4. Function
The dosing unit DUFTDOS UNPL with contact sensor measures the temperature at the steam tube by an incl. temperature sensor. The dosing
operation is released if the temperature has reached 70°C (ex works adjustment). After you press the push button the dosing is activated for
0,5 seconds till 5 seconds (adjustable) and aroma is injected into the steam pipe. Afterwards the dosing is locked for an adjustable (1-20
minutes) pause time.
If the temperature will get lower than 65°C the pump switches off automatically. Therefore, no fragrance can be dosed when the system is
stopped. This "switch temperature" can be adjusted. Look at section 11.
-If the temperature will fall below the adjusted temperature the LED illumination of the button flashes (off + on 50% dimmed) in an
Interval of 1 second. If the LED flashes the aroma dosing is deactivated.
-If the adjusted temperature will be reached the LED shines 50% dimmed and the aroma pump is ready for activation.
-If the button will be pressed, the LED illumination of the button flashes (100% + 50% dimmed) in an interval of 1 second and at the
same time aroma will be dosed for the adjusted time. After the lapse of the pause time the LED shines 50% dimmed and the aroma
pump is ready for a new activation with the push button

6. Fragrance pump
A peristaltic dosing pump is used for dosing, which safely promotes also smallest quantities. Even
when Air- or gas-bubbles are trapped in the suction line. Rotating rolls press the dosing hose
against the pump tube housing, whereby the liquid within the hose is pressed out in front of the
rolls and at the same time drawn in behind them. The pump is extremely reliable and very
simple to handle.
Fragrance concentrates are very aggressive. The used dosing hose is resistant against most
concentrates that are in common use in the industry but we still recommend to check with your
equipment supplier prior to use.
Attention!
-Back pressure must not be higher than 0.5 bar
-Use only original WDT dosing valves.
-Don´t bend the dosing tube.
-Use only PTFE dosing tube.
Company WDT can take no warranty for the resistance of the hose against every fragrance concentrate on the
market!
