Overload protection
NOCCHI DPC series pumps have a built-in thermal protection switch. The pump stops if an overload condition occurs.
The motor restarts automatically after it has cooled down (see chap 7 of the Troubleshooting section for information
on causes and corrective actions).
Chap. 6 Start-up (see fig. 1 pag. 91)
Use the pump for the applications listed on the nameplate.
Instructions for a safe pump start
The power cable should have a minimum section equivalent to that of H05 RN-F. To be able to use the pump outdoors,
it is necessary to use cable with a length of 10 m. The plug and connections should be protected by water splashes.
The maximum suction level of 3 mm can be reached in manual mode only. If the level of the fluid to suck is below 20
mm, maximum suction, up to a residual level of 3 meters, can be attained more quickly by starting and topping the
pump 2 or 3 times.
Automatic mode
NOCCHI DPC pumps have an integrated floating switch. When the water reaches the start-up level, the integrated
floating switch automatically starts the pump.
When the water falls below the stop level, the integrated floating switch stops the pump.
1. Lower the front lever and place it in location "AUT" (see Fig. 1).
2. Place the pump in a stable and straight position so that the integrated floating switch is able to move freely.
3. To start the pump, insert the plug in a 230 V current socket.
Manual mode:
The integrated floating switch is disabled so that the pump can run in continuous mode:
1. Lift the front lever and place it in position "MAN" (see Fig. 1).
2. To start the pump, insert the plug in a 230 V current socket.
Chap. 7 Maintenance and troubleshooting (see fig. 2 pag. 91)
Make sure the machine is disconnected from electric power supply, before performing
maintenance operation.
In ordinary conditions, NOCCHI DPC series electropumps do not require any maintenance.
It may be necessary to clean the hydraulics or replace the impeller.
Cleaning the hydraulic components

Clean the impeller (Fig. 2 ref. C) and its chamber (Fig. 2 ref. D)
Reassemble the suction filter (Fig. 2 ref. A) by tightening the screws (Fig. 2 ref. B) and making sure that the O-ring
(Fig. 2 ref. E) is correctly positioned in its housing (Fig. 1 ref. E).
Cleaning the floating switch.
Disassemble the suction filter (Fig. 2 ref. A) by removing the screws provided (Fig. 2 ref. B).
Remove the rubber stop (Fig. 2 ref. F) supporting the guide rod (Fig. 2 ref. G)
Remove the floating switch.
Clean the floating switch (Fig. 2 ref. H) and the related chamber (Fig. 2 ref. I).
Insert the floating switch in the guide rod (G) making sure it is inserted in the correct direction (tapered side pointing
upwards).
Insert the rubber stop (Fig. 2 ref. F) on the side of the guide rod.
Reassemble the suction filter (Fig. 2 ref. A) by tightening the screws (Fig. 2 ref. B) and making sure that the O-ring
