Leave the dishes in the basket until they will be dry by
evaporation. Take the dishes away from the basket
and pay attention not to touch the dishes internally on
its border and put them on clean shelves.
In order to continue the washing, load another basket

again.
ACHIEVEMENTS
Any deficiency in the washing process is obvious
when dirty residuals are visible. Any halos might be
caused by an insufficient rinsing: in this case, check
that the rinsing jets are clean and that there is a
sufficient pressure in the water distribution network.
In case you find residuals, check that:
• the washing jets are clean
• there is some detergent
• the pump suction filter is clean
• objects in the rack are placed in a correct position
(SEE PAGE 11).
RINSING ADDITIVES
To grant a perfect rinsing, a quick drying and to avoid
calcareous sediments on glasses and cups you must
add a surfactant on water (Brightener).
Your cleansing agent supplier will be able to suggest
the most suitable product. Your machine is equipped
with a rinse aid dispenser. Mean concentration used
is 0,15 g/lt.
Adding Rinse Aid and Detergent
CAUTION: Only use detergent and rinse aid which
are suitable for commercial washers, a non-foaming
industrial alkaline detergent.
Do not use any soap intended for a residential
dishwasher. This leads to large amounts of foam
building up in the washer and will void your
manufacturers warranty.
CAUTION: Detergents for commercial dishwashers
cause corrosion. Always follow the instructions on the
packaging and drums.
CAUTION: Do not mix different detergent products,
this could cause the dosing pump to break down due
to crystallization.
NSF 3-2009 requirements for detergent and
chemical sanitizer dispensers
Feeders (rinse-aid, or detergent) are OPTIONAL.
When provided see instructions on page 32 in this
manual.
DRAIN PUMP INSTRUCTIONS
(only for machines with drain pump)
The drain pump works automatically only during
the washing cycle to discharge the exceeding water
coming from the rinsing cycle.
At the end of the working day, in order to
completely discharge the tank, it is necessary to
perform the following operations:
1. Open the hood of the dishwasher
2. Remove the overflow pipe from the tank;
3 . Afterwards push button "F" for 3 seconds.
Control lamp "E" and the cycle lamp (the last chosen)
are flashing alternatively.
The discharge will stop automatically after 5 minutes.
Control lamps will stop flashing.
The drain can be stopped at any time by pressing
again button ''F'' .
Please note: in case the hood is open the control lamp
"E" will continue to flash.
Reinstall the overflow and shut the hood.
CLEANSING AGENTS
The choice of a suitable cleansing agent is an
essential condition if you want to obtain extremely
good washing results as regards hygienic results.
That's why it's important to consider some points.
First of all only highly alkaline and chlorine-active
antifoam products, especially made for industrial dish-
washing machines, must be used and they must be
produced by well-known
concentration of the cleansing agents in powder must
be 1,5÷2,5 g/lt. Mean concentration of liquid cleansing
agents must be 2÷4 g/lt.
In order to avoid scales and corrosions, put cleansing
agent above water level on the nearest area of the
sucking pump filter, in this way it will immediately
dilute and will not deposit on the tank bottom.
DESCALING
When hard water is used you can find inside the
machine and also on dishes calcareous sediments
which must be removed both for hygienic and
operating reasons by a descaling operation.
Operating process and frequency of this intervention
are suggested by your cleansing agent supplier who
has suitable products, generally containing phosphoric
acid.
In order to avoid damage to the machine do not
increase the quantities and once operations end rinse
abundantly.
SANIFICATION
At least each 30 days it would be useful to do this
operation which guarantees the complete hygienic
conditions of the machine. We suggest to contact your
cleansing agent supplier who will give you quantity
and name of the most suitable product you can use
and that is generally an active chloride powder
(100÷200 ppm).
In order to avoid damage to the machine do not
increase the quantities and once operations end rinse
abundantly.
