5.3.5 Shut-Off Delay (3 - 30 sec.)
Shut-off delay = the amount of time between switching the connected electrical appliance off and the
closure of the respective suction hose (= pinch valve).
Two types of shut-off delay times can be distinguished, each of which can be set independently of one
another:
• Only one of the two suction hoses, A OR B, is open:
Set the time, from when the pinch valve in the suction hose closes and the suction turbine shuts off
(e.g. for targeted suction of residue dust).
• Both suction hoses, A AND B, are open:
Set the duration of time, until the pinch valve in the suction hose closes and the suction power for the
other suction hose has readjusted.
Select a longer amount of time in order to prevent short interruptions (e.g. when working with a
hand piece motor) from switching the extractor on and off too frequently, therefore causing the
suction power to be continuously be readjusted.
⇒ Press the menu key (30) 5 x.
