Ch. 4 ELECTRICAL CONNECTIONS
The installer must make sure that the electric system is
grounded in accordance with the law in force.
WARNING
Verify that the voltage and frequency of the electropump
shown on the nameplate correspond to those available
on the mains.
DANGER
Electric
shock risk
DANGER
Make sure that the electric system has a high-sensitivity
circuit breaker
Δ =30 mA (DIN VDE 0100T739).
Electric
shock risk
Electropumps have a plug with double ground contact at the end of the power supply cable. In this case the elec-
tropump is grounded by inserting the plug in the socket.
Overload protection
SUB is a single-phase electropump with in-built thermal circuit breaker and automatic reset and doesn’t therefore
require any external protections.
Ch. 5 STARTING THE UNIT
WARNING
WARNING
Do not operate the electropump without liquids, to avoid
damaging hydraulic parts and seal.
Use the electro-pump in the performance fi eld listed
on the information label
WARNING
Do not oparate the electropump when the interception
valve on the delivery side is completely closed.
Connect the pipe to the 1” 1/4 delivery mouth before starting the electropump.
Connections must be made so as to avoid losses.
Start the pump by inserting the plug in an appropriate outlet.
In ordinary working conditions electropumps of the SUB series do not need any maintenance.
It may be occasionally necessary to clean the fi lter or other hydraulic parts.
If the electropump is not going to be used for long periods of time (e.g. an entire season) it should be completely
emptied, rinsed with clean water and stored in a dry place.
Cleaning the fi lter
- If the sucked water is not perfectly clean, it may be necessary to clean the fi lter with a steel brush to scrape the
dirt accumulated on the external surface.
It is also possible to clean the internal section of the fi lter.
Loosen the screw that fi xes the fi lter to the body of the electropump and remove it.
Scrape the dirt with a steel brush and rinse it with clean water.
If this is not suffi cient, have the hydraulic parts cleaned by an authorised centre.
