INSTRUCTIONS

Water and drain connection:

The water tubes and the electrical power cable stick out from the back of the machine. Connect the water supply tube to a ¾” threaded gas outlet. Use only new tubes for the connection to the water supply; old or used tubes must not be utilized. The dynamic supply pressure must be between 2 and 4 bar; if the pressure is higher, a pressure reducer must be installed. It is indispensable to install a general faucet on the supply water input tubing; the faucet must be accessible after installation has been completed. Do not install the faucet behind the dishwasher.

The declared cycle durations refer to a 50° hot water supply. Where a cold water supply is used, the duration of the cycle could increase in relation to the input water temperature since the dishwasher is equipped with a constant temperature and pressure rinse system.

Drain:

Every dishwasher comes equipped with a drain connection tube; this is prescribed to be at floor level, with a trap drain.

Caution: make sure that the supply and drain tubes are not bent, restricted or crushed after installation.

4.1 Electrical connection

The dishwasher’s electrical connection and that of eventual supplementary apparatus is to be entrusted to authorized and qualified personnel, with respect to the norms in vigor; observe also the technical regulations for the connections. The total power installed is given upon the apparatus’ technical data label. Other apparatus must not be protected along with the dishwasher. The user must provide for the installation, according to the norms in vigor, of a main electrical power switch and of a differential switch compatible with the machine’s characteristics. These switches must be installed near the dishwasher, be easily accessible after installation and guarantee complete disconnection from the electrical supply in category III overvoltage conditions.

Caution!!! The dishwasher is free of electrical current only when the main switch is off.

‐ Connect the apparatus to the usage equalizer. The

clamp for the connection is located at the lower



back of the machine.

‐ The protection conductor (PE) is yellow-green in color, the neutral conductor (N) is blue and the

phase conductors (L1, L2, L3) are black, gray and brown.

5 FIRST STARTUP

FIRST STARTUP

The electrical protection system must be subjected to a functional test before use. The installation must be performed and/or verified by the authorized reseller who will be responsible for the first startup and the instructions relative to the dishwasher’s operation.

PREPARATION FOR USE

Important:

The rinse-aid metering unit comes equipped in all models while the detergent metering unit comes equipped in only some models. If both metering units are present position the external detergent and rinse-aid containers and insert their respective suction tubes located at the back of the machine. Red tube: detergent Transparent tube: rinse-aid Before inserting the tubes in the containers apply the weight (necessary to keep the tube at the bottom of the container) and the filter as indicated in the diagram.

For adjustments, use the adjustment screws indicated in the diagram. It is recommended that adjustments be performed by personnel from the companies who have supplied the detergent products. If the detergent metering unit did not come pre-installed it can be installed at a later time by ordering the relative KIT.

Alternatively, an external metering unit can be connected by means of an electrical connection with a 2x0.5 mm type H05 RN-F cable. This cable must be inserted through the passage indicated in the TECHNICAL CHARACTERISTICS scheme and connected in accordance with the electrical scheme furnished with the dishwasher. The metering unit must be of 230V/50Hz with a maximum absorbed power of 15W. Connect the detergent metering unit to the dishwasher through the red tube cited above.

10 MAINTENANCE AND CLEANING



Notwithstanding that special, programmed maintenance is not required, we recommend having the dishwasher checked by a specialized technician twice a year. Note: intentional damage or that derived from carelessness, negligence, lack of respect for the regulations, instructions and norms or erred connections are not to be considered the responsibility of the manufacturer.

10.1 Daily cleaning

The dishwasher has an IPX4 protection rating, but the use of direct streams of water for its cleaning is forbidden.

Cleaning of the filter during the day



In case of particularly heavy usage it is recommended to perform a cleaning of the filter every 30-40 wash cycles in order to maintain the machine in operative conditions; Use “partial Tank draining” in order to perform these cleanings.

Remove the filters (it is sufficient to lift them out of their lodgings as shown in the figure), making sure that greasy residues do not fall into the opening underneath the filters. Clean away the residues and rinse the filters abundantly before correctly reinserting them; Do not utilize pointy or sharp objects for cleaning. Be sure to remove eventual hardened calcium deposits in order to avoid their accumulation;

‐ Clean the surfaces well and frequently with a damp rag; use neutral,

non-abrasive detergents which do not contain chlorine-based

substances. Corrosive products can damage stainless steel. In order to avoid drops or vapors damaging the steel surfaces, do not even use the above-indicated products for the cleaning of the flooring beneath or around the dishwasher.

10.2 Periodic checks

Disassemble the sprinklers (lower and upper 2-4) by removing the central screw (4); unscrew the caps at the two far ends of the rinsing sprinklers (7). Clean the holes and the nozzles under a stream of clean water. Do not use utensils which could cause damage. Carefully reassemble the sprinklers.

Clean the outside of the machine with neutral soap and a damp cloth. Rinse and dry with care.

10.3 Prolonged disuse

If the use of the dishwasher is not foreseen for a relatively long period of time it is necessary to drain the detergent and rinse-aid dispenser in order to avoid crystallization and pump damage: Remove the suction

tubes from the detergent and rinse-aid containers and emerge them in a container filled with clean water. Perform a few wash cycles and drain the machine completely.

Finally, turn off the main switch and close the water supply faucet. The detergent and rinse-aid suction tubes will be placed back in the containers when the machine is ready to be put back in use, taking care so as not to invert

the tubes (red tube = detergent; transparent tube = rinse-aid). Do not leave the device on, inactive and in disuse for long periods of time.
