Be sure that the personnel entering the spraying area has read and understood the safety
requirements stated in this manual and/or on the warning sign. Verify that any person entering the
spray area is correctly grounded with conductive sole shoes or personnal grounding straps.
Check that fans are in good operating condition.
Remove any useless parts from the spraying area and keep this area clean. Part holders and
conveyor hooks must be cleaned frequently. All conductive objects must be electrically grounded as
well.
PROCEDURE
To prime the pump and the connecting fluid line :
- Set the air pressure regulator (F) to 0 bar (0 Psi).
- Open the fluid drain valve (N).
- Immerse the suction and discharge hoses into the paint drum.
- Increase the air pressure by opening the air pressure regulator (F) so that the pump runs slowly.
- When the fluid begins to flow regularly from the discharge hose, close the fluid drain valve (N).
Remove the air cap, the nozzle and the air cap retaining ring from the Airmix ® guns.
Turn off the atomizing air.
Trigger the gun to dispense fluid into the fluid container.
If necessary turn on the knob assembly at the rear of the gun (J) counter clockwise, to open the gun
needle valve.
If necessary increase the fluid pump air pressure.
Release gun trigger when the fluid flows regularly from the gun nozzle.
If necessary install a clean tip into the air cap (KMX 3 Ex and KMC 3 Ex). Position the air cap
assembly over the needle seat or tip (KMP 3 Ex and KMC 3 Ex) and secure in position with the
retaining ring hand tightened onto the gun.
Adjust the atomizing air pressure on the air pressure regulator (D).
Caution : Be certain there is no air leak between the power supply air outlet (H) and the gun
air inlet (J).
Turn on the fan air control valve located on the gun (J).
Trigger the gun to dispense spray coating material out of the gun air cap.
Release the trigger.
Turn the ON / OFF power supply switch to "I" :
The green indicator LED (VOLTAGE) illuminates.
The green indicator LED (TEST) iluminates.
Set up the high voltage adjustment knob fully clockwise to 85 kV.
Turn the ON / OFF gun switch to "I".
Trigger the gun toward the grounded part to be coated.
When spraying :
The red and yellow indicator LEDS should illuminate.
The green indicator LED (TEST) should be off.
Adjust the following parameters :
Fluid flow rate :
On the air spray guns (KMP 3 Ex and KMV 3 Ex) adjust the fluid flow rate using the knob
assembly at the rear of the gun (turn it counterclockwise to increase the flow rate or
clockwise to decrease the flow rate).
Atomizing air :
Use the air pressure regulator (D) to adjust the atomizing air pressure.
Whenever possible, use the lowest air pressure to obtain efficient electrostatic wrap
around. Use the fan air control valve to adjust the spray pattern.
Electrostatic effect :
Set up the electrostatic wrap-around effect with the high voltage adjustment knob (from 20
to 85 kV).
