Prevent disconnected not pressurized compressed air supply lines from restarting. If the systems
leaks, disconnect it from air supply and then tighten the screwed connections.
3.5 Excitation for operating instructions
Operating instructions are regulations that a company creates for safe operation. These are binding
instructions issued by the entrepreneur within the framework of his management right. The
employees are obligated to follow these instructions.
The general obligation of the entrepreneur to create and publish operating instructions is laid down
in the Occupational Safety and Health Ordinance (BetrSichV), the water resources law (WHG) and,
where applicable, the Ordinance on Hazardous Substances (GefStoffV). The present operating
instructions are therefore to be complemented by national regulations on accident prevention (UVV)
and environmental protection.
Give information to the employee about:
• the dangers involving the handling of contaminated parts and the solvents used, the necessary
protective measures and behavior, including instructions in case of danger and first aid.
• Type and scope of periodic inspection for safe working condition of the device
• Environmental Protection
• Safe handling of the pneumatic system
• By means of instructions and controls, the user has to ensure cleanliness and clarity at the
workplace of the device.
• The responsibility for operation must be clearly regulated by the user and must be complied by all
persons, so that no unclear competences occur under the safety aspect.

Acids are not permitted. Paint strippers or other additives (e.g. brake cleaners etc.)
may must not be used in the washing unit.
Safety data sheets relevant to the products supplied should always be available on the
premises. These will contain the information about the cleaning agents that you are
using.
Never alternate the use of solvents and cleaning fluids (for water-based paints) in the
same machine as this will damage it and void the warranty. Follow the manufacturer’s
instructions at all times. Alternating the two types of cleaning agents can cause gas
build up and explosions!
When changing from solvents to cleaning fluids for water-based paints (or vice-versa)
the paint gun washer must be completely cleaned of paint, water and fluid residues.
Recommendation to reduce solvent consumption:
If the unit shall be connected to a continuously running exhaust when using solvent,
we recommend the pneumatic exhaust damper to reduce solvent consumption.
See B-TEC, catalog no.: 10000348 / ATEX version.
4. Approved Cleaning Agents

Horizontal and industrial floor
Conductive industrial floor (max. conductive resistance 10
8
Ohm).
Follow the safety instructions according to the zone designations (chapter 6.).
6. Requirements for the Installation Site
This device is classified as machine category 2, group II, machine type explosion group II B and can be
used in zone 1.
See also device type sign: II 2 G c II B T6
Safety regulations for the installation site of B-TEC devices
The risk zoning around the cleaning machine and the possible creation of an explosion protection
document is, in accordance with legal requirements, the operator´s obligation, because this division
is inter alia depending on the solvents used and various conditions such as the ventilation. However,
at this point the operator should be supported with general advice to comply with the obligation.
Helpful advice can also be read at DGUV rule 113‐001, DGUV rule 109‐010 and also DIN EN 12921‐1
and ‐3.
For example, in many cases the classification of the zones looks like this:
Zone 1 => The interior of the machine
Zone 2 => In periphery of 1,0 – 1,5 m
Identify the different zones with appropriate warning and prohibition signs. Marks at the floor can be
helpful. In the area surrounding the unit, open flames and other ignition sources (e.g. welding or
grinding equipment places) are not allowed. Similarly, smoking is prohibited. Temporary work with
ignition must be approved in writing and appropriate additional safety precautions must be adhered
to (remove all combustible materials, classification of a fire station,...).
Foundation, building
Dry and protected from frost.
Very well ventilated and means of ducting the exhaust fumes to an approved area.
Follow the safety instructions about the site.
Maintain the ambient temperatures (5° - 35°C / 41°F - 95°F) and do not expose the machine
to direct sunlight, as this carries a risk of overheating.
Space requirement for operation and maintenance
The device can be placed or be mounted on a wall. In front of the device, there should be space of
1,5m.
Cleaning Device d-800 Page 16
equipment and facility engineering
Waste air hose
Attention! Only use original B-TEC
waste air hoses. Risk of fire if
other hoses are used.
7. Transport and Installation
The machine is delivered in carton.
Take the machine out of the carton and bring it to the installation site.
7.1 Connecting Exhaust
The waste air hose must lead outside. Place the waste
air hose minimum one meter lengthwise for optimal
work of the exhaust system. Stretch the hose as far as
possible in order to avoid a reduced flow crosssection. This is necessary in order to ensure that the
exhaust system works well. One has to ensure that
the fumes are not led into areas where people are
likely to be. The waste air has to be exhausted safely.
This means that it has not to be fed into chimneys
serving furnaces or fireplaces and not into exhaust
channels of spraying and drying cabinets.
You can adjust the exhaust air flow at the throttles as needed for the length of the waste air hose.
Cleaning Device d-800 Page 17
equipment and facility engineering
A pressure-regulating valve has to be used if the
compressed air connections do not have the required
operating pressures. Use only dry and oil-free air!!
The machine has a grounding connection and may not be operated without being
grounded. In the proximity of the pumps there is a grounding cable, which has to be
grounded safely by a qualified person (e.g. electricians). Customer-provided solvent
tanks have to be grounded separately!
Compressedair connection
7.2 Connecting Compressed Air
One compressed air connection has to be provided by the plant, depending on the machine:
Operating pressure max. : 600 kPa (6 bar ; 87 psi)
Operating pressure min. : 500 kPa (5 bar ; 73 psi)
7.3 Grounding
After proper installation and connection to the compressed air supply, the cleaning unit can be
commissioned.
The brush may only be used as intended.
It shall never face towards the operator.
Unnecessary dry-run oft the pumps should be avoided!
Do not open the device cover while it is running in automatic
mode! If necessary move the timer to “0”.

To use this cleaning device, you have to read the operating manual first! A
commissioning without attention of the operation manual can cause damage
to persons, objects and the environment. Please wear personal protective
Fire and ignition sources are not allowed in an area of 5m around the device (such as
grinding machines or welding plates). Smoking is also forbidden!
Please mark areas which are vulnerable to flames with appropriate signs.
Compressed air supply has to be guaranteed.
The following solvent/was fluid drums are required:
If using the RK water-soluble paint fluid it MUST be diluted in the ratio of 2 volumes of fresh tap
water to one volume of RK e.g. pour 10 litres of RK into the 30 litre container and fill to 30 litres with
20 litres of water:
equipment 3.3 Safety Precautions
One 60 litre drum, approx. half filled with fluid* and one 30 litre drum filled with fresh solvent or
diluted fluid.
*The 60 litre drum is for recycling but must be ‘charged’ with fresh fluid in order to start re-cycling.
If mounted at the wall, you might have to use smaller drums suitable for the height of the cleaner.
8.1 Commissioning
1. Remove the front cover of the machine and position the drums as shown on page 5.
2. Insert the black discharge hose ( 23) and grey intake hose into the 60 l drum, which is
provided for contaminant dilution and circulating material. Insert the transparent intake
hoses into the 30 l drum provided for fresh thinner and material.
3. Replace the front cover of the machine.
Now, the cleaning device is ready to work.
8.2 Operational Procedure
Working with the manual side of the machine (cf. pages 4f)
Open the door. The exhaust starts automatically. Activate the pump of the brush with the toggle
switch labeled „Brush“. Circulating solvent flows out of the brush. The output can be adjusted with a
pressure reducing regulator that is located in front of the pump. Activate the pump of the spray jet
with the toggle switch labeled „fresh Jet“. Fresh solvent flows out of the spray jet (30 liters drum).
You can adjust the output at the throttles as needed with the black throttle valve behind the
operating panel.
When the manual cleaning area is not longer in use, switch it off and close the door. The exhaust
stops automatically.

equipment and facility engineering
Do not open the door while automatic washing cycle is running. If necessary, turn
the timer to "0".
With the jet gun, positioned at the front of the machine, you can dry objects or spray guns. If you
unclamp the compressed-air quick connect, you can substitute the jet gun by the cleaned spray gun
and exhaust it in the exhaust opening.
Working with the automatic side of the machine (cf. pages 4f)
Open the hinged door. The exhaust system starts automatically. Then install the gun as described
below:
1. Remove the lid of spray gun and place it in the lid holder. Make certain that the paint-soiled
inner surface faces downwards → towards the interior of the washer.
2. Place the spray gun, with the cup, on the center nozzle upside down with the paint channel.
If a strainer is used in the spray gun, then the cup needs to be unscrewed. Place the cup
upside down on the cup holder (receptacle next to the center nozzle.) Remove the screen
filter from the spray gun, and place on one of the tines of the cover holder. Next, place the
spray gun upside down on the center nozzle.
3. The spray gun trigger is pulled back with the trigger clamp located in the washing chamber.
This ensures that solvent flows through the paint channel of the spray gun. In addition, it is
necessary to ensure that the set screw is in "opened"-position so that the air flow is possible.
4. Connect black compressed air hose to the connection on the spray gun.
This ensures that air is forced into the air channels of the spray gun during the cleaning
process and that solvent and paint residues are prevented from entering.
5. Close the hinged door from the gun-cleaner. Do not allow the doors or hatches on
the machine to fall shut. All machine doors and hatches must be operated with
appropriate care and caution by the user.
6. Set timer for 2-3 minutes. The main cleaning cycle is activated. Solvent is drawn from the 60
liters drum and circulates. The timer can be reset to zero by hand. When the set time is over,
open the hinged door slowly and check the cleaning result.

equipment and facility engineering
7. Since the solvent is circulated when the timer is used, it will be heavily contaminated after a
certain period. If a paint film remains on the spray gun after the main cleaning cycle, the gun
has to be cleaned manually using the fresh solvent jet.
8. For automatic rinsing, close the door again and press and hold the rinse button (red button)
for 3-4 seconds. Thinner is drawn from the 30 l drum on the left side. The spray gun is rinsed
on the inside and outside with fresh thinner.
9. Open the door to the automatic cleaning chamber and dry the spray gun with the cup and
cover in their mounting brackets. Use the jet gun for this procedure.
10. The spray gun is clean. Reassemble and bring it back into production.
Clean the spray gun as soon as possible after the painting process.
Before insert the spray gun, unscrew the cover from the cup and empty out the remaining
paint into a collecting container. For example the B-TEC residue collecting station RST-01.
The more thoroughly the cup is emptied, the longer the solvent or cleaner can be used.
Following these steps will ensure optimal cleaning results and long machine life.
8.3 Adjusting Facilities

9. Care and Maintenance
9.1 Maintenance of the Machine
We recommend cleaning the stainless steel filter on the intake hose at regular intervals (at
least at every solvent/fluid change.) → if the filter is defective, it must be replaced
immediately. Defective filters either have heavy paint buildup, causing clogging of the filter
surface, or, the filter has a breach that allows contaminated solvent to be drawn in by the
pump, which can damage the pump or clog the washing nozzle.
Clean the perforated stainless steel grates and the interior walls of the machine at regular
intervals. Remove any residues from the drain pans under the grids to ensure rapid solvent
run-off.
It is recommended to use each function of the device shortly at least once a day in order to
avoid drying of the membranes inside the pumps and keeping the jets clean.
When the machines are not to be operated for a longer period of time (for example during
vacations) a clear rinse should be used after the final cleaning cycle so that the jets will not
be clogged with heavily contaminated solvent. In the unlikely event that the cleaning jets
do become blocked, then they can be easily unscrewed from the machine and cleaned
separately in neat solvent or cleaning solution and then re-fitted to the machine.
Replacement jets are available as spare parts.
The operating permission will expire, if other than original B-TEC spare parts are used.
