MODELS
This manual describes the installation, operation
and maintenance of dishwasher model: SL-900.
The model reference and its specifications are
shown on the identificacion plate located on the
machine.
These machines have been designed and
manufactured in accordance with the following
European directives for safety: 89/392/EEC and
73/23/EEC.
These appliances comply with the EN55014-1
and EN55104-2 standards for the suppression
and exemption of radio-frequency interferences.
INSTALLATION
For optimum performance and long service life of
the machine, follow the instructions contained in
this manual rigorously.
Water connection
Before proceeding with the installation of the
machine, check and make sure that:
1. The mains water connection is within 1.50m
from the foreseen location of dishwasher.
2. At its end on the machine side, the water
supply connection is equipped with a 3/4" GAS
stopcock for the coupling of the water supply
hose supplied with the machine.
3. The dynamic pressure of the water supplied to
the machine is not less than 2 bar (200kPa)
and not greater than 4 bar (400kPa).
4. Inlet water flowrate is at least 20l/min.
5. In places where the water pressure is higher
than the specified one, it will be necessary to
incorporate a pressure reducer to bring the
service pressure within the limits of 2 to 4 bar
(200 to 400kPa).
6. Where water pressure is less than 2 bar
(200kPa), it is necessary to install a pressure
booster pump.
7. Avoid bottlenecks with hoses when making
this installation..
8. On models with gravity draining, connect the
drain pipe of an O.D. of 30mm to the sewage
system. The distance from the sewage system
to the machine base shall not exceed 120mm.
9. On models "B" fitted with a drain pump, the
distance from the sewage system to the
machine base shall not exceed 1m.
10. In order to ensure complete drainage, it is
essential that the machine is even. To level it,
undo or screw in the levelling feet.
Machine installation with a booster pump
Install a pressure booster pump when supply
water pressure is less than 2 bar (200kPa). You
can place the pressure booster pump anywhere
near the appliance, extending the water pipe and
stopcock to the booster pump. Take care that the
stopcock is still accessible. Connect one side of
the booster pump to the stopcock and the other
side to the water supply pipe to the machine.

Electric installation
Single-phase machine: 230V / 50Hz / 1ph
Before starting to install the machine:
1. Check that the mains voltage coincides with
the data on the specifications plate
2. Install a double-pole (2P) switch breaker with
30mA sensitivity and a 40A (2P) double-pole
thermo-magnetic switch The machine is
supplied with a 2 m cable measuring 3 x 6
mm2 that should be connected directly to the
switch
Three phase machines:
Check that the mains voltage coincides with the
data on the specifications plate These standard
machines are delivered
connections
1. Install a thermo-magnetic switch with 25A
(3P+N/400V) or 35A (3P/230V) The machine
is supplied with a 1.70 m cable measuring 5
x 2.5 mm2 that should be connected directly
to the switch
2. Modifying the connections to 3-phase 230V:
•Disconnect the ground (blue wire) from the
supply cable in the connection terminal strip
•Connect the jumper provided in the terminal
strip according to the electrical diagram
•Change the connections in the reboiler
resistor and the drum resistor with the
jumpers provided, according to the electrical
diagram.
•Change the connections in the terminal box of
the motor
EARTHING is OBLIGATORY. Moreover, the
machine includes an external screw for its
connection to a ground equipotential system.
OPERATION OF THE

YCLE IME ELECTOR
By pushing key (2) repeatedly, you can select any
of two wash cycle times. Light indicators show
the selected cycle:
"c": Short Cycle.
"d": Long Cycle.
Choosing the adequate cycle depends on how
soiled crockery is. The dirtier it is, the longer the
cycle has to be for an intensive, thorough
washing.
Start Cycle (3) Fig. A.
If you press this key, the wash cycle starts and
the associated LED (a) turns on. At the end of the
washing phase, the rinsing process starts
automatically and this is shown by LED (b). Once
rinsing has finished, the machine shifts to the
stand-by condition, with LEDs (a) and (b)
flashing. Flashing stops when the door is opened
or a new cycle starts.
Press the key repeatedly to move from one phase
of the cycle to another. So, if washing is on, press
the key to shift to the rinsing process. During
rinsing, press the key to put the machine stand-
by.
Open the hood and press the key to select the
automatic start mode and the "k" light turns on.
The washing cycle begins when the hood is
closed.
"K" LED: This LED turns on when automatic
start is selected. It is switched off by pressing
the key while the hood is open.
Adjustment of Working Temperatures:
Temperatures are factory-set at:
·55-60ºC for the wash tank
·85-90ºC for the boiler
with 400V/3N T
EMPERATURE
•Setting of wash tank temperature: by means of
the wash tank thermostat.
•Setting of boiler temperature: by means of the
boiler thermostat.
•Reboiler safety thermostat: If the reboiler
overheats, this will trigger the thermostat
connected as indicated in the electrical
diagram, which will interrupt the heating and
continuous entry of the water going into the
reboiler. Push the thermostat reset button or
replace it with a new one to cut off the water
entry.
Troubleshooting:
Only qualified technicians may work on the
connections of the electronic board, after cutting
out power to the machine with the main switch
and the automatic safety circuit-breaker at the
external feeding point to the machine.
On the electronic board, there are several light
indicators which are very useful for monitoring
the machine operation and malfunction. Those
ELECTRONIC
indicators belong to either of two groups: input
LEDs or output LEDs.
Input LEDs: those associated with information
received by the electronic board. Their location
and description are indicated on the silk-
(2) Fig. A. screened board and on Figure B. The following
are amber LEDs:
· 'DOOR' LED: ON, when the door is closed.
· BOILER TEMP' LED: ON, when thermostat
contact makes.
· 'TUB TEMP' LED: ON, when thermostat contact
makes.
· 'PRES.SW' LED: ON, when pressure switch is on,
the tub is full.
Output LEDs: They identify the item that has
been activated by the microprocessor. Their
location and description are indicated on the
silk-screened board and on Figure B. The
following are red LEDs:
· "C.CALD." LED (boiler resistor relay): ON, when
boiler resistor is heating water.
· "C.CUBA" LED (wash tank resistor relay): ON,
when wash tank resistor is heating water.
· "WASH PUMP" LED: ON, when wash pump is
working.
· "BOILER S.V." LED: ON, when rinsing solenoid
valve is active.
· "COLD S.V." LED: ON, when cold water or
