Assembly Stators as follows:

• Disassembly dispensing unit as follows:

- 5.1.1, Separating the dispensers

- 5.1.2, Taking the dispensers apart

• Assembley Stators, see 5.2, Assembly

Do not switch on the 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.

4.1 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.

• Connect the tank (supply line, cartridge) of the medium to
both dispenser medium inputs (B).
(See section 8, Technical specifications, page 21 for
details of the thread)

• Bring the eco-DUO 450 into vertical position.

• Position the static mixing pipe (24) and
lock in place.

For each dispenser:

• Connect the eco-DUO 450 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 450 from being wetted with the
medium.

• Unscrew the air bleed screw (27) with
washer (26) 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.
