WARNING
: Read and heed the warnings and cautions given
in Manual No. 30-1, General Safety Precautions for Powder
Systems and Equipment, before operating this equipment.
1.
Turn ON the system electrical power and air supply.
2.
Turn ON the booth exhaust fans.
3.
Fill the feed hopper 2/3 full with clean, dry powder. Start fluidizing
air and adjust to the pressure recommended
for your hopper
(typically 10-15 psi [0.7-1.0 bar]). Allow time for the powder to
become completely fluidized before spraying.
WARNING
: Breathing finishing powders may be hazardous to
your health. Obtain and read the Material Data Safety Sheets
for the powders you are using. Wear appropriate respiratory
protection when handling or spraying powder.
4.
Turn ON the electrostatic power supply main power switch. Do not
turn on the high voltage until air pressures are set.
5.
Adjust pump air pressures:
Atomizing: 30 psi (2.1 bar)
Flow Rate: 20 psi (1.4 bar)
NOTE:
Flow rate air pressure controls the volume and velocity of the
powder and air mixture delivered to the gun. Atomizing air pressure
controls the density (powder-to-air ratio) and velocity of the mixture.
The pressures given above are average starting points. Pressures will
vary due to required film build, line speed, and part configuration.
Adjust air pressures to obtain desired results.
6.
Test spray pattern and adjust air pressures and pattern sleeve, if
used, as necessary.
7.
Turn ON the high voltage at the electrostatic power supply. Adjust
to 100 kV.
