MODELS
This manual describes the installation,
operation and maintenance of the SL-21 D
and SL-21 BD dishwashers.
The model reference and its specifications
are shown on the identificacion plate loca-
ted on the machine.
These machines have been designed and
manufactured in accordance with the follo-
wing European directives
89/392/EEC and 73/23/EEC.
These appliances comply
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 dis-
hwasher.
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 sup-
plied 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, con-
nect 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

ENGLISH
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 leve-
lling 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 boos-
for safety: ter pump anywhere near the appliance,
extending the water pipe and stopcock to
the booster pump. Take care that the stop-
with the cock 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 whether the voltage of the machi-
ne (on its rating plate) coincides with the
mains voltage.
2. Fit a 30 mA two-pole differential switch
(2P) and a 16 A two-pole magnetic
switch (2P).
with a cable of a cross section of
3x2.5mm² 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 equipo-
tential system.

ISPLAY
After powering up the machine with main
switch (1), the selected machine model
appears on the display for 2 seconds,
immediately followed by the tub tempera-
ture if the door is closed (LED (a) on) or the
boiler temperature if the door is open (LED
(b) on). During the cycle, the display shows
the wash tank temperature during the was-
hing phase and the boiler temperature
during the rinsing phase.

YCLE IME ELECTOR
By pushing key (3) repeatedly, you can
select any of three wash cycle times. Light
indicators show the selected cycle:
"d": Short cycle
"e": Medium cycle
"f": Short cycle ending in cold rin-
sing
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.

TART YCLE
If you press this key, the wash cycle starts
and the associated LED (g) turns on. At the
end of the washing phase, the rinsing pro-
cess starts automatically and this is shown
by LED (h). Once rinsing has finished, the
machine shifts to the stand-by condition,
with LEDs (g) and (h) flashing. Flashing
stops when the door is opened or a new
cycle starts.
On models with a drain pump, the machine
performs a draining cycle at the end of the
washing phase priot to rinsing. The asso-
ciated LED (j) will then turn on.
Press the key repeatedly to move from one
phase of the cycle to another. So, if was-
hing is on, press the key to shift to the rin-
sing process. During rinsing, press the key
to put the machine stand-by.

RAIN
This key works only if the machine has a
drain pump.
It has the desired effect only when the door
is open. Once pushed (LED (j) on), the drai-
ning cycle starts. By pushing the key again,
the draining cycle stops.
Upon completion of the draining process,
filling will start again, unless the user has
powered the machine down by turning
main switch off.
Adjustment of Working Temperatures:
(Figure B Electronic Boad Diagram)
Temperatures are factory-set at:
· 55-60ºC for the wash tank
· 85-90ºC for the boiler
