Operation manual
PURPOSE OF THE MACHINE
The unit is intended for cleaning of air-driven spray-guns using either thinner-based solvents or water-based solvents.
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
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 (see detail illustration 2)
– Fit the glass window into place (item 4 illustration 1) (see detail
illustration 3)
– The air-line on the left side of the unit (item 5 illustration
- is during transport placed inside the unit. Take it out, and fasten it with
the magnet in a convenient 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 6 illustration 1) is during transport placed inside the unit. Take it out, and fasten it with the magnet in a convenient place on the right side. This air-gun is intended to blow the spray-gun dry after the cleaning procedure.
PLACING THE UNIT
The DRESTER DIX11 is equipment Category 2 (ref. ATEX directive 2014/34/EU) and
may therefore be placed in locations classified as Zone 1 (ref. ATEX-directive
1999/92 EC).
If the DRESTER DIX11 is installed in locations classified as Zone 2 or in
unclassified locations, the following is valid provided that the ventilation
of the unit is installed as described further down in this manual: The space
within 1 m of the DRESTER DIX11 is to be classified as Zone
2, and the inside of the ducting as Zone 1 (see illustration 16).
Within these areas, 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, please contact the local fire service authorities for advice.
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 (illustration
4). To access this point, remove the front panel (item 7 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 5
illustration 1). This air-line is intended to blow out the sprain after the
cleaning procedure.
Grounding the unit
Make sure that the unit is properly grounded by using the grounding cable
(illustration 5).
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 complies with local laws and regulations.
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
- directly to a metal ducting, which is in turn connected to a ventilation system approved for Zone 1.
Option 2: Fit an air–driven AIRVENT 11660 to the hood and connect this in turn to a metal ducting. Connect this ducting to a ventilation system approved for Zone 1.
Option 3: Connect the hood to an ATEX approved electric ventilator via a metal ducting. The exhaust from the ventilator must be led outdoors.
PERMITTED SOLVENTS
The unit can be used with solvents and solvent mixtures intended for spray-gun
cleaning, such as acetone, toluene, is butanol, xylene that are listed as
Group IIA according to IEC 79-20 (EN 60079-20).
The unit can also be used with water or water based solvents.
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.
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.
PERMITTED SOLVENT DRUMS
The DRESTER DIX11 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
solvent in 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 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 drums that is
large enough to hold the volume of at least one leaking drum.
PREPARATIONS FOR USE
Solvent drums
Remove the front panel (item 7 illustration 1) by lifting it up-and-out.
Drum plugs
There are several types of solvent drums on the market, each with different
diameter of the opening. With the unit, cardboard boxes with a selection of
tapered plugs are supplied (see illustration 3). Select the plugs that fit
well into the opening of the drums, and fit them onto the drum adaptors of the
hoses (see illustration 4).
Solvent fill-up
Follow the following procedure for the left side of the unit:
Use one empty drum and another drum of the same size full of clean solvent.
Place the empty drum to the left underneath the unit (item 1 illustration 8).
Insert the group of hoses containing the drain hose from the sink into this
drum (item 2 illustration 8). 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 1 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 8). Insert the 6mm hose into this drum
(item 4 illustration 8). Make sure that the hose is 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.
If only recirculating solvent will be used in the machine, put all the hoses
for each washing compartment into the same drum (Illustration 9).
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 8 illustration 1).
Open the lid, and place the spray-gun inside (illustration 10, 11 and 12). Be
sure to fit the trigger clip (Illustration 13) and connect the air line (item
1 illustration 10). Gravity-fed sprayguns also require an extension pipe (item
2 illustration 10).
For the gravity-fed spray-gun, you always get the best cleaning result if the
spray-gun is dismantled and placed in the washing compartment as seen in
illustration 10.
The air line (item 1 illustration 10) prevents solvent from entering the
spray-gun’s air channels during washing.
This air line should be equipped with a conical plug that fits into the spray
gun’s air inlet (illustration 14).
Close the lid, and start the automatic pre-wash cycle by turning the Timer
knob (item 9 illustration 1).
The spray-gun will now be automatically cleaned for 1 to approx. 4 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 rinsed with clean solvent if required.
As long as the valve (item 10 illustration 1) is turned on, a jet of clean
solvent will be sprayed from the nozzle under the lid.
Finally, it is possible to blow out the spray-gun. Connect the spray-gun to
the air line on the left side of the machine (item 5 illustration 1), and blow
out the spray-gun through the funnel under the lid. By using this funnel, you
prevent the fumes from
spreading within the premises.
Close the lid after cleaning.
Finally, all of the spray-gun’s channels can be blown out with the air-gun on
the right side of the unit (item 6 illustration 1), which can also be used to
dry the spray-gun.
SAFETY VALVE
The unit is equipped with a safety valve that will interrupt the automatic pre-wash cycle if the lid is opened before the cycle is completed. To resume the interrupted cycle, the lid and the unit’s main valve (item 8 illustration
- must be closed. When you hear the safety valve ‘click’, the main valve can
be opened again.
To speed this process up, open the valve to activate the spray nozzle (item 10 illustration 1) and close it when you hear the safety valve ‘click’.
SERVICE
Weekly:
– Loosen the centre bolt holding the spray-cradle and remove it.
– Clean the washing compartment´s working platform (perforated pressing) and
the bottom of the washing compartment.
– Reassemble the parts.
Monthly:
– Remove the five nozzles automatic washer and clean them with clean solvent.
(illustration 15).
When changing drums:
– Check and if necessary clean the strainer on the suction hose for
circulating solvent.
