Ch. 3 INSTALLATION
DANGER
Electric
shock risk
Avoid using the electric cable to lift or transport the pump.
Use a stainless steel or nylon rope, suitable to sustain the weight, to immerse the electropump.
Two slots are present for allowing the anchoring of the head of the electro-pump.
Anchor the rope so that it balances the weight of the electropump.
It is advisable to connect the electric cable to the delivery with plastic straps, at a distance of about 3 m, when using
rigid piping.
It is also advisable to fit automatic level controls to prevent the electropump from running without liquids and a
pressure gauge (suitable to the electropump model) to verify its performance during operation.
Ch. 4 ELECTRICAL CONNECTIONS
WARNING

Electric
shock risk
DANGER
Electric
shock risk
Electropumps have a plug with double ground contact at the end of the power supply cable. In this case the
electropump 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.

All the operations that concern the installation must be
carried out with the pump disconnected from the energy
supply.
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

Ch. 5 STARTING THE UNIT
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.
Ch. 6 - MAINTENANCE AND TROUBLESHOOTING
In ordinary working conditions electropumps of the SUB series do not need any maintenance.
It may be occasionally necessary to clean the filter 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 filter
- If the sucked water is not perfectly clean, it may be necessary to clean the filter with a steel brush to scrape the
dirt accumulated on the external surface.
It is also possible to clean the internal section of the filter.
Loosen the screw that fixes the filter 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 sufficient, have the hydraulic parts cleaned by an authorised centre.
