DANGER
Never ignore health hazards and always follow sanitary regulations.
Before using the MINISUMO II pump, some preliminary checks must be carried out:
Check the integrity of the pump.
Ensure that the pump is at operating temperature and that the piping is free of any air bubbles.
Ensure that the electrical connection has been carried out correctly.
With the pump started, ensure that the electric motor rotation direction matches the arrow on the motor’s
protective casing. If it turns in the opposite direction, reconnect as indicated on the electrical diagram attached to
the motor.
The unit can be opened and repaired only by specialized personnel.
