Adjusting the rinse aid
dosage
According to the finish and drying results
obtained, adjust the dose of rinse aid by
turning the dispenser's selector to the
desired position (min-max): the amount of
rinse aid dispensed is proportional to the
selector position.
The dose is factory set in medium position.
Increase the dose if there are drops of
water or lime spots on the dishes after
washing.
Reduce it if there are sticky whitish streaks
on the dishes or a bluish film on glassware
or knife blades.
