CHAPTER 5
ELECTRIC PUMP INSTALLATION (SEE FIG. 1)
DANGER - ELECTRIC SHOCK RISK
When installing, please ensure pump is disconnected from electrical supply.
DANGER - ELECTRIC SHOCK RISK
Never use the electric cable to support the electric pump.
DANGER - ELECTRIC SHOCK RISK
Be careful not to damage the electric cable when lowering it into the well.
DANGER - RISK OF BURSTING
This type of pump can develop high pressure. If a collection tank or expansion tank 15 is to be installed, it is
advisable to install a pressure limiter valve 16 between the tank and the pump.
DANGER - RISK OF BURSTING
All of the pipes and installation parts must have a maximum working pressure which is greater or equal to
the maximum pressure of the pump, if this is not possible it is necessary to use a pressure reducer.
WARNING
Protect the electric pump and all pipes from freezing.
• Join the pump body and the motor,
verifying that the electric cable is
correctly positioned next to grooves
on the hydraulic unit supports
• Tighten the nuts on the 4 motor tie
rods, alternatively on the diagonals
• Position the electric cable along the
pump and reassemble the protection
raceway by tightening the screws to
the hydraulic unit
• Fix the sand protection filter to the
lower support of the hydraulic unit
body by using the screws provided for
this purpose
