insufficient amount of rinse agent.
x
To obtain optimum results, use only rinse agents with a manufacturer’s suggested dosage of
less than 1.5 gr. /litre.
x
7.9 cm of pipe = 1 ml. of product (= 1 gr. of product with a density of 1 kg/dm
3
). The amount of
water used for the rinsing process is approx. 3 litres/cycle.
x
Do not modify the height difference between tank and appliance after setting the dosage.
x
If the height difference between tank and base of appliance is more than 80 cm, the dispenser
may not work correctly.
x
If rinse aid is not used, completely close the dispenser adjustment screw.
6.1.2 Models with no detergent metering unit
Manual feed is discouraged
as it does not guarantee
the optimal results offered by an automatic system. If,
however, an automatic dispenser is not used, introduce
the detergent in the pump intake filter area every five
cycles, in the dosage suggested by the manufacturer of
the detergent. Refer to the technical specifications to find
out the amount of water used in the tank; the quantity
used for rinsing is approx. 3 litres. At every top-up, add a
quantity of detergent corresponding to the quantity of
water in the tank and the five following rinsing cycles. For
following dosages only add the amount of detergent
required for rinsing operations.
The installation of a detergent dispenser is always recommended.
6.1.3 Models with detergent dispenser (available on request)
The level of detergent inside the container must be adequate; it must never be
completely emptied, or topped-up with corrosive or impure products. To fill up the supply
pipe it is sufficient to turn on the appliance and perform the first loading with the unit connected.
x
Turning the adjusting screw anticlockwise decreases
the amount of detergent released, while turning it
clockwise, increases the dosage (from 1 to 1.5 ml per
rinse per mark, corresponding to approx. 1.2 – 1.8 gr.
of product with density 1.2 kg/dm
3
). Check the
appliance’s technical specifications to find out about
the amount of water in the tank.
x
For a rough estimate concerning the amount of rinse
agent required for the first zeroing operation, refer to
the dosage suggested by the manufacturer of the
product.
x
The screw adjustment must be refined on the basis of
the results obtained after at least three rinsing cycles,
so to let the system settle.
x
At the end each cycle, no foam must be present in the tank
.
x
If foam is present, first check the type of detergent used and eventually replace with a more
adequate one. If foam is still present, check the water temperature in the tank is correct and
eventually reduce the dosage of detergent until all foam is successfully eliminated.
x
With the dispensers supplied, it is necessary to use only detergent with a manufacturer’s
suggested dosage less than 5 gr. /litre.
