PURPOSE OF THE MACHINE
The machine is intended forcleaningof air-driven spray-guns that have been used for painting with water-based paint
systems.
The unit has two separate areas for cleaning:
1. An automatic washer (item 1 illustration 1), intended for cleaning of spray-guns with gravity fed paint-cups.
In this washer water or water-based solvents can be used.
2. A sink (item 2 illustration 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 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 air-driven extractor (item 3 illustration 1) over the flange of the automatic washer, and connectit to the
blue air-hose (taped on the backside of the unit)by sticking the hose into the connector of the extractor.
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.Take 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.

PLACING THE UNIT
DRESTER BOXER DOUBLE A 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).
Make sure that the unit is properly grounded by using the grounding cable (item6illustration 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 250 litres/
min (9cfm) of air.
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.
Tap-water connection
Connect a hose for tap water to the water inletconnector (item 13illustration 2).
The hose can be led into this connector via the slots on the side of the unit, or through the open back of the unit. In
either case, make sure that the hose do not bend the air-linesor in any other way harm the pneumatic system of the unit
Drain hose
Connect a drain hose to the drain outlet connector (item 12illustration 2). Lead it on to, and secure it well to a regular
drain-water system.
The hose can be led into this connector via the slots on the side of the unit, or through the open back of the unit. In
either case, make sure that the hose do not bend the air-linesor in any other way harm the pneumatic system of the unit
Ventilation
The air-driven extractor must be connected to a metal ducting to lead the exhaust outdoors. An alternative is to lead it
into a hood that is in turn connected to a suitable ventilation system approved for Zone 1. This hood should have an
open design so as to avoid constant extraction (see illustration10).
The metal ducting may not be longer than 15 metres, and must be connected in such a way as to ensure grounding.
PERMITTED SOLVENTS
The unit has two separate areas for cleaning:
14. Theautomatic washer (item 1 illustration 1). In this washer water or water-based solvents can be used.

15. The sink (item 2 illustration 1). In this sink water only shall be used.
Thinner/gun-wash must NOT under any circumstances be used in this machine.
PERMITTED SOLVENT DRUMS
The DRESTER BOXER DOUBLE Acan 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.
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
Solvent drum
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).
Place the drumto the left underneath the unit (item 2illustration 2). Insert the group of hoses containing the drainhose
from the automatic washer into this drum (item 4illustration 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.
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).
Water
Fill the filtrate container (item 7illustration 2) to 1/2 of the volume 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.
OPERATING INSTRUCTIONS
Empty the spray-gun of any residual paint into a separate spills-dish.
Open the main valve for compressed air (item 7 illustration 1).
Open the lid for the automatic washer (make sure it `clicks` into the full open position).
Place the spray-gun inside (see illustration 5).
Be sure to fit the trigger clip following illustration 6, and to push the spray-gun up against the nozzle for the paint-
channel (item 1 illustration 5) before you lock it into position with aid of the magnets of the trigger clip.
If you prior to cleaning prefer to remove the Air-cap and the needle of the spray-gun, then place those items as shown
by arrow 5 in illustration 5.
Close the lid, and start the automatic pre-wash cycle by pressing the foot pedal No.8 illustration 1. The spray-gun will
now be automatically cleaned for approx. 1.5 minutes with circulating solvent.
When the cleaning procedure is completed, the lid can be opened and the spray-gun taken out. It can now be manually
further washed or rinsed withwater.
By pressing foot pedal No.10 inillustration 1, recirculating water will be fed through the cleaning brush placed in the
sink (item 1 illustration 7). Note that the ball-valve on the brush (item 6illustration 7) must be in an open position.
The spray-gun’s paint channel can now be rinsed with clean water. Press the tapered nozzle of the rinse-gun (item 2
illustration 7) 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.
The brush and rinse-guninthe sink can be used independently of the automatic washer at any time.
Connect the spray-gun to the air-line on the left side of the machine (item 4 illustration1), and blow out the spray-gun
through the funnel in the sink (item 3 illustration 7). By using this funnel, you prevent the fumes from spreading within

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

OPERATION WITHOUT TAP-WATER CONNECTION
If tap water is not available at the site of the gun-cleaner, you have the option to use recycled water (obtained from the
filtering process) for the rinse-gun as well as thecleaning brush
In that case the machine should be reconnected as follows:
Disconnect the hose for the rinse-gun (item1illustration 9) from the valve-panel, remove the red plug from the cross-
junction on the pump (item2illustration 9) and fit the hose in it´s place.
The wash-brush as well as the rinse-gun in the sink will now both operate with recycled water by pressing foot-valve 10
illustration 2.
When using the rinse-gun, the valve on the wash-brush (item6 illustration 7) must be closed.
THE COAGULATION PROCESS
1. EMPTYING THE FILTRATE CONTAINER
When the water level reaches the level of the working platform (item 4 illustration 7), it is time to perform the coagulation
process. The filtrate container (item7 illustration 2) must however first be completely drained of its remaining content.
Remove the front panel (item 5 illustration 1) by lifting it up-and-out.
Turn the lever(item 9 illustration 2) to open position, turn the leaver on the cleaning-brushin the sink to a closed position
and start the draining by opening the valve for the pump (item 8illustration 2). The pump will now completely drain the
filtrate container through the drain hose and 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 as well as for the drain hose.
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 7).
B: Open the valve for the water agitator (item 5 illustration 7).
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 theagitator 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

CHANGINGTHEFILTER
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.
