE PUMP TO
THE MOTOR.
The pump is suitable for coupling to a 4" submersible
motor conforming to NEMA standards.
To obtain a correct coupling proceed as follows (Fig.
2): unscrew the fastening screws (B) and unhook the
outer pump box (G) to remove the cable protection
(A). Make sure the shaft, joint and mating surfaces
are clean.
Place the motor (C) in a vertical position.
Couple the pump to the motor taking care to align the
"cable grommet" opening in the lower bracket with the
motor cable outlet.
Once the coupling has been made, screw the nuts (D)
onto the tie rods (E) fixing the pump to the motor,
tightening them in sequence according to the diago-
nals or with a tightening torque of 16-20 Nm. Extend
the motor cable (F) along the pump (G) and cover it
with the cable protection (A). Hook the cable protec-
tion to the box and fix it with the screws (B).
The manufacturer declines any responsibility for
damage caused by wrong connections.

7. POSSIBLE FAULTS, CAUSES AND SOLUTIONS

If the engine does not start or water does not come out at the end of the pipe, try to discover the anomaly through
the list of the most common faults and their possible solutions
1) The motor does not start.
2) The motor works but does not give flow.
The flow rate does not correspond to the given curve.
3)
4) The engine stops and starts automatically.

4. MAINTENANCE
In times of frost, be careful to empty the pipes.
ATTENTION: in the event of a fault, the ma-
nipulation of the equipment can only be
carried out by an authorized technical service.

5. PRODUCT DISPOSAL

When the time comes to dispose of the pump, it does
not contain any toxic or polluting material. The main
components are duly identified in order to proceed to
selective scrapping.
This product or parts of it must be disposed of in an
environmentally sound way, please use your local
waste collection service.

6. TECHNICAL CHARACTERISTICS

Liquid temperature: ................................ 1ºC - 40ºC
Maximum amount of sand in suspension: ....... 100 g/m
Maximum immersion depth: .......................... 150 m
SOLUTIONS
Check fuses and other protection devices
Check that the pump is completely submerged
Check that the voltage corresponds to that marked on the
nameplate
Check geometric height plus head losses
Thermal reset or wait for cool down
Connect this pipe to the outlet of the pump
Put the gate valve to the outlet to reduce the flow rate of the
pump
Wait for well recovery
Reverse the direction of the valve
Contact an Official Technical Service
Check the electrical cable
