INSTRUCTIONS FOR USE
It is important to make sure that the lever (see item 5 in Picture 3) 'clicks' into exactly the right position when choosing a
function.
For optimal cleaning result, spray-guns should be cleaned immediately after use.
1.CLEANING
Before the machine is used for the first time, the filtrate container (see item 5 in Picture 1) must be filled to 3/4 of the
volume with clean water. This water will be re-used (recycled water).
Empty the spray-gun of any residual paint into a separate spills dish. Turn the lever (see item 5 in Picture 3) to "Washing"
position (see item 1 in Picture 3). As long as the foot pedal (see item 7 in Picture 1) is depressed, recycled water will be
pumped through the cleaning brush. Use the cleaning brush to clean the spray-gun.
Then rinse the spray-gun's paint channel with clean water. Press the tapered nozzle of the rinse-gun (see item 11 in Picture
1) against the paint channel of the spray-gun. Pull the triggers on the spray- and rinse-guns simultaneously. Then rinse the
outside of the spray-gun with the rinse-gun.
2. EMPTYING THE FILTRATE CONTAINER
When the water level reaches the level of the working platform (see item 10 in Picture 1), it is time to perform the
coagulation process. The filtrate container (see item 5 in Picture 1) must however first be completely drained of its
remaining content.
Turn the lever (see item 5 in Picture 3) to "Draining" position (see item 3 in Picture 3) and start the draining by opening the
valve for the pump (see item.4 in Picture 3). The pump will now completely drain the filtrate container through the drain
hose into the regular drain-water system.
You will be able to tell when the filtrate container is empty, since the pump will start to run faster. Then close the valve for
the pump.
N.B.: When the pump runs faster it sucks air only. This will not harm the pump.
3. COAGULATION
N.B.: IT IS ABSOLUTELY VITAL THAT THE COAGULATION PROCESS IS CARRIED OUT WITH THE GREATEST
CARE, SO THAT LARGE FLOCKS OF COAGULATED PAINT ARE FORMED. OTHERWISE THE FILTER WILL
IMMEDIATELY BECOME OBSTRUCTED, AND CANNOT BE RE-USED.
A: Remove the working platform (item 10 in Picture 1).
B: Turn the lever (see item 5 in Picture 3) to "Stirring" position (see item 2 in Picture 3). Open the valve for the pump (see
item 4 in Picture 3). Since the pump now will pump air only, the water will start to bubble and get stirred.
C: Add the coagulation powder as recommended by the paint manufacturer. Stir it thoroughly into the water with the help
of a suitable instrument, such as a whisk or similar.
D: Allow the pump to run for a few minutes. Stir the water again to dissolve any residual powder that may have sunk to the
bottom.
E: Stop the pump occasionally for around 30 seconds since this improves the coagulation process. The total coagulation
time is around 5-10 min, depending on the amount of powder, the level of contamination, etc.
When this is done, close the valve for the pump.
