Air Heater Assembly - Safety
AREA
Tells where hazards
may occur.
Spray Area
LN-9245-00.8
HAZARD
Tells what the hazard is.
Fire Hazard
Improper or inadequate
operation and maintenance
procedures will cause a fire
hazard.
Protection against inadver-
tent arcing that is capable of
causing fire or explosion is
lost if any safety interlocks
are disabled during opera-
tion. Frequent Power Supply
or Controller shutdown indi-
cates a problem in the system
requiring correction.
SAFEGUARDS
Tells how to avoid the hazard.
Fire extinguishing equipment must be present in
the spray area and tested periodically.
Spray areas must be kept clean to prevent the
accumulation 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 main-
tenance.
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 used for general cleaning must have
flash points above 100°F (37.8°C).
Spray booth ventilation must be kept at the rates
required by NFPA-33, OSHA, country, and local
codes. In addition, ventilation must be main-
tained during cleaning operations using flam-
mable or combustible solvents.
Electrostatic arcing must be prevented. Safe
sparking distance must be maintained between
the parts being coated and the applicator. A dis-
tance of 1 inch for every 10KV of output voltage
is required 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 unauthor-
ized 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 dis-
abled.
Never use equipment intended for use in water-
borne installations to spray solvent based ma-
terials.
