The pumps of this series are not suitable for table fountains or aquariums. In these cases, it is necessary to use a H07
RN-F cable. If these pumps are used in continuous mode for ponds with fish, it is necessary to check them at regular
intervals of 6 months (if the water contains aggressive substances). It is also advisable to check the maximum
dimension of particles recommended for the pump and take the necessary measures to prevent the fish from being
sucked into the pump.
Chap. 4 Installation (see Fig. 1-3)
When installing, please ensure pump is disconnected from electrical power supply.
To prevent possible injuries to people, avoid inserting hands into the mouth of the pump
if this is connected to the electrical power supply.
NOCCHI DPC pumps come with a check valve that prevents the delivery pipe from being drained and the fluid from
recirculating.
If the pump is fixed in a permanent location with rigid pipes, it is advisable to install a quick closing fitting in the most
convenient location to facilitate cleaning and maintenance.
The dimensions of the collection chamber should allow the insertion of the pump and reduce to the minimum the start-
up operations per hour (see LIMITATIONS - Technical data).
Use the handle provided to transport or lift the pump.
To use the pump for temporary applications, install a flexible pipe and connect it to the pump using a pipe holder. To
immerse the pump, use a rope and fix it to the handle.
The pumps used in ponds, small lakes, fountains or similar installations or close to them should have a safety switch.
Contact a specialised electrician.

1. Remove the part that is not being used from the standard fitting cutting it with a knife.
2. Tighten the standard fitting on the pump.
3. Connect the pipe to the standard fitting.
Chap. 5 Electric Connection
Verify that the voltage and frequency of the electropump shown on the nameplate
correspond to those available on the mains.
The installer must make sure that the electric system is grounded in accordance with the
law in force.
Make sure that the electric system has a high-sensitivity circuit breaker
VDE 0100T739).
The power cable must be replaced by qualified personnel only.
Grounding
The plug of the power cable has a double grounding contact, so that grounding can be performed by simply inserting
the plug.

The fitting supplied with NOCCHI DPC pumps can be adapted to the dimensions of the pipe
used.
To connect a threaded pipe or a 3/4" (19 mm) quick closing fitting, tighten it directly on the
threaded part (location a).
When using a Ø 25 mm (1") pipe, cut the stage that is not being used at the correct height
(up to point b).
When using a Ø 32 mm (1 1/4"), cut the stages that are not being used at the correct height
(up to point c).
