ATTENTION! MACHINE LIVE: Remove the front panel of the dishwasher to adjust the dispensers.
3.1 RINSE AID QUANTITY – RINSE AID DISPENSER
The rinse aid dispenser is always installed and there are two types: hydraulic (3) or peristaltic (1). They both work
automatically.
The hydraulic dispenser (3) exploits the rinsing pressure to activate itself, while the peristaltic dispenser (1) is
electrically operated.
Make sure the CLEAR product suction hose is inserted into the container of the rinse aid products and that the little
filter is installed and also the weight on the hose (2).
To enable it, simply start the machine and run some complete wash cycles.
Adjustments: For each rinse cycle, the rinse aid draws a quantity of rinse aid product.
In the peristaltic dispenser (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.
In the hydraulic dispenser (3), the minimum flow rate is obtained by turning the adjustment screw clockwise, while
the maximum flow rate is obtained by turning it anti-clockwise.
The dispenser is preset 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).
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 OR USING A DISPENSER (OPTIONAL)
MANUAL
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.
LIQUID DETERGENT DISPENSER (OPTIONAL)
In the detergent dispenser (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 dishwasher:
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 device.
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.
DISPENSER
For each cycle, the dispenser should intake the correct amount of rinse aid and/or detergent.
