Before connecting the ice equipment with the electric line, check the ampère
again of the unit, detail in the plate, with the correspondent ampère of the
electric supply.
¾ WATER AND DRAIN CONNEXION
- General
When choosing the water line for the modular crush and supercrush ice
equipment of model MF take care of the following: la serie MF,
a) Length of the line
b) Clear and pure water
c) Suitable pressure of the line.
¾ LOCATION AND LEVELLING Water is the most simple and important ingredient for making ice, for this
resason the previous points are very important. A low pressure of water,
below 1 bar can origin problem with the operation of the unit.
Water that contains and excess of minerals can produce a residuum sheet
in the inner parts of the water system, meanwhile a soft water containing
lower mineral salts produce a granular ice too “dry”.
ATTENTION: this ice equipment has been designed to be installed in
areas where the room temperature do no exceed the maximum of 40 º C
nor the minimum of 10 º C
Prolonged period of operation with temperature different ot the
mentioned represents a wrong use of the equipment and suppose the
nullity of the guarantee.
¾ ELECTRICAL CONNEXIONS
To choose the kind and section of the cable observe the ampère indicated in
the plate of the equipment.
All the equipments has an electric supply cable, so it is needed a conection
to the electric line equipped with earth cable and with magnetothermic
switch with fuse appropriate as it is indicated in the plate of each equipment.
The maximum ampere variation permitted does not have to exceed a 10%
of the plate or be less than a 10% of the same.
A lower ampère can produce an anomalous operation and make damage
seriously the protection device and the electric winding.
NOTE: All the external connexions has to be perfect, according with the local
laws. In some cases it is needed the intervention of a qualified electrician..
A
TTENTION: Using soft water (lower mineral salt) with less electric
conductivity of 30 mS don’t let the low tension electricity to go
through between the sensors of water level, causing the stop or wrong
function of the unit.
Chlorine water or ironish water can be partially improve with active coal
filters.
- Inlet of water
Connect the male connector to the water inlet of 3/4" Gas to the water line
using a reinforced plastic pipe with non-polsonous material for food or a
copper pie with external diameter of 3/8".
The inlet water line has to have a stopcock located in an accessible place
near the unit. If water has a high level of impirites it is recommended to install
a fitler or a purifier to prepare it appropriately.
- Water inlet – Water cooling models
The models cooled with water need two separate inlet lines; one for the tank
and the other one has to go through one adjustment mechanic valve to the
cooling condenser.
Also for the water connection of the condenser use a reinforced plastic
flexible pipe or a copper pipe of 3/ 8 with female connector of+" Gas and a
separet bypass valve.

¾CHECKING THE PERFORMANCE WITH THE UNIT WORKING
D. Take out the front panel and if it is needed put the high and low pressure
gauge in their corresponding tyre valve to check the condensation and air
intake pressure.
- Drain
It is recommended a rigid plastic pipe with internal diameter of 18 mm and
constant flow of 3 cm per meter. The draining of remainder water it is made
by gravity; it is necessary a drianing with vertical air inlet near the connector
and that it go to the open siphon for a constant flow.
- Drain – Model cooled with water
The equipment cooled with water need a new line of drain separet with a
male connector 3/4" Gas that comes with the indication “Drain- Only for
cooled with water".
C. After the compressor work 2 or 3 minutes, check that the ice go out
through the unloading hole and through the pipe go to the store.
NOTE: All the water connections has to be perfect and realise according to
the local laws. In some cases it is necessary the intervention of a qualified
plumber.
¾ STARTING
A
fter a correct electrical, water and drain installation, follow the next
instructions for the starting up:
A. Open the tap and connect the plug or electric general switch located in the
electrical connexion line. The first GREEN LIGHT will light, showing the unit
is under tension.
OPERATION INSTRUCTIONS
NOTE: When the unit has been some time disconnected, the RED LIGHT
it is flashing during 3 minutes; afther these minutes it will start the motor ot
the gear reduction and after 5 seconds the compresor.
B. After the 3 minutes, the unit will start up activating the
following components:
- MOTOR / S REDUCTION GEAR COMPRESSOR
- MOTOR / S OF FAN(if the unit is cooling with air), controled by the
temperature sensor of the condenser located in the wings of the same.
NOTE. The first ice granule present a scarce consistence because the
temperature of evaporation still have to reach the normal functioning
value. Wait 10 minutes so as the evaporation temperature go down to
the normal functioning values so as the ice has the correct consistence.
NOTE. If after 10 minutes of being working the equipment the
temperature of the evaporator has not reach below 1°C due to an
inadequate quantity of cooler, the temperature sensor of the evaporator
detects this abnormal situation and consequently stop the unit. In this
circumstance, the YELLOW LIGHT switch on.
After diagnosing and eliminating the problem of this poor
evaporation temperature due to inadequate quantity of
cooler or excessive condensation temperature, press the
boton RESET located in the lid of the control
After 3 minutes, with the RED LIGHT flashing, the unit will start working.

F. Check the correct function of ice level control electronic eyes, put the
hand between the two sensor located in the outlet pipe. (one in every
pipe in model MF61). In this way it is interrumped the beam and switch
off the RED LIGHT located in the front side of the electroic
Card. After 6 second the unit stops automatically and switch
On the YELLOW LIGHT showing the situation FULL CABIN.
The beam of light is retablished after 6 seconds, the unit will start up
Automatically (after de 3 minutes of delay) and the yellow
Light that has been switched on before.
NOTE: in the air cooled models, the condensation pressure remain
between two values preestablished throught the fan, sending
intermittently through the sensor located in the wings’ condenser.
If the condensation temperature reach to 70 º C due to
and obstruction in the condenser and/or the motor of the
fan do not work, the sensor temperature of the condenser
stop the unit and consequently a RED LIGHT of danger is
switch on.
After diagnosing and solving the problem, repit the operation indicated in
the previous “Note” to start up again the unit.
E. Check the correct functioning of the water level sensor, close the
stopcock. After some minutes when the level of water
Go down the sensor, the unit will stop and inmediately
switch on the YELLOW LIGHT showing the lack of water.
NOTE: The water level sensor detects the presence of inadequate quantity
of water in the tank and it confirms it to the microprocessor manintining an
electric low ampère flow through the sensors using the water as a
conductive material.
ATTENTION. To use demineralize water (water whitout or with little
salt) with a electric conductivity of less than 30 mS not allow the
lower tension electricity to pass making the unit to stop or not
functioning, a YELLOW LIGHT swith one showing a lack of water.
After open again the stopcock, the YELLOW LIGHT switch off automatically
and a RED LIGHT is flashing. After 3 minutes the unit start up again, first
the reduction gear and after 5 seconds the compresor.
NOTE. The control level of the ice (infrared system) is independent of the
temperature, otherwise it can be affected for the external light and the dirty or
lime deposits located directly in the eyes(infrared sensors).
For a correct operation of the unit it necessary to install it far away of direct
point of light and to scrupulously observe the points mentioned in the
maintenance of the eyesde los ojos.

¾ WATER CIRCUIT
Water enter into the machine by the inlet line, where there is a small arille filer
located in the back side and here reach the wáter tank going through a float
valve.
PRINCIPLE OF OPERATION
NOTE: The presence of water in the tank is detected by a system of two
sensors that work together with the electronic board. Both sensors use the
water as a conductive to maintain a electric flow of low voltage that it is send
to the electronic board showing the presence of water in the tank. The lack of
water or the presence of soft water with an electrical conductivity with less of
30mS (demineralize waters)means the interruption of electrical flow to the
electronic boards and consequently the stop of the unit and the switch on of
the YELLOW LIGHT of ” lack of water”.
Tank of wáter is located allied of the evaporator case to a high that allows
through the communicative pipes, maintain constantly a correct level of
wáter inside the evaporator case.
Water enters from the tank through the conexion pipe inside the
evaporator case, where it is unfreeze and it is transformed in ice; this is
constantly mantained in movement by a stainless steel shaft that turn
inside the evaporator case.
The shaft, sumerge in water inside the evaporator turn in antitimetable
direction by the action of a reductive motor, pushing up the sheet of ice
that is formed in the internal cooled walls of the evaportor.
The ice, when it is push up by the shaft becomes more thick and when it
reach the crush it is compacted and cut into pieces, going through the outlet
pipe and falling into the ice keeper.
When the unit start up, it start up the continuous process of ice making,
process that continue until the ice keeper is full until the level sensors located
in the pipe of outlet ice.
When the ice interrumps the infrared beam of light between both electronic
eyes ( one or both in the model MF 61), the unit stops, the YELLOW LIGHT
switch on that shows the situation of full cabin.
7

The liquid circuit lead the
refrigerant from the condenser
to the capillary tube through a
dehydrated filter.
When the refrigerant in liquid state
goes through the capillary tube
lose gradually a part of pressure
and a part of temperature.
Then it reachs and enter in the coil
evaporator. Water in contact with
the cooled walls of the evaporator
give heat to the refrigerant that
flow inside the coil, making its
evaporation and the consequent
change of liquid state into steam.
The regrigerant in steam state after
going through the accumulator it is
suck in again in the compressor
trhough the aspiration line.
NOTE: The interruption of the beam between the sensors is inmed
i
ately
showed by the switch off of the RED LIGHT located in the electronic board.
Afther the interrumption of the beam of light during 6 seconds, the unit stops
and the YELLOW LIGHT switch on. The 6 seconds of delay protect the unit
of unnecessary stops due to the eventual interruption of the beam of light,
that can be produced for the fall of the ice through the pipe.
When the ice is taken out of the store cabin and the outlet pipe get free, the
beam of light between the two sensors is inmediately reestablished and the
RED LIGHT is switch on in the centre of the board. After 6 seconds the unit
start up again, the YELLOW LIGHT of full cabin switch off and after 2-3
seconds the ice fall again through the pipe.
¾ COOLING CIRCUIT
The refrigerant in gaseous state and high temperature it is pumped from the
compressor, going through the condenser and it is transformed in regrigerant
in liquid state.
The pressure of push of the refrigerant system (high pressure) it is mantained
between the previously establish values (8/9 bar for MF 22 and 17/18 bar for
MF30, MF 41, MF 51 Y MF 61) through the temperature sensor of the
condenser that has the probe located inside the sheet of the condenser, in th
e
air cooled models.
This sensor notice the increase of temperature in the condenser above the
established limit, change its electric resistance and send low tension electricit
y
to the MICROPROCESSOR of the electronic board that supply through a triac
the fan motor in intermittend way ON – OFF.
8

In water cooled models, the high pressure of the system is constant
to 8.5 bar in model MF 22, and to 17 bar in models MF 30, MF 41, MF
51 Y MF 61, due to a quantity of water that goes through the
condenser, which flow is controled by the action of the presostate
valve that it is open to increase the water flow that cool the
condenser.
9

NOTE, In case the temperature sensor of the condenser detects 70ac ' in the
cooled air model or 62º Cin the water cooled version for one of these
reasons:
- DIRTLY CONDENSER (cooled by air)
- INADEQUATE CONDENSATION WATER (cooled by water)
- BURNT FAN OR STOPPED (cooled by air)
- HIGH ROOM TEMPERATURE (UP TO 43° C)
the unit stop inmediately so as to prevent to be working in extremely
abnormal and dangerous situation. When this happens it switch on the RED
LIGHT,that warn of high temperature.
After eliminating the cause of excessive temperature in the condenser,
push button RE-SET.
The RED LIGHT will flash and after 3 minutes the unit will start working. The
temperature sensor of the condenser has also another option for security, it
consist in preventing the start up of the unit if the room temperature (detected
by the sensor of the condenser) in where it is installed the unit is less than 10
C.
When the room temperature is up to 10º C, the electronic board start up
again the unit automatically after 3 minutes.
The pressure of air intake or low pressure in normal conditions is of 0.5 bar in
model MF 22 and 2.4+2.6 bar in model MF 31, MF 41, MF 51 Y MF 61 after
some minutes of operation. These valuer can change between 0.1 bar or 1.2
bar, in relation with the water temperature that supply the evaporator.
NOT
E
If after 10 minutes of operation not produce ice and the tempertaure
registered by the sensors of the evaporator do not reach -1 C, the unit stops
and switch on flashing the 5th YELLOW LIGHT

¾ DESCRIPTION OF COMPONENTS
A. TEMPERATURE SENSOR OF THE EVAPORATOR
The sensor of temperature of the evaporator, located inside a bulb pipe, it is
welded in the outlet of the freezer tube, register the temperature of the
refrigerant aspirated transmitting a signal (low tension electricity) to the
microprocessor.
Depending on the signal received, the microprocessor give green light to the
ice equipment to continue working (evaporation temperature below -1°C after
10 minutes working or in case there is a lack partially or totally of refrigerant in
the system, stops the equipment flashing the 5a YELLOW LIGHT
(evaporation temperature above -1°C after 10 minutes of operation).
B. SENSOR OF WATER LEVEL FLOAT TANK
The sensor of water level of the flowt tank it is composed of two stainless
steel sensors vertically anchored to the lid and connected electrically to the
low tension circuitry of the electronic board.
Its lower extreme is sumerged in the water tank and throught a current of flow
that it is transmitted through the mineral salt of the water, mark its presence to
the electronic board.
NOTE. The lack of water or the presence of water whitout mineral salt
(electrical conductivity below 30 mS)means the interruption or reduction of
the electric current transmitted to the electronic board, with the consequent
stop of the unit, show with the switch on of the YELLOW LIGHT.
In the models cooled by air, the probe of the condenser control also the
operation of the fan motor through a MICROPROCESSOR of the electronic
board. Using the TRIAC, tjos start up the motor of the fan removing the heat
of the condenser and consequently lowing the temperature.
If the temperature of the condenser is above 62°C to 70°C depending on the
position of the microswitch number 8, the signal that arrives to the
MICROPROCESSOR make to stop the unit.
C. SENSOR OF TEMPERATURE OF THE CONDENSER
The sensor of temperature of the condenser (located between the wings of
the air condenser or in contact with its coil in the case of water condenser)
registers the temperature of condensation and transmitt the variations
sending a signal to the electronic board.
In case the temperature of sensor of the condenser have a value below +3°C
(room temperature too low), the electronic board don’t start up the unit the
temperature of the probe gets to +10°C.
NOTE. So as the unit start up again, push the button REARM (after solving
the cause that has produce the stop) or unplug and plug again the unit.
D. SPEED SENSOR AND DIRECTION OF MOTOR IN THE REDUCTION
GEAR (Two in models MF 61)
The sensor of speed and the direction of rotation of the motor in the reduction
gear (one for each motor in model MF 61). Register through a magnetic
signal (effect hall) the speed and direction of rotation of the motor. When it is
below 1300 revolutions by minute, the signal transmitted to the
MICROPROCESSOR of the electronic board stop inmediately the unit and it
switch on a YELLOW LIGHT.
The same happens when the motor run in the incorrect direction avoinding
that the ice inside the evaportor make a unic body with the axis.
NOTE. To start up the unit in both cases ( slow don and attempt opposing
rotation) push button rearm (after solving the cause that has produced the
stop) or the switch and the electrical connexion.
11

E. OPTICAL SYSTEM OF ICE LEVEL CONTROL (Two in the models MF
61)
The optical system to control the level of ice (one for each discharge pipe in
model MF 61), installed inside the ice discharge pipe, stop the unit when the
level of ice interrumpt the beam of light(by infrared) transmitted between the
two electronic eyes.
When the beam of light stop, the RED LIGHT in the centre of the electronic
board switch off; the continuos stop of the beam of light during more than 10
seconds stop completly the unit switching on the second YELLOW LIGHT.
The 10 seconds of delay for the stop of the unit prevent that the unit stops by
a chance and undesired interrumption of the beam of light (pieces of ice that
fall for the discharge pipe)
En cuanto se quita el hielo para que el haz de luz pueda volver a pasar entre
los ojos electrónicos, la LUZ ROJA vuelve a encenderse inmediatamente

F. ELECTRONIC BOARD
The electronic board, located in a plastic box fix in the front part of the unit,
consists of two separate printed circuit, one of high voltage and the other one
of low voltage, protected by three fuses, integrated it by a button RE-SET
(REARM). There are also 5 lights indicating the operation of the unit, one
extra RED LIGHT , 8 DIP SWITCH of switching inlet and some connection
terminals with the inlet peripherals (sensors) and outlet peripherals (electric
components). The electronic board is the brain of the system and process
through the microprocessor, the signals received by the sensors to control
the functioning ot all the electric components of the unit (compresor,
reduction gear, etc).
The five LIGHTS in the front of the electronic board show the following

G. TANK FOR THE FLOAT
The tank has a plastic box with a float with screw of adjustment in the top that
mantains a constant level of water in the tank and with communicating
vessels inside the evaporator.
In the lid there are two sensors to control the level of water that signs to the
electronic board the presence of water in the tank.
J. REDUCTION MOTOR (two in model MF 61)
It has an asynchrounous one-phase motor with a condenser installed in
reduction gear box of gears and pinions, the reduction motor activate through
a transmission connection the axis of elevation of ice located inside the
vertical evaporator.
The rotation of the motor, subjected by two ball bearing of permanent
lubrication, transmit the movement to a fibre gear (to reduce the fluid) of it,
with a pair of gears and pinions subjected by the roller gears located in the
upper and lower extreme of the outlet axis.
The reduction gear is seal, by the presence of thw retainers installed in the
hole of rotor axis and outlet axis and it is lubricated with specific grease
(MOBILPREX IP 44).
K. MOTOR OF THE FAN (Models cooled by air)
The motor of the fan is comanded through the TRIAC of the electronic board, by the
sensor of temperature of the condenser. It works making to flow the air thorugh the
sheets of the condenser. In conditions with a low room temperature, it can
intermittently work to maintain the condensation temperature between the
pressetablished values.
L. PRESOSTATIC VALVE (Model cooled by water)
The presostatic valve mantains a contant value of high pressure in the
cooling circuit changing the water flow in the condenser. When the pressure
increase the presostatic valve interiorily opens to increase the flow of water in
the condenser.
M. COMPRESOR
The hermetic compresor is the heart of the system and it makes the
refrigerant to circulate in the refrigerator. It intakes the refrigerant as a low
pressure and low temperature steam and it transforms it as high pressure
and high temperature steam, sending it to the circuit through the discharge or
high valve.
NOTE. It is very important to place correctly the lid in the tank of the float, so
as to the sensors be submerged and can transmit an electrical signal that
confirms to the electronic board the presence of water in the tank and avoid
inopportune stop of the ice equipment.
H. EVAPORATOR (Two in model MF 61)
The evaporator has a stainless steel vertical pipe in which external side it is
solded the evaporation chamber of the refrigerant and in which in the interior
there is the axis that turns and it is mantained in axis by the action of the top
and lower treads. In the lower part of the evaporator there is a retention ring
that hermetically seals it, while in the top part there is the ice crusher
machine.
I. CRUSHING RING OF ICE (Two in model MF 61)
The crushing ring of ice is on the top side of the evaporator and it has in
models MF 22-30, two cogs to crush the ice; with its inclined shape (the back
cogs to front) compress and force the ice to come out in horizontal direction.
In the other models, the ice crusher equipment has some rectangular holes
through the ones the ice is compressed. In this way, the ice loses the excess
of water and fall to the storage in compact and dried grains.
In the crush ice machine there is a top tread, and it has two stainless steel
rolling crowns located in a way that can support the axial and radial load of
the axis.
NOTE: It is recommended to check every 6 months the state of the lubricant
as well as the upper tread. 13

A. ADJUSTMENT THE WATER LEVEL IN THE EVAPORATOR
2. To drop the level of water make the same as before but putting down the
tank.
PROCESS OF ADJUSTMENT, REMOVAL AND
SUBSTITUTION OF THE COMPONENTS
NOTE: Reas carefully the following instructions before make a substitution or
adjustment process.
The correct level in the
evaporator is 25mm
below the outlet ice
hole (discharge hole).
A lower level of water
can cause a major
rubing of the ice and of
the axis due to a
quickly freese of water.
When the level of water is above or below than the normal level, the
regulation consists in raising and droping the level of water moving up or
down the tank
1 To raise the level of water act as following:
-a)Take out the screw that fix the support of water tank and raise it all
the necessary until it reach the level required.
-b ) Put the screw in the correspondent drill holes and tighten it.
ATTENTION. Before doing this regulation makes sure that the problem
is the level of water (check troubleshooting). Make sure the electric
supply is disconnected and the stopcock of water close so as to
prevent damages.
B. SUBSTITUTION OF THE SENSOR OF TEMPERATURE OF THE
EVAPORATOR
1.Take out the fornatl /upper panel.
2. Take out the isolation of pipes that connect the evaporator with the
storage heater to accede the bulb tub weld in the pipe of the cooling pipe
outlet and take out the inner sensor of temperature.
3. Look for the connection of the evaporator’s sensor in the back side of the
electric box and disengage it making prise with the anchored tab.
4. To install again the sensor of the evaporator follow this process on the
other way round.
C. SUBSTITUTION OF THE SENSOR OF TEMPERATURE OF THE
CONDENSER
1. Take out the frontal / upper panel and in model MF61 take out also the
right side panel.
2. Look for the sensible bulb of the condenser sensor placed between its
wings and in the models cooled by air and take it out. In models cooled by
water take the bulb out after open the plastic bracket (it can be used again)
