This manual

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

eco-CONTROL EC200. The operating and maintenance manual must have been read

and understood in full before commissioning or carrying out maintenance work on the

eco-PEN450.

The dispenser

The dispenser is supplied with these components and accessories:

Safety

All instructions in the Safety section of the maintenance and operating manual for the

dosing system must be complied with and implemented.

Starting up for the first time

4.1

Inserting the stator

Preparation

: Unplug the power supply to the drive unit.

1. Undo the union ring (2).
2. Pull off the end piece (3).
3. Couple the assembly aid (6) to the dispenser housing (10)

(the star-shaped coupling (5) must be attached to the dispenser housing).

4. Wet the rotor (4) with the medium or a suitable lubricant.
5. Turn the stator (7) (on the bearing side, see Fig. A) on the rotor (4) until the dowel pin

begins to dip into the keyway (9).

6. Lightly press the stator in the direction of the dispenser housing (10) and turn the

assembly aid in the direction of the arrow until the stator has been guided into the
dispenser housing.

7. Uncouple the assembly aid, install the end piece and the union ring, and put in place

the required Luer-Lock needle.

Dispenser

Do not switch on

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.

4.1.1 Connecting the dosing unit to the drive unit

1. Turn the set screws (14) in the thread such that they do not protrude into the coupling

area.

Danger of damage to the fit

2. Attach the star-shaped coupling (5) onto the coupling of the drive unit( 11).
3. Couple the drive unit (11) to the dosing unit (20) until there is a gap <1 mm between

the anti-rotation lock (8) and the dosing unit (20).

4. Set the anti-rotation lock (8) correctly in place by rotating the dosing unit (20).
5. Bring the drive unit (11) and the dosing (20) together completely.
6. Lightly turn the set screws (14), the drive unit (11) has now been centred properly.

4.1.2 Supply and bleed the medium.

• Connect the tank (supply line, cartridge) of the medium to the dispenser medium input

(12). (See section

10, Technical specifications,

, page

for details of the thread)

The Dispenser can be bled in one of two ways after the medium has been supplied.

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.

Version 1.8

Version B

(e.g. open cartridge, Dispenser fixed in place and supply of the medium under pressure)
• Turn the bleed screw (23) 180 degrees so that the bleed hole is in the position shown

(direction of the drive unit).

• wait until the medium emerges from the bleed hole free from air bubbles.
• Release (remove) the primary pressure on the medium and wait until no more medium

comes out of the bleed opening.

• Remove the ejected medium and close the bleed screw (23) again.
Connect the Dispenser to the power supply and convey the medium until there are no

more air bubbles in it and the outlet nozzle (with the Luer-Lock needle) comes out.

Alternatively, the air can also be extracted from the pump area with the syringe (9)

included in the scope of supply.

Version A

(e.g. supply via a hose, closed cartridge)
• Dispenser bring it into a position in which the end piece

(3) points upwards.

• Dispenser connect the unit to the power supply and

convey the medium until there are no more air bubbles
in it and the outlet nozzle (with the Luer-Lock needle)
comes out.

Tip

: Connecting a hose can protect the Dispenser from

being wetted with the medium.

Cleaning

Preparation

Remove the dosing needle,

danger of injury!

Disconnect the power supply of the drive unit and uncouple it from the dosing unit (in the

reverse order to that described in

4.1.1, Connecting the dosing unit to the drive unit,

page

1. Undo the screws (18) and pull out the front dispenser housing (19) with the O-ring (22)

from the module (15) while turning it slightly.

2. Undo the union ring (2).
3. Pull off the end piece (3).
4. Pull the stator (7) out of the front dispenser housing (19).
5. Undo the bleed screw (23) and the washer (24).
6. Clean all the parts.

Assembly:

1. Attach the dispenser housing (19) with the O-ring (22) to the module (15) with the

screws (18) (do not exceed a tightening torque of 0.35 Nm).

2. Install the stator in accordance with work steps 4. to 7. described in section

4.1,

Inserting the stator,

page

3. Connect the dosing unit to the drive unit (see

4.1.1

, page

Note

: Do

not

rinse out the rotor

housing (15), because that could
damage the bearings! Clean it
with a cloth and brush.
