GENERAL DESCRIPTION OF MACHINE
General description
The rack-type dishwasher is suitable for washing dishes, glasses, cups, cutlery, trays, containers and receptacles in
plastic and/or steel used for preparing, cooking and serving; as well as various cooking utensils in ceramic and/or metal.
The machine is designed for the above-mentioned applications. Under no circumstances may the machine be used for
other applications or ways not provided for in this manual.
This equipment has been produced to meet the needs for a better work environment and economical efficiency. These
dishwashers are used in restaurants, cafeterias, cooking centres and large institutions.
The special dish racks, that can be equipped with various inserts, offer practical and easy use for obtaining excellent
washing results. Rack handling inside the machine occurs automatically. The electronic system enables complete
supervision of the washing process. The control panel also has a display that shows the operating parameters and signals any anomalies.
In this type of machine the rack is taken from the loading point to the unloading point, through the various washing functions. Systems for scraping and wetting the dishes (e.g. manual prewash spray) and areas for sorting and arranging
them in the racks must be arranged ahead of the dishwasher.
The possible configurations of compact rack-type dishwashers, classified according to the maximum number of racks
washed in one hour, are as follows:

B2.1
ENGLISH
The machine consists of the following zones:
• wash zone
• rinse zone
and can be integrated with the following units:
• prewash zone
Wash zone
Water with the addition of detergent is sprayed on the dishes in the wash zone through an upper and lower wash arm
system. The purpose of this function is to remove all residuals of food from the dishes. Washing is carried out with water
circulating at a temperature of 71-78 °C / 160-172 °F.
B2.2
Rinse zone
Water with the addition of rinse aid is sprayed on the dishes in the rinse zone through a system of arms equipped with
special nozzles. The purpose of this function is to remove all residuals of detergent deriving from the previous wash
phase.
Rinsing is carried out with clean water coming from the water system, heated to a max. temperature of 82-90 °C / 180194°F.
The high temperature ensures satisfactory drying and careful neutralization of bacteria. The addition of rinse aid allows
the water to easily run off the dishes, thus favouring the drying process.
B2.3
Prewash zone
Water is sprayed on the dishes in the prewash zone through an upper and lower prewash arm system. The purpose of
this function is to remove the larger food residuals, preparing the dishes for the subsequent wash phase.
Prewash is carried out with water circulating at a max. temperature of 40°C / 104°F in order to prevent food residuals (in
particular proteins) from sticking to the dishes.
B2.4
View of module composition
In rack-type dishwashers the various zones just described are thus applied to the various previously defined configurations.

TRANSPORT, HANDLING AND STORAGE
Introduction
Transport (i.e. transfer of the machine from one place to
another) and handling (i.e. transfer inside workplaces)
must occur with the use of special equipment of adequate capacity.
The machine can be transported by road, rail, sea or air.
Except for transport by road, the machine is placed
inside a container in which there are also other
machines. The machines can be positioned inside the
container by the Manufacturer or by the carrier.
IMPORTANT!
Due to its size, during transport one
machine cannot be stacked on top of
another, therefore possible risks of load
overturning are excluded.
The Manufacturer declines any liability for possible damage to the packing and the machine.
On receiving the machine, check that the packing and
components are not damaged. In case of damage,
immediately notify the carrier and the Manufacturer.
If the equipment received has visible or hidden damage,
a claim can be made with the carrier.
Visible losses or damage must be reported in the transport document at the time of delivery. The transport document must be signed by the carrier’s representative
(e.g. the driver). If the transport document is not signed,
the carrier can reject the claim.
The request for inspection must be submitted to the carrier within 15 days in case of non-visible damage or
losses detected only after unpacking the equipment. The
carrier shall arrange an inspection. Keep all the packing
material and contents. Under no circumstances may a
damaged appliance be returned to the manufacturer
without prior notice and written permission.
The machine must only be transported, handled and
stored by qualified personnel, who must have:
- specific technical training and experience;
- knowledge of the safety regulations and applicable
laws in the relevant sectors;
- knowledge of the general safety provisions;
- the ability to recognize and avoid any possible hazard.
The Manufacturer declines any liability whenever transport is undertaken by carriers chosen by the Customer.
14
IMPORTANT!
Machine transport, handling and storage
personnel must receive adequate
instruction and training on the use of lifting systems and the use of personal protection equipment suitable for the type
of operation performed (e.g. overalls,
safety shoes, gloves and helmet).
D1.1
Transport: Instructions for the carrier
During the journey the tightness of the fixing systems
must be checked several times, and in particular:
• just a few km after the start of the journey;
• in case of sudden temperature changes;
• in case of intense cold;
• in case of particularly rough roads.
When removing the anchoring systems, make sure the
stability of the machine parts does not depend on the
anchoring and, therefore, that this operation does not
cause the load to fall off the vehicle.
WARNING!
Do not stand under suspended loads
during the loading/unloading phases.
Unauthorized personnel must not
access the work zone.
IMPORTANT!
The machine’s weight alone is not sufficient to keep it steady.
The transported load can shift:
- when braking;
- when accelerating;
- in corners;
- on particularly rough roads.
If slings in synthetic fibre are used to anchor the
machines, protect them from friction, abrasion and damage caused by possible sharp edges of the load. If there
are sharp edges that can damage the sling, use suitable
corner protectors or sliding tubes.
CAUTION!
When removing the anchoring systems,
make sure the stability of the machine
parts does not depend on the anchoring
and, therefore, that this operation does
not cause the load to fall off the vehicle.
Before unloading the machine components make sure all the anchoring systems are removed.
Handling
Arrange a suitable area with flat floor for machine
unloading and storage operations.
D2.1
Procedures for handling operations
For correct and safe lifting operations:
• use the type of equipment most suitable for characteristics and capacity (e.g. lift trucks or electric pallet
truck);
• cover sharp edges;
• check the forks and lifting procedures according to
the instructions given on the packing.
Before lifting:
• send all operators to a safe position and prevent persons from accessing the handling zone;
• make sure the load is stable;
• make sure no material can fall during lifting, and
manoeuvre vertically in order to avoid impacts;
• handle the machine, keeping it at minimum height
from the ground.
IMPORTANT!
Machine positioning, installation and
disassembly must be carried out by a
specialized technician.
IMPORTANT!
Do not make modifications to the parts
supplied with the machine. Any missing
or faulty parts must be replaced with
original parts.
CAUTION!
For machine lifting, do not use movable
or weak parts such as casings, electrical
raceways, pneumatic parts, etc., as
anchoring points.
D2.2
Translation
The operator must:
• have a general view of the path to be followed;
• stop the manoeuvre in case of hazardous situations.
D2.3
Placing the load
Before placing the load make sure the path is free and
that the floor is flat and can take the load.
D3
Storage
The machine and/or its parts must be stored and protected against damp, in a non-aggressive place free
of vibrations and with room temperature of between 10°C / 14°F and 50°C / 122°F.
The place where the machine is stored must have a flat
support surface in order to avoid any twisting of the
machine or damage to the support feet.
IMPORTANT!
During the storage phase the machine
can be stacked on another as shown in
the pictogram on the packing.

Instructions for use and maintenance
Risks mainly of a mechanical, thermal and electrical
nature are present in the machine.
Where possible the risks have been neutralized:
• directly, by means of adequate design solutions,
• or indirectly by using guards, protection and safety
devices.
Any anomalous situations are signalled on the control
panel display.
During maintenance several risks remain, as these could
not be eliminated and which must be neutralized through
specific behaviour and precautions.
Do not carry out any control, cleaning, repair or maintenance operations on moving parts.
Workers must be informed of the prohibition by means of
clearly visible signs.
To guarantee machine efficiency and correct operation,
periodical maintenance must be carried out according to
the instructions given in this manual.
In particular, make sure to periodically check correct
operation of all the safety devices and the insulation of
electrical cables, which must be replaced if damaged.

only be carried out by specialized Technicians provided with all necessary personal protection equipment (safety
shoes, gloves, glasses, overalls, etc.),
tools, utensils and suitable ancillary
means.
WARNING!
Never operate the machine by removing,
modifying or tampering with the guards
and protection or safety devices.
IMPORTANT!
Before carrying out any operation on the
machine, always consult the manual
which gives the correct procedures and
contains important information on
safety.
H4
Improper use
Improper use is any use differing from that specified in
this manual. During machine operation, other types of
work or activities considered improper and that in general can involve risks for the safety of operators and

Maintenance
IMPORTANT
Before servicing, disconnect the electrical service
and place a red tag at the disconnect switch to indicate work is being done on that circuit.
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 prewash, wash and rinse
jets with vinegar or scale remover.
• Once or twice a year clean the finned coil of the CU
(call technical assistance).
It is also advisable to stipulate a scheduled preventive maintenance contract with technical assistance.
I6.1
Preventive maintenance
The preventive maintenance call can be activated (call
technical assistance).
On reaching the set number of working hours (e.g.
5000), a technical assistance call message appears on
the display.
This message suggests calling a specialized technician,
for a general check of the equipment.

dirty.
2. Make sure the wash jets are not clogged by solid
residuals.
3. Make sure the initial quantity of detergent and/or
subsequent additions are correct.
4. Make sure the modules making up the machine
respect the recommended values given in the
technical data table.
5. Make sure the dishes are correctly placed in the
racks.
GLASSES AND DISHES ARE NOT PROPERLY
DRIED
1. Make sure there is rinse aid in the container and
top-up if necessary.
2. Make sure the water temperature of the rinse module is between 176°F and 194°F (80°C - 90°C).
3. If present in the machine, check operation of the
drying module (that hot air comes out).
4. Make sure the curtains are correctly positioned.
5. Make sure the dishes were not immersed in foamy
detergent (e.g. hand wash detergent) before being
put in the machine.
CONDENSATE ON GLASSES
1. Make sure there is rinse aid in the container and
top-up if necessary.
STAINS ON GLASSES
