Chap 6 ADJUSTMENTS AND SETTINGS
The following adjustment and setting operations may be carried exclusively by qualified
and authorised personnel, paying the utmost care and attention, and taking all
precautions in the event that safety features are bypassed.
6.1 Dispense
r
Before the zeroing operation may be carried out,
dispenser(s) and supply pipes must be filled up. The
zeroing is performed via the adjusting screws which may
be reached by removing the front panel underneath the
tank door.
xThe warranty does not cover damages resulting from improper use of the
dispenser(s) or incorrect manual feed.
xType and dosage of detergent and rinse agent are crucial in affecting the
appliance’s performance and service life. Use only liquid products for industrial
washing with antifoaming agents.
xAdjustments must be made with the appliance hot and correct amount o
f
washing product.
6.1.1 Rinse agent dispense
r
The level of rinse agent 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 and the dispenser, turn on the appliance and start the washing cycle, wait fo
r
approx. 20 seconds and press the “On/off” button for 8-10 times with intervals o
f
approximately 10 seconds. Leave it pressed to let the cycle terminate.
x
Turning the adjusting screw anticlockwise, reduces
the quantity of rinse agent released, while turning it
clockwise, increases the dosage.
xFor 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.
xThe screw adjustment must be refined on the basis o
f
the results obtained after at least three rinsing cycles,
so to let the system settle.
xStriations on washed items and the formation of foam within the washing solution indicate an
excessive quantity of rinse agent. Items covered with water drops and long drying time, indicate

INSTRUCTION MANUAL FOR DISHWASHERS
Page 11 of 12
GB
insufficient amount of rinse agent.
xTo obtain optimum results, use only rinse agents with a manufacturer’s suggested dosage o
f
less than 1.5 gr. /litre.
x7.9 cm of pipe = 1 ml. of product (= 1 gr. of product with a density of 1 kg/dm3). The amount o
f
water used for the rinsing process is approx. 3 litres/cycle.
xDo not modify the height difference between tank and appliance after setting the dosage.
xIf the height difference between tank and base of appliance is more than 80 cm, the dispense
r
may not work correctly.
xIf 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 o
f
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 o
f
water in the tank and the five following rinsing cycles. Fo
r
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 pe
r
rinse per mark, corresponding to approx. 1.2 – 1.8 gr.
of product with density 1.2 kg/dm3). Check the
appliance’s technical specifications to find out about
the amount of water in the tank.
xFor 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.
xThe screw adjustment must be refined on the basis o
f
the results obtained after at least three rinsing cycles,
so to let the system settle.
xAt the end each cycle, no foam must be present in the tank.
xIf 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.
xWith the dispensers supplied, it is necessary to use only detergent with a manufacturer’s
suggested dosage less than 5 gr. /litre.
