We recommend to buy exclusively crockery and cutlery suitable for dishwashing. After several washes, the glass can become opaque.

It is mandatory to repeat the washing cycle if at the end of the cycle the crockery are not well clean or if there are washing residues (glasses, cups, bowls, etc. with liquid inside).

• Place the crockery with deep hollow with upper face downwards, so that water can ﬂ ow out.

• Make sure the smaller crockery do not fall from the rack.

• Check all the wash arms runs freely and they are not blocked by too tall or too prominent crockery. Eventually, run a manual rotation of the arms to check it.

Some foods, such as carrots, tomatoes, and others, may contain some natural dyes substances, that in large amounts, can alter the crockery and plastic parts colors. Any discoloration does not mean that the plastic is not heat resistant.

Crockery and cutlery not suitable for dishwasher

Not suitable for dishwasher:

• Wooden crockery and cutlery or with wooden parts; water at high temperature causes deformation to wood. Also the adhesives used are not suitable for treatment in the dishwasher; a consequence could be the handles detachment.

• Crafts, precious vases or decorated glasses.

• Not heat-resistant plastic crockery.

• Copper, brass, pewter or aluminum objects: they may become discolored or opaque.

4. ECOLOGICAL ASPECTS

4.1 Recommendations for optimal use of energy, water and additives

Salt dosing: A pre-set (by the manufacturer) quantity of salt is injected in the resins at each regeneration cycle. It

is important to observe the number of regeneration cycles recommended in paragraph 3.6 Regeneration device

in order to avoid salt spills or lime deposits.

Use the machine fully loaded when possible: This shall prevent detergent, rinse aid, water and energy consumption waste.

Detergent and rinse-aids: Use detergents and rinse-aid chemicals with high biodegradability, to best respect the environment. Verify proper dosage in relation to water hardness at least three times a year. Excess product pollutes rivers and seas while an insuﬃ cient dose results in unsatisfactory dish washing and/or hygiene.

Boiler and Wash-Tank temperatures: The boiler and tank temperatures are set by the manufacturer in order to obtain the best washing results with detergents on the market. The temperatures can be reset by the installer in relation to your detergent.

Pre-washing: Carefully pre-wash with a moderate amount of water at room temperature to facilitate the removal of animal fats. To remove encrusted materials warm water soaking is recommended.

Note: Wash objects as soon as possible to avoid deposits from drying and compromise eﬀ ective washing. For eﬀ ective washing routine dishwasher cleaning and maintenance is advised (see chap.

Disregarding the points listed above and of any the information contained in this manual can cause energy, water and detergent waste with a subsequent increase in running costs and/or performance reduction.

5. H.A.C.C.P. AND HYGIENE REGULATIONS

• When starting the machine ON, no wash-cycle will be starting until the set boiler and wash-tank temperatures are reached. During operation, the machine will not start the rinse cycle till the set boiler temperature is reached.

• Remove carefully all solids from the objects to be washed, to avoid obstruction of ﬁ lters, nozzles and piping.

• Drain the wash tank and clean the ﬁ lters at least twice a day.

• Check if the detergent and rinse-aid dosage are correct (as recommended by the manufacturer). In the morning, before starting the machine, check that the quantity of chemicals in the canisters is enough for daily supply.

• Keep your working tables clean.

• Extract the rack with clean hands or gloves to avoid ﬁ nger marks.

• Do not dry or polish the washed objects with cloths, brushes or rags that are not sterile.

7.1.1 Handling the product

The machines must be handled strictly as shown in pict. 5 regarding the grip points indicated for lifting with a lift truck.

Latch the machine in a way that secures no vibration or shocks during transportation.

N.B.: Slinging with ropes not recommended.

pict. 5

Double check the firm tightness of all hose-clamps on piping, nuts and bolts, and fasteners, that might come loose with the transport, to prevent water dripping or leakages, or other damages, during the machine's operation.

See chapter 9 ENVIRONMENTAL ASPECTS for disposal of the packing material.

7.1.2 Storage

Storage temperature: min. +4°C - max +50°C - humidity <90%. The stored parts should be checked periodically, to detect any sign of deterioration. Do not put anything on the machine, even if packed in its box.

7.2 Prepare for installation

This is just a guide-line for the machine installation. The installation must be performed by a qualiﬁ ed engineer.

7.2.1 Room features

Install the machine, in a room closed to weather and with a guaranteed temperature-range between 5 and 35°C. The machine is equipped with thermostatic sensors to manage the temperatures. To guarantee a proper functionality these sensor shall not operate at a room temperature below 5°C. For this reason, it is fundamental that before starting the machine reaches the room temperature.

7.2.2 Electrical connection - Characteristics

The electrical connection to network shall be carried out in accordance to the local laws in force. Make sure that the supply voltage is the same as reported on the machine plate and that the network can stand the needed power absorption shown on the same plate.

After unpacking, make sure the appliance has not been damaged due to transportation. If it has been, do notify the seller about this problem. If the damage might question the machine’s safety, do not install the appliance.

A suitable omni-polar one-way switch shall be installed and sized according to the absorption provided, in order to completely guarantee the disconnection from the supply mains, under “category III” overvoltage conditions.

This switch shall be included in the power network solely and exclusively used for this purpose and installed in the immediate vicinity of the machine.

Always turn the machine off via this switch. This is the only model of switch that guarantees a total electrical power disconnection.

Make sure that the facility is equipped with efficient ground connection.

WARNING: check very carefully if the “ground connection” of the machine, is properly sized and fully eﬃ cient,

and that not too many units are connected on it. An undersized or poor “ground connection” might lead to corrosion and/or pitting eﬀ ect on the stainless steel plates, even to perforation.

7.3.2 Electrical connection

The electrical connection shall be carried out in accordance to the local laws in force.

The machine has a connection at the back, indicated by the symbol , that is meant to link the steel structure and masses among diﬀ erent apparatuses, to prevent electro-static electrical shocks.

The electrical supply cable must be new, ﬂ exible, and according to "har" H07RN-F or a local valid equivalent. The cable size is dimensioned according to the power.

If the machine is ﬁ tted with a three-phase pump, check the correct motor rotation (right rotation as per arrow on the casing). This is not needed if the pump is a single-phase model (standard).

(see pict. 6). Install suction hoods to assure proper ventilation of the room, in order to eliminate steam and excessive humidity.

Check that the machine is properly levelled, by adjusting the legs. Make sure the machine is not standing on the power cable or on the ﬁ lling/drain hoses.

Level the machine ﬂ at, by adjusting the support feet (see pict. 7).

7.3.3 Water connection

Connect the machine draining hose to the connection located at the bottom, laterally. The drain tube shall always be connected to a siphon in order to prevent the release of odors. Maximum drain height = cm. 50 (see pict. 8). In those machines equipped with “water softener” the water supply temperature shall not

exceed 40°C, to avoid damages to the ﬁ lters’ resins.
