USE AND MAINTENANCE INSTRUCTION MANUAL
For three phase pumps it is imperative that electrical connections are made so that
the impellers rotate in the correct direction. If the pumps are run in the wrong
direction for more than a few seconds serious damage may result which will
invalidate the guarantee.
Read paragraphs 10.3 before installation for the method of checking correct
direction of rotation.
Although the filters are self-cleaning there may over time be a build-up of detritus
in the pores of the mesh which the self-cleaning mechanism cannot remove.
For stainless steel filter mesh use a pressure washer to very thoroughly clean the
outside of the mesh.
For nylon screens either clean low pressure water or replacement inserts are
available from Rotorflush Filters Ltd.
If the pump is run with the filter screen clogged it may cause the pump to overheat
and seriously damage the motor invalidating the guarantee. The use of appropriate
cos phi load monitoring and dry running protection is essential with all models.
In most conditions the filter should be inspected every 2 months. In some
situations it may require more frequent inspection and if required cleaning.

screens should be cleaned with gentle running water or replaced. It is
recommended that nylon screens are replaced at these intervals:
