2.1 Spray head combinations
We recommend selecting the air cap (B)
with the corresponding precision dosing
needle (A) depending on the medium
viscosity.
The appropriate combination must be
selected and tested separately for each
application (viscosity, dosing quantity/
time and temperature).
2.2 Retrofitting the spray head
• Undo the union ring (2)
• Remove the air cap (29). The seal (30) remains either in the spray head or stuck to the
air cap (29)
• Carefully attach the nozzle mounting tool (31) to the precision dosing needle (28),
unscrew the precision dosing needle and replace it with another one
• Attach an air cap (29) and re-tighten the union ring (2)

5Initial commissioning
5.1 Inserting the stator
• Switch off the dosing control
• Unplug the power supply from the drive unit
• Undo the union ring (2)
• Remove the air cap (29). The seal (30) remains either in the spray head or stuck to the
air cap (29)
• Carefully attach the nozzle mounting tool (31) to the precision dosing needle (28) and
unscrew the precision dosing needle
• Unscrew the screws (8) and remove the air housing
Dispenser Do not switch on until medium has been delivered. Otherwise there is a risk
of damage to the equipment.Even a brief period of dry running can lead to the
stator being destroyed.

• Unscrew the screws (18) and remove the end piece (27)
• Loosen the grub screws (14) by approximately three rotations and remove the drive
unit (11) from the pump housing (10)
• Attach the star-shaped coupling (5) to the assembly aid (6)
• Dock the assembly aid (6) with the star-shaped coupling (5) on the dispenser
housing (10)
• Turn the stator (7) on the rotor (4) – which is wet with medium – until the dowel pin (8)
begins to dip into the keyway (9)
• Lightly press the stator in the direction of the dispenser housing (10) and turn the
assembly aid (6) in the direction of the arrow until the stator has been guided into the
dispenser housing

• Uncouple the assembly aid and re-attach the star-shaped coupling (5) to the drive
unit (11).
• Insert the drive unit (11) into the dispenser housing (10). Ensure that the anti-rotation
lock (A) is positioned within the designated recess in the dispenser housing (10)
• Tighten both grub screws (14) and secure the end piece (27) with the screws (18).
Ensure that the anti-rotation lock (B) is positioned within the designated recess in the
end piece (27)
• Attach the air housing and precision dosing needle. Follow the steps in the reverse
order to the process shown in Fig. 5
5.2 Making the electrical connection
Connect the eco-CONTROL EC200 dosing control and eco-CONTROL SC1200 control
unit according to their respective operating and maintenance instructions.

5.3 Supplying and bleeding the medium
• Connect the tank (supply line, cartridge) of the
medium to the dispenser medium (A)
• Connect the transparent hose (2) (with an inner
diameter of 4 mm) to the bleed valve (23)
• Pressurise the medium
• Slowly open the bleed valve (23) by
approximately half a turn until the medium
escapes without bubbles
• Close the bleed valve and remove the hose
Tip Ensure the hose in use is sufficiently long (approx. 20 cm) and capable of holding the
entire medium required for the bleeding process. You can then dispose of this
conveniently at the end of the process.
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.

6Operation
Operation takes place according to the operating and maintenance instructions using the
eco-CONTROL EC200 dosing control and eco-CONTROL SC1200 control unit.
7Cleaning
• Switch off and disconnect the power supply from the drive unit and remove the medium
supply
• Dismantle the dispenser as outlined in section 5.1, Fig. 5 and Fig. 6
• Unscrew the valve attachment (32) for the bleed valve (23)
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.

• Dock the assembly aid (6) with the star-shaped coupling (5) on the dispenser
housing (10)
• Turn the assembly aid (6) in the direction of the arrow. The stator (7) will be pushed so
far out of the dispenser housing (10) by the rotor assembly (4) that the dowel pin (8) is
no longer in the groove (9)
• Uncouple the assembly aid (6) from the dispenser housing (10) and completely remove
the stator (7) from the rotor assembly (4) by turning and pulling
• Unscrew four screws (26) and pull off the pump housing (19) from the bearing
housing (13)
