SAFETY
RansFlex Applicators - CONTENTS

Fire Hazard
Improper or inadequate
operation and maintenance
procedures will cause a re
hazard.
Protection against inadvertent
arcing that is capable of causing
re or explosion is lost if any
safety interlocks are disabled
during operation. Frequent
Power Supply or Controller
shutdown 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
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, ushing or maintenance.
When using solvents for cleaning:
•Those used for equipment ushing should have ash
points equal to or higher than those of the coating
material.
•The ash point of the cleaning solvent shall be at
least 15° C (27° F) above the ambient temperature.
Otherwise, the cleaning process must be carried
out in an area with forced air ventilation. 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 ammable 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 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 unauthorized
equipment modications may cause re 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 waterborne
installations to spray solvent based materials.
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.
