USEFUL ADVICE
1) MAINTANANCE: Before beginning any cleaning or maintanance
operation, the machine MUST be disconnected from the main power supply.
Frequently check and clean the blades, taking them out from the column to
remove any debris or crustation.
The frequency of this operation is suggested by the quantity of residue or by
non-satisfactory results from washing.
For internal and external cleaning of the machine, do not use corrosive
products such as sodium hypochlorite (bleach) or hydrochloric acid (muriatic
acid), steel wool or steel brushes.
So as not to interfere with the correct functioning of the machine, in the
presence of calcium salts or magnesium in the water you are advised to
periodically de-encrust and keep in good order by using personnel
professionally qualified.
So as to avoid risk of damage from oxidization or corrosion from chemicals,
keep all steel surfaces well clean.
2) FOR BEST RESULTS: An insufficient wash cycle may occur which is
visible when traces of waste remain. Streaking may be caused when the rinse
cycle is insufficient, in which case check that the rinse nozzles are clean and
that the water source is of suitable pressure.
In case of waste remains check that:
-the wash cycle nozzles are clean.
-the wash cycle temperature is at 55°C.
-the detergent is chlorified, of the correct concentration and specifically for
industrial use.
-the suction pump filter is clean
-the dishes are in the correct rack
-the dishes are placed correctly in the rack
3) PROLONGED DISUSE
In case of prolonged disuse, a few weeks, it is advisable to run the machine
empty a few times with clean water so as to avoid the build up of any odors.
If necessary repeat this operation a few times until the the water at the end of
the wash is good and clean.
If the period of disuse is longer, it is advisable to oil stainless steel surfaces
with vaseline and to remove any water from the boiler and the electric pump.
It is always advisable to run the sanitizing and de-encrustation operations
both before and after periods of disuse.

INSTRUCTIONS FOR THE USER
31
4) SANITIZING
It is vital to thoroughly clean the machine at least once a week. It is
advisable to use specifically a detergent which disinfects, the use of which
will substantially increase the following advantages:
-Establishes a secure hygenic state by using active detergents and
disinfectants.
-maintains the machine in perfect hygienic conditions even during periods of
non-use.
At the end of the operation, it is necessary to run the machine empty,so as to
rinse it, for a few minutes.
5) DISENCRUSTATION
In the presence of the use of hard water, lime deposits may formulate
internally and on the dishes, which for hygienic reasons and for good care of
the machine must be removed by disencrustation.
The frequency of such procedure is according to the detergent manufacturers
advice, those products which generally contain a phosphoric acid base.
So as not to damage the machine, do not exceed doses and when the
operation is complete, rinse thoroughly.
6) LOADING AND UNLOADING OF THE MACHINE
For the transportation of the machine from the delivery point to the final
installation position, use a fork lift or adequate lifting equipment used by
authorised staff. Lift the machine by its frame, taking care that any protruding
parts are not damaged (discharges, wiring etc.).
7) MACHINE DISMANTLING
At the end of its normal lifetime, the machine has to be taken apart according
to the local regulations in force by separating the components as follows:
? ?metal parts: hood, platforms, frames, filters
? ?electrical parts: motors, remote control switches, microswitches, wiring
? ?plastic parts: racks, connections
? ?rubber parts: tubes, sleeves
8) RESINS REGENERATION OF THE WATER SOFTENER (only for
machines with built-in water softener)
The flashing of the "C.r. ."(30 sec.) on the display indicates the need to
regenerate the resins. First of all, make sure that in the designated tank
container there is some coarse salt.
This operation has to be carried out with full tank.
Close the hoodand push the "S9" button for approx. 5 sec.
The display show "C. .3." (for 21' and 20"). During this operation the
machine cannot be used.
At the end of the regeneration cycle, first start the self cleaning cycle (see
page 27).

INSTALLATION
During the installation keep the machine leveled in order to ensure proper
functioning (angle of inclication is maximum 2 degrees). To prevent damage
caused by the release of vapors from the accessories, ensure that any adjacent
equipment will not be damaged by these vapors.
After test-running the machine, check that the temperatures used are the
recommended ones at 55°C for washing and 85°C for rinsing.
1) ELECTRICAL CONNECTION:
The electrical safety of this equipment is only assured if it is connected as
follows.
It is necessary to connect the equipment to an effective earthing as specified
by the electrical safety regulations in force. Check that this basic requirement
is complied with, in case of any doubt ask for a careful check of the
installation by a qualified personnel.
In the case the earthing is not efficient there will be a dispersion due to the
suppresser.
The machine shall be included in a correctly dimensioned equipotential,
whose effectiveness is to be very tight in accordance to the procedures set for
in the applicable safety standards. The connection shall be performed through
a screw marked by a plate near the rear side of the appliance.
The manufacturer declines any responsibility for any damages caused by lack
of an effective ground installation. For the electrical power supply have
available a wall circuit breaker switch with multiple phase protection
according the following table with contact aperture distance, equal to or not
exceeding 3mm and a supply cable no less than 2.5mm².
model Supply 380V 3N Supply 220V/3 Supply 220V/1
C1000E 20A 32A 50A
C1300E 20A 32A 63A
For other supplies the cable cross section and the circuit breaker switch must
be calculated according to voltage and length of cabling. If cabling too long
adjust cable size to Amp rating; do not pull on supply cable or install it under
tension. If cable needs to be replaced use type H07RN-F.

INSTRUCTIONS FOR TECHNICAL PERSONNEL
34
2) WATER SUPPLY: Provide a water tap in an accessible location, size
3/4" gas, and that which is connected first to the filter, then to the discharge
tube which are a part of the machine. Pay careful attention to National and
Regional requirements.
The pressure used should not be under 2 bar or over 4 bar (200-400 kPa). If
the pressure is below this requirement, you are advised to install a pressure
increasing pump; if the pressure is over this requirement, use a pressure
reducer.
For best results, it is advisable to have the inlet water with a hardness not
more than 10°French measure.
For a hardness factor higher than this use an ionised switch or invert the
osmosis.
3) DISCHARGE: Provide a discharge at ground level with a syphon and
connection to the machine consisting of a flexible tube, placed in a way that it
inclines towards the final discharge location. Moreover, ensure that the length
is not twisted. Ensure that the discharge tube can withstand temperatures up
to 70°C.
4) LIQUID BRIGHTENER DOSAGE: The dosage from this compartment
is regulated by the regulation screw, of which after being screwed down
completely, should then be unscrewed, three complete rotations.
To fill the dosage tube, turn the machine on without the overflow in place.
Now turn the machine on and off. Repeat this operation a few times at
intervals of a few seconds until the brightener reaches the compartment.
Now wait until the machine reaches the correct temperature.
Then run a few cycles empty and wash normally: if the washed items show
dropspots, it signifies that the brightener level is low; if there is streaking
however, it signifies that there is too much brightener or that the water is too
hard. The variation is according to the type of brightener used.
Now the machine will automatically draw the necessary amount of liquid for
each rinse; when running the wash operations check that the liquid in the
drawer does not run short.
5) DETERGENT DOSAGE (for machines with built-in detergent
dispenser)
With the screw on the side of the detergent pump, close completely the
product intake, then slowly open the screw until the desired intake quantity
has been reached. The correct quantity is indicated by the detergent supplier.
Check that the intake of the pipe during the rinse cycle is as preset. (8cm = 1g
approximately). Maximum intake or delivery distance: 2 meters.
