PURPOSE OF THE MACHINE
The machine is intended forcleaningof air-driven spray-guns that have been used for painting.
The left side of theunit has two separate areas for cleaning:
1. An automatic washer (items 1Aillustration 1), intended for cleaning of spray-guns with gravity fed paint-cups.
In this washereither thinner-based solvents or water-based solventscan be used.
2. A sink (items 2Aillustration 1), intended for manual cleaning of other tools used in connection with vehicle
paint-jobs like: spray-guns with suction fed paint-cups, filler scrapers, paint brushes and such.
In this sinkeither thinner-based solvents or water-based solventscan be used.
The rightsideof the unit has one area for cleaning:
a. A sink (item 2Billustration 1), intended for manual cleaning of air-driven spray-guns that have been
used for painting with water-based paints, as well asof other tools used in connection with vehicle water-basedpaint-
jobslike: filler scrapers, paint brushes and such.
In this sink water only shall be used.
All other use of the unit are not allowed like:
Emptying excess paint into the unit
Cleaning of electric chargeable items
Collecting of various waste
Cleaning of textile materials
Storing of items
Cleaning of hands or other parts of the human body
Cleaning of any items for food or drinks
The coagulation processdescribed below (according to recommendations from the paint manufacturer) allows the
cleaning water to be re-used. CHECK CAREFULLY WITH THE APPROPRIATE AUTHORITY TO ENSURE THAT THE
FILTERED WATER OBTAINED AFTER THE COAGULATION PROCESS MAY BE EMPTIED INTO THE REGULAR
DRAIN-WATER SYSTEM. YOU MAY NEED INFORMATION FROM THE PAINT MANUFACTURER WHEN DOING SO
ASSEMBLY
First of all, check if the machine has been damaged during the transport. Remove the packaging and
check again that the machine has not been damaged during the transport. If so, report this immediately to the transport
company.

Fit the flange for the extraction (item 3 illustration 1) with the 4 screws included
Fit the glass window into place (item 13 illustration 1)
The air-line on the left side of the unit (item 4 illustration 1)is during transport placed inside the unit.Take
it out, and fasten it with the magnet in a suitable place on the left side. This air-line is intended to blow out the spray-gun
after the cleaning procedure.
The air-gun on the right side of the unit (item 12 illustration 1)is during transport placed inside the unit.T
ake it out, and fasten it with the magnet in a suitable place on the right side. This air-gun is intended to blow the spray-
gun dry after the cleaning procedure.

PLACINGTHEUNIT
The DRESTER BOXER TRIPLE C is equipment Category 2 (ref. ATEX-directive 94/9 EC) and may therefore be placed
in locations classified as Zone 1 (ref. ATEX-directive 1999/92 EC). If the DRESTER BOXERTRIPLE C is installed in
locations classified as Zone 2 (or in unclassified locations), the area within a radius of 1 m from the DRESTER BOXER T
RIPLEC is to be classified as Zone 1, and within a radius of an additional 2.5 m from the unit as Zone 2 (total
classification: 3.5 m around the machinery and 1 m above it). Within this area, all equipment such as electrical items
must be approved for the Zones described. Equipment that generates naked flames or sparks (e.g. welding or grinding
equipment) may not be used in this area. Smoking is not permitted. If in any doubt, contact the local fire service
authorities for advice.
Make sure that the unit is properly grounded by using the grounding cable (item6 illustration 2).
This manual is part of the unit and must be available at all times.
INSTALLATION
Compressed air
The unit must be connected to compressed air of 7-12 bar (110-180 psi). When in use, the unit consumes 150 litres/
min (6 cfm) of air (450 litres/min (16 cfm) if connected to a DRESTER AIRVENT 11660).
The air is to be connected to the moisture trap inside the unit (item 1 illustration 2). To access this point, remove the
front panel (item 5 illustration 1) by lifting it up-and-out.
The air-line can be led into this point via the slots on the side of the unit, or through the open back of the unit. In either
case, make sure that the air-line do not bend the hoses or in any other way harm the pneumatic system of the unit.
To prevent pressure drops, the air line and couplings must be adequately dimensioned. The regulator on the unit is pre-
set to 6.5 bar (100 psi). This is the optimal setting and must not be altered.
The compressed air supplied to the unit must be clean and dry. If it is not first led through a water trap and filter, it may
cause damage to the pneumatic components of the unit, which will invalidate any warranty claims.
Fit a connector to the air-line on the left side of the unit (item 4 illustration 1). This air-line is intended to blow out the
spray-gun after the cleaning procedure.
Ventilation
There are three different options for the unit’s ventilation. For all three options, it must be ensured that the speed of the
air flow at the opening of the hood is at least 0.5 m/s (this corresponds to a ventilation volume of 500 m3/h (310 cfm)).
The ventilation must be connected in such a way as to ensure the grounding of all parts.
Option 1: Connect the flange of the hood (item 3 illustration 1) directly to a metal ducting, which is in turn connected to
a ventilation system approved for Zone 1. The ventilation capacity must be at least500 m3/h (310 cfm).
Option 2:Fit an air-driven DRESTER AIRVENT 11660to the hood and connect this in turn to a metal ducting. This
ducting can either lead outdoors or be connected to a ventilation system approved for Zone 1. The ducting must have a
smooth inner surface, may not be longer than 15 metres and shall be installed so that it is as straight as possible.
Option 3: Connect the hood to an electric ventilator of a kind like DRESTER MINIVENT 2055 via a metal ducting. The
exhaust from the ventilator must be led outdoors.

PERMITTED SOLVENTS
The left side of the unit:
This side can be used with solvents and solvent mixtures intended for spray-gun cleaning, such as acetone, toluene,
isobutanol, xylene that are listed as Group IIA according to IEC 79-20 (EN 60079-20).
Never use any solvent if it is not provided with an MSDS (Material Safety Data Sheet). Read the MSDS carefully, and
follow all the instructions and procedures provided in the MSDS. If unsure, or if more information is needed concerning
the solvent, please contact your solvent supplier.
Do not add other chemicals to the solvent including, but not limited to, kerosene, gasoline, detergents, fuel oil or
chlorinated solvents.
The rightsideof the unit:
In the Sink on this side (item 2Billustration 1) water only shall be used.
General:
All solvents must have a pH value between 4 and 10. Be sure not to mix water-based solvents with thinner-based
solvents. It is important that all users are informed of what solvent is being used, at all times.
PERMITTED SOLVENT DRUMS
The DRESTER BOXER TRIPLE C can be used with different types of drums, but they must comply with the following:
The drums must fit into the unit
The drums must be leak-free.
The drums must be made of a conductive material.
Check for local regulations concerning max allowed volume for keeping solvents at the site of the unit
Solvent drums are not provided by Hedson Technologies, thus Hedson Technologies does not take any responsibility
for the drums. Follow the solvent supplier’s instructions carefully.
COLLECTING TRAY
The unit must be installed in such a way as to prevent accidental leakage of solvent or contaminated water from
spreading into a drain water system, thus representing a hazard to the environment. This can be done by:
installing the unit in a location where floor and walls can hold any accidental drum leakage, or
equipping the unit with a collecting tray beneath the solvent drum and water containerthat is large enough to
hold the volume of at least one leaking item.

PREPARATIONS FOR USE
Remove the front panel (item 5 illustration 1) by lifting it up-and-out.
Remove the foot-pedal console (items 6 illustration 1) by lifting it up and folding it out to the side (see illustration 2).
Solvent drums for the left side of the unit:
Two drums are needed, one drum that is empty, and one drumfull of solvent.Both drums must be of the same size, and
they must meet the requirements described under chapterPERMITTED SOLVENT DRUMS. Both drums must be
clean on the inside and they must not contain any solids or other objects that could be sucked into the pumps when
running.
Drum plugs
There are several types of solvent drums on the market, each with different diameter of the opening. With the unit, a card
board box with a selection of tapered plugs is supplied (see illustration 3). Select the plugthat fit well into the opening of
the drums, and fit them onto the drum adaptor of the hoses (see illustration 4).
Solvent fill-up on the left side of the unit:
Use one empty drum and another drum of the same size full of clean solvent.
Place the empty drumto the left underneath the unit (item 2 illustration 2). Insertthe group of hoses containing the drain
hose from the sink into this drum (item 4 illustration 2). Make sure that the hoses are properly led well down into the
drum, and that the opening is well sealed by the tapered plug.
Take the second drum, the one full of solvent, and pour half of its contents directly into the gun cleaner’s sink (item 2
illustration 1). The solvent that is poured in will drain into the drum underneath the gun cleaner. Make sure to have the
ventilation running during this procedure.
Place the second drum, now half full, on the floor on the right-hand side of the first drum (item 3 illustration 2). Insertthe
second group of hoses containing a white hose into this drum (item 5 illustration 2). Make sure that the hoses are
properly led into the drum all the way down to the bottom, and that the opening is well sealed by the tapered plug.
The solvent system is now filled-up. Both drums should be half full. The left-hand drum, contains the solvent that will be
recirculating for the automatic wash cycle, and the right-hand drum contains clean solvent for rinsing.The contents of
the right drum will gradually be used up and transferred to the left drum.
Water
Fill the filtrate container (item 7 illustration 2) up to 100mm (4”) under the upper edge with clean water.
Operating instructions
Operating instructions should be formulated on the basis of this manual and translated into the language spoken by the
employees. It should always be available close to the machine. To avoid confusion, the employees must be informed
about the solvent currently being used in the machine.

Finally, the spray-gun can be blown dry by using the air-gun on the right side of the unit (item 12 illustration 1).

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 theagitator.
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.
