Start-up sequence for "automatic" water level control
versions (Fig. 3).
These models have two operating modes:
- "AUTO" operating mode
• Make sure the pointer on selector knob "8" is set to "AUTO".
• Turn selector "2" to "on" (I). The tank will now start to fill with
water until it reaches the required top-up level.
• Using selector "9", select the wash cycle most suitable for
the type of vegetables being washed. N.B.: The length of the
wash cycle varies according to the program selected: program
I (time 50sec) - II (time100 sec) - III (time150 sec) - IIII (time200
sec).
• Press "START" button "4" to activate the water circulating
pump.
• Using knob "7", adjust the circulating water flow according to
the quantity and type of vegetables (heavy or light) being
washed.
The "AUTO" operating mode activates a PLC which controls
the various cycle phases:
- Pause (pump off): to settle soil particles etc. at the bottom of
the tank.
- Partial empty: to discharge any sediment deposits.
- Automatic top-up of water level inside tank.
- Pump start: to resume wash cycle.
The pump automatically stops at the end of the cycle (water
turbulence interrupted).
• Next, position a trolley alongside the vegetable washer ready
to receive the clean vegetables.
• Press button "6" to raise the basket to the unloading position.
This button may be pulse-operated to ensure that all the water is
drained from the vegetables before unloading them onto the
trolley. In the interests of hygiene, always wear non toxic rubber
gloves when handling washed vegetables.
• Finally, lower the basket back into the tank by simultaneously
pressing basket down buttons "1" and "5". This operation
must only be performed by one operator.
• For further wash cycles, simply repeat the sequence outlined
above.
- "Manual" control operating mode
Follow the instructions in section 2.1 about the water level
control and wash time (water turbulence).

EMERGENCY STOP
• The control panels (Figs. 2 and 3) are equipped with a red
emergency stop button (3). When pressed, this button imme-
diately shuts off the appliance which remains in this condition
even after pressure on the button is released. To reset, rotate
the button (deliberate action) in the direction indicated on the
ring nut. Once the emergency stop button has been reset, the
appliance can then be started up following the full start-up
sequence.

TURNING OFF
• Turn selector knob "8" to empty (pointer to right) to drain
any water from the tank. The drain solenoid valve remains

permanently open.
• Disconnect the electrical switch located upstream of the ap-
pliance.
• Remove the filter from the bottom of the tank and make sure
the bottom is free of dirt or soil. If necessary, rinse down the
bottom and sides of the tank using a shower head or a small
quantity of water.

CARE AND MAINTENANCE
Before cleaning or carrying out maintenance work, always
disconnect the appliance from the mains power supply by
deactivating the cutout switch located upstream of the
appliance.
• Each day wash the stainless steel surfaces with lukewarm
soapy water, rinse and dry thoroughly.
• Sanitise the tank and basket using non chlorine-based
products (e.g. ECOLAB's quaternary ammonia salts) and
rinse thoroughly. This operation should be carried out once a
week.
• When the appliance is not in use, do not leave the tank full
of water since this will inhibit normal steel passivation and
therefore make the steel surfaces more susceptible to the
corrosive action of salt.
• Routinely check maximum water level sensor "S" (if
installed, see Fig. 7) and, if necessary, remove any accumu-
lated leaves or debris.
• When cleaning stainless steel, never under any circum-
stances use abrasive materials such as steel wool, iron
brushes or scrapers, since they may leave ferrous particles
on the steel surface, thereby causing it to rust.
If necessary, use stainless steel wool, taking care to rub the
surface following the direction of the satin finish.
• If the appliance is not used for long periods, proceed as
follows:
- disconnect the appliance from the power supply;
- completely empty the tank and dry thoroughly;
- apply a protective film of vaseline oil to all stainless steel
surfaces by wiping vigorously with a cloth;
- air the premises regularly.
• Periodically (at least once a year) the appliance should
undergo a general inspection. For this purpose we
recommend taking out a service contract.
5.
WARNINGS
• Do not direct water jets towards the control panel when
washing the appliance.
• After cleaning the appliance with alkaline detergents, rinse
thoroughly.
• Do not use corrosive substances (e.g. muriatic acid) to
clean the floor underneath the appliance.
