S
Never use an open flame to clean the unit or components of the unit.
S
Do not store flammable materials in the spray area or room. Keep
paint pumps, pressure pots, and containers of flammable coating
materials or solvents far enough away from spray booths to prevent
their inclusion in a booth fire. If a fire or explosion occurs, flammable
materials in the area will increase the chances and the extent of
personal injuries and property damage.
S
Make sure that the room where you are working is sufficiently
ventilated. Avoid breathing vapors over prolonged periods of time.
S
Check interlock systems periodically to ensure their effectiveness.
WARNING: Operating faulty or electrostatic equipment is
hazardous and can cause electrocution, fire, or explosion.
Make resistance checks part of your periodic maintenance
program.
S
Check all ground connections periodically with a megohm meter.
Resistance to ground must not exceed one megohm. If sparks or
arcing occur, shut down the system immediately.
S
Connect all disconnected equipment ground cables and wires after
servicing the equipment. Ground all conductive equipment.
WARNING: Service lines connected to panel disconnect
switches will still be energized unless power is shut off at
another disconnect ahead of the panel. Make sure the power is
off before servicing. Wait 5 minutes for capacitors to discharge
after shutting off the electrical power.
S
Turn off the electrostatic power supply and ground the gun electrode
before adjusting or cleaning the nozzles, fluid tips, or air caps.
S
If a “power on” test is required, perform the test carefully and then
shut off and lock out power as soon as the test is over.
S
Never troubleshoot the power supply without first disconnecting all
external power supplies and discharging the high-voltage capacitors
with an insulated screwdriver.
S
Ground electrodes and electrostatic cable ends before touching them.
