4.Installation and Accessory Parts
4.1 Positioning the Appliance
Position the appliance in the desired location. The back should rest against the wall behind it, and the sides,
along the adjacent cabinets or wall. The dishwasher is equipped with water supply and drain hoses that can
be positioned on the right or the left to facilitate proper installation.
4.2 Leveling the Appliance
Once the appliance is positioned, adjust the feet (screw them in or out) to level the dishwasher. In any case,
the appliance should not be inclined more than 2°. If the appliance is level,it will help ensure proper
performance.
4.3 Cold Water Connection
Connect the cold water supply hose to a threaded 3/4(gas) connector and make sure that it is fastened tightly
in place (see Fig 1).
If the water pipes are new or have not been used for an extended period of time,let the water run to make sure
that the water is clear and free of impurities.If this precaution is not taken,there is a risk that the water inlet can
get blocked and damage the appliance.
4.4 Drain Hose Connection
Insert the drain hose into a drain pipe with a minimum diameter of 4cm,or let it run into the sink, making sure
to avoid bending or crimping it. Use the special plastic support that comes with the appliance (see Fig.2). The
free end of the hose must be at a height between 40 and 100 cm and must not be immersed in water.

4.5 Electrical Connection
After making sure that the voltage and frequency values for the current in the home correspond to those on
the rating plate (located on the stainless steel inner door of the appliance) and that the electrical system is
correct for the maximum voltage on the rating plate, insert the plug into an electrical socket which is earthed
properly (the earthing of the appliance is a safety requirement mandated by law).
If the electrical socket to which the appliance must be connected is not appropriate for the plug, replace the plug, rather
than using adaptors or the like as they could cause overheating and
burns.
Caution:
The dishwasher plug must be accessible even when the appliance is installed as a built-in unit so that maintenance can
be done safety.

Detergent
Detergent specifically intended for use with dishwashers must be used. The dispenser must be refilled
before the start of each wash cycle following the instructions provided in the "Wash Cycle Table." The
detergent dispenser is located on the inside panel the door.
Loading the detergent
To open the "A" cover on the dispenser, press the "B" button. The detergent for the wash cycle should be
poured into the "C" compartment.
After the detergent has been placed in the dispenser, close the cover and press down until it clicks in
place.

Notice: To facilitate closing the cover, remove any excess
detergent on the edges of the dispenser.
Dishwasher detergents are strongly alkaline. They can be
extremely dangerous if swallowed. Avoid contact with the skin
and eyes and keep children away from the dishwasher when the
door is open. Check that the detergent receptacle is empty after
completion of the wash cycle.
Rinse Aid
This product makes dishes sparkle and helps them to dry without
spotting. The dispenser is located on the inside panel of the door and
should be filled after every 80 wash cycle (or when the rinse aid
indicator light comes on for those models with this feature).
Loading The Rinse Aid
To open the dispenser, turn the "C" cap in the anti-clockwise direction
and then pour in the rinse aid, making sure not to overfill. The amount of
rinse aid used for each cycle can be regulated by turning the "F" dose adjustor, located beneath the "C"
cap, with a screwdriver. here are 6 different settings; the normal dosage setting is 1.
Important
Proper dosage of the rinse aid improves drying.
If drops of water remain on the dishes or spotting occurs, the dosage adjustor should be turned to a higher
setting. If the dishes have white streaks, turn the dosage adjustor to a lower setting.

Before placing the dishes in the dishwasher, remove the large food particle to prevent the filter from becoming clogged,
which results in reduced performance.
If the pots and pans have baked-on food that is extremely hard to remove, we recommend that they be allowed to soak
before they are washed. This will eliminate the need for extra wash cycle.
Pull out the rack to facilitate loading the dishwasher.
How to Use the Lower Rack
We recommend that you place the items which are the most difficult to clean items on the lower rack: pots, lids, serving
dishes and bowls, as shown in the figure to the right.
It is preferable to place serving dishes and lids on the sides of the racks in order to avoid blocking the rotation of the top
spray arm.
- Pots, serving bowls, etc. must always be placed face down.
- Deep pots should be slanted to allow the water to flow out.
- The silverware basket can not be doubled (see fig.A) .
- Silverware should be placed in the silverware basket with the handles at the bottom; if the rack has side baskets, the
spoons should be located individually into the appropriate slots. Especially long utensils should be placed in the horizontal
position at the front of the upper rack.
How to Use the Upper Rack
The upper rack is designed to hold more delicate and lighter dishware, such as glasses, coffee and tea cups and saucers,
as well as plates, small bowls and shallow pans (as long as they are not too dirty).
Position the dishes and cookware so that they do not get moved by the spray of water.
The upper rack can be adjusted for height. (See fig.B)
