Storage:

• Transport and   storage: -10°C to 55°C with peaks up to 70°C (for no longer than 24 hours)

INSTALLATION

• Proper installation is essential to the good operation of the appliance. Some of the data required for installation of the appliance are given on the nameplate on its RH body panel, and a copy is included on the cover page of this manual.
• The appliance may only be installed by qualified persons authorized to do so.
• For Australia and New Zealand, this machine must be installed under AS/NZS3500.1

Unpacking

• 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. ) is 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 that 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
• 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
• The power line, which must be an H07RN-F unit, must not be stretched or crushed during normal operation or maintenance.
• The appliance must also be connected to an equipotential system with the screw marked with the symbol.
• 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 on the machine’s nameplate.
• If the hardness of the water is greater than 14 F (8 dH), we recommend using an internal water softener (available on request). If the hardness of the water is greater than 35 F (19.5 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.

Connection to the drain line

• The drain line must consist of a free drain sump with a 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 a 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.
