Standard cycle time may vary should the inlet water temperature be different from that indicated above.
C2 Characteristics of power supply
The AC power supply to the machine must meet the following conditions:
• max. voltage variation ± 10%
• max. frequency variation ± 1% continuous ± 2% for a short period.
Harmonic distorsion, unbalanced three-phase supply voltage, voltage pulses, interruption, dips and the other electric
characteristics must respect the provisions of point 4.3.2 of Standard EN 60204-1 (IEC 60204-1).
IMPORTANT!
The machine’s power supply must be protected against overcurrents (short circuits and over-
loads) by fuses or suitable thermal magnetic circuit breakers.
These must be fitted on an omnipolar disconnection system having a contact gap of at least 3 mm.
IMPORTANT!
For protection against indirect contacts (depending on the type of supply provided for and con-
nection of earths to the equipotential protection circuit) refer to point 6.3.3 of EN 60204-1 (IEC
60204-1) with the use of protection devices that ensure automatic cut-off of the supply in case of
isolation fault in the TN or TT systems or, for IT systems, the use of isolation controllers or differential current protection devices to activate automatic power disconnection (an isolation controller must be provided for indicating a possible first earth fault of a live part, unless a protection
device is supplied for switching off the power in case of a such a fault. This device must activate
an acoustic and/or visual signal which must continue for the entire duration of the fault).
For example: in a TT system, a differential switch with cut-in current (e.g. 30 mA) coordinated
with the earthing system of the building where the machine is located must be installed ahead of
the supply.
IMPORTANT!
Customers are requested to follow these instructions, otherwise the Manufacturer does not guar-
antee the machine for continuous operation and/or against faults.

IMPORTANT
The GUARANTEED RINSE SYSTEM (GRS) is incorporated in the ACTIVE/ WASH SAFE CONTROL models
(see led “P”). The GRS is an automatic rinse time/temperature control system.
Operation is as follows:
• during the wash cycle the indicator light is OFF;
• during the rinse cycle the indicator light comes on and is GREEN;
• at the end of the rinse cycle the indicator light remains GREEN if the rinse temperature and time have
been carried out as per the programme, otherwise the indicator light becomes RED;
• upon opening the hood, the indicator light GOES OUT.
If the indicator light becomes RED, for example should the boiler waiting time be disabled, wait for a couple of minutes and then repeat the wash cycle.
The temperature shown on the display is that of the tank if the light “D” is on, or of the boiler if the indicator light
“F” is on. The tank temperature is displayed during the wash cycle and the boiler temperature during the rinse
cycle.
In automatic versions the machine has a LED bar "Q" which monitors equipment status. When the LED bar is
green the machine is ready for washing and when it is blue it indicates wash cycle progress status. After rinsing,
the LED bar remains green if the temperature and rinse time were as programmed, otherwise the LED bar turns
RED.

External dispenser adjustment
IMPORTANT
With external dispensers, it may be more useful to
have the parameters expressed in seconds, setting the
parameter to =seconds. In this way the
value of the parameters represents the duration in
seconds.
Listed below are special values usable when external
automatic dispensers are connected to the equipment:
-if the detergent dispenser only
operates during wash pump operation; terminals
7-9 of the main terminal board are powered at the
same time.
-if the detergent dispenser only
operates during filling electrovalve operation for
restoring the boiler level; terminals 7-9 of the main
terminal board are powered at the same time.
-if the rinse-aid dispenser only
operates during filling electrovalve operation for
restoring the boiler level; terminals 8-9 of the main
terminal board are powered at the same time.
-if the rinse-aid dispenser only operates
during wash pump operation; terminals 8-9 of the
main terminal board are powered at the same time.
For connections, see the wiring diagram.
The mixing of different types of detergent/rinse-aid
will cause crystallisation, which may result in a
breakdown of the dosing pump. Failure to observe
this condition will invalidate the guarantee and
product liability.
Example 1:
Supposing that an external detergent dispenser has
been connected with a tank concentration measuring
sensor, a standard setting could be as follows:
•
the parameter value is in seconds.
• the dispenser is not activated during fill-
ing of the tank.
• the dispenser is activated during
wash pump operation and, according to the concentration of detergent detected by the sensor, the
correct amount of detergent is dispensed.
Example 2:
Supposing that an external rinse-aid dispenser has
been connected with a tank concentration measuring
sensor, a standard setting could be as follows:
• the parameter value is in seconds.
• the dispenser is activated at each wash
cycle simultaneously with operation of the filling
solenoid valve. In this way avoiding modifications to
the wiring of the machine.
Suggestion: to check the effectiveness of the rinseaid, look at freshly washed glasses against the light.
Drops of water remaining on the glass indicate an
insufficient amount while streaks indicate an excess.
Changing the detergent/rinse-aid type.
If changing to a different detergent/rinse-aid type
(even one by the same manufacturer), you must rinse
the suction and pressure hoses with fresh water before
connecting the new detergent/rinse-aid container.

DESCRIPTION OF HAZARDOUS SITUATION
The operator can slip due to water or dirt
on the floor.
The operator deliberately or unintentionally touches some components inside the
machine or dishes at the outfeed without
using gloves or without allowing them to
cool.
Contact with live parts during maintenance operations carried out with the
electrical panel powered. The operator
intervenes (with a power tool or without
disconnecting the power to the machine)
lying down on the wet floor.
The operator intervenes on the machine
using unsuitable systems to access the
upper part (e.g. rung ladders, or climbs
on it).
During maintenance on the machine or
the packing containing the machine with
the use of unsuitable accessories or lifting systems or with load unbalanced.
Contact with chemical substances (e.g.
detergent, rinse aid, scale remover, etc.)
without taking adequate safety precautions. Therefore always refer to the safety
cards and labels on the products used.
Possible risk of injury to upper limbs
during the hood closing operation.
Table 3 Residual risks
H5 Residual risks
The machine has several risks that were not completely eliminated from a design standpoint or with the
installation of adequate protection devices.
Nevertheless, through this manual the Manufacturer
has taken steps to inform operators of such risks, carefully indicating the personal protection equipment to be
used by them.
Sufficient spaces are provided for during the machine
installation phases in order to limit these risks.
To preserve these conditions, the corridors and areas
around the machine must always be:
• kept free of obstacles (e.g. ladders, tools, containers, boxes, etc.);
• clean and dry;
• well lit.
For the Customer’s complete information, the residual
risks remaining on the machine are given below; such
actions are to be considered incorrect and therefore
strictly forbidden.

Insert the Delime tube present in the machine,
identified by an appropriate label, in a container
with at least 2l of wine vinegar 6% (2l is the minimum amount of vinegar needed for a correct
Delime cycle)
.
The appliance will not remove burnt food deposits
from dishes. Dishes with burnt-on food deposits
should be cleaned mechanically/chemically (for
example, pre-wash under running water) before
putting them in the dishwasher.
The use of “foaming”/non-specific detergents or in
any case detergents used in different ways from that
prescribed by the manufacturer, can cause damage
to the dishwasher and compromise washing results.
Failure to remove the residuals of detergent possibly
used for manual prewash can cause malfunctioning
of the dishwasher and compromise washing results.
Change the water in the tank at least once a day.
Type of racks and loading
• YELLOW rack: for 18 plates with maximum diameter of 240 mm.
Figure 23 YELLOW rack
• GREEN rack: for 12 bowls with maximum diameter
of 240 mm.
Only use wine vinegar (with 6% of acetic acid) and not
other descaling substances. Descaling with the use of
chemical substances other than vinegar must only be
done by a specialized technician.
• Remove the basket with dishes and remove the overflow "2" (see Figure 17 Filters and overflow).
• Close the hood.
• Activate the delime cycle by pressing the button "N"
(see Ta bl e 2 Control panel) for at least 5 seconds.

I8 Hood type dishwasher with incorporated
continuous water softener
These models have a continuous softener in the
dishwasher water circuit. By means of special resins,
this device removes the calcareous substances from
the feed water, supplying decalcified water for
washing.
For the continuous softener to work properly the resins
must be regenerated periodically, with frequency
depending on the hardness of the water and the number of wash cycles carried out.
Unlike conventional water softeners, this continuous
softener does not require machine stops for regenerating the resins.
Check if the overflow has been
removed.
Check for obstruction on the
waste outlet pipe and the
overflow aperture.
Check for obstruction on the

The water can only be softened if there is salt in the
special container. The salt container must be filled
when the dishwasher is started the first time and
whenever the message
appears and an
audible alarm sounds.
No salt in the container
IMPORTANT:
Only use coarse salt with a purity level of
99.8% NaCl. The use of salt with a lower
purity level can cause clogging of the salt
container filter and malfunctioning of the
water softener.
When the salt container is empty, the message
appears on the display and an audible alarm

I11 Maintenance
Inspection and maintenance intervals depend on the
actual machine operating conditions (total wash hours)
and ambient conditions (presence of dust, damp, etc.),
therefore precise time intervals cannot be given. In any
case, to minimize interruptions of the service, careful
and periodical machine maintenance is advisable.
Therefore, it is advisable to:
• Descale the boiler, inside surfaces of the tank and
the machine piping once or twice a year (call technical assistance).
• Every month descale the wash and rinse jets with
vinegar or scale remover.
• The internal hose of the rinse-aid and detergent
peristaltic dispenser should undergo periodic maintenance (once or twice a year).
• If present, clean the finned coil of the energy saving
device once or twice a year (call technical assistance).
It is also advisable to stipulate a scheduled preventive maintenance contract with technical assistance.
I11.1 Preventive maintenance
The preventive maintenance call can be activated (call
technical assistance).
On reaching the set number of cycles (e.g. 20000), a
technical assistance call message appears on the display.
This message suggests calling a specialized technician, for a general check of the equipment.
