top cabinet lid is made of the same material as the cabinet and provides access for
restocking product containers.
The middle area has the cup dispensing assembly, the cup storage tube assembly, the
stir-stick dispenser and the sugar container.
The cabinet contains the following: the doser, the mill, the brewing assembly, the grain
and soluble product containers, the beaters, the compact, the selector, the recovery
motor, the liquid waste tank, coffee grounds outlet. The following components are
Coffeemar
G-250
// Coffee
MNP116M01GBV00 Date: 09/04/2013 Rev. 1 PAGE 9 OF 95
located at the back of the cabinet: the power assembly, the water inlet solenoid valve,
the air-break, the soluble product distributor, the pressure boiler, the pressure pump and
the volume counter.
Cup dispenser assembly
The cup dispensing assembly consists of a storage unit with 5, tube-shaped columns
that have an internal diameter of 78 mm (3.071”). The columns are joint by flanges
running down their full length, comprising a compact assembly. The assembly has a
pressure fitted star-shaped piece that fits inside the gap left by the five tubes and serves
to mount it on the shaft that supports the cup dispenser .
Fig. 06
The total capacity of the cup storage assembly is 250 cups.
The cup dispenser has a control system that employs
photocells to detect whether cups are present or not. When
the photocell beam is uninterrupted, the 12 V geared motor
inside the dispenser starts and turns the storage assembly to
the next position, controlled by the storage assembly position
microswitch. If there are cups in the column, their own weight
pushes them down until they reach the hole on the dispenser
cover, blocking the light beam from the photocell system. If
every column is empty, the cup storage assembly will rotate
through 8 consecutive positions, to make sure that there are
no cups in any column, in which case it will leave the machine
out of service.
The cup for each serving is delivered by the cup dispenser . It consists of a 12 V geared
motor that simultaneously turns 5 cogwheels. The movement of these cogwheels
releases the cup resting on them at the same time that it restrains the other cups in the
stack (see fig. 07).
Note: The type of cup to be used has to be taken into account.
Furthermore, within each class, the dispensing cogwheels can be adapted to cup
diameter at 0.5 mm (0.020”) intervals. There is a cogwheel displacement system that
allows you to bring them closer to or further away from the cup centre. Follow these
steps to choose the most appropriate system to dispense cups:
1. After deciding on the cup to be used, measure the diameter at the base of the support
ring and determine which category the cup belongs to, 65-67 mm (2.559”–2.638”) or 67-
69 mm (2.638”–2.717”).
Please note that the dispenser cogwheels, the cup collector
supplement and the cup slide will be different in each case.

MNP116M01GBV00 Date: 09/04/2013 Rev. 1 PAGE 10 OF 95
2. Once you have defined the cup in terms of its classification, choose the most
appropriate cogwheel position. To do this, the cup dispenser assembly has 5
intermediate positions for the 2 mm (0.079”) distance between the largest and smallest
diameter at 0.5 mm (0.020”) intervals. Cogwheel position 1 corresponds to the smallest
diameter, while position 5 is for the largest diameter. The other positions are obtained by
adding 0.5 mm (0.020”) intervals. Choose the position immediately above the closest to
cup diameter (see fig. 07)

To change the position of the cup dispenser wheels do as follows:
Remove the cup storage assembly tubes and the star-shaped piece.
1. Lift the cogwheel blocking shaft by holding the end of the shaft that sticks out of the
cup dispenser lid and pulling it until the other end comes out of its recess.
2. Grip the lower cup dispenser bushing and turn it in one or the other direction until the
indicator arrow coincides with the desired position.
3. Release the shaft that will return to its recess thanks to the spring attached to it. To
ensure the shaft is properly anchored, press the shaft down to check that it has gone all
the way into its recess.
Note: Cups can be dispensed manually by pressing the button on the dispenser cover
(see fig. 07).

Stir-stick container
When a cup is dispensed, it falls into a collector that guides it to brewing position. Before
water is dispensed from the boiler to the cup, the sugar and stir-stick have to be first
added.
The stir-sticks are located in a slide with a capacity of
approximately 250 stir-sticks. They are dispensed by a
flap that pulls the stir-stick leaning against the dispenser
at the bottom of the slide. The flap is driven by a 12 V
geared motor. The stir-stick slides through a collector to
the cup.
The stir-sticks should be between 75 and 115 mm
(2.953”-4.528") long and between 1.25 and 1.75 mm
(0.049”–0.069”) wide.
The length of the stir-stick is adjusted to the channel
with the stir-stick length adjuster.

Product containers
The containers are made of food grade polypropylene that is translucent so you readily
see how much product they contain.
Each container is especially designed to hold coffee beans, decaffeinated coffee,
chocolate, milk, tea/soup or sugar, and capacity depends on product type. The
containers are modular pieces.
The sugar and stir-stick dispensers are mounted an assembly located inside the door, on
flanges. This system allows for the complete assembly to turn, to make it easier to load
sugar. The assembly also features an anchoring system to ensure the dispenser’s
position with respect to the cup is maintained. The sugar container is identical to the
soluble containers (short worm) but instead of having an elbow at the outlet, it is
equipped with a rotating door which opens only when the main door that allows the

product to be dispensed into the cup closes. To prevent the sugar from caking on the
container outlet, there is a steam exhaust to remove the steam produced when the end
product is dispensed in the cup. The sugar dosing motor is powered by 24 Vdc and turns
at 80 r.p.m.

These containers are equipped with a plastic
worm driven by a 24 Vdc motor which pushes
the product down towards the container outlet.
There is also a cogwheel that rotates around a
stainless steel shaft, driven by the worm, to
stir the product and prevent caking.
The chocolate and milk containers have a
stainless steel support with a spring that
causes the cogwheel to vibrate when it turns.
This vibration prevents the chocolate from
caking and forming cavities due to humidity.

VERY IMPORTANT: Soluble product containers are placed on the left-hand side of
the cabinet and the coffee bean container on the right. They should be 1st fitted on the
relevant dispenser motor and 2nd fixed in place by anchoring the front container flange
n the holes at the base of the machine, applying a slight pressure frontally.
Beater motor & steam exhaust
The beater assembly (fig. 14) mixes the water and the soluble product to ensure a
uniform end product. It is also equipped with an exhaust system to remove the steam
generated when the beaters are mixing the products. The steam formed is exhausted
from the machine (at the back) with a vacuum motor (fig. 15).

The product beating process is as follows:
► The boiler solenoid valve corresponding to the beater to be used for the soluble
product chosen is enabled. The amount of water needed is determined by the
programmed dose for that product and defined by the volume of water going through the
volume counter. The water reaches the beater funnel nozzle through a silicone tube. The
nozzle is placed tangentially to the funnel to better drag the soluble product along.
Coffeemar
G-250
// Coffee
MNP116M01GBV00 Date: 09/04/2013 Rev. 1 PAGE 14 OF 95
► The dispensing motor of the container with the required soluble product starts. These
are 24 Vdc motors turning at 80 r.p.m. which turn the worm that pushes the product
through the elbow to the beater funnel.
► The water and the soluble product are mixed in the beater funnel. The water drags the
soluble product and both fall into a recess between the beater elbow and the beater
paddle, which turns at about 16,000 r.p.m. driven by the beater motor which works with a
current of 220 V (110-125V). The centrifugal force created by the paddle pushes the
mixture to the product dispensing nozzles, located in the rotating arm.
The beater assembly has a gasket made with a flexible material that prevents the liquid
from reaching the motor. It is also fitted with a spinner so that, should the liquid get pass
the gasket, the mixture will be expelled from the beater, ensuring the motor is not soiled.
Product delivery collector
Made of ABS, the collector has 4 nozzles for the food grade silicone tubes that deliver
the end product coming from the 3 soluble product beaters and the espresso assembly,
which are located in the collector nozzles.
It is put in place by fitting the collector table at the back, placing the lower front part on
the vault support and an anchoring bushing on the right side of the machine (see fig. 16).
Fig. 16
Mill
The coffee mill assembly is the mechanism that grinds the coffee beans and turns them
into ground coffee. When a customer requests an espresso coffee, if there is nothing
wrong this mechanism will be enabled. It consists of two alloy steel grinding wheels. The
beans are trapped between the two wheels and ground. The mill includes an automatic
grind adjustment that works with a cogwheel that turns on the grinding wheels obtaining
a coarser or finer grind (it is adjusted approximately every 100 servings. The automatic
grinding adjustment motor adjusts for a finer grind to compensate for the faulty

adjustment of the grinding wheels due to wear. You can also change the grind level
through machine programming.
Note: The grinding wheels have a service life of about 35.000 servings.

The coffee mill is driven by an electric motor (220 V, 50 Hz) (110-125 Vac, 60 Hz) that
turns at 16000 r.p.m The speed is limited by a reducer to 2000 r.p.m.
Once the beans have been ground, the coffee is sent to the coffee doser. This doser
measures out the mount of coffee to be brewed. A microswitch triggered by the flap
which in turn is moved by the ground coffee, stops the coffee mill motor and enables the
coil that opens the doser.
Note: A piece of wire at the coffee mill outlet separates the ground coffee so it does not
cake in the doser (see fig. 18).

The range of this mechanism is 3 g (0.066 lb.) of coffee, which is the difference between
the minimum quantity of coffee to be used (5 g – 0.011 lb) and the maximum quantity (8
g - 0,0176 lb), with a tolerance of ±0.5 g. (0,0011 lb) This quantity is regulated with a
manual wheel with a pointer that has a factory setting of approximately 7 g. (0,0154 lb)

Users can modify this quantity
as they see fit. To do this,
press the black pushbutton
located on the front of the
doser (see fig. 19) and turn it
counter-clockwise to reduce
the amount of coffee beans
ground or clockwise to
increase this amount. Each
division on the dial
corresponds to approximately
0.25 g (0,0006 lb), depending
on product, humidity, etc.
The ground coffee dose from the doser is sent to the coffee brewing assembly.

MNP116M01GBV00 Date: 09/04/2013 Rev. 1 PAGE 17 OF 95
Brewing assembly
This is the mechanism that pushes the water through the coffee. It uses a mechanical
cam lever system driven by a 43 W motor, with a speed of 8 r.p.m and a power supply of
220 V and 50 Hz (110-125 Vac, 60 Hz) that follows the working cycle described below:
1. When the doser coil is enabled it opens the doser and the coffee falls through gravity
inside the coffee assembly infusion chamber.
2. The coffee assembly goes into to infusion position (it is initially in standby position).
This takes place when the motor for the relevant assembly is activated to move the lower
filter up to the closure of the infusion chamber to compress the ground coffee into a puck.
3. The water comes out of the air-break, where it is kept at a constant level, and it is
pumped into the boiler. The same amount of water, already heated, is sent to the coffee
assembly after a solenoid valve is enabled. The water comes into contact with the coffee
in the chamber and infusion takes place. The coffee is then sent to the cup.
4. The used grounds puck is discarded through the coffee grounds outlet.
5. The coffee assembly returns to standby position and the cycle is complete.
This assembly allows for brewing of coffee doses between 5 g and 8 g ±0.5 g. (0,011 lb
and 0,0176 lb ±0,0011 lb) Depending on the amount of coffee desired, the brewing
chamber has two positions, to allow for proper compression. It is recommended that, for
amounts between 5.5 g (0,0121 lb) and 6.5 g, (0,0143 lb) the brewing chamber be
placed in the lower position and for quantities between 6.5 g (0,0143 lb) and 7.5 g,
(0,0165 lb) in the upper position.
To change the position of the brewing
chamber, loosen the four screws that hold
it in place and move it, fitting its teeth into
the desired position and then tighten the
four screws again (see fig. 20).

The brewing assembly has two metal filters located as follows: The lower filter is located
in the infusion chamber, and the upper filter in the brewing chamber. These filters should
be cleaned periodically. To do this you need to remove the coffee assembly, following
the instructions indicated in section 8 of this manual and put the assembly under running
water, making sure the filters are properly washed.

IMPORTANT: When you have removed the brewing assembly for cleaning or other
purposes, when you are going to put the assembly in place again you should place it so
that the plate that joins the moving wheel and the infusion chamber so it can move
coincides with the arrow that appear on the cover of the coffee assembly (this way, the
cam that moves the assembly will coincide with the driving wheel). Otherwise, the
brewing assembly may get stuck and the machine will be left out of service.
It is also important that the infusion chamber and brewing chamber O-rings be properly
maintained and replaced whenever a loss in brewing pressure is detected.
Brewing assembly gasket and sprinkler replacement
Release the top outlet assembly (1) by removing 4 screws (11) and pull out two pivots
from the brewing assembly (12). To replace the sprinkler (9) you only need to remove the
screw (10). You can also easily remove the O-ring (8).
To access the O-rings (5) release the compressor piston clamp (2) by turning it and
applying enough strength to prevent the spring (3) that is inside from coming out.
Remove the shaft (4) and then replace the O-rings (5).
The brewing chamber assembly top outlet assembly (14) can removed from the brewing
assembly (12) by removing two circlips (13) and loosening the screws that are closest to
be able to pull out the shaft and the yellow nut.
Once you have removed this assembly (14) you can start by pulling the piston
attachment rod (23) using a suitable flathead screwdriver. This releases the piston
support (22) to remove the spring (21). Remove the shaft holding plate (20) and the two
shafts (17) in order to remove the washer (19) and O-ring (18).
The O-ring (8) can be replaced once you have removed the brewing chamber piston
shaft (15). Change the sprinkler (9) by removing the screw (10) and replacing it with a
spare sprinkler.
To change the O-ring (5) that is housed in the water inlet pipe, remove the brewing
chamber clamp (24) by rotating it, and replace the gasket with a new one.
Make sure that you do not loose the closure O-ring on the lower part of the de la brewing
chamber when removing the plunger.
There are various aspects that have an influence on obtaining good espresso coffee
which should be taken into account when operating the machine. These factors are:

There are various aspects that have an influence on obtaining good espresso coffee
which should be taken into account when operating the machine. These factors are:
1. The quality and type of product used (roasting level)
2. Product quantity. This is defined by the doser and can be modified using the dosing
wheel. The machine is factory set for approximately 7 g. (0,0154 lb)
3. The water temperature. The temperature of the water inside the boiler can be modified
by accessing machine programming (section programming working temperature). You
should take into account that the water temperature at the brewing assembly inlet is less
than the boiler water temperature that you program, due to contact with colder
components. It is recommended that, to make a good coffee, the water should enter the
brewing assembly at about 95 °C (203 °F).
4. Grind level. If the ground coffee is too coarse, the water will go through the puck
without extracting the necessary coffee, while if it is excessively fine, the water will have
problems in going through the puck and the brewing time will be too long. The adequate
grinding level is that which results in the water going through the cups at a pressure of
Coffeemar
G-250
// Coffee
MNP116M01GBV00 Date: 09/04/2013 Rev. 1 PAGE 20 OF 95
0.7 to 0.9 MPa (the machine is factory set to achieve this pressure level for a 7 g (0,0154
lb) puck).
Note: The assembly brews at constant minimum pressure above 0.7 MPa from the first
drop to the last.
Boiler
This is the tank that stores the hot water supplied to the coffee assembly and to the
soluble product mixing beaters. This tank is made of brass with an approximate capacity
of 330 cc. The water is heated using an 1.100 W, 220 V (110-125V) heating element.

The water dose is determined by two 3/2-way solenoid valves, one for the beater
assembly and the other for the coffee assembly.
The boiler consists of a brass body with stainless steel inserts in the solenoid valve seats
to prevent scale accumulation in the more sensitive areas with a 220 V (110-125V)
power supply. The solenoid used to supply water to the espresso assembly enables the
water left in the Teflon tube after brewing to flow back after the valve closes. This outlet
communicates with the waste bin. The other outlet is directly connected to the coffee
assembly.
Dosage of the water of the various products available is achieved by controlling the
amount of water using a volume counter located behind the air-break. This allows for a
very accurate control of doses, while ensuring that the pressure boiler is always full of
water, as the same amount of water that goes out comes in.
On the side of the cover there is a sensor for controlling water temperature. This sensor
is programmed to keep water boiler temperature at 90 °C (194 °F), although this
temperature is programmable. The two covers are kept air-tight with a silicone O-ring.
Should the temperature sensor fail, the boiler has the following control systems:
Coffeemar
G-250
// Coffee
MNP116M01GBV00 Date: 09/04/2013 Rev. 1 PAGE 21 OF 95
► Should the temperature control system fail
(memory loss, sensor failure, connection failure,
etc.) the boiler heating element will heat the
water without control and, therefore, the brass
cover walls. To prevent the temperature from
reaching dangerous levels, there is a bimetal
bipolar thermostat affixed to the back of the
boiler with two screws. This sensor is adjusted
to 120 °C (248 °F) and puts the machine out of
service when the boiler metal walls reach this
temperature. This sensor can be reset manually
by pressing the red button. To do this, open the
brewing assembly door by removing the screw
that holds it in place and you will be able to
access the reset button.
Fig. 23
► If the temperature of the water in the boiler is more than 10 °C (50 °F) below working
temperature, the machine will not serve any drinks.
You should take into account that, when you first start the machine up or when the water
circuit has been emptied for maintenance or other reasons, the heating element will not
begin to heat up the water until the air-break is full.
During the initial setup of the machine or when the boiler has been emptied for
maintenance purposes, it is essential to ensure that the boiler is filled, either
automatically, using any of the machine’s available systems, or manually by carrying out
a manual washing operation. To ensure it is completely full, you should check that water
comes out through any of the product delivery elbows in the rotating arm.
The pressure boiler is located at the back of the cabinet. If you need to access it, follow
these steps:
► Remove the screws that hold the back cover of the cabinet and remove the cover.
► This way you can easily access the pressure boiler to carry out any work.
If you need to remove the boiler, disconnect all cables feeding the solenoid valves, the
heating element (through the safety klixon) and all the other control elements.
Disconnect the water circuit silicon tubes leading to the boiler and loosen the self-tapping
screw that joins the boiler to the espresso assembly and remove the boiler.

Volume counter
The function of the volume counter is to measure the amount of water coming in to
identify the programmed serving amounts.
Inside, it has a blade with two magnets inserted in it so that the water that enters the unit
moves the blade and an integrated circuit on the lid detects that water is passing through
and sends the information to the control card.
Every 13 pulses red by the counter are the equivalent of 10 cc of water.

Air-break
The air-break is a tank that collects the water that comes into the machine from mains.
The capacity of this tank is about 300 cc. Its main purpose is to store water at
atmospheric pressure and ambient temperature. This ensures that the supply of water for
the preparation of soluble drinks is constant. If the water were taken directly from water
mains, changes in pressure would create deviations in the accounting of the water used
in each serving. This tank feeds the pressure boiler through a food-grade silicone tube
using a pressure pump.
It is fitted with a control system to monitor water level using a floater. When the desired
water level is reached, the floater blocks a light beam generated by the photocell system
and sends a command to shut off the water intake from mains. When a new sale is
made, the floater descends, the light beam is unblocked and the water intake solenoid
valve opens until the air-break fills up again.
This tank also has a safety system operated by a microswitch which is only closed in
case the abovementioned water level control system fails. Water intake is closed before
the water in the air-break reaches the runoff level, putting the machine out of service.
Should both water level systems mentioned above fail, the water will reach the runoff
level and empty into the waste bin. There is another control system in the waste bin to
prevent uncontrolled water intake from mains. This system consists of a floater which
puts the machine out of service when the bin is full.
The reduced capacity of the air-break allows for precise control of the amount of water
present in the water circuit of the machine, so that in general, after each sale, the water
level is below the minimum and requires water from mains. This way, since the amount
Coffeemar
G-250
// Coffee
MNP116M01GBV00 Date: 09/04/2013 Rev. 1 PAGE 24 OF 95
of water needed is very small (that corresponding to one sale) the water temperature in
the boiler is allowed to experience very small fluctuations.
The machine is programmed so that, should the air-break water level not appear to
descend during consecutive sales totalling 200 cc of water, so no water is taken from
mains, the machine will be put out of service (air-break floater stuck). To solve this
problem, lower the floater manually and turn the machine on again.

The air-break is located at the back of the cabinet. To access it, remove the screws that
hold the back cover of the cabinet and remove the cover from the support pins.
Some dirt and scale deposits may appear at the bottom of the air-break. In order to avoid
the problems that might ensue from this for the proper operation of the water volume
counter, a food-grade plastic filter has been fitted in the water pipe from the air-break to
the volume counter inlet.
Electronic control system
It consist of several printed circuit cards:
• Control card, which governs all of the machine’s movements, as well as
programming of options and product audits, and also power sources that supply
appropriate voltages for logic control, to move the tray motors, to supply peripherals
on bus 485. The program is recorded in FLASH memory.
• Display card, which has the LCD display, the buzzer control and connections for the
product selection pushbutton panel and the programming pushbutton . This is a
peripheral unit controlled by the control card with which it communicates using the
485 bus. The display can show animations.
• • Relay card, which governs the heating element of the pressure boiler .

Compact (MDB)
• MDB compact coin changer without coin return motor (see MDB manual).
• Communications between machine and compact take place under an MDB protocol.
The machine behaves as master unit while the compact acts as slave unit.
When the machine is in service, the display shows the
time. In single sale mode, only coins or banknotes
having a value that can be returned and that does not
exceed maximum credit will be accepted and the
maximum credit you can insert cannot exceed maximum
recovery.
Additionally, maximum recovery is updated automatically
with the highest price in case such price exceeds the
value of maximum recovery.
To ensure proper machine operation you should check
that maximum return and prices are properly
programmed. In single sale mode you need to insert
money until you reach or surpass the price of the desired
product. When you enter the product selection from the
keyboard, the display shows the price of the product. If
this price is less than or equal to the money inserted, if
the machine is not out of that product and if there is
enough change, the sale is allowed.

USB options
The machine has a USB type A connector at the back of the display. You can connect a
USB mass storage device (pen drive) to the connector and use it to store and read data.
Limitations to take into account:
► The pen drive should be formatted to FAT or FAT16. No other format is valid.
► Only files in root directory are recognised and used.
► The machine has limited functionalities in the use of the pen drive. A pen drive with
good access speed is recommended, otherwise, the machine may not behave
appropriately.
► When reading from or writing to the pen drive, the machine cannot access the display
or the pushbutton panel. Therefore, there are times when keypad pulses will not be
recognised by the machine.
Coffeemar

► It works in fixed mode with 8 characters for the name and 3 for the extension.
Incomplete names or extensions of less than 3 characters may result in a faulty display
of file names and/or extensions.
► If there is no pen drive connected and read by the display, when you enter the USB
options the following message appears:
No action is allowed except
to exit.
Using the pen drive
To prevent faulty views and other artefacts, do as follows when using the USB drive.
1. Open the machine and press the programming pushbutton to call up the main menu.
2. Insert the pen drive in the connector.
3. Wait a few seconds until the following message appears:
LABEL being the name used to label the pen drive when it was formatted.
4. Wait a few more seconds until the previous message disappears. This means that the
display has read the file system contained in the pen drive and can now access their
presentation. The time it takes to read the file system will depend on the pen drive’s
access speed and the number of files contained in it. During this time, the machine will
not respond to the keys.
5. Once the message has disappeared, you can access the USB submenu in the
technical menu.

5. Installation and start-up.
5.1. Installation
Do not install the machine near active heat sources (heaters, radiators, etc.). Leave a
distance of at least 7 centimetres between the back of machine and the wall or other
items.
IMPORTANT: It is important for the machine to be level, as it should operate in a
vertical position, both laterally and back to front, located so the mains plug is
accessible and with a maximum inclination of 5% (~2 °).
Adjustable levelling feet
Once the machine has been placed in its permanent
position, raise the front and level the door using the left
and right adjustable levelling feet (see fig. 39). With this
system you can help to level the door perfectly, thereby
preventing scraping it.
Fig. 39
5.2. Connection to mains
The machine is set up to work with a single-phase voltage of 230 V, 50 Hz (110V, 60Hz)
protected with 10 A and 15 A fuses.
Before connecting the machine to mains, please make sure that mains voltage coincides
with the data which appear on the machine identification label (which is affixed to the
inside of the machine door) with variations under ±6%.
► The supply line should be appropriate for the distributor’s usage needs.
► Use an earth leakage protection system.
► Position the machine so the mains socket is accessible.
The mains socket should be compatible with the machine’s plug. If it is not, it should be
replaced with a compatible socket.
The connection should include a grounding connection in compliance with regulations.
IMPORTANT: It is very important that the electrical circuit has an appropriate
ground connection which meets current regulations. If in doubt, have a qualified
technician check the installation.

MNP116M01GBV00 Date: 09/04/2013 Rev. 1 PAGE 38 OF 95
The machine is supplied with a power supply cable,
depending on the country and the
supply voltage
Do not use adapters, extension cords or multiple socket devices.
Before powering the machine, make sure that you have connected the machine to water
mains and that the stopcock is open.
Note: Jofemar S. A. does not assume any liability should the above instructions not be
headed in whole or in part.
If the power cable is damaged, it should be replaced by qualified personnel to
prevent hazards.
To replace the power supply cable, follow the instructions below:
► Remove the control card protection lid.
► Disconnect power supply cable phase and neutral wires connected to the filter, as well
as the ground connection.
► Use a no. 7 socket spanner to remove the nut that holds the power supply cable strain
relief.
► Remove the wiring hole gasket using an appropriate tool and remove the power
supply cable.
Install the new power supply cable following the steps described above in reverse.
5.3. Connection to water mains
Before connecting the machine to water mains, please take into account the following
requirements for the water supply:
► Please ensure water is drinkable by obtaining relevant certificates from a testing
laboratory.
► Make sure water mains pressure is between 0.05 and 1 MPa. With pressures under
0.05 MPa it will be necessary to install a pump. If the water mains pressure is above 1
MPa, you will need to install a 0.25 MPa pressure reducer in the machine’s water supply
hose. In any case, it is always advisable to install a pressure reducer if the water supply
pressure is likely to experience significant variation.
► Make sure there are no impurities in the water. Make sure there are no impurities in
the water. If the water is very hard (above 20 ºf) it is advisable to install a water softener
or a resin or ion exchange water softener with a capacity that is appropriate for the
machine’s water consumption. The water softener should be periodically regenerated
according to the manufacturer’s instructions (these water softeners are optional).
Coffeemar
G-250
// Coffee
MNP116M01GBV00 Date: 09/04/2013 Rev. 1 PAGE 39 OF 95
Note: It is advisable to install a stopcock in the water supply, outside the machine, in an
easily accessible location.
For the connection to water supply network, a new hose must be used; never re-use old
hoses. Removable hose kits used to connect devices to water supply networks must
meet IEC 61770 regulation.
After the above requirements have been met, connect the 3/4” gas connector of the
machine’s water inlet solenoid valve to water mains, using a food grade hose with a
minimum internal diameter of 6 mm (0.236”), appropriate for withstanding the water
mains pressure.
As this device have to option to be connected to water supply network, the elements
used to make such connection must meet the national regulations of the country where it
is installed.
5.4. Filling the water circuit
Make sure the machine water supply stopcock is in the open position.
Place the waste bin on the guide located at the bottom of the machine. Place the waste
level sensor floater which hangs from a chain connected to the waste level sensor switch
inside the bin.
Check that the air-break manual emptying
silicone tube shutter is applying pressure
on the silicone tube to ensure that the
water does not go directly into the waste
bin (see fig. 40).

MNP116M01GBV00 Date: 09/04/2013 Rev. 1 PAGE 40 OF 95
The machine will automatically carry out an internal check. It will first move the rotating
arm to ensure it is working properly and then leave it in standby position. The coffee
assembly cam position is also checked. The cam will move until it is in the correct
position to begin the assembly’s operating cycle.
It will then check whether there is water in the air-break. Since it is empty, it will open the
water intake solenoid valve and filling will begin. Once the air-break has been filled,
water will begin to pass through the air-break into the pressure boiler, through a pump
located between them. While the boiler is filling up, several things take place: water
continues to go into the air-break because a micro-switch detects that the water level is
coming down. At the same time, a solenoid valve in the boiler opens to prevent excess
pressure in the boiler. Thus, when the boiler is full, water will begin to come out through
the solenoid valve. The valve will remain open for a few seconds so the boiler is filled
correctly.
IMPORTANT: If, after this operation, water does not come out of the soluble
beaters, the pressure boiler has not filled complexly, so the machine will have to be
cleaned manually until water comes out of the beaters .
Thus, what can mainly be observed is that: the water inlet solenoid valve that lets water
into the air-break will open as often as necessary, until the air-break control system
detects that the water circuit has reached the required stand-by level.
Note:
The machine will be left out of service if after 10 minutes the air-break has not
filled up. This may be because the stopcock is not open or because the emptying tube
shutter is not closed and the water is going directly into the waste bin.
Once this level has been reached, the boiler heating element will begin to heat the water
until it reaches working temperature.
5.5. Cup loading
Only cups specifically designed for automatic drink dispensing machines should be used.
The cups should not be transparent or made in a photo-absorbent colour. This machine
is equipped to deliver cups of different sizes. These are classified in terms of their
diameter measured just under the top ring.

When you load cups for the first time (all storage tubes are empty) proceed as follows:
1. Check that the cup storage tube closest to the cup dispenser hole is centred above
this hole.
2. Remove the lid of the cup storage tube assembly
3. Insert the cups in all tubes except for the tube immediately above the cup dispenser
hole.
4. If there are now cups present when the power is turned on, this will be detected by the
machine and it will rotate the tube assembly until it finds a tube with cups.
5. Fill the empty tube with cups.
6. Press the button located on the cup dispenser to manually drop cups, one by one,
until a cup reaches the product filling position.
7. Put the cover back on the cup storage tube assembly.
Note: When the machine is connected to mains and the sensor does not find any
cups, the distributor will rotate the columns eight positions in a row. If no cups are
detected in any tube, the message “cups missing” will appear on the display and the
machine will be left out of service.
5.6. Stir-stick loading
Follow the steps below to load stir-sticks in their container.
1. Remove the stir-stick storage slide counterweight.
2. Insert a stir-stick bundle, held together with a ribbon in the slide.
3. Hold the stir-stick bundle with one hand while you cut the lower part and pull the
ribbon upwards.

5.11. Updating the machine program
The control card of the machine has been designed to use flash technology. This allows
you to update the program in the card without needing to remove any part of the
machine, as this task can be done through a 180 degree 5 pin DIN connector in the RS232 port. Program updating can be done through a PC or a J-120 reprogramming card
drive.
■ USING A PC
Follow these steps to update the program:
1. With the machine turned off, connect the PC to the machine using the RS232 cable.
2. Choose the program to install in flash memory:
• The program files should be stored in the subdirectory of the hard drive
corresponding to the COFFEEMAR G250 machine.
• Run the PC program. Choose the menu option FLASH – RECORD COFFEEMAR G250 and choose the .BIN file to record.
3. Turn the machine on.
4. When the program has been updated, a message will appear on the PC screen
indicating that the flash memory has been successfully recorded.
■ USING THE J-120 REPROGRAMMING CARD DRIVE
Follow these steps to update the program:
1. Insert the reprogramming card in the desktop card drive, which should be turned on.
2. Choose the flash recording application:
• The program files should be stored in the subdirectory of the hard drive
corresponding to the COFFEEMAR G250 machine.
• Run the PC program. Choose the menu option CARD – RECORD COFFEEMAR G250 and choose the .BIN file to record.
3. Once the card has been recorded, take it out of the desktop card drive and insert it in
the reprogramming card drive..
4. With the machine turned off, connect the card drive using the machine's 180°, 5-pin
DIN connector.
5. Turn the machine on. First, the card drive's green LED will light up and then, while the
program is being recorded, the red LED and the green LED will blink.
6. When the program has been updated, the card drive's green LED will blink. At this
point you can disconnect the card drive from the machine.
■ USING THE EASYFLASH REPROGRAMMING DEVICE
Follow these steps to update the program:
1. With the machine turned off, connect the EASYFLASH device to the machine using
any of the cables supplied.
2. As soon as the program is loaded, it will load the data from the file TYPES.DAT for the
machines with which you wish to communicate.
Coffeemar
G-250
// Coffee
MNP116M01GBV00 Date: 09/04/2013 Rev. 1 PAGE 46 OF 95
3. The first thing the program requests is the type of operation you wish to carry out.
- Recording a program in flash memory.
- Erasing the card’s flash memory.
- Identifying the program recorded in a card.
4. After choosing the operation, you have to select the machine with which you wish to
communicate.
5. You need to select the file you are going to record.
-The program can work with two standard reference file formats, .HEX (Intel) and
.BIN. When the program has more than one bank, the file extensions will be .H00,
.H01, .H02 (or .B00, .B01, .B02 ) and so on until all banks are completed. In
these cases, the program will only show the file of the first bank (.H00 or .B00).
-When you select a file, if the extension is .HEX or .BIN the program will know that
there is only one bank, while if it is .H00 or .B00 it will search for files with
consecutive extensions until it does not find any more (maximum .H09 or .B09) and
the number of files will be the number of banks recorded.
6. After all the data has been recognised, the program will begin the chosen operation.
- This process is divided in two parts, the first is erasing the flash memory and the
second is the program recording.
7. When the recording program has finished communicating with the machine, a new
window will appear showing the result of the process.
(For more information, consult the manual of the EASYFLASH reprogramming device)
5.12. Machine reset
The machine is factory configured with the initial values for product pushbutton panel and

This option allows you to indicate which options are going to require entering a password
to be able to access it. This option always appears but if it is protected, when you try to
access it, the machine requests the access password. If you do not enter it correctly, you
cannot access the option. If you are going to work with passwords, do not forget to
protect this option and the previous one with an access password so one cannot consult
the password.

VERY IMPORTANT: In case of error when selecting the file, etc. the machine could
lose all programming.
When you are in CREATE BACKUP
It displays the list of files to select the file that you wish to use for your copy. If you
choose an existing “.bak” file, its content will be replaced with the current content. At the
end of the list, there is an exit line. If you select this line, you will pass to writing the name
of the new file that you wish to create as a backup. See the “currency programming”
option for a description of how the name is written and you go on to the next stage.
The number of characters in the name is 8, if you write more than 8 it is truncated and if
you write less than 8, the empty spaces are filled with “_”. The file is written immediately
and a beep sounds every so often to let you know that the backup file is being written.
Once the file is complete, the machine displays the message “FINISHED”. At this time
some seconds may elapse before the machine responds to the keys again.

to end the recording.
When the machine detects it, it will stop sending data to the USB drive, although you
have to wait for the pen drive to record all the data for the machine to detect the pulses
again. This normally takes about 15 seconds but low-quality pen drives can produce
freezes of up to 1 minute. If you think the machine has frozen, wait at least 2 minutes
before turning it off because, if the file has not been closed when the machine is turned
off, the data may not be accessible.

EASYFLASH reprogramming device
The main function of the “EASYFLASH” reprogramming device is to run applications
that help manage the Jofemar product range. It is thus an independent, compact,
manageable instrument that allows the user to carry out tasks such as reprogramming
the software of the machines, reading audits, monitoring processes, storing information,
etc.
It is accessible through a USB bus, so modern operating systems (starting with Windows
XP) do not require installing drivers to access its file system. All you have to do is
connect it to a USB port for the operating system to recognize it.
Thanks to the use of batteries, it is very compact and easy to manage. To charge the
batteries, no external charger is required and the batteries are recharged when the unit is
connected to a USB port or to a vending machine that is on.
It has an application called Monitor, which is basically an operating system. The Monitor
allows you to control available resources. In addition to the Monitor there are
Applications, which are programs that are run in the device that use resources to carry
out certain functions.
Coffeemar
G-250
// Coffee
MNP116M01GBV00 Date: 09/04/2013 Rev. 1 PAGE 83 OF 95
The Monitor allows you to load up to 4
applications in the main memory from
among those available in the SD memory
card.
You can determine the version that is
currently running in your device by looking
at the top of all the windows of the main
menu of the Monitor. The format is
vXX.YY. A correct version should have
the value 00 for YY. If this is not the case,
please contact Jofemar Technical Support
Service to obtain a stable version.

Water inlet pump kit
If the machine cannot be connected to water mains or the quality of available water is not
appropriate, the machine can work independently with water supplied from a 25 litre
bottle.
To take the water from the bottle and take it to the boiler, you need a 220 V pressure
pump. The pump is attached to the interior of the cabinet with an a Al-Zn plate screwed
with two self-tapping screws in two holes located below the mains water inlet solenoid
valve. The pump is mounted on shock-absorbing brackets by inserting its two ends
inside the brackets. First, insert the longest end (the one with the coupling) up to the
groove and then the shorter end. Connect a 900 mm (35.433") long, 9 mm (0.354”)
external diameter and 5 mm (0.197”) internal diameter, food-grade silicone tube to the
end of the pump. This end of the tube has a spring to prevent water flow from being
blocked. The other end of the tube is inserted inside the bottle with a bushing that has a
stainless steel end.
Once the kit has been installed, connect the
pump’s free male thread 1/8” Aixia coupling
to the food grade silicon tube connected to
the water mains inlet solenoid valve and
connect it to the pump.
Fig. 55
Note: The pressure pump is equipped with overheating protection. It is important to
mount the spring against the pump so that it will work as a clamp and the pump tube
does not come off.

Water softener
Many waters contain dissolved minerals that make them hard (calcium or magnesium).
These minerals build up scale deposits. For the coffee machine to work properly, as well
as to make maintenance operations easier, it is necessary to use water with a low
content of scale. Otherwise, the scale accumulates on the various machine components
and may obstruct conduits and deteriorate parts or render them ineffective. If you cannot
connect the machine to a soft water supply, a water softener will eliminate hard water
problems by exchanging calcium and magnesium ions with sodium ions, thanks to the
resins of the water softener filter. It is advisable to use a water softener filter for water
with a hardness level above 20 °f. The Jofemar coffee machines can be fitted with an
optional ion exchange resin filter water softener. These filters are based on the capability
of the resins inside the water softener bottle to exchange sodium (Na) ions with calcium
and magnesium ions in the water. With use, the resins become saturated with scale ions
and need to be regenerated. This is achieved by putting common (kitchen) salt in the
water softener bottle and passing water through the resin, so the salt’s sodium is trapped
in the resin and the calcium and magnesium ions are discharged. How long a filter will
last before it needs to be regenerated depends on the water’s hardness. The number of
approximate servings (which depends on how much water is needed for each product)
that these filters can handle are:
WATER HARDNESS (°f)
No. OF SERVINGS
20 °f 18.000

Fig. 56
Flavour filter
VERY IMPORTANT: This kit should be installed outside the machine, before the
inlet solenoid valve. No couplings or connectors are included for the solenoid valve.
This type of filter is meant to provide optimal quality water for hot drink dispensing
machines.

They are pre-coated filters using active carbon dust to remove all impurities larger than
1 µm, as well as undesirable flavours and smells. This results in a better quality
product that also reduces health hazards and lengthens the working life of machine
parts.
This type of filter also prevents scale formation, provided the hardness level of the water
supply of the machine is less than 20 °f (French degrees). If the water used to prepare
the various drinks dispensed by the machine has a higher level of hardness, the water
softener kit is recommended.

8. Cleaning and Maintenance
Cleaning the machine.
To ensure the machine works properly at all times, we recommend that the following
components be cleaned periodically:
►Fort he cleaning of machine parts in contact with food it is required the use of
chlorinated prodcuts based in linear alkybenzene sulfonate (LAS) and [sulfatos de
cadena ramificada (ABS)]
► The advertising and key panels should be cleaned periodically with a moist cloth or
sponge and a neutral product suitable for cleaning glass.
► In case of product spills, product containers should always be cleaned with a cloth
moistened with water.
► If there is a spill on a container, remove the container from the machine and clean it
using a cloth moistened with water, never with alcohol or acids. Dry it before replacing it.
► In general, keeping all internal areas that are visible to consumers clean increases
sales and improves the image of the machines.
► Do not clean the machine with a water jet.
► It is very important never to touch those areas powered at 220 V, such as the ballast
box, the power box and live cables. Access to these areas is restricted to qualified
personnel.
► Access to servicing area should only be permitted to persons with a knowledge of and
practical experience in the machine, particularly with regard to health and safety.
► To clean the exterior of the machine, use a moist cloth with warm water and dry with a
soft cloth.
► In case of persistent stains (grease, drinks, etc.), do not apply abrasive products. Do
not use a cleaning sprays! Use a solution of water and alcohol.

Cleaning the selector
The walls and ramps of the coin selector
where coins circulate should be cleaned
regularly (see fig. 58) with a soft brush
and a moist cloth.
Fig. 58
Cleaning beaters and water circuits
Before the machine is put into operation, the coffee assembly, the beaters which mix the
products and the water circuits need to be cleaned to ensure the product is sold in the
most hygienic conditions.
First, the water circuit should be cleaned to get rid of any dirt in the boiler and the rest of
the water circuit. The following steps should be followed for manual washing:
► Press the machine programming button, which is located inside the door, behind the
cup storage tubes, and then press the manual cup dispensing button, located on the cup
dispenser assembly. To repeat the washing operation just press this button again.
You then need to ensure that any parts which come into contact with foodstuffs when the
soluble and water are mixed together with the beaters are clean and that any water used
in washing out the water circuit does not remain on the beaters. To do this, you have to
individually clean and disinfect each part. To do this, follow the process outlined below:
► Remove the soluble product containers which are located in the beater assembly
(figure 59) and place in a clean, disinfected place.
Press the container towards the inside of
the cabinet and, once the tabs are free,
pull upwards and forwards. Follow the
same procedure with the remaining
containers.

Follow the same procedure for each of the beaters on the machine.
Prepare an appropriate container with a basic solution of chlorine-based detergents,
which can be found in shops which sell pharmaceutical products.
To disinfect the parts of the beater and product containers, submerge them in the
prepared solution for about 20 minutes. To clean them effectively you may need to use a
brush or similar implements.
After disinfection, dry the parts carefully with compressed air, a dryer or disinfected
cloths. Then reassemble the beater parts in the machine following the above steps in the
reverse order.
Replace the soluble product containers
Remove the espresso coffee brewing assembly. To do this, open the door and cup, stirstick and sugar assembly and then follow the steps detailed below (see fig. 63):
► Remove the assembly attachment piston (A), by turning it counter-clockwise. After
unscrewing it from the thread that joins it to the lid, remove the assembly until the three

9. Recycling
When you need to discard packing materials, please find out about how they can be
recycled.
Do not dispose of electronic circuits as domestic waste as many of the materials
used to manufacture its components are recyclable.
To manage the equipment as waste once the client has decided to dispose of it,
Jofemar has set up a collection system with an Integrated Management System. Please
consult us for information about recycling.
10. Environment
Saving energy contributes to preserving the environment and, in the long run, helps save
a considerable amount of money. This section contains advice on optimising the
machine's use of energy as much as possible.
► The machine should be in a cool, dry, well-ventilated location, so a place with these
characteristics should be chosen within the premises.
► Direct exposure to sunlight should be avoided. If necessary use a shade or parasol.
Throughout the design process, efforts have been made to ensure that the machine has
a minimum environmental impact, in terms of the use of raw materials, assembly,
transport, service life and collection for recycling.
This section lists several major ways in which Jofemar fulfils its commitment:
► Lower energy consumption.
► Avoiding the use of a full cardboard box using beehive cardboard corner protectors.
► Recycling is a very important job that is everyone’s responsibility.
11. Regulations
Jofemar warrants that the
coffeemar G-250
range machines have been designed
and meet the requirements and other relevant provisions of Directives 2004/108/EC,
2006/95/EC and 2011/65/EU.
