C GENERAL DESCRIPTION OF MACHINE

C1 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:

200 racks/h 250 racks/h

Figure 6 View of different configurations of compact rack-type dishwashers

ENGLISH

C2 Description of machine modules

The machine consists of the following zones:

• wash zone

• rinse zone and can be integrated with the following units:

•prewash zone

• energy recovery/steam suppression unit (CU)

• drying zone (DT).

C2.1 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 55-65 °C (71-78 °C ETL-S version).

C2.2 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. 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.

C2.3 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.

C2.4 Energy recovery/steam suppression unit (CU)

Some rack-type dishwasher versions can be supplied with an energy recovery/steam suppression unit called a condensing unit (CU). It consists of a fan and an air-water heat exchanger. By means of the fan, the steam present inside the wash zone is exhausted and condensed thanks to the heat exchange with the cold water entering; the condensed steam (water) is recovered in the wash tank. This also offers the advantage of heating the cold water entering, recovering a part of the heat that would otherwise be dissipated into the environment.

C2.5 Drying zone (DT)

The dishes come under a flow of hot air in the drying zone, facilitating the water evaporation process. Drying occurs with hot air at a temperature of 50-60 °C. This function can be added at the machine outfeed after the rinse zone.

C2.6 View of module composition

In rack-type dishwashers the various zones just described are thus applied to the various previously defined configurations.

D2 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.

E TRANSPORT, HANDLING AND STORAGE

E1 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.

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 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 haz-

ard.

E1.1 Transport: Instructions for the carrier

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 suf-

ficient to keep it steady. The transported load can shift:

- when braking;

- when accelerating;

- in corners;

- on particularly rough roads.

• handle the machine, keeping it at minimum height from the ground.

CAUTION! For machine lifting, do not use movable or weak parts such as casings, electrical raceways, pneumatic parts, etc., as anchoring points.

E2.2 Translation

The operator must:

• have a general view of the path to be followed;

• stop the manoeuvre in case of hazardous situations.

E2.3 Placing the load

Before placing the load make sure the path is free and that the floor is flat and can take the load.

E3 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 and 50°C.

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! 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.

E2 Handling

Arrange a suitable area with flat floor for machine unloading and storage operations.

E2.1 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;

F INSTALLATION AND ASSEMBLY

IMPORTANT

IMPORTANT! Machine installation operations must

only be carried out by specialized Technicians provided with all the appropriate personal protection equipment (safety shoes, gloves, glasses, overalls, etc.), tools, utensils and ancillary means.

I GENERAL SAFETY RULES

I1 Introduction

The machines are provided with electric and/or mechanical safety devices for protecting workers and the machine itself. Therefore the user must not remove or tamper with such devices.

The Manufacturer declines any liability for damage due to tampering or their non-use.

I1.1 Protection devices installed on the machine

I1.1.1 Guards

The guards on the machine are:

- fixed guards (e.g. casings, covers, side panelling, etc.), fixed to the machine and/or frame with screws or quick-release couplings that can only be removed or opened with tools;

- interlocked movable guards (front panels) for access to inside the machine;

- access doors to the machine’s electrical equipment, made from hinged panels openable with tools. The door must not be opened during machine movement, if inside the door there is equipment that is hazardous when live or under pressure.

IMPORTANT! Several illustrations in the manual repre-

sent the machine, or parts of it, without guards or with guards removed. This is purely for explanatory requirements. Never operate the machine without the guards or with the safety devices deactivated.

I1.1.2 Safety devices

The machine has:

- interlocks on the front panels giving access to inside the machine;

- emergency stop push buttons (recommended) and end limit switches must be installed on the rack handling tables in case the racks exceed their travel.

I1.2 Safety signs to be displayed on the

machine

PROHIBITION MEANING

Do not oil, lubricate, repair and adjust moving parts.

Do not remove the safety devices.

Do not use water to extinguish fires (shown on electrical parts).

DANGER MEANING

DANGER OF CRUSHING HANDS

DANGER OF BURNS

DANGER OF ELECTROCUTION (shown on electrical parts with

WAR NING ! Do not remove, tamper with or make the

labels on the machine illegible.

I2 Decommissioning

When the machine is no longer to be used, make it unusable by properly disconnecting the incoming power and water supplies.

I3 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.

IMPORTANT! Machine maintenance operations must

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.

I4 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 damage to the system are not allowed.

Improper use includes:

• failure to disconnect the power supply with the main switch in “O” off position before carrying out adjustment, cleaning, resetting and maintenance operations;

• failure to disconnect the power supply with the main switch in off position “O” at the end of the day;

• lack of machine maintenance, cleaning and periodical checks;

• structural changes or modifications to the operating logic;

• tampering with the guards or safety devices;

• failure to use personal protection equipment by operators, specialized technicians and maintenance personnel;

• failure to use suitable accessories (e.g. use of equipment, ladders, etc., unsuitable for carrying out maintenance on equipment positioned inside the machine);

• keeping combustible or flammable materials, or in any case materials not compatible with or pertinent to the work, near the machine;

• incorrect machine installation (see chapter E “Installation and assembly”);

• placing in the machine any objects or things not compatible with washing or that can obstruct/damage the machine or persons or pollute the environment;

• non-compliance with the requirements for correct machine use;

• other actions that can cause risks not eliminable by the Manufacturer.

I5 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.

J4.2 Exterior cleaning

Clean the stainless-steel surfaces with lukewarm soapy water (do not use detergents containing abrasive substances, steel wool, brushes or scrapers in common steel) then rinse with a wet cloth and dry carefully.

J5 Long idle periods

Whenever the machine is not going to be used for a long period of time (e.g. one month), carefully carry out the following instructions.

• Completely empty the tanks as indicated in par. J3.6 Drain or Clean function.

• After draining the tanks, press the On/Off key (“A” Table 2 Control panel) to switch off the dishwasher.

• Disconnect the electrical cable.

• Close the water supply valves.

• Clean the inside and outside of the machine as indicated in par. J4.1 Daily internal cleaning and J4.2 Exterior cleaning.

When using the machine again, follow the indications in par. J3 Daily activation of machine.

J6 Maintenance

Before servicing, disconnect the electrical main switch 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 booster, 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.
