Adjustments: For each rinse cycle, the rinse aid draws a quantity of rinse aid product.
In the hydraulic dosing, the minimum flow rate is obtained by turning the adjustment screw clockwise, while the maximum flow
rate is obtained by turning it anti-clockwise.
In the peristaltic dosing, the minimum flow rate is obtained by turning the adjustment screw anti-clockwise, while the maximum
flow rate is obtained by turning it clockwise.
The dispenser is pre-set to intake approximately 5 cm of hose (0.70g.) Too much rinse aid would leave the dishes streaky and
would generate foam in the wash tank.
Dishes with drips of water and rather slow drying time mean that the quantity of rinse aid is insufficient.
Before you establish the correct quantity of the surfactant, you should test the hardness of the water in advance.
(If the hardness of the water is above 12°f, you need to install a softener upstream from the supply solenoid valve of the machine,
a part on models with water softener, does not belong to models with water softener please refer to section 2.1 "Technical
Specification".
Seeing as the quantity varies considerably based on the concentration of the product and on the formula, the quantities that
we have given are merely indicative and are just a rough idea.
To dispense the exact quantity of product, once intaken, take the clear hose out of the surfactant container and measure the
movement of the water column inside it.
3.2 DETERGENT QUANTITY – MANUAL DISPENSING
Following the instructions of the detergent supplier, put the required quantity of liquid detergent into the wash tank, which is
approximately 20g every 5 wash cycles. The quantity may vary according to the type and quantity of water. Use exclusively
specific foam-inhibitor detergents, in the concentrations indicated.
Ask a specialist in chemical products for the correct choice of products to use and their quantities.
3.3 DETERGENT QUANTITY – BY DOSING
In the detergent peristaltic dosing (1) the minimum flow rate is obtained by turning the adjustment screw anti-
clockwise, while the maximum flow rate is obtained by turning it clockwise; bear in mind that 1 g. of detergent
takes up a volume of approximately 8 cm of hose.
Make sure the RED product intake hose is inserted into the detergent tank and that the little filter has been
installed as well as the weight on the hose (2). For the type and quantity of detergent to use, ask your supplier
of chemical products. Too much detergent will not only generate foam in the wash tank, but will also leave the
dishes streaky.
4 - PREVENTIVE CHECKS
Check the following before using the machine:
The filling solenoid valve should start to work again when the level of water is 2 cm. above the heating element in the
tank. WASHING AND RINSING ARMS
The washing and rinsing arms must turn freely without any interference and all the nozzles must work
correctly. TEMPERATURES
The temperatures of the rinse and washing water must be those written on the
table. DISPENSERS
For each cycle, the dispensers should intake the correct amount of rinse aid liquid and detergent (where fitted).
WASHING RESULTS
The washing results should ensure that every possible trace of solid waste has been removed from the surface of the dishes.
At the end of the cycle, the perfectly clean dishes should dry in few minutes through evaporation once the basket is taken out

HYDRAULIC
Rinse aid dosing, it exploits the
rinsing pressure to activate itself. To
enable it, simply start the machine
and run some complete wash
cycles.
Rinse aid pipe with weight and filter: Make sure the CLEAR product hose is inserted into the
container of the rinse aid products and the little filter is installed and also the weight on the hose.
Attention: red pipe is referred to detergent, see section 3.3
WATER LEVEL
While the wash tank is filling, the water should
stop flowing when its level is at least 1 cm. from
the spill level of the overflow pipe.
(please refer to section 2.1 "Technical Specification").
(please refer to section 2.1 "Technical Specification").
PERISTALTIC
Rinse aid dosing, it exploits the rinsing
pressure to activate itself. To enable it,
simply start the machine and run some
complete wash cycles.
