Installation
CONTROL PANEL
This machine is equipped with peristaltic detergent and rinse aid pumps that are controlled through the PCB
board. For that reason in order to adjust the dosing of each one you have to enter the User’s Menu by following
the below steps, please bear in mind that for each second the corresponding pump captures the following
liquid quantities:
• Detergent pump: 0.83 ml/sec
• Rinse Aid pump: 0.19 ml/sec
By multiplying these quantities with the time duration (seconds) that the pump works, you can calculate the
volume of each liquid that it is used.
NOTE
To navigate in the user menu by pressing the buttons SW3 and SW4.
To increase the amount (+), press Button SW1.
To decrease the amount (-), press Button SW2.
To conrm the value changed, press Button SW5 once.
• Press hold Buttons SW1, SW3 & SW6 at the same time for 3 sec with the hood-door closed. LED L6
ashes and buzzer sounds three times. Message “conf” appears for a few seconds and the User’s Menu is
activated.
• Select dF to adjust detergent quantity during initial lling.
• Select dC to adjust detergent quantity during each washing cycle.
• Select rF to adjust rinse aid quantity during initial lling.
• Select rC to adjust rinse aid quantity during each washing cycle.
• Exit the User’s Menu hold SW 6 for 3 sec. until to hear the buzzer sounds.
PRIME THE CHEMICAL PUMPS
Each pump is priming separately. To do that follow the steps bellow.
DETERGENT PUMP PRIMING:
• Dishwasher on standby (OFF).
• Door closed.

16
Installation
• Hold the buttons SW1, 3, 5 together.
RINSE AID PUMP PRIMING:
• Dishwasher on standby (OFF).
• Door closed.
• Hold the buttons SW1, 3, 4 together.
Caution: Before you perform these adjustments, turn off the power supply. The dozer is adjusted
from the manufacturer’s premises at its maximum value for easy initial priming and must be adjusted
accordingly (depending on water hardness, how dirty the dishes are, and the detergent used).
SCREENERS (SURFACE FILTERS) - OVERFLOW PIPE - SUCTION FILTER - DRAIN
FILTER
To remove the surface lters rst align the rinse and washing arms with the middle lter support and then
lift.
Do not remove the surface screeners and internal lters if the tank is not empty

17
Installation
Operation
DAILY OPERATION
• Check the chemical containers to be sufcient full.
• Reposition the overow pipe and the surface screeners.
• Turn on the dishwasher by pressing button SW6 for 3 sec. The LED L6 will ash and the buzzer will sound.
• Wait the tank to ll up with water and chemical pumps to prime. During priming the indication “FILL” will
keep appear on the two 7 segment screens.
The heating elements start warming only when lling is nished. On the screens LCD1 & LCD2 the
current temperature of each tank is displayed alternately (when LCD 1 shows “bt” then LCD 2 displays
boiler’s temperature, when LCD 1 shows “tt”, then LCD 2 displays tank temperature). In case that the
wash tank’s heating resistance is ON, a dot in the right lower corner of LCD1 is lit, while in case that the
boiler’s heating resistance is ON a dot in the right lower corner of LCD2 is lit. For that reason, symbol
(representing the tank) is shown beneath of LCD1 & symbol (representing the boiler) is shown
beneath of LCD2.
• Wait 20 minutes in order both the tank and booster to be fully heated.
During the rst full warming at the start of the swift the washing cycle does not start until the dishwasher
to be fully warmed.
The full heating process is nished when both booster and tank temperatures are minimum 74°C.

18
Operation
• Load the basket in a proper way and place it inside the machine.
All the residuals on the dishes and glasses must be removed
• Close the door.
• Start a washing cycle by pressing the preferable washing cycle time button.
Program Wash time Rinse time
Short (SW1) 103 sec. 16 sec.
Standard (SW2) 163 sec. 16 sec.
Long (SW3) 223 sec. 16 sec.
If for any reason the door open the washing cycle is stopped and must start all over again.
DETERGENT AND RINSE AID PUMP OPERATION
This machine is equipped with peristaltic pumps for the rinse aid and the detergent lling. The lling inlets for
each one are the two corresponding hoses which should be immersed in the appropriate tanks.
The dosing procedure is performed in two stages. Firstly during the initial lling (when you turn the machine on)
and additional after each washing cycle:
• 1st Stage: During automatic preparation (before the rst wash) the machine receives from the tank soap
for 180 sec and rinse aid for 35 sec. This could be adjusted from the user th¬rough the User Menu *Check
Section “User Menu”.
• 2nd Stage: During every complete washing & rinsing cycle, the machine receives detergent for 13 sec and
rinse aid for 12 sec. This could be adjusted from the user through the User Menu *Check Section “User
Menu”.
• When “END” appears on the 2 7 segment screens the washing cycle has nished and you can remove the
basket.
• Allow the dishes and glasses to dry out of the dishwasher.
The dishwasher is equipped with thermo-protector so the rinsing does not start unless the rinse
temperature to be 165°F / 74°C. In this case washing cycle time may be extended until the nal rinse
temperature to reach 165°F / 74°C.

19
Pay attention on removing the basket after the washing cycle as it may be HOT.
• For best results avoid allowing food residues to dry.
• Remove bulk food residues, olive pips, lemon peels, toothpicks, etc., before placing the dishes in the
basket.
• If washing is delayed we recommend that you soak dishes and/or glasses which have food residues.
If, after washing, there are stains from dirt or water spots, the cause may be one of the following:
• Wrong ratio of detergent to water.
• Rinsing water with very high mineral content.
• Improper quantity of rinse-aid.
• Wrong arrangement of items in the basket.
• Low water pressure during rinsing.
• Low water temperature during washing.
• Clogged or miss-positioned lters.
• Clogged jets.
SHUTTING DOWN AND DRAINING
• Remove the overow pipe.
• Press the draining button SW 4 in order to start draining process.
Attention: Do not remove the surface screeners and internal lters if the tank is not empty.
• When draining cycle is nished the dishwasher turns off automatically.
• The draining process includes also self cleaning so during draining hot water from the booster will be
sprayed inside the tank in order residuals to be removed.
• Draining time can be adjusted (more or less ) by entering the general settings of the machine.
• Remove the surface lters and clean them under running water.
• Remove the suction lter and the draining lter and clean them under running water.
• Reposition the lters and overow pipe.
DO NOT use any metal sponge to scratch the lters or the dishwasher surface.
Operation

20
Maintenance
Proper operation and safe use may be ensured only through the correct use of the appliance, as well as
the compliance with the operation instructions, the corresponding specications and the care and cleaning
indications.
Depending on local water hardness, the nozzles on the upper wash piping and rinse arms should be cleaned.
Caution must be exercised to not damage the nozzles. If rinse nozzles are removed, they must be replaced
with the slot in line with the rinse arm.
ATTENTION MUST BE GIVEN TO THE CORRECT INSTALLATION OF FILTERS, WASH ARMS, AND
TEFLON BUSHINGS! REPLACE BUSHINGS IF WORN.
Clean the appliance with warm water and conventional cleaning aids. Stainless steel parts should never be
cleaned them with “steel wool” wire brush, etc, since even the lightest contacts on the surfaces with steel may
contaminate the stainless steel and cause rust formation. Use brushes made of polymer plastic or natural
bristles or thin brass wire. Always keep brush movements in line with grain in the Stainless Steel so that you
will not affect the appearance. Finally, rinse with clean water and dry thoroughly.
We remind you that corrosion (rust formation) on stainless steel surfaces is not created by itself, but rather
due to the use of improper cleaning products (e.g. whitening or particularly caustic cleaning products based on
chlorine).
Occasionally calcium sediments form on the internal walls of the wash compartment, tubing, and booster
chamber (due to mineral particles in the water), which may affect the correct operation of the appliance and
which requires removal.
