Checking dosing valve
Certain fragrance concentrates cause deposits in the dosing line and in the dosing valve. This may interfere
with the fragrance dosing.
Check the dosing valve every 6 months or as required
1.
When refilling the fragrance concentrate allow the pump to suck some air in.
2.
Observe the air bubble when the fragrance pump is operating.
3.
If the air bubble in the suction pressure hose is transported further, the fragrance dosing is functioning
correctly. If the air bubble moves back and forth, the dosing valve is blocked and must be cleaned.
Clean dosing valve
1.
Release the dosing hose from the dosing valve.
2.
Unscrew the dosing valve.
3.
Wash the dosing valve out with warm water or rinse it with methylated spirit.
4.
If this proves unsuccessful, renew the valve.
