so may damage pump seals and/or other components and
will void the warranty.
Pumping should only occur in well ventilated areas.
Never fill containers in confined areas, e.g. inside a
vehicle. Do not operate pump in areas where vapours
can accumulate.
When using this pump in reverse care must be taken to
prevent contaminants entering pump.

grounded to earth. Ensure the floor or ground where
fuel is stored or dispensed is and remains electrical
conductive.
This pump is fitted with a 180-micron mesh strainer on
the suction tube side of the pump to prevent foreign
matter damaging the pump. If pumping in reverse, fit a
