Spray Area
Fire Hazard
Improper or inadequate opera-
tion and maintenance proce-
dures will cause a fire hazard.
Protection against inadvertent
arcing that is capable of causing
fire or explosion is lost if any
safety interlocks are disabled
during operation. Frequent Pow-
er Supply or Controller shut-
down indicates a problem in the
system requiring correction.
Fire extinguishing equipment must be present in
the spray area and tested periodically.
Spray areas must be kept clean to prevent the ac-
cumulation of combustible residues.
Smoking must never be allowed in the spray area.
The high voltage supplied to the atomizer must be
turned off prior to cleaning, flushing or mainte-
nance.
When using solvents for cleaning:
•
Those used for equipment flushing should
have flash points equal to or higher than those
of the coating material.
•
Those solvents used for general cleaning must
have a flash point at minimum of 5°C (9°F)
greater than the ambient temperature. It is the
end users responsibility to insure this condition
is met.
•
Spray booth ventilation must be kept at the
rates required by NFPA-33, OSHA, country,
and local codes. In addition, ventilation must
be maintained during cleaning operations
using flammable or combustible solvents.
Electrostatic arcing must be prevented. Safe
sparking distance must be maintained between the
parts being coated and the applicator. A distance
of 1 inch for every 10KV of output voltage is re-
quired at all times.
Test only in areas free of combustible material.
Testing may require high voltage to be on, but only
as instructed.
Non-factory replacement parts or unauthorized
equipment modifications may cause fire or injury.
If used, the key switch bypass is intended for use
only during setup operations. Production should
never be done with safety interlocks disabled.
Never use equipment intended for use in water-
borne installations to spray solvent based materi-
als.
The paint process and equipment should be set up
and operated in accordance with NFPA-33, NEC,
OSHA, local, country, and European Health and
Safety Norms.
