INSTRUCTIONS FOR USE
For best cleaning result, spray guns should be cleaned immediately after use.
1.CLEANING
Before the machine is used for the fi rst time, the fi ltrate container (see item 6 in Picture 1) must be fi lled to 3/4 of the volume with
clean water. This water will be re-used (recycled water).
* Disconnect the spray gun from compressed air and empty any remaining paint into a paint waste container. To activate the
pump, press the foot pedal (see item 9 in Picture 1). As long as the foot pedal is pressed down, recycled water (fi ltrated water) will
be pumped through the cleaning brush when the ball valve is open (see item 12 in Picture 1). Pull the trigger on the rinse gun (see
item 13 in Picture 1) and press the footpedal (see item 9 in Picture 1) to get recycled water through the rinse gun.
* Clean the cup and the cap using the brush (see item 12 in Picture 1). Use the rinse gun to rinse it (see item 13 in Picture 1).
* Clean the paint channel of the spray gun by placing the paint inlet against the tapered nozzle of the rinse gun(see item 13 in
Picture 1).
* Clean the outside of the spray gun using the brush (see item 12 in Picture 1). Use the rinse gun to rinse it (see item 13 in Picture
1).
* Dry the spray gun , cup and cap using the blow gun (see item 11 in Picture 1).
* In addition to the steps above, you can connect your spray gun to the blow-out air line (see item 14 in Picture 1) and pull the
trigger to blow out any remaining fl uid.
2. FLOCCULATION AND FILTRATION
When the mix of paint and water reaches the level of the working platform (see item 10 in Picture 1), it is time to perform the
fl occulation and fi ltration.
It is important that the fl occulation is thoroughly carried out. If not the fi lters (see item 1 and 2 in Picture 3) will become
obstructed and cannot be re-used.
* Make sure the fi ltrate container (see item 6 in Picture 1) is clean and has maximum one inch of fl uid left.
* Remove the working platform (see item 10 in Picture 1).
* Turn the lever (see item 4 in Picture 1) to start the agitation.
* While stirring with a measuring stick or similar, add fl occulation powder, as recomended by the paint manufacturer, usually
approximately fi ve scoops for full batch using Drester 9211 fl occulation powder.
* When all fl occulation powder is thouroughly mixed in, let the agitation run for three minutes. Let it rest for one minute then turn
the agitator on for one more minute.
* Remove any sludge, left from previous fi ltration, from the pre-fi lter (see item 2 in Picture 3) and open the drain valve (see item 8
in Picture 1) to drain the dirty water through the fi lters.
* Clean the inside of the sink using the cleaning brush and close the drain valve (see item 8 in Picture 1). Re-fi t the working
platform (see item 10 in Picture 1).
NOTE: Clean the sink imidiately after draining, to prevent paint residue build up.
CHANGING THE FILTER
The pre-fi lter (see item 2 in Picture 3) collects most of the coagulated sludge, while the main fi lter (see item 1 in Picture 3) collects
the fi ner paint particles.
Remove the sludge from the pre-fi lter after each coagulation process (once it is completely dry, the sludge is easy to remove from
the fi lter). By doing so the pre-fi lter can be re-used up to 10 times.
The main fi lter will gradually become blocked after trapping the fi ner paint particles. In general, the main fi lter can be used for up
to 5 fl occulation processes. The main fi lter must however be changed every 1-2 months, otherwise there is a risk that mould will
develop.
N.B.: THE FLOCCULATION SLUDGE MUST BE HANDLED IN ACCORDANCE WITH REGULATIONS FROM THE
APPROPRIATE AUTHORITY. INFORMATION FROM THE PAINT SUPPLIER MAY BE NECESSARY.
