MODELS
This manual describes the installation, operation
and maintenance of the SL-19D and SL-20 D
glasswhashers.
The model reference and its specifications are
shown on the identificacion plate located on the
machine.
These machines have been designed and manu-
factured 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.

ENGLISH
Electric installation
Single-phase machine: 230V / 50Hz / 1ph
Before starting to install the machine:
1.Check whether the voltage of the machine (on
its rating plate) coincides with the mains volta-
ge.
2. Fit a 30 mA two-pole differential switch (2P)
and a 16 A two-pole magnetic switch (2P).
The machine is equipped with a cable of a
cross section of 3x2.5 mm² and 2m in length.
This cable must be connected directly to the
switch.
3. EARTHING is OBLIGATORY. Moreover, the
machine includes an external screw for its
connection to a ground equipotential system.

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 was-
hing.
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 auto-
matically and this is shown by LED (b). Once rin-
sing has finished, the machine shifts to the
stand-by condition, with LEDs (a) and (b) flas-
hing. 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.
Adjustment of Working Temperatures:
Temperatures are factory-set at:
·55-60ºC for the wash tank
·85-90ºC for the boiler
T S :
EMPERATURE ETTING
· Setting of wash tank temperature: by means of
the wash tank thermostat.
· Setting of boiler temperature: by means of the
boiler thermostat.
Troubleshooting:
Only qualified technicians may work on the con-
nections of the electronic board, after cutting out
power to the machine with the main switch and
the automatic safety circuit-breaker at the exter-
nal 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
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-scree-
ned board and on Figure B. The following are
amber LEDs:
· 'DOOR' LED: ON, when the door is closed.
· BOILER TEMP' LED: ON, when thermostat con-
tact 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 follo-
wing 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 rege-
neration solenoid valve is active.
Example: If the Washing Water Pump LED is on
and the pump does not work, this means that the
microprocessor gives the order correctly and the
fault lies in an external item such as the contac-
tor or the pump.

ELECTION OF MODEL
To select the machine model, you have to set the
3 microswitches ( Fig. B- 1) on the electronic
board. For this purpose:
1. Power the machine down.
2. Set the microswitches (Fig B-1) according to
the following table.
3. Power the machine up.
