INSTALLATION and POSITIONING

Bring the dishwasher to the installation site, remove the packaging and check the appliance and components for damage; any damage found must be reported to the transporter in writing. The packaging components (plastic bags, expanded polystyrene, nails, etc.) must not be left within reach of children and pets since they are potentially dangerous. All packaging materials used are environment-friendly. They can be kept without constituting any hazard, or may be disposed of at a specialist waste disposal centre. The plastic components suitable for recycling are marked as follows: PE polyethylene: external packaging film, bag containing the instructions, protective bags. PP polypropylene: straps. PS expanded polystyrene: corner guards, top of packaging. Wooden and cardboard components can be disposed of in accordance with the relevant regulations. When the product is decommissioned it must not be dumped in the environment; it must be disposed of in accordance with the relevant regulations. All metal parts are in stainless steel and can be removed. The plastic parts are marked with the symbol identifying the material used.

Positioning

Warning: the indoor system and premises in which equipment for institutions is installed must comply

with the relevant regulations.

The manufacturer declines all liability for direct or indirect injury or damage deriving from failure to comply with these regulations. Before installation, check that there are no objects or materials near the machine which may be damaged by steam or splashes of washing solution, or that such items are suitably protected. Place the dishwasher in the chosen point and remove the protective film. Level the dishwasher (with the aid of a spirit level) on its adjustable feet to ensure that it is stable; all other mounting solutions must be approved by the manufacturer.

3.1 INSTRUCTIONS FOR TECHNICAL STAFF

Plumbing hookup

PLUMBING HOOKUP

The water pipelines and electricity supply cable lead out of the bottom right-hand corner of the appliance. Connect the water intake hose to a connector with ¾” gas threaded fitting, fitting the filter A provided (in models with Acquastop, the filter and ring-nut form a single unit). The connection to the water mains must only be made with new hoses; the use of old or worn hoses is not permitted.

The dynamic water supply pressure must be between 1 and 6 bar (depending on the model); if it is higher, installation of a pressure reducer is necessary. If the pressure is less than 2.5 bar (for models without rinsing pump) it might be necessary to fit an additional pump on the appliance to ensure optimal performance. Contact the After-Sales Service. It is essential to fit a main stop tap on the water intake pipeline; the tap must be accessible after installation of the appliance, so do not install it behind the dishwasher. The stated cycle duration refers to water intake at the temperature stated and recommended in the "TECHNICAL DATA" table. If the dishwasher is supplied with water below this temperature, the cycle duration might increase depending on the intake water temperature. Drainage: The dishwasher is fitted with a drain pump and can operate with drain connections on the floor or wall.

Page 8

The dishwasher

and any additional equipment

must be connected to the electrical system

by authorised,

Warning: make sure that the intake and drain hoses are not bent, constricted or crushed after installation.

When installing the drain hose to a siphon with valve, the maximum height of the drain outlet is reduced to 600 mm.

Electrical connection

skilled staff, in accordance with the relevant regulations; also comply with the technical instructions for the connection. The total rated power is stated on the appliance’s technical data plate. The electrical protection devices fitted for the dishwasher must serve this appliance only. The user must have a master switch and a

differential safety breaker, with rating suitable for the appliance’s characteristics, installed on the electricity supply line in accordance with the relevant regulations. These switches must be installed close

to the dishwasher, be easily accessible after installation, and provide complete disconnection from the electrical mains in overvoltage class III conditions.

Warning!

The dishwasher is always powered up unless the master switch is turned off.

Connect the appliance to the user’s earth system. The terminal for the connection is in the bottom righthand corner of the appliance. The earth wire (PE) is yellow-green in colour, the neutral wire (N) is blue and the live wires (L1, L2, L3) are black, grey and brown. In the event of single-phase connection (230V-1N~), the connection to the electrical mains must be made using a cable with plug compliant with the relevant

regulations. According to the target market, the dishwasher can be equipped with a cable fitted with plug.

THE POWER SUPPLY CABLE, IF FITTED, MUST BE REPLACED BY THE MANUFACTURER OR AN AUTHORISED SERVICE CENTRE IN ACCORDANCE WITH THE TECHNICAL DATA SPECIFIED ON THE WIRING DIAGRAM SUPPLIED WITH THE APPLIANCE, TO PREVENT ALL RISKS.

3.2 FIRST START-UP

First start-up

The electrical protection system must undergo a functional test before the appliance is put into operation. The appliance must be installed and/or inspected by qualified staff, who will start it up for the first time and provide the relevant operating instructions.

Preparing for use (important) The rinse aid dispenser is fitted on all models, the detergent dispenser only on some. If both dispensers are present put the external detergent and rinse aid containers in place and insert the respective intake hoses on the rear of the appliance into them. Red hose: detergent, blue hose: rinse aid

Before inserting the hoses into the containers, fit the weights (needed to ensure that they always draw in liquid from the bottoms of the containers) and the filters onto their ends as shown. If the detergent dispenser is not factory-fitted, it can be retrofitted after ordering the relative kit.

Page 9

IMPORTANT

Whenever the type of detergent or rinse aid is changed, it is ABSOLUTELY ESSENTIAL to flush out the peristaltic pumps by placing

the external intake pipes in water for a few cycles. Always use only products specifically recommended for use in a professional dishwasher. Failure to comply with this recommendation leads to forfeiture of the warranty entitlement on the appliance’s water system. Replacement of the internal tube of the detergent and rinse aid peristaltic pumps is recommended every 12 months or

15.000 wash cycles, by the After-Sales Service.

Using the water softener (on models with this feature only)

The quantity of lime in the water (which indicates its hardness) causes whitish marks on dry dishes and dishes also tend to lose their shine over time. The dishwasher is equipped with an automatic water softener which removes the substances that cause hardness from the water with the aid of regenerating salt.

The first time the dishwasher is used, a litre of water must be poured into the tank with the salt. Whenever the tank is filled, always take care to ensure that the cap is firmly closed. The mixture of water and detergent must not get into the salt tank, as this would impair operation of the regeneration system. In this case warranty cover will be forfeited.

4.2 Modifiable parameters

The illustrations are purely guideline. The minimum and maximum temperatures available depend on the model (glass washer, dishwasher, undercounter or hood-type model, ..).

Rinsing temperature (boiler temperature)

Washing temperature

(tank temperature)

Warning: The tank and boiler temperatures shown on the display may be different from the actual

temperatures by a few degrees, especially in transient phases (just after the FILL is completed, just after the end of the cycle, etc.) due to the inertia of the measurement probe.

Adjusting rinse aid dispensing (optional if installed)

Every time is pressed, the value increases of 0,1 g/l up to a max. of 2 g/l.

Default: 1,2 g/l.

Adjusting detergent dispensing (optional if installed)

From 0,0 g/l to 3,0 g/l every time is pressed, the value increases of 0,2 g/l. Beyond 3,0 g/l every time is pressed, the value increases 1,0 g/l up to 10,0 g/l (maximum value).

Factory-set default value = 2 gr/lt.

"Clean water" cycle

Thermostop

With this option clean water is used for every washing. At

each cycle, the washing water is completely drained and it is

replaced with clean water from rinsing.

On: enabled – OFF: disabled.

N.B.: prolonged use of this option leads to higher detergent

and rinse aid consumption.

Set as “on” = minimum rinsing temperature as set, (see boiler temperature above) regardless of intake water temperature; the cycle duration may be a few seconds longer than the nominal length. Set as “off” = the minimum rinsing temperature might be a few degrees lower than the setting if hot intake water is not used.

If the thermostop device is set “off” the rinsing °t are no longer monitored and the user is

responsible for ensuring that the minimum correct °t are maintained for the tank and boiler. It is particularly important to check the intake water temperature. Also refer to the insufficient washing/drying /foam in tank point of the “troubleshooting” section : restore °t Stop ON and/or connect the appliance to a hot water supply.

High speed (FST) or economy (ECO) filling (FILL)

Fast start (FST): starts the dishwasher in less than the

standard time; leads to higher water consumption for the

first cycle start.

Eco start (ECO): starts the dishwasher in standard time, with

no added water consumption.

On: enabled – OFF: disabled.

4.3 Starting the peristaltic pumps – rapid filling of detergent and rinse aid delivery circuit

Perform after the parameter modification procedure explained in the previous point

With the dishwasher powered up and the tank full, press the on/off button for a few seconds; when ------ appears on the

display, release the button and press it again quickly within

0.5 seconds. The peristaltic pumps continue to operate until the same button is pressed again. The rinse aid and detergent symbol lights flash alternately as long as the pumps are on; bear in mind that the rinse aid peristaltic pump fills the circuit in about 7 minutes, while for the detergent it only takes 2 minutes. So draw only rinse aid from the jerry cans (1 for the rinse aid and the other for the detergent) for the first 5 minutes and then also take in detergent for the last 2.

On some models, the message “door” (PCB self-diagnostics on dishwasher closure) may appear during the setup procedure. To reset the message, open the dishwasher door and close it again. If the message persists, contact the after-sales service.

dynamic supply pressure, cleanliness of the inlet water filter, cleanliness of the rinse nozzles, any damage of the water charging hose. If the problem still occurs during the “FILL”:

- Work level tank pressure switch damaged (it always detects “empty”: check if the tank safety pressure switch starts operating).

- Leakage from the tube connected to the air trap; if the problem is not solved, it occurs during the work program.

- vent valve of the drain pipe obstructed with dirt: with siphonage, the tank gets completely empty at the end of a washing program.

Check:

- filter cleanliness; obstructions, bending and narrowing of the drain pipe.

- possible obstructions of the drain pump (blocked with a foreign body). In case the problem is not solved, please contact the After-Sales Service.

The problem might occur because water is continually entering the tank (the causes are as for “Er 05” – see above) If the boiler heating element is damaged, this might be due to operation with no water in the boiler - the pressure switch is indicating full even with the boiler empty: - damaged boiler heating element – contactor failure - open on boiler safety thermostat side. boiler temperature probe faulty or incorrectly positioned - motherboard relay failure, Important: If the boiler heating element is damaged, this might be due to operation with no water in the boiler, pressure switch continues to give full reading even with boiler empty: check boiler air trap and/or relative pressure switch and replace if necessary.

8 MAINTENANCE AND CLEANING

Although no particular scheduled maintenance is required, users are advised to have the dishwasher checked by a specialist technician twice a year. N.B: the manufacturer accepts no liability for wilful damage or damage deriving from carelessness, neglect, failure to comply with instructions, regulations and standards or incorrect connections, which will lead to forfeiture of warranty cover.

The dishwasher has IPX4 protection, but the use of direct water jets for cleaning is forbidden.

Remove the filters (simply lift them out as shown here), taking care that no large residues fall into the sump underneath. Clean them to remove residues and rinse with plenty of water, then put them correctly back in place; do not use sharp or pointed tools. Clean away any limescale deposits to prevent excessive build-ups;

- If possible, leave the hood or door ajar when not in use;

- Clean surfaces thoroughly and often with a damp cloth; use neutral, non-abrasive detergents which do not use chlorine compounds, which corrode and damage stainless steel.

Do not use the products mentioned above even when cleaning the floor underneath or in the vicinity of the dishwasher,

8.1 Cleaning the filter during the day

In case of particularly heavy-duty working conditions, the filter should be cleaned every 30-40 cycles, keeping the machine in operating conditions; to do this, carry out the “partial tank pump-out” routine (program “P0”)) (TANK UNL).

Press the button, and hold it down, until “TANK UNL” and the duration of 2’ appear on the display.

Confirm by pressing ; light L2 turns blue.

At the end of the pump-out the word “END” flashes on the display. The display returns to showing “P1”. Clean the filter in accordance with the instructions.

After cleaning the filter: for "undercounter" models, press to start filling (FILL).

for hood-type models, filling (FILL) starts automatically when the hood is closed.

Topping up with regenerating salt (for models with softener)

Warning: use specific salt only, do not use cooking sea salt. Salt must be

supplied when the led under the symbol indicated in the left side picture lights up. The salt container has a capacity of about 1 kg of granulated salt.

Correct procedure to refill the regenerating salt:

- start a tank pump-out,

- refill the regenerating salt,

- fill the tank (FILL)

- restart the tank pump-out

- remove any salt residues from the bottom of the tank, as it may cause corrosion/rust. This procedure prevents the washing water to enter the salt container (possible damage to the decalcifier) and that possible residues of salt are left in the tank (risk of corrosion/rust).

8.2 Routine inspection of the spray arms (once a week)

Remove the washing and rinsing (top and bottom) spray arms by unscrewing the central screw; remove the rinsing spray arms 3 and remove the screws 2 as shown. Do not unscrew the nozzles. Clean the holes and nozzles under a jet of clean running water; do not use tools which might cause damage. Reassemble the spray arms with care.

Clean the outside of the appliance with a damp cloth and neutral soap, rinsing and drying thoroughly.

Lengthy periods out of use

If the dishwasher is to be out of use for a fairly long period of time, the detergent and rinse aid dispenser devices must be emptied to prevent crystallisation and damage to the pumps: remove the intake hoses from the detergent and rinse aid

containers and place them in a container of clean water, then perform a few wash cycles followed by a complete pump-out. Finally, turn off the master switch, close the water intake valve and leave the hood ajar until the interior is completely dry. The detergent and rinse aid intake hoses must be put back into the containers when the dishwasher is returned to service, taking care not to swap them over (red hose = detergent, blue hose = rinse aid).
