MODELS
This manual describes the installation,
operation and maintenance of the SC-
1100/B/BP and SC-1220/B/BP dishwashers.
The model reference and its specifications
are shown on the identificacion plate
located in the machine.
Models "B": equipped with a drain pump
Models "BP": equipped with an Air gap-
Break Tank and rinsing booster pump.
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
and EN55104 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
(440kPa).
4. Inlet water flowrate is at least 20l/min.
5. For good washing results, the hardness
of water (lime) must not exceed 10
hydrotimetric degrees.
6. 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 and
400kPa).
7. If the water pressure is less than 2 bar, it
will be necessary to install a pressure
booster.
8. Avoid bottlenecks with hoses when
making this installation.
9. On models with gravity
connect the drain pipe of an O.D. of
4
ENGLISH
30mm to the sewage system. The
distance from the sewage system to the
machine base shall not exceed 280mm.
10. On models "B" equipped with a drain
pump, the distance from the sewage
system to the machine base shall not be
greater than 1m.
11. In order to ensure complete drainage, it
is essential that the machine is even. To
level it, undo or screw in the levelling
feet.
12. Models "BP": The inlet solenoid valve
includes a flowrate controller different
from the standard model, as stated on
the spare parts list. This model is
capable of operating at an input water
pressure ranging from 0.7 to 5 bar and
a minimum supply of 7l/min.
Machine installation with a water softener
If the lime content of the water is higher
than 10 degrees of hardness, install a
SAMMIC water softener. The installation
instructions of this device come with it.
Avoid bottlenecks before and after this
installation as flow would be reduced
producing loss of pressure.
Machine installation with a booster pump
Where the inlet water pressure is lower than
2 bar (200kPa), install a booster pump.
The booster pump may be installed
anywhere near the machine, approaching
the water piping and corresponding 3/4"
cock to the device. Ensure that the water
cock is still accessible.
Connect one end of the booster pump to
the water cock and the other end to the
hose supplied with the machine.
Electric installation
Single-phase machine: SC-1100
Check whether the voltage of the machine
coincides with the mains voltage.
1. Install a 40A (1P+N) switch of the
magnetothermal type. The machine is
equipped with a cable of a cross section
of 5x4mm² and 1.70m in length. This
cable must be connected directly to the
switch.
Three-phase machines: SC-1100/SC-1200
1. Check whether the voltage of the
machine coincides with the mains
voltage. Series-production machines are
delivered, prepared with a 400V/3N
drainage, connection.
2. Install a 25A (3P+N/400V) or 35A
(3P/230V) magnetothermal switch. The
machine is equipped with a cable of a
cross section of 5x4mm² and 1.70m in
length. This cable must be connected
directly to the switch.
3. If the motor rotates in the opposite
direction (producing abnormal noise on
model SC1200), it is necessary to invert
two phases of the power supply.
4. Changing connections for a 230V/3-
phase supply:
· Disconnect the neutral (blue wire) of the
power cable from the connecting strip.
· Connect the bridge to the connecting
strip as shown on the wiring diagram.
· Change the connections at the heating
resistor of the boiler and at the heating
resistor of the tank, placing the bridges
included in the supply as shown on the
wiring diagram.
· Change the connections in the motor
terminal box.
· EARTHING is OBLIGATORY. Moreover,
the machine includes an external screw
for its connection to
equipotential system.
OPERATION
Starting
1. Open the 3/4" stopcock to allow water to
enter the machine.
2. Turn on the switch. Turn on the booster
pump if one has been incorporated to the
machine.
3. Check that the filter of the motor-driven
pump (M), the upper filters (N) and the
drain plug are in place.
4. Turn the switch control (A) to the ON
position for the automatic filling of the
wash tank and the connection of the
heater elements.
5. The light indicator (C) turns on when the
washing temperature (55/60ºC) has been
reached. Now introduce the detergent
into the tank: 1/2 coffee cup at the
beginning of the first cycle and a same
amount every 10 cycles approximately.
6. After putting the rack full of dishware
into the machine, close the lid. A washing
cycle starts automatically and the cycle
light indicator (B) turns on. This indicator
turns off on completion of the cycle. If
the lid has been lifted for any reason
whatsoever and you do not want the
cycle to start when lowering the lid, just
disconnect the main switch before
lowering the lid and turn the machine on
a ground
