THE COAGULATION PROCESS

1. CHECKING THE FILTRATE CONTAINER

When the water level reaches the level of the working platform (item 4 illustration 7B), it is time to perform the

coagulation process.

First check that the remaining content of the filtrate container (item 7 illustration 2) is not higher than 25mm (1").

2. 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 FILTERS WILL

IMMEDIATELY BECOME OBSTRUCTED, AND CANNOT BE RE-USED.

A: Remove the working platform (item 4 illustration 7B).

B: Open the valve for the water agitator (item 5 illustration 7B).

C: Add the coagulation powder as recommended by the paint manufacturer.

D: Stir the powder with a stick for a moment to avoid that it sinks down to the bottom in lumps.

D: Allow the agitator to run for a few minutes.

E: Stop the agitator 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 agitator.

3. FILTRATION

Open the drain-valve (item 10 illustration 2) and drain the wash-basin completely into the filter (item 11 illustration 2). Clean the

inside of the wash-basin thoroughly with the cleaning brush (i.e. with recycled water), so that any remains of residual flocks are

completely drained into the filter.

When this is done, close the drain-valve

CHANGING THE FILTER

N.B.: MAKE SURE THAT YOU USE ORIGINAL DRESTER FILTERS, NR. 8701 (MAIN FILTER), AND NR. 8702 (PRIMARY

FILTER). THESE FILTERS HAVE BEEN TESTED AND APPROVED BY THE PAINT MANUFACTURERS.

The primary filter (item 2 illustration 11) collects most of the coagulated sludge, while the main filter (item 1 illustration 11) collects

the finer paint particles.

Remove the sludge from the primary filter after each coagulation process (once it is completely dry, the sludge is easy to remove

from the filter). By doing so the primary filter can be re-used up to 10 times.

The main filter will gradually become blocked after trapping the finer paint particles. In general, the main filter can be used for up

to 5 coagulation processes. The main filter must however be changed every 1-2 months, otherwise there is a risk that mould will

develop.

N.B.: THE COAGULATION SLUDGE MUST BE HANDLED IN ACCORDANCE WITH REGULATIONS FROM THE

APPROPIATE AUTHORITY. INFORMATION FROM THE PAINT SUPPLIER MAY BE NECESSARY.
