WARNING
WARNING
Do not operate the electropump without liquids, to avoid
damaging hydraulic parts and seal.
Use the electro-pump in the performance field 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 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.
