Check the condition of the packaging, and note any evident damage on the shipping bill. Remove the packaging and check that the appliance is in good condition; immediately report any damage to the reseller and the shipping agent by fax or registered letter with a return receipt. If the damage is such as to compromise the safety of the appliance, do not install or operate it until it has been inspected by a qualified technician.

The packaging (plastic bags, expanded polystyrene, nails, etc. ) are hazardous and must not be left within the reach of children or pets.

Positioning

• Check that there are no objects or materials in the installation area which may be damaged by the steam emitted by the appliance during operation, or if there are, make sure they are properly protected.
• Before positioning the appliance, set up the electrical power supply, water supply and drain connections.
• For flush-mounting single-panel machines, leave a space of at least 10 mm between the machine walls and the adjacent surfaces.
• The floor or build-in unit must be rated to support the weight of the appliance
• To ensure that it is stable, level the appliance with its four feet.
• The appliance is intended for fixed installation only; any other approaches must be agreed with and approved by the manufacturer.
• Remove the protective film from its body panels before operating the dishwasher.

Electrical connection

• The power supply must be fitted with an omnipolar circuit breaker (master power switch) to break all contacts including neutral, with a contact gap of at least 3 mm and thermal cutout or fuses, which must be set or rated to the power indicated on the machine’s nameplate.
• The master power switch must be fitted to the power line in the vicinity of the installation and may be connected to only one machine at a time.
• The mains voltage and frequency must match the nameplate ratings.
• The installation must include a grounding system conforming with established electrical safety legislation, to protect the operator and the appliance itself.
• This appliance conforms to EN/IEC 61000-3-11 certification if the system impedance Zsys is less than or equal to Zmax in the point of interface between the user’s supply system and the public system. The installer or appliance user is responsible for checking that the appliance is connected exclusively to a supply with system impedance Zsys less than or equal to Zmax.
   | Z max
  ---|---
  Utensil washers| 0.21 Ω
  Hood| 0.24 Ω
  Undercounter| 0.41 Ω
• The power cable, which must be exclusively typed H07RN-F with a current capacity at 60°C on the cable:
  • Three-phase machine
  • -5×2.5 mm^2 up to 20 A
  • -5×4 mm^2 up to 30 A
  • -5×6 mm^2 up to 38 A
  • -5×10 mm^2 up to 54 A
  • Single-phase machines
  • -3×1.5 mm^2 up to 16 A
  • -3×2.5 mm^2 up to 25 A
• Must not be stretched or crushed during normal operation or routine maintenance.
• The appliance must also be connected to an equipotential system, connected by a screw marked by the symbol 5021 – IEC 60417.
• The equipotential cable must have a cross-section of 10 mm².
• Respect the polarities indicated in the wiring diagram.
• For further information, refer to the wiring diagram.

Do not use multi-sockets, adapters, cables of an inadequate cross-section or type, or extensions not conform to established electrical installation regulations.

Water circuit hookup
The appliance must be connected to its water supply with a flexible hose. A shut-off valve (cock) must be installed between the water supply line and the appliance’s solenoid valve. The cock must be close to the appliance.

• The water supply, temperature and pressure must be compatible with the ratings shown on the technical data plate on the machine.
• Make sure that the water supply flow rate is no less than 20 l/min
• If the water hardness is greater than 14 °f (8 °dH), we recommend using an internal water softener. If the water hardness is greater than 35 °f (19.5 °dH), install an external water softener upline of the solenoid valve
• For machines without water softener: if the water hardness is greater than 14 °f (8 °dH), install an external water softener upline of the solenoid valve.
• If the water has a very high residual concentration of high-conductivity minerals, we recommend installing a demineralization system.
• Machines intended for use with desalinated water or in any case with high sodium chloride concentration must be ordered specifically, as they require specific construction materials
• Do not supply fully demineralized water to machines with a heat recovery unit with batteries with copper pipes. In this case, request the version with batteries with stainless steel pipes.

Connection to the drain line

• The drain line must consist of a free drain sump with siphon suited to the flow capacity of the drain hose supplied with the appliance. The hose must be able to reach the sump without stretching, restriction, folding, crushing, pressing or forcing in any way.
• The tub drains under gravity, so the drain sump must be lower than the machine’s base.
• if the drain is not lower than the base of the appliance, you can use the version with drain pump (available on request).
• In this case, the drain connection may be no higher than 1 m.
• Always check that the drain works properly and is not blocked.
• Any other solution must be approved by the manufacturer in advance.

Rinse aid and detergent

• The rinse aid and detergent are dispensed by the machine’s integral dispenser (depending on the model).
• The dose is set by the installer in relation to the hardness of the water, and he also calibrates the dispensers themselves.
• Before calibrating them, fill the dispenser supply tubes with their respective product.
• The units are calibrated with the adjuster screws, or directly with the control panel (as applicable).
• The level of fluid in the container must be sufficient for priming; do not allow it to drain completely or top it up with corrosive or impure product.

NEVER use CHLORINE or HYPOCHLORITE-based detergents. We recommend installing an automatic detergent dispenser.

MAINTENANCE

General rules
Before doing any maintenance, completely drain out all water, shut off the power supply, and close the water supply cock.

• Do not use water under pressure – it can damage the electrical equipment.
• Only wash the body paneling when it is cold, using only products specifically designed for steel.
• If there is a risk of ice forming, drain the water from the boiler and wash the pump.

Cleaning
To keep the machine in good working order, it must be maintained regularly as explained below. We recommend periodically running a sanitising treatment with suitable non-corrosive commercial products.

Cleaning the filter unit
Run this procedure at the end of the day or when you see the filters are dirty:

1. Remove and clean the baskets.
2. Empty out the tub as explained in “Machine draining”.
3. Remove and carefully clean all the filters.
4. Do not use abrasive products to clean the tub.
5. Restore all removed parts when finished.

Cleaning the arms
The wash and rinse arms are easily removed in order to clean their nozzles and prevent blockage/encrustations.

Proceed as follows ( Fig.10 ):

• Undo nut R and remove the arms.
• Wash all parts under a jet of running water and clean the nozzles thoroughly, using a toothpick or pointed tool if necessary.
• Clean the arm rotation pins inside the machine and wash and rinse the water drainage area.
• Restore the arms and check that they rotate freely.
