4.4 Rinse aid use
The machine has a standard rinse aid dispenser. The machine automatically sucks the product.
The rinse-aid chemical, shall be suitable for professional glass and dishwashers.
The recommended amount is 2-5 cm of product measured on the suction hose.
1 cm of the product drawn into the hose is equal to about 0.13g. A correct amount of rinse aid
is very important for a quick and proper drying.
N.B.:
Excessive amount of chemicals or foam will reduce wash pump effi ciency.
Should the detergent lack, the display will show

(only with optional "Sensor
for Chemicals Low Level").

tank, with coarse salt (0,500 kg - 1-4 mm. grains), being careful not to spill it into the sump. A
strong concentration of salt can negatively aff ect the correct functioning and service life of the
machine and generate rust and the steel oxidation. After fi lling with salt, lock the plug tightly.
