4 Installation
● If not done, put dispenser in a vertical
position. Mixer tip points downward.
● Open vent screw with sealing ring
11/12
on the pump.
Start with channel A and then with
channel B.
☞
Note!
Don´t loose the sealing ring
12 .
Caution!
At first the initial filling of a sealing product from the interior of the dispenser is purged.
● Activate the controller dispensing program by pressing Start/Stop and start a
dispensing cycle.
● Stop dispensing.

4.9 Recommendations for problem-free operation
☞
Note!
These experiences apply for a wide variety of dual-component adhesives. Always follow
the manufacturer recommendations for the used product in addition to these.
4.9.1 Mixing ratio with very short dispensing times
Dual component products usually have different 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
nozzle is essential to the result.
4.9.2 Retraction with dual-component media
Retraction ensures a clean break of the dispensed product. If it is set too large, the
already mixed product enters the dispenser and as the product reacts will plug the
dispenser.
4.9.3 Note the pot life
Before breaks in work, rinsing (filling completely) the mixing nozzle with one of the two
components prevents the two components from reacting inside the mixing nozzle. 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.
