7.0 GROUNDING
INSTRUCTIONS
This vacuum cleaner must be properly grounded. If it should malfunction or
breakdown, grounding provides a path of least resistance for electric current to
prevent the build-up static electrical charge and to ensure that static electricity is
discharged to ground. The build-up of static electricity could create a sparking
hazard and an ignition hazard.
This vacuum cleaner is equipped with a static dissipating air supply hose with brass
fittings. It is the responsibility of the user to ensure that the compressed air supply
outlet is grounded. If the grounding of the air supply outlet is questionable, or if a
portable compressor is being used to power the pneumatic explosion proof vacuum,
a secondary grounding reel is available as an option for this pneumatic explosion
proof vacuum cleaner. The grounding reel may be used to connect the pneumatic
explosion proof vacuum cleaner to a secondary grounding source, such as a
grounding pole, in the event that grounded air supply outlet is not available or if the
pneumatic explosion proof vacuum is being powered by portable compressor.
WARNING:
This vacuum cleaner for use in potentially explosive
atmospheres is equipped with conductive wheels which allow
for the vacuum cleaner to be grounded with the floor. Do not
substitute the conductive wheels and use only replacement
conductive wheels supplied by the manufacturer.
WARNING:
To effectively dissipate static electricity and to ensure spark-
free operation, this vacuum cleaner must be grounded during
use.
DANGER:
Do not operate vacuum cleaner if the air supply outlet is not
properly grounded or if the grounding is questionable.
