Connect the water supply to the machine using a stop valve that is capable of shutting-off the flow of water quickly and
completely.
Make sure the pressure of the mains water is between the values written on the table.
If it is lower than 200 kPa (dynamic pressure), to ensure the perfect operation of the machine, it is mandatory to install a
pressure booster pump (on request, the machine can be supplied with a built-in pressure booster pump).
If the mains pressure is higher than 400 kPa, you need to install a pressure reducer.
For water with average water hardness above 12°f, it is mandatory to use a scale inhibitor. On request, the machine can be
supplied with a built-in scale inhibitor.
If the machine is equipped with a scale inhibitor, you need to regularly regenerate the resins using special regeneration salt.
The salt compartment can take approximately 1 kg of grain salt.
The salt compartment is located on the bottom of the tank. Take the basket out, unscrew the cap and pour salt in using the
funnel supplied with the machine. Before screwing the cap back on, remove any spilled salt near the opening. Top-up with salt
when there is no water in the tank so that the washing water cannot get into the water softener. Always unplug the machine from
the mains power supply before doing this operation. Remember to plug the appliance back into the mains socket after finishing
the job.
The first time you use the appliance, after adding the salt, add some water to the salt container.
NB: For water with hardness above 12°f, if there is no scale inhibitor, the damages caused by scale will not be covered by the
warranty.
The temperature of the supply water must be between the values indicated on the table.
Each machine is supplied with a water filling hose with threaded 3/4”fitting.
The drainage hose is to be connected, after adding a siphon, directly to the drains. The water falls freely into the drains,
therefore the point where it is connected to the drain outlet must always be below the level of the wash tank. If the existent drain
point is above this level, a suitable drain pump has to be installed (optional). Do not fit the drain hose into the drains of sinks,
bathtubs etc.
For versions with built-in osmosis system, install the carbon or mesh filter supplied on the water supply cock. The water
hardness must be between 7 and 12°F and the maximum temperature 30°C.
The filters must be replaced at least twice a year.
Failed observance of these parameters will cause the internal osmotic membrane to deteriorate rapidly.
Make sure the water hardness is between 7 and 12°F, otherwise install a water softener to prevent damages caused by
scale, which are not covered by warranty.
1° FRENCH = 0.56° German = 0.7° British = 10 p.p.m.
2.4 ELECTRICAL CONNECTION
The electrical connection must be carried out according to technical standards currently in force.
Make sure the measured mains voltage matches that written on the technical data nameplate of the dishwasher.
You have to fit an appropriate omnipolar protection circuit breaker switch suitable for the input of the dishwasher.
This switch must be used exclusively for this utility and installed right next to it.
Make sure the electrical systems are suitably earthed.
The machine also has a connection, at the rear bottom part, marked with the equipotential symbol that is used to connect
various appliances together equipotentially (check standards on electrical systems).
FOR MACHINES WITH THREE-PHASE POWER SUPPLY, BE CAREFUL NOT TO INVERT THE PHASE WIRES WITH THE
NEUTRAL WIRE.
ATTENTION ! MAKE SURE THE THREE-PHASE PUMPS TURN IN THE CORRECT DIRECTION (where installed).
