1This manual
Dear customer,
This manual forms part of the operating and maintenance manual for the dosing system

• eco-DUO 600
• 2 Stators
• 2 drive units (without Fig.)
• Assembly aid
• 2 screwdrivers
• 2 Allen wrenches
• Calibration adapter
• Attachment plates (2 x)
• Mixer set (3 static mixers)
• Commissioning and maintenance manual
3Safety
All instructions in the Safety section of the
maintenance and operating manual for the
dosing system must be complied with and implemented.

4Starting up for the first time
Assembly Stators as follows:
• Disassembly dispensing unit as follows:
- 5.1.1, Separating the dispensers
- 5.1.2, Dismantling the dispenser
• Assembley Stators, see 5.2, Assembly
4.1 Connecting the dosing units to the drive units
• Turn the set screws (21) in the thread such that they do not protrude into the coupling
area. Danger of damage to the fit.
• Attach the star-shaped couplings (22) onto the coupling of the drive units (A).
• Couple the drive units (A) to the dosing units until a gap of <1mm is achieved between
the anti-rotation lock (23) and the dosing units.
• Position the anti-rotation lock correctly by turning the dosing units.
• Bring the drive units and dosing units together completely.
Do not switch on 2K dispenser until medium has been delivered to it. Otherwise there is
a risk of damage to the equipment. Even a brief period of dry running can lead to the
stator being destroyed.

4.2 Connecting sensors for monitoring dosing pressure
Attention:
The sensor cables must not be drilled during assembly!
Connect both sensors to the flowscreen analysis system*
* According to the instructions provided.

4.3 Supplying and bleeding the medium.
• Connect the tank (supply line, cartridge) of the media to
both dispenser medium inputs (B).
(See section 8, Technical specifications, page 21 for
details of the thread)
• Bring the eco-DUO 600 into vertical position.
• Position the static mixing pipe (24) and lock in place.
For each dispenser:
• Connect the eco-DUO 600 to the power supply and
convey the medium until it comes out of the static mixing
pipe free from bubbles*.
Tip: Connecting a hose to the mixing pipe can protect the
eco-DUO 600 from being wetted with the medium.
• Unscrew the air bleed screw (27) with washer (28) to
bleed. Wipe off leaking medium with a cloth.
Tip: Never use the same cloth for both mediums. It would
cause a reaction between the components.
• Tighten the air bleed screw again.
* When filling for the first time, the blocking medium is first
removed from inside the dispenser (stator).
Follow the safety stipulations and instructions of the manufacturer of the medium
to be used to fill the unit. If applicable, use the required protective equipment. If
the medium is being conveyed for the first time, there is a danger from medium
spurting out. Air bubbles can cause uncontrollable spurting out. Ensure that you stand
back a safe distance.

4.4 Calibration
A calibration adapter is available for calibrating the eco-DUO 600. It is mounted on the
outlets. The eco-Control EC 200-DUO calibration programmes can be used to determine
the exact dosing quantities and save them for the calculation in the dosing programmes.
Calibrating the dispenser
• Remove the static mixing pipe.
• Unscrew the screws (9) in the locking plate (11).
• Mount the calibration adapter (35)
• Carry out the calibration in accordance with the eco-
Control EC 200-DUO operating manual.
Once calibration is complete, fasten the locking plate and
position the static mixing pipe.

4.5 Recommendations for problem-free operation
Notice: These experience values apply for a wide variety of dual-component media.
Always follow the manufacturer recommendations for your product in addition to these.
• Mix ratio for very short dosing times
Dual-component media display mostly varying properties (viscosity). They therefore
emerge from the outlets with different pressures. This means that deviations in the
mixing ratio can usually be noted at the start of dosing. Selecting a suitable mixing pipe
is essential to the result.
• Retraction with dual-component media
Retraction ensures a clean break of the thread. If it is set too large, the already mixed
product enters the dispenser, causing them to react with each other.
• Note the pot life
Before breaks in work, rinsing (filling completely) the mixing pipe with one of the two
components prevents the two components from reacting inside the mixing pipe.
As it is not possible to prevent the two components from coming into contact on the
outlets, this measure is not suitable for every break in production.

4.6 Cleaning the outlets
This type of dosing station requires some dismantling when cleaning with high viscose
products. During this activity attention must be paid to the chemical properties and
chemical reactions of the products. Please contact the manufacturer of your mix product
if necessary.
Tip: In certain cases, rinsing the dosing station may be easier than dismantling and
cleaning the components.
• Set the dosing station to manual mode and secure against unauthorised operation.
• Loosen the static mixing pipe from the dosing mixing head and dispose of in accordance
with the manufacturer instructions.
• Clean the connection thread/bayonet catch and holes. Ensure that the two components
are not mixed.
• Hold the mixing head with the outlet pointing downwards and clean the holes (outlets)
individually.
Outlets
They are accessible when the static mixing pipe is removed.
• Catch any product leakage and clean the mixing head
again. Ensure that the two components are not mixed. Use
separate cloths.
• Protect the connection threads and outlets of the product
against drying out and soiling where necessary (e.g. with a
cap and/or by applying lubricant * on the relevant areas.
Follow the product manufacturer instructions).
* Recommendation: OKS-469, OKS www.oks-germany.com

5.1.2 Dismantling the dispenser
On both dispensers:
1. Unscrew the screws (6) and remove the end piece (5B).
2. Couple the assembly aid (25) to the dispenser housing (2) (the star-shaped
coupling (22) must be attached to the dispenser housing). Turn the assembly aid in
the direction of the arrow until the stator (4) can be removed from the dispenser
housing.

3. Remove the stator*.
4. Unscrew the screws (3) and pull the dispenser housing (2) with round section seal (26)
off the rotor strand seal housing (1).
* If the stator cannot be removed easily, proceed from 6 and remove the stator when the
rotor strand seal housing has been removed.
5. Undo the air bleed screw (27) and the washer (28).
6. Clean all the parts.
Do not immerse the end piece (5B, Fig. 9) in liquid, rather simply wipe it clean.
Only clean the dosing channel with dull and soft objects.
Do not rinse out the rotor strand seal housing (1), as that could damage the
bearings! Clean it with a cloth and brush.

5.2 Assembly
For assembly, the work steps outlined in
the previous section are carried out in
reverse order.
Important:
• Wet the rotor (26) with the medium or a
suitable lubricant.
• Turn the stator (4) into the correct
position on the rotor (26) to ensure that
the dowel pin (7) can be immersed in
the relevant groove in the dispenser
housing (2).
• When combining the end piece (5B) and
the pump housing (2) ensure that they
are parallel so that the dispensers can
be assembled suitably to each other at
a later stage.
Tip: Carry out the assembly on an even
surface.
