6. Technical functional description
The automatic “touchless” dispensers deliver liquid media using a disposable roller
pump easy to remove and change. The (longer) end of the silicone tube goes into the
supply bottle while the front (shorter) end of the tube, with the dispensing tip clipped
onto it, clicks onto the end of the sensor base plate.
The quantity dispensed with each dose can be adjusted to four different levels.
This is done with the front cover open by simply pressing the round, white set button
above (500 ml dispenser) or to the right (1,000 ml dispenser) of the roller pump:
The factory setting is level 1 = the dispenser delivers
approx. 1.6 ml* of liquid
Pressing the round, white set button (for approx. one second) activates level 2,
indicated by the red LED blinking twice = the dispenser delivers approx. 3.2 ml*
of liquid
Pressing again activates level 3, indicated by the red LED blinking three times =
the dispenser delivers approx. 4.8 ml* of liquid
Pressing again activates level 4, indicated by the red LED blinking four times = the
dispenser delivers approx. 6.4 ml* of liquid
Pressing the set button once more brings the dispenser back to level 1, indicated
by the red LED blinking once
* The dosage can be lower than this when using media of higher viscosity
The dispensers recognize a hand approaching the trigger area by the double sensor
and control electronics (only when the front cover is fully closed) and automatically
trigger a dose.
The full, preset dosage (level 1 = 1.6 ml to level 4 = 6.4 ml) is given without
interruption – it is therefore recommended to use both hands to catch the dose
for levels 2 and up
The sensitive area in which the double sensor triggers the dose can be changed
from the factory setting; instructions for this are available upon request
