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.

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 output­table 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 int o 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

Don't use detersive, abrasives, steel-wools
or steel-brushes.

14 – In order to avoid the formation of

nasty smells, let the doors open
making sure that they are firmly
linked to the apposite supports.

* for steam machines only

21

Machine prolonged stop

In case the machine is not used for some
weeks it is advisable to carry out an
accurate cleaning of all components inside
to avoid the formation of unpleasant
smells.

In case of a very long standstill, it is
advisable to oil the stainless steel surfaces
with white mineral oil.

HELPFUL SUGGESTIONS

MAINTENANCE

IMPORTANT: Before carrying out cleaning
and maintenance operations disconnect
the machine from the power supply source
by means of the wall-mounted switch or by
means of the disconnecting switch located
on the control panel.

WARNING! - Do not disconnect the switch
when the machine is on!

Check and frequently clean the nozzles.
The frequency at which such operation
shall be carried out will be suggested by
the quantity of residues and scales and by
the unsatisfying washing results.

To clean the machine outside and inside,
never make use of corrosive products such
as sodium hypochlorite (bleach) and
hydrochloric acid (muriatic acid), acids in
general, wire wool and steel brushes.

To avoid compromising the correct
operation and to keep the appliance in
optimal hygienic conditions, it is advisable
to carry out periodical sanifications and
scale removing operations.

ACHIEVEMENTS

Any deficiency in the washing process is
apparent when dirty residuals are visible.
Any halos might be caused by an
insufficuent rinsing: in this case, check that
the rinsing jets are clean and there is a
sufficient pressure in the water distribution
network (2÷4 bar) ;
In the case that residuals are present,
check that:

• the washing jets are clean

• pre-washing temperatur is 40 °C
maximum;

• washing temperature is from 55 to 60 °C,

• rinsing temperature is from 80 to 85 °C,

• there is detergent in the right
concentration;

• the filters are clean;

• washing water is not dirty;

• the positions of the objects in the rack
are correct.

SAFETY DEVICES

The dishwashers are equipped with a
number of devices in order to ensure the
safety of the operator and of the appliance
itself.

LIMIT MICROSWITCH

If dishes reach the end of the unloading
area, before the operator has managed to
unload the basket, the limit switch stops
the drawbar motion and therefore the
baskets.

DOOR MICROSWITCHES

Each inspection door is provided with two
safety microswitches forming two
redundant chains (safety level 2).
If one of the doors is opened accidentally,
the pumps, the conveyor belt gearmotor
and the rinsing area solenoid valve stop
working.

22

This way all washing operations are
stopped preventing dangerous jets of hot
water from spurting out.
Operation is restored only when the door
are closed again and the start button “H”
pressed.

EMERGENCY STOP PUSHBUTTON

The machine is equipped with a red
mushroom-shaped pushbutton on yellow
field, which, if pressed, stops all motors.
Once the trouble has been removed, it is
possible to restart the machine only after
the pushbutton has been rotated and
released. Subsequently press the start
button “H” again.

TORQUE LIMITER

The drawbar forward feeding system is
provided with a mechanical friction torque
limiter located in the drawbar system.
Each time something interposes between
the basket and the machine or the central
drawbar is overloaded, the bar motion
lowers rapidly to zero.
In this case it is necessary to switch the
machine off by means of stop or
emergency pushbuttons, remove the
obstacle and press the start button again.
To calibrate this kind of device, see the
relevant chapter included in the second
part of the manual dedicated to the
installer.

MOTOR PROTECTION DEVICES

Each motor is protected against short­circuits and current overload by automatic
magneto-thermal relays.
Lamp "M" switching on signalizes the
intervention of any of these relays.
In this case, the machine should be
switched off and qualified personnel should
be asked for repair.

ELEMENTS PROTECTION

Each element is protected against short
circuit by automatic breakers.
Tank elements are protected against dry
running by minimum level pressure switch.
Boiler and dryer elements by thermostats
with manual reset.
In case of troubles, ask for the intervention
of qualified and authorized personnel (see
the paragraph dedicated to the user).

RESIDUAL RISKS

Although the appliance is equipped with the
above-mentioned safety devices, danger of
burns to upper limbs persists.

As already mentioned in the paragraph
“DURING WASHING OPERATIONS”,
avoid dipping your naked hands into soapy
hot water of the tanks. This can cause
burns and skin irritations.
In this case, immediately rinse them with
plenty of water.Anyway consult the product
card of the detergent employed.

23

WASHING FLOW CONTROL SYSTEM

pos. “1”

pos. “2”

Highest power (position 1) Lowest power (position 2)

The flow control system is a device that allows You to act on the intensit y of t he washing

power.
This can be useful by washing glasses, when it is necessary to reduce the washing jet
power.

This device is placed into the pre-washing and washing areas of the rack conveyor
dishwashing machines, by the lower washing arms group.

In order to act on the control system You have to rotate the lever “A” by hand anticlockwise
to rise the washing jet power and clockwise to reduce it.

If You turn it thoroughly leftwards, You get the highest power

(pos.1).

If You turn it thoroughly rightwards, You get the lowest power

(pos.2).

USEFUL HINTS OF STAINLESS STEEL MAINTENANCE

Stainless steel is so called because it is not affected by oxidation,this is due to a thin molecular
layer of oxide on the surface which protects againts further oxidation. There are, howevwr,
substances which can modify or destroy this layer,giving rise to corrosion:besides preventing the
protective film of oxide from reforming,these substances corrode the stainless steel itself and can
cause irreparable damage. It is therefore necessary to prevent this by choosing correct cleaning
products and by complying with the following simple recommendations:never forget that when

using these appliances,the first and fundamental rule is to guarantee that the cleaning
products are both non-toxic and hygienic.

Before using any detergent to clean either the stainless steel or the immediate and sorrounding
floor area, always ask your supplier for the most suitable product which does not cause corrosion
on the steel itself; the onset of rust is most commonly caused by the use of unsuitable cleaning
materials (strongly acid chlorate based detergents) or on inadequate maintenance.

Our appliances are made of stainless steel AISI 304 (18-10 type) for exterior panelling,upper
tops,tanks etc.
Comply with the following instructions when cleaning and servicing parts in stainless steel.

Ordinary daily maintenance

Carefully and frequently clean the surfaces using a damp cloth; use soap and water or normal
detergents,so long as these do not contain abrasives or chlorine based substances such as
sodium hypochlorite (bleech),hydrochloric acid or other such solutions:These products quickly and
irreparably corrode stainless steel. When cleaning floors underneath or near the appliances, never
use the above mentioned products as vapours or splashes could subject the steel to similar
destructive effects.
Only ever rub in the direction of the satining, then thoroughly rinse with clean water and carefully
dry.

Rust : water supply pipes, inevitably convey particles of rust dissolved in the water especially in
new installation plants or when taps are opened after a period of inactivity. These iron deposits
must not be allowed to remain on the stainless steel since they produce rust by contamination.
Use suitable products to remove any rust marks,from companies which produce detergents for
industrial use. After application, thoroughly rinse with clean water, neutralizing the action of the
product with an alkaline detergent normally used to clean such appliances or with another specific
product.

DO NOT USE METAL MATS TO CLEAN THE STAINLESS STEEL

authorized to carry out the inspections and the necessary repairs.

The machine should be installed in “Normal” environment, that is to say, indoors, free of
dust, explosion-proof and adequately lit and well aired.

Before installing the machine, it is necessary to arrange the electric and water
connections.
See the reported wiring diagram (supplied by the manufacturer) of the selected model as
far as the dimensions of pipes, cables and wall-mounted switch are concerned.

In order to prevent damages caused by the escape of vapours from the equipment, make
sure that adjacent materials do not deteriorate in their presence.

The Manufacturer cannot assume any responsibility for any damage to persons or
property deriving from the non-observance of the above specified norms.

DETERGENTS

The machine should also be equipped with a detergent and brightener dispenser, which
shall be supplied by the manufacturer of these products.

N.B.: If you use chlorinated sanitizers, it is always advisable to employ an automatic
dispenser provided 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. The feeler

for the measurement of concentration must

be placed on the front side of the tank through the hole “A”

preset for such operation (see

drawing on page 26).
In any case the LIQUID DETERGENT shall be introduced through the preset hole “B”

on

the front side of the washing tank.
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. We provide a short list just as an indication: Ecolab-Soilax; Henkel;
Lever; Diversey; Relativ.

The average concentration of liquid detergents must be 2÷4g/lter. In any case it is
essential that the producer of the detergent rules the dosage properly according to the
features of the installation.

28

As regards the introduction of the liquid rinse aid product, use the passage “C” ,
placed near the water inlet group.
This coupling will allow an appropriate introduction of the liquid rinse aid product.
In order to do this use a fitting with non-return valve.

- rubber components: hoses, sleeves.

29

POSITIONING

During installation, carry out a good levelling
of the machine in order to make it correctly
work (doors, basket forward feeding).
In order to do so use the adjustable feet.

After removing front panels, position the
machine over the connections. Assemble the
inlet and outlet shelves for basket loading and
unloading. The limit switch FC1 is located on
the outlet shelf or on the machine delivery if
the shelf is not provided for. The limit switch
shall be connected to the outlet shelf.

The machine shall also be equipped with
detergent and brightener dispenser, which
shall be supplied by the manufacturer of these
products.

ELECTRICAL CONNECTION
Before connecting the machine,

check to make sure the voltage
outlet of the mains is the same as
the voltage specified on the data
plate of the machine.

It is also necessary to check that the
counter, the mains and the intake are
adequately dimensioned to withstand the
required maximum load.

A main switch must be installed between
the mains and the machine. This safety
measure also requires that the minimum
distance between the switch contacts is at
least 3 mm and the disconnection on all
poles according to EN 60204 (VDE 113).

The mains must be wired to be able to
handle the current drawn by the
machine.The system must also be
provided with a proper ground lead in
accordance with the existings norms. The
electric cable must be of the following
type H07RN-F.

For a correct selection of the cable rated
cross-section refer to the data reported on
the product data plate.
The cable cross-section shall not be
inferior to the one indicated in the
“Technical data and description” reported
in the first page of the present manual.
The cable shall be connected to the
terminal L1-L2-L3 and to the adjacent
yellow-green terminal,on the electric box,
it shall be made passed and stopped by
means of the apposite cable grip.

It is necessary to connect the equipment
to an effective ground installation, as
specified by the electrical safety
regulations in force.
Chack that this basic requirement is
complied with and, in case of doubt, ask
for a careful check of the installation by a
qualified personal.
In addition, the equipment shall be part of
an equipotential system, the effectiveness
of which should be checked according to
the regulations in force.
The connection should be made at the
screw marked by the respective label

located on the equipment lower side (

).
It is recommended to make the electric
line be checked by your own designer.

THE MACHINE SHALL BE
CONNECTED WITH AN EFFECTIVE
GROUND CLAMP.

The manufacturer declines any
responsibility for any damages
caused by lack of an effective
ground installation.

30

WATER CONNECTIONS

Carefully comply with any national or
regional regulations in force.

Hot water supply

Arrange a gate valve in an easily
accessible place, with a tap having a
3/4"gas thread spout at its end and connect
to the water inlet valve (fig.1)

- temperatur between 55° and 60°C,

- Dynamic Pressure 2÷4 bar (200÷400

kPa),

- Hardness between 7,2 and 12,5 °F
N.B.: Each machine is equipped with a

pressure reducer. In order to obtain an
excellent rinsing, it shall be calibrated
according to the data reported on the plate
located in connection with the reducer
itself.

N.B.: Each machine is equipped with a
pressure reducer

near the water inlet
valves.
In order to obtain an optimum rinse it is
necessary to adjust it from 0,6 to 1 bar
according to inlet water pressure and
temperature.

(remember that the required dynamic
pressure must be 2÷4 bar (200÷400kPa)
and that inlet water temperature must be
55÷60°C for standard machines).

If a variation of rinse pressure is required
while installing, proceed as follows:
1: make the machine work and check that
the rinse is activated

;
2: Take away the upper protection plug on
the reduction gear and turn the proper
adjusting screw anti-clockwise in order to
decrease pressure or clockwise in order to
increase it or to restore the optimum
working conditions (see picture 1A).

PIC.1A- PRESSURE REDUCER

Cold water supply

This connection is required only for
machine with steam condenser .
Water shall be supplied at a temperature
ranging from 10÷15°C and at a dynamic
pressure of 2÷4 bar (200÷400 kPa).

31

WATER DRAINING

Reachable from the machine front side
after opening the front panel (to do this
turn the two front screws out);

Arrange a discharge at floor level provided
with siphon and connect to the floor drain by
means of a hose provided with an adequate
inclination. Make sure the drain hose is not
choked in any way.
Make sure the drain hose is resistant to a
temperature of 70 °C.
Carefully comply with any national or regional
regulations in force.

STEAM FEEDING *

As far as steam feeding is concerned,
connect to the machine fittings indicated
in the installation drawings. In order to
make the equipment independent from
the general steam distribution network, it

is necessary to use gate and gas on/off
valves (see draw 2 and 3).

This type of feeding should be supplied at
a pressure ranging from 1 bar (100°C) to
2 bar (121°C).

The steam used should be absolutely
saturated and dry.

STEAM EXHAUST *

The condensed steam exhaust shall have
an appropriate slope toward the recovery
installation or a blow-by pump, in order to
guarantee an autonomous scavenging of
the condensed steam.

N.B.: for possible maintenance operations,
it is advisable to arrange a gate valve
parallel with the discharge so that it is
possible to deviate condensation towards a
runoff pit.

* for steam machines only

32

VAPOURS SUCTION

For machines equipped with splashguard
with collar or normal collar, carry out the
necessary connection as showed in fig. 4.

In any case it is necessary to provide a
way to scavenge steam through a hood
or a similar system.

TESTING

Before starting machine:

During the testing operations, prior to
switching the dishwashing machine on,
check that thermostat of the rinsing boiler
(0°-90° C) is set to zero

and the direction of

rotation of the pumps is correct.
Should the pumps rotate in the reverse

direction, reverse two wires of the line .
Make a number of empty racks to pass

through, then check that water jets are
sprinkled fron the rinsing nozzles then
adjust the thermostat of the boiler to 85° C.

WORKING TEMPERATURES

Check that the thermostats are set
according to the following working
temperatures.

WASHING
The tank thermostat (CT3), also placed
near the wash tank, will be set according
to the following temperature:

Washing water: 55÷60°C.

RINSING
The rinsing thermostat (CT2) will be set
according to the following temperature:

Rinsing water: 80÷85°C.

DO NOT TAMPER WITH THE
THERMOSTAT CALIBRATION

33

TORQUE LIMITER

The limiter has already been described at
paragraph “SAFETY DEVICES”.
It is located in connection with the drawbar
and it is calibrated during testing by the
manufacturer.
In case it is necessary to calibrate it again,
proceed as follows:

1. Switch the machine off ;

2. Remove the protection panel;

3. Load the machine with baskets full of
dishes to be washed;

4. Loose the axial ring nut with the
hexagon ring wrench type “A”;

5. Disengage the friction with a hooked
key type “B” so that it slips;

6. At this point clockwise turn until the
drawbar manages to carry the whole
dishes charge;

7. The device is considered adequately
calibrated when the drawbar hardly
manages to carry the whole charge in
second gear.

34

STEAM CONDENSER

As regards the machines provided with “vapour
condensing” device, pay attention to the
following:

The adjustment of the device is carried out by
means of the regulator valve (COCK “V”)
placed inside the machine base plate and
marked with its special label.

The Manufacturer should rule this cock while
testing the machine.
Never touch this cock without a specific
reason.

This valve rules the water flow in the vapour
condensing battery.

If the machine needed a more precise
adjustment, under regular conditions, adjust
the valve until no more vapour comes out of
the “vapour condensing” cap.

Generally it is sufficient to slightly open the
valve.

ATTENTION! An excessive opening can
cause the cooling of the tank.
