6. INSTRUCTIONS FOR INSTALLERS
6.1 PREPARING FOR INSTALLATION
Carry out the following operations:
- place the appliance in the desired position on a solid, flat and stable floor; - take care not to damage the appliance by banging it against nearby objects during loading and
offloading operations; - Only qualified personnel, equipped with safety measures, can be present in the area during installation; - Remove the appliance from its packaging, taking care not to damage any protruding parts (drains,
wiring, power cable); - remove the protective film; - Check that the appliance is in good condition. In the event of visible damage to the appliance contact
the retailer and the courier responsible for delivering the product immediately. If in doubt do not use the appliance until it is checked by a specialised technician; - transport and move the appliance using a fork-lift by inserting the forks under the appliance. - carefully level the appliance by using the levelling feet; - clean the appliance before using it with a cloth dampened in water and bicarbonate or other neutral detergents and dry carefully.
6.2 WARNINGS
- Prior to connecting the machine to the power and water supply read the general instructions and the information indicated on the data plate by the manufacturer.
- Do not leave the machine in rooms with a temperature lower than 0° C; - The degree of protection of the machine is IP X4. Therefore it should not be washed with direct high-
pressure water jets; - In the event of damage or breakdown switch off the appliance immediately. - Only use original spare parts to replace damaged ones..
6.3 LAWS, TECHNICAL REGULATIONS AND GENERAL RULES
Comply with the following during installation: a) safety norms; b) laws in force in the country where the appliance is installed; c) read all the indications given in this handbook carefully as they provide important information for safe installation, use and maintenance; d) keep this handbook in a safe place for future reference by those who use the appliance;
6.4 INSTALLATION
Installation, start-up and maintenance of the appliance should only be carried out by specialised personnel in compliance with the instructions provided by the manufacturer. The manufacturer declines all responsibility if the appliance malfunctions due to incorrect installation, tampering, improper use, poor maintenance, failure to comply with the local laws and inexperience in using the appliance.
7. CONNECTING THE WATER SUPPLY
Prior to connecting the appliance to the water supply make sure that a gate valve or tap has been placed between the water supply system and the appliance that allow the power supply to be interrupted if needed or if repairs are required. The water supply minimum pressure, measured when water enters the machine during the final rinse (flux pressure), should not be lower than 2 bar, even in the presence of other open taps on the same line. We recommend that each machine is equipped with its own pipe having reduced length and a sufficiently large cross section so as to avoid pressure or load losses. An additional rinsing pump, available as an optional item, must be installed in cases where pressure is lower than the minimum value required. A pressure reducing valve must be installed upstream from the supply pipe in cases where static pressure is greater than 5 bar. The supply pipe of the machine must have a capacity equal or greater than 20 lt/min. A successful final rinse cycle is strictly dependent upon adherence to the values shown. The drain hose must be connected directly to the drain duct after a siphon has been interposed. Drainage occurs by gravity, therefore the joint to the drain hose must always be positioned below the bowl level.
7

If the existing drain is located above the specified level an adequate drainage pump must be installed (optional). Do not install the outlet hose in tubs, sinks etc.

8. CONNECTING THE ELECTRICAL SUPPLY

1) The units are delivered ready for working with the voltage shown on the data plate. 2) Connect to the electricity line, interposing a suitably rated automatic circuit breaker, where the opening
distance between the contacts must be at least 3 mm. Furthermore, supply voltage must not deviate from the voltage value by +5% to -10 %. 3) The characteristics of the flexible cable chosen for connection to the electricity line must not be inferior to the type with rubber insulation H05RN-F and it must have a nominal cross section suitable to absorb maximum current; hence, as indicated in the table, it must have the same minimum cross section indicated relative to the model. 4) To access the power inlet terminal board and replace the power cord, check the positioning in the attached installation diagrams.

N.B. It is essential that the appliance is connected to an efficient earth plug. For this purpose, near the

connection terminal board there is a terminal marked with a plate with the

symbol on it and to

which the earth wire must be connected (yellow-green).

ATTENTION: The use of adaptors, multiple sockets or extension cables is strictly forbidden. Check and tighten all the screws of the electric system which may have become loose during storage or transport.

ATTENTION: Safety device installed; The appliances are equipped with a manual reset safety device which, in the event of an increase in temperature beyond the predefined maximum limit, cuts in, thus interrupting the power supply to the heating elements. The event is signalled by the switching off of the light during normal operation.

9. EQUIPOTENTIAL CONNECTION

If several appliances are installed in a row, the appliance must be connected to an equipotential system whose effectiveness must be verified in accordance with the relative current laws. The connection is at the back of the appliances and marked with the "EQUIPOTENTIAL" plate.

NOTA: the manufacturers decline all responsibility if the accident prevention rules described above are not complied with!

10. ADJUSTMENTS AND CHECKS
The temperature inside the bowl is set at 55/60°C. This temperature favours the correct use of the chemical characteristics of all industrial detergents. It is advisable not to change this parameter. The temperature of the boiler is set at 87-90°C. This value allows the rinse water temperature to be optimized throughout the cycle.
10.1 RINSE AID DISPENSER
The appliance is equipped with a fully automatic rinse aid dispenser. Before starting the appliance make sure that the rinse aid suction tublet is inserted to its container. During the manufacturing process the dispenser is calibrated for maximum opening and must be then adjusted according to the water hardness.
8

Calibration: Turn the adjustment screw anticlockwise to increase the capacity and clockwise to decrease it. A perfect dosage is obtained by turning the adjustment screw by approximately 90 degrees. An excessive dose of surfactant leaves blue streaks on the crockery and leads to the formation of foam in the bowl. On the other hand, if crockery is covered with water droplets and drying is slow it means that the dose of surfactant is insufficient.

Before setting the right amount of surfactant to be used, it is advisable to carry out a specific test to determine the degree of water hardness. If the hardness of the water is greater than 15°F. (French degrees), we advise to install a decalcifyer upstream from the supply solenoid valve of the machine.
Considering that the amount of surfactant varies sensibly according to its concentration and type of formulation, the values listed in this manual are totally indicative and must only serve as guidance. The instructions supplied with the surfactant used will provide useful information on how to determine the necessary dose. In order to determine the exact amount of product, once the suction has been carried out, remove the transparent tublet from the surfactant container and measure the shift in the internal column of liquid. The doses shown have been calculated on the basis of the characteristics of a good product available on the market (with a recommended concentration of 1.5g. per 10lt. of rinse water) and to a water hardness of 1012°F . Given that 1g. of product (1cm³) is equal to 8 cm in the liquid column inside the transparent suction tublet, the indicative amounts for the various models are as follows:

10.2 LOADING THE DETERGENT
Pour the required amount of detergent into the dishwasher by following the instructions provided by the manufacturer. If powder detergent is used make sure that it is evenly distributed in the bowl and does not deposit on one single area in order to avoid the formation of dark stains at the bottom; shake the water. Considering that the dosage varies sensibly (0.8-2.5 grams/litre) according to the product concentration and type of formulation, the amounts shown are purely indicative.

SC40A SC45A SC50A

CAPACITY TUB (l.) 8 18 23

INITIAL DOSE 16 g 36 g 46 g

EVERY 5 WASH CYCLES 7 g 20 g 23 g

Use only specific anti-foam detergents in the appropriate doses.
11. DISPENSER FOR LIQUID DETERGENT (optional)
11.1 START-UP
Before adjusting the detergent dispenser (optional), this and the corresponding small supply pipe must be filled as follows: Supply voltage to the machine. The dispenser is connected in parallel with the load/rinse solenoid valve. DO NOT insert the overflow in the drain hole and run the water until the small transparent plastic pipe and the dispenser are filled. Check the detergent concentration and the supply water hardness by referring to the product data sheet before adjusting the dispenser. Follow the manufacturer's instructions carefully.

The amount of detergent poured into the bowl depends on the amount of water consumed by the machine during each rinse cycle. The amount required may range between 0.8 and 2.5 grams/litre depending on the detergent type and concentration.

11.2 OPERATION

Since the control is parallel to the load/rinse solenoid valve, when the machine is filled with water, the dispenser adds the detergent according to the amount established by the manufacturer. When the rinse cycle starts, the load/rinse solenoid valve allows the dispenser to replenish the detergent in the bowl.

N.B.

The setting of the operation of the dispenser must find a balance between the initial loading and replenishing, by adjusting the operating time in relation to the intervals. One second of dispenser operation corresponds to the input of one gram of product

11.3 HOW TO REGULATE THE DETERGENT DISPENSER

The regulator was designed to allow the dosage of detergent that normally flows through the dispensing pumps. Specifically this regulator carefully balances the two amounts of detergent (the initial and replenish ones) which periodically are loaded into the machine. By fully turning the timer anticlockwise the pump is always off, whereas by turning fully it clockwise the pump is always on. The intermediate settings of interval/operation are exemplified in the diagram below:

11.4 EXAMPLE OF HOW TO SET THE AMOUNT OF DETERGENT REQUIRED
Measure the water consumption of each rinse cycle by referring to the technical sheet of the appliance. For example, let us assume that the consumption is equal to 2 litres: 2 lt of water x 1.5g (hypothetical amount of detergent recommended by the manufacturer for every litre of wash water, taken from the product technical sheet) = 3 (gr. of detergent). Given that 1 gr. = 1 cc. of detergent takes up 8 cm. of the transparent supply tublet of the dispenser, this leads to: 3 (gr. of detergent) x 8 (cm. of tublet) = 24 (cm. of tublet corresponding to the volume of required detergent). The setting must be carried out so that the appliance produces an amount of detergent equal to 24 cm. in length of the supply tublet, for every rinse cycle. By following the same criteria, the consumption of every other dishwasher model can be calculated. N.B. The data provided above refers to a standard supply tublet with a diameter of 5 mm The amount of detergent is right when the crockery is free from any food residues at the end of the wash cycle. An excessive amount of detergent can give rise to the build-up of foam in the bowl and leave white streaks on the crockery. Insert the overflow in its housing and carry out some trial cycles. Perfect wash results can be guaranteed by gradual setting.
N.B. Extra care must be taken in achieving a perfect balance between the amount of rinse aid and the amount of detergent.
Do not immerse your hands in the wash lye. Should this happen rinse immediately with plenty of water. Place the dishes with the cavity facing upwards and the cups and glasses upside down. Place the saucers in the appropriate rack support and the knives and tea spoons in the cutlery basket with the point facing downwards. Do not place silver and stainless steel cutlery in the same container as this may cause silver to burnish and stainless steel to corrode. If possible, wash glasses and glass dishes before the wash cycle. Place the various types of crockery into the appropriate baskets (plates, glasses, mugs and cups, saucers, cutlery etc.).
10

In order to save detergent and energy only start a wash cycle when the dishwasher is full without overloading the racks and avoiding any overlapping of crockery. In order to keep maintenance to a minimum, WE ADVISE TO CLEAN THE CROCKERY BEFORE LOADING THE MACHINE; by removing food, lemon peel, toothpicks, olive pits etc. which could partially obstruct the filter of the solenoid valve, thus compromising the washing performance, the quality of the final result will improve considerably. Remove all food residue from the crockery. Leave the dishes and cutlery with dried-on food residue to soak in water before loading the rack. Place the basket in the dishwasher, shut the door and start the wash cycle. 12 FUNCTIONAL CHECKS Before operating the machine it is appropriate to follow the testing procedure below: 1) CHECKING THE WATER LEVEL:
During the filling of the bowl, the water must stop flowing into the bowl when its level is at least 1 cm below the level of the overflow.
To protect the heating element while the bowl is being drained, the load solenoid valve must start operating again when the water level is 2 cm above the heating element.
2) CHECKING THE RINSE CYCLE: The rinse arms must rotate freely and all the sprayers must work correctly.
3) CHECKING THE WASH CYCLE: The wash water must be distributed with high pressure by all the sprayers. The wash arms must rotate freely under the water pressure.
4) CHECKING THE TEMPERATURE LEVELS: The rinse and wash water temperature levels must correspond to the data highlighted in the "Adjustments and checks" chapter
5) CHECKING THE DISPENSER/DISPENSERS: During each cycle, the dispenser must intake the correct amount of surfactant and/or detergent. To this end, it is useful to remember that 8 cm. of the transparent supply tublet with a cross-section of 5x8 mm. contain approximately 1 gram of product (1 cm³).
6) CHECKING THE WASH RESULTS: The wash results must be visibly satisfactory and the wash cycle must ensure that every possible food residue is removed from the surface of the crockery. The rinse cycle must remove small residues of food and detergent from the crockery. At the end of the cycle, the perfectly clean crockery must dry almost instantly by evaporation as soon as the basket is extracted from the machine.

15. SETTING IN OPERATION:
1. Supply voltage through the main switch upstream from the appliance. 2. Turn the water tap on. 3. Make sure that the filter and the overflow are placed in the correct position. 4. Shut the door and press switch (2); the machine starts filling up with water and detergent. 5. Once the machine has been loaded (from 1 to 4 minutes depending on the type of machine and the
supply pressure) the boiler heating elements automatically come into effect followed by the bowl heating element once the boiler temperature (85°C) has been reached.
If it is necessary to open the door when the machine is running AVOID DOING IT TOO QUICKLY. Although the appliance is equipped with a safety switch to prevent the door from opening suddenly, spurts of water could still reach the user in the event of a hasty manoeuvre. The machine is equipped with a programmer which switches on by briefly pressing the cycle (3) start up button
NORMAL OPERATING CYCLE:
Once the machine is ready to operate as per the "SETTING IN OPERATION" paragraph, follow the instructions below to run the desired wash cycles :
Insert the rack with the soiled crockery and shut the door; Select the long or quick cycle switch (6) press the cycle (3) start-up button. The indicator light (4) will
illuminate when the machine has started the selected wash cycle. In case of accidental door opening the washing cycle will stop and the pilot light (4) will flash at intervals (1 sec.). Once the door will be closed again, the cycle will restart from where it has been interrupted. Once the cycle has finished, the indicator light (4) will switch off. Open the door, extract the rack with the clean crockery and insert another rack, which has been previously loaded, into the dishwasher for the next wash cycle.
N.B. : If the instructions have been followed correctly the crockery will be perfectly clean, dry and hygienically safe. In order to avoid wasting these efforts, make sure that crockery is stored in areas having the same requisites.
16. DECALCIFICATION AND REGENERATION OF RESINS
Some dishwasher models are equipped with a system for water decalcification and the regeneration of ion exchange resins in salt water.
DECALCIFICATION : the system is designed for decalcifying the inlet water that runs through the boiler (without any external intervention).
REGENERATION OF RESINS: a regeneration of ion exchange resins in the water softener is required at regular intervals depending on the hardness of the inlet water (see table) and must be carried out as follows: The machine is set to do the regen program every 50 washing cycles; the warning light (4) will start to blink when the regen program is requested. You can only stop the blinking by starting the regen program.
a) Switch off the machine by pressing switch (2) b) Remove the overflow to drain the bowl (for equipment with drain pump press the button (7) the
draining and regeneration will start on sequence. c) Once the bowl is empty, unscrew the threaded cap (located inside at the bottom of the bowl) and
pour in 1 kg of sodium chloride (large-grained kitchen salt). One load is generally sufficient for ¾ regeneration. d) Shut the door and press button (7) until indicator light (8) remains on. In case of accidental door opening the regenerating cycle will stop and the pilot light (8) will flash at intervals (1 sec.). Once the door will be closed again, the cycle will restart from where it has been interrupted. e) After approximately 20 minutes indicator light (8) switches off signalling that the regeneration cycle has terminated. f) Normal operation can be resumed by following the instructions at paragraph "SETTING IN OPERATION"
N.B. : It is advisable to perform the regeneration process during periods in which the machine is not used. Failure to carry out the regeneration process according to pre-defined intervals will cause the decalcifyer to clog up and the amount of water supplied to the rinse jets to decrease.
13

THE AUTONOMY OF THE DECALCIFYER IS STRICTLY DEPENDENT ON THE CHARACTERISTICS OF THE SUPPLY WATER, FOR EXAMPLE :

Inlet H2o hardness
°F 15 °D 8.4 UK 10.5 °F 25 °D 14 UK 17.5 °F 35 °D 19.6 UK 24.5

1° FRENCH = 0.56° German = 0.7° English = 10 p.p.m.
When the hardness of the water is more than 40°F it is advisable not to use a machine with built-in water softener; it is suitable to install a separate water softener with a capacity not less 12 lt. We also recommend the use of a machine with no integrated purifier and the installation of a separate purifier with capacity equal or greater than 12 1.
17. DRAINAGE PUMP
The exceeding water which enters the bowl at the start of a rinse cycle is automatically drained. Follow the instructions below to drain the bowl completely:
1. Remove the overflow (not the filter) 2. Switch off the machine by pressing the ON-OFF (1) switch 3. Press button 3 to start the draining cycle, the lamp (4) turns on, blinks for 3 seconds and the draining
cycle continue for 2 min. and 20 sec. At this point you can remove the filter tank for cleaning.
In models equipped with an inlet water decalcification system and drainage pump, the water is automatically drained from the bowl during the regeneration cycle.
18. ADVICE TO USERS
18.1 PERIODIC MAINTENANCE
Disconnect the appliance from the power supply before carrying out any cleaning or maintenance operations. Remove the washing impellers every 2-3 days and make sure that there are no food deposits inside. Check the slits and clean thoroughly if necessary. Make sure that the rinse arm can rotate freely. Remove any residues that may obstruct the holes of the nozzles by gently using a thin point. The external surfaces of the machine may be cleaned using non-abrasive products which are specifically designed for stainless steel maintenance. Use a damp cloth avoiding spilling water on the control panel. Do not clean the machine with pressure water jets. Any marks on the appliance interior may be removed using a cloth dampened with water. Do not use corrosive products such as sodium hypochlorite (bleach) or hydrochloric acid (muriatic acid), steel wool or brushes. Any disincrustation of the dishwasher must be carried out only by a specialised technician. High quality products must be used, which are specifically designed by the best manufacturers of industrial cleaning equipment. In case of dirt particles check that:
The washing nozzles are clean; The washing temperature is approximately 60°C; The active chlorine detergent has been measured out correctly and is suitable for industrial cleaning. The pump suction filter is clean; The crockery has been placed in the appropriate rack; The crockery has been arranged well.
14

If the machine is left unused for extended periods, drain the water from the boiler and the electric pump and apply some Vaseline on the stainless steel surfaces.
N.B. : These operations must be carried out only after power has been removed from the appliance by setting the main switch upstream from the machine into the "OFF" position.
