property damage, or unnecessary damage to the pump.
This manual must be read and understood both by the
installing personnel and the responsible trained
personnel/operators prior to installation and operation,
and it must always be kept close to the location of the
pumping unit for easy access.
B. SUMMARY OF SAFETY MARKING. The safety
instructions contained in this manual follow specific
ATEX safety marking where non-observance of the
instruction will cause a hazard is specially marked with
the symbol:
