7.1.3 Test pump functioning
Set the pause time to "0". The retaining washer must revolve.
Test pump suction function
1.
Pull pump suction hose out of the container.
2. The pump must suck in air, which causes air bubbles in the dosing line.
If no air is being sucked in, the suction function is faulty.
3. The dosing line must then be vented. See Section 5 "Commissioning".
Trouble-shooting
CAUTION!
Fragrance concentrates may be harmful to health!
