Initial Start-up and Material Change
* The unit will be delivered with a testing-liquid filled in!
Observe at
the first start-up
* or at

(Please pay attention to
section 3
and
Section 7.1 - 7.5!
)
One-time procedure to clean up the hoses and the dosing pump:
Place an empty bowl under the mixing head without mixing tip. The quantity flow
controllers are located behind the both-sided bores of the hood. Turn both quantity flow
controllers 2 ½ to 3 to the left from the closed position (stop far right) to the open position
by using a screwdriver.
Now press the red button and hold it down until both components run out of the openings
simultaneously and without air bubbles.
Afterwards close the quantity flow controller and check the mixing ratio . If it is not 1:1 ,
there is the possibility to reduce the quantity flow of the component that is delivered too
much. Therefore open the quantity flow controller of that component in small steps (from 2
turns to the left in 1/8-turns) in order to optimize the mixing ratio. After each adjustment, a
re-inspection is necessary.
