8.5.3 SPRAYING WITHOUT GUN FLUSH BOX
Provide grounded metal bucket to collect the products to be disposed of.
Insert spray nozzle into manual gun.
The product pressure of the components is set depending on the required product
ow rate. Thereby, keep in mind that the the B-component pressure must be higher
(5 to 10%) than that of the A-component.
Select the requested paint recipe on the screen (home page). In case of two spray
guns, select the requested gun(s).
Start the coating process by means of the START push button.
Filling
For electrostatic spray guns: switch o electrostatics.
Point the manual gun with inserted spray nozzle into the grounded metal bucket.
Open the trigger mechanism of the spray gun step by step. Avoid splashback.
The 2K product starts to ow and the B-component is dosed proportionally to the
A-component. During lling, three screens in turn inform you of lling progress:
B_04637
From product valves to mixer.
B_04638
From mixer to splitter valve.
B_04639
From splitter valve to gun.
As soon as the complete high-pressure hose is lled with 2K product, the following
will happen:
"Filling" screen switches to the home page.
The green START push button begins to light up.
Remote control (Option): The green lamp begins to light up.
Atomizing air is added (option).
Correctly mixed product is not transported from the gun until after lling.
Coating
For electrostatic spray guns: safety precautions according to corresponding the
operating manual.
Start coating of an object.
The ushing agent pressure for A and B must always be applied at the device.
The ow rate of the system depends on:
the product pressure,
the hose lengths and cross-sections,
the nozzle and
the viscosity of the products.
Without AIS, the B pulse valve should operate every 0.5 to 3 seconds, according to the
ow rate. The switching frequency can be optimized by adjusting the pressure of the
hardener pump or through the stroke length of the hardener dosing valve. The higher
the pulse rate is, the more homogeneous is the mixing of the two components.
