STARTING THE UNIT (SEE FIG. 1)
WARNING
Use the electric pump for the type of uses listed on the plate.
WARNING
Do not let electric pump run dry, the hydraulic parts and seal could be damaged and if it is used with diesel fuel, the heat
which develops could create a fire risk.
WARNING
Do not run the electric pump with the delivery or the interception valve closed, if it is used with diesel fuel, the heat which
develops could create a fire risk.
Before starting the electropump fill the suction pipe and the electropump body by using the filling cap, making sure that there are no
leaks, close the cap and start the electropump. Check that it rotates clockwise when looking at the electropump from the side of the
motor fan. For the three phase electric pumps it is possible to invert the rotation by changing the order of two phases, in order to do
this disconnect the pump from electric power supply.
If the electric pump does not work for long periods of time repeat the filling operations before starting it up.
CHAPTER 6

MAINTENANCE AND TROUBLE SHOOTING

DANGER - ELECTRIC SHOCK RISK
Before doing any operation, make sure machine is disconnected from electric power supply.
Under normal conditions PGA, DELTA OIL and DIESEL LINE electropumps do not need any type of maintenance.
In order to avoid possible failures, it is advisable to periodically check the pressure supplied and current absorption.
A decrease in pressure is a symptom of wear.
An increase in the current absorption is a sign of abnormal mechanical friction in the electric pump.
If the electropump is not going to be used for long periods of time (e.g. an entire season) it should be emptied completely, rinsed with
clean water and put in a dry place.
PROBLEM
THE ELECTROPUMP DOES
NOT PUMP WATER THE MOTOR DOES NOT RUN
THE MOTOR RUNS BUT THE ELECTROPUMP
DOES NOT PUMP LIQUID
THE ELECTROPUMP STOPS AFTER RUNNING
FOR A SHORT PERIOD OF TIME BECAUSE
ONE OF THE THERMAL MOTOR PROTECTION
DEVICES TRIPS
DIESEL FUEL LEAKAGE FROM THE DRAIN PIPE
If the problem has not been eliminated after carrying out the above operations contact the closest service centre.

POSSIBLE CAUSE
1) No power.
2) Motor protection tripped.
3) Defective condenser.
4) Shaft or impeller blocked.
1) It is taking on air.
2) Suction height is excessive.
3) Filter or valve obstructed.
4) Wrong rotation direction.
1) Power supply does not conform to data on plate.
2) A solid object is blocking the impeller.
3) The liquid is too thick.
1) Seal worn or broken.
REMEDY
Check if there is power and if the plug is plugged in
properly.
Wait until the motor cools down.
Replace the condenser.
Verify the cause and unblock the electropump.
Make sure that the joints are airtight.
Check that the level of liquid has not dropped below
the foot valve.
Check that the foot valve is airtight and is not blocked.
Reset the rotation direction.
Check the voltage on the power supply conductor
cables.
Dismantle the electropump and clean it.
3) Change electropump type.
