INSTRUCTIONS FOR THE USER

14
M115
First Section - FOR THE USER
OPERATION BEFORE WORKING
BEFORE STARTING THE WORKING OPERATION BE SURE THAT:
- the wall-mounted on/off switch is switched on;
- the water and steam* cocks are open;
- water and steam (*) are present in the system;
- the filters are in their housings
- curtains are correctly positioned;
- the inspection doors are closed;
- the dimensions of the dishes to be washed do not exceed the washing working
dimensions;
- Check that the detergent and rinse aid containers are not empty.
- Switch the machine on . Go to the page dealing with the model selected .
(*) for steam machines only
DETERGENTS
In case the machine is not provided with an automatic dispenser, pour the detergent
directly into the washing tank and uniformly distribute it on the filters in the doses indicated
by the supplier.
N.B.: If you make use of chlorinated sanitizers, it is always advisable to employ an
automatic dispenser with feeler for the measurement of the detergent concentration,
because brownish spots can form on the surfaces due to chlorine reactions when pouring
the detergent directly into the tank.
In any case the product shall be introduced near the pump suction pipe in the tank and at
least 15 cm far from the bottom in order to avoid corrosion.
Choice of the suitable cleansing agent is an essential condition if you want to obtain
extremely good washing results as concerns hygienic results. It is then important to
consider some points. First of all only highly alkaline and chlorine-active antifoam
products, especially made for industrial dish-washing machines, must be used and they
must be produced by well known reliable Firms.
Mean concentration of the cleansing agents in powder must be 1,5÷2,5 g/lt. Mean
concentration of liquid cleansing agents nust be 2÷4 g/lt.
In order to avoid scales and corrosions, put cleansing agent above water level on the
nearest area of the sucking pump filter, in this way it will immediately dilute and will not
deposit on the tank bottom.

15
DESCALING
When hard water is used you can find, inside the machine and also on objects,
calcareous sediments which must be removed both for hygienic and operating reasons
by a descaling operation.
Operating process and frequency of this intervention are suggested by your cleansing
agent supplier who has suitable products, generally containing phosphoric acid.
In order to avoid damage to the machine do not increase the quantities and once
operations end rinse abundantly.
HYGIENE
At last each 30 days it would be useful to do this operation which guarantees the
complete hygienic conditions of the machine. We suggest to contact your cleansing agent
supplier who will give you quantity and name of the most suitable product you can use
and that, generally, is an active chloride powder (100÷200 ppm).
In order to avoid damage to the machine do not increase the quantities and once
operations end, rinse abundantly.

on the front panel .
3) Then press the start button “H”.
The washing will start and the racks will
move. Rinsing is operated automatically in
correspondence with the passing through
of the dishes.
4) At this point the machine is ready to
wash the dishes (see page 18) .
5) If it’s required to stop the washing
operations, press the button ”I” to stop the
washing pump and the rack moving.

17
To switch off completely the machine,
press the switch "P" into position "Off"
and turn the wall switch in position OFF.
If lamp M lights on, that indicates possible
anomalies at the motors.
The red mushroom-shaped emergency
pushbutton "P" has to be used in case of
anomaly. Once the trouble has been
removed, it is possible to restart the
machine only after the pushbutton has
been rotated and released.
The machine is equipped with a valve for
the automatic drain.
At the end of the washing operations:
-press button “I” (STOP),
-check that the switch ‘P’ is in position ON,
-open the machine’s door,
-keep pressed button ‘H’ for 3 seconds until

automatic drain will start,
-the drain will automatically stop after 2
minutes,
-switch off the machine and close the door.
N.B. The door can be closed also after the
starting of the tank drain.

18
WASHING OF DISHES
1) Fisrt of all, remove any food residues
and any oily masses .
2) Knives , forks and spoons should be
previously softened; the same applies to
dishes, should they be washed a long time
after their use .
3) Arrange the dishes as shown in the
figures (page 22) .
4) Push the rack toward the inlet of the
machine. The feeding system will make it
step up automatically . (N.B. Insert the
shelves so that dishes are faced to the inlet
and trays are parallel to the machine).
5) There is a limit switch on the output-
table which can stop the machine.
If the operator can not remove the baskets
from the output-table in time and the
baskets accumulate there, the machine will
stop its conveyor and the rinsing system.
In order to restart the normal working it is
sufficient to remove the baskets from the
output-table.
DURING WASHING OPERATIONS
1) Check that the water temperatures are
in accordance with the specified values .
2) Monitor the levels of the detergent and
the rinse agent liquid in the respective
containers .
3) Remove the filters periodically and
remove any residues therefrom; it is
suggested to buy another spare filter in
order not to have to stop the machine for
an extented period of time .
4) Avoid dipping your naked hands into the
soapy hot water present in the tanks. This
can cause burns and skin irritations.
In this case, immediately rinse them with
plenty of water.
5) When the machine is working, do not
open the inspection doors too quickly.
6) In case the conveyor belt is stopped by
the safety device (limit switch), stop the
machine by means of the red emergency
mushroom pushbutton located near the
operator before removing the obstacle
causing the trouble.
7) Deactivate the equipment in case of
fault or malfunction. For repairs, only
address to a technical assistance center
authorised by the manufacturer and
impose the use of original spare parts.
The non-observance of the above could
compromise the safety of the appliance
and of the operators.
For possible troubles occurring during the
working cycles, see the relevant chapter.
