ONCE A
- Check that the pipe connections are not loose to prevent any leaks;
- Check and keep the filter installed on the suction line clean.
WEEK:
ONCE A
- Check the pump body and keep it clean and free of any impurities;
- Check that the electrical supply cables are in good condition.
MONTH:
Long periods
Whenever it is thought that the system will remain unused for at least 15 days, it must be emptied
in order to prevent the product from crystallising inside. This shall be followed by a washing cycle.

PROBLEMS AND SOLUTIONS
For any problems contact the authorised dealer nearest to you.
PROBLEM
POSSIBLE CAUSE
Lack of electric power
THE MOTOR IS
Rotor jammed
NOT TURNING
Motor problems
THE MOTOR
Low voltage in the electric power line
TURNS SLOWLY
WHEN STARTING
Low level in the suction tank
Foot valve blocked
Filter clogged
Excessive suction pressure
High loss of head in the delivery circuit (working
with the by-pass open)
LOW OR NO
By-pass valve blocked
FLOW RATE
Air entering the pump or the suction piping
A narrowing in the suction piping
Low rotation speed
The suction piping is resting on the bottom of
the tank

CORRECTIVE ACTION
Check the electrical connections and the safety
systems.
Check for possible damage or obstruction of
the rotating components.
Contact the Service Department
Bring the voltage back within the anticipated
limits
Refill the tank
Clean and/or replace the valve
Clean the filter
Lower the pump with respect to the level of the
tank or increase the cross-section of the piping
Use shorter piping or of greater diameter
Dismantle the valve, clean and/or replace it
Check the seals of the connections
Use piping suitable for working under suction
pressure
Check the voltage at the pump. Adjust the volt-
age and/or use cables of greater cross-section
Raise the piping
Reduce suction pressure
Dispense until the air is purged from the by-pass
system
Verify the suction connections
Check and replace the seal
Remove the blockage from the suction circuit
Add liquid from pump delivery side
Remove the blockages from the suction and
delivery valves
