1.2 - TAKING DELIVERY AND UNPACKING
The G10 and TWENTY coffee machines are housed in a box that protects it from being
jolted and broken.
Open the box and remove the moveable cardboard protection in order to be able to take
hold of the bottom of the machine with both hands. Lift out slowly and carefully.
Rest the machine on a flat surface or table for the preliminary operations.
First, check that the machine is complete and undamaged.
Also check that underneath the coffee dispenser unit there is the box containing the
accessories that come supplied with the machine. (See figure alongside).
Before connecting the coffee machine to the mains electric power supply, check that the
mains voltage is compatible with the technical specifications.
THE ELECTRICAL SYSTEM MUST BE EARTHED.
ACCESSORIES SUPPLIED WITH THE MACHINE
Page 12

1.3 - POSITIONING AND INSTALLATION
After checking that the machine is complete, locate it in the position in which it will be used. Ensure that the position is stable and safe and allows
enough space for carrying out the different operations (fitting the filter holder, obtaining hot water and steam).
The following appliances must be installed, adjusted and connected to the mains water and electric power supplies by qualified people in strict
compliance with the instructions contained in this manual.
To ensure that the machine works correctly and remains in proper working order, read this manual carefully, adhere to the standards which it sets
and refer to the diagrams it contains.
Place the machine on a flat surface that is out of the reach of children.
To prevent the machine’s being knocked, do not locate it in places where there is a lot of movement to and from or in narrow co rr idors.
Connecting to mains power supply
Connect the power cable to the mains by means of a 24 amp fused switch as shown on the label on the cable.
.
Connecting to the mains water supply
1 - cold water must be supplied to the machine;
2 - check that mains water supply pressure is compatible with the technical specifications for the machine;
3 - connect the drain pipe to the tank underneath the drip tray and do not make tight bends;
4 - Connect the 3/8" hose to the water softener. To do so, follow the instructions you find regarding the water softener
you intend to install. Use of the water softener is necessary to soften the water coming into the machine.
5 - ensure that there is an adequate inclination to enable water to drain away;
out
Page 13
38
1.4 - PRELIMINARY CHECKS
Check that: the electric plug has been inserted;
the drain pipe is connected to the mains water supply;
the drain pipe has been positioned in the manner specified in the instructions above.

SECTION 3 - USING THE MACHINE
3.1 - USING THE MACHINE
Place the main switch at position 1.
Turn the external water supply knob (where applicable) and turn on the steam tap, let the water flow into the water heater and check the level on
the reading scale. The
water level should come roughly half way up the MIN-MAX scale.
Place the resistance switch in the position 2.
Finall
For the Twenty 1unit model, there is no three-position switch available, only an
on/off switch. This model is equipped with a dual sensor that automatically
regulatesthe boiler's filling resistor.
y, shut off the steam tap.
The manometer will indicate that water heater pressure is between 0.9 - 1.2 bar.
Be very careful when dispensing water and steam.
DANGER OF BURNS.
To dispense hot water, turn the central knob
marked with the symbol .
To dispense steam, turn either one of the side handles
marked with the symbol .

ELE Model automatic electronic dosing
This reliable, high quality product ensures that Grimac’s new dosing system reduces assembly costs and the amount of space required.
The control panel controls both the coffee supply commands and the electronic controls. Each control panel is completely independent of the others.
If a control panel develops a fault, the others will continue to function as they are independent of one another.
Programming doses:
Press M5 for 5 seconds. The leds will light up, allowing the operator to use the machine.
- Press the required selector button.
- When the selected dose has been reached, press the same pushbutton again (storage in memory OK).
- Repeat the procedure for the other pushbuttons in order to complete all 4 doses.
To interrupt coffee dispensing, press the previously pressed pushbutton again.
For reasons of safety, no more than 3 litres or 4 minutes of continuous dispensing can be programmed.
TWENTY model
Only for Twenty model, the group system on the left programms the other groups present in the machine automatically.
In course of programming, first work at the group on your left and if necessary modify the other groups in order to have different coffee dose.
Page 21
46
On all models, the pressure gauge continuously indicates the internal boiler pressure and the coffee dispensing pressure in accordance
with the specifications set out in the table on page 9.
Adjust the pressure switch screws to adjust pressure inside the water heater.
Adjust the internal pump screw to adjust coffee dispensing pressure. This action is to be performanced during the coffee brewing.
If you have a visual sign, check in any time that the self-level is keeping the water level under control over the notch of minimum.
The coffee machine that you have purchased is fitted with a water heater in top quality copper. When the machine is in use, it contains
steam and hot water under pressure. DANGER OF BURNS.
Check the steam nozzles located on the sides regularly and clear them of any obstructions.
Page 22
47
SECTION 4 - MAINTENANCE
4.1 - CLEANING
Cleaning the filter:
after dispensing the last coffee, the filter holder and the filter must be thoroughly rinsed and cleaned with water. Replace the filter if it is too dirty or in too
bad a condition.
Allows keep the cup support grill and drip tray clean and tidy.
Use only water to clean.
Checks:
the machine does not require any particular servicing and checks. It is necessary only to regularly check the level of water in the water heater (L) ( if it
is available), the water heater level gauge (D) and the delivery pump pressure gauge (N).
OUTER CASING:
To keep the outer casing clean, use a sponge or piece of cloth soaked in special cleaning liquid (neutral detergent).
DO NOT USE SOLVENTS, POWDERS, ABRASIVES OR STEEL WOOL.

SECTION 5 - ACCESSORIES AVAILABLE ON REQUEST
5.1 - WATER SOFTENER
Use appropriate salts or kitchen salt (SODIUM CHLORIDE) Na CL to reactivate the water softener when necessary. Hard water is caused by calcium
and magnesium. Hard water is not harmful or a health hazard but it can cause scaling in the pipes and water collection tanks.
Water is hard when it reaches 30-45° on the French hardness scale and is very hard at above 45°. To measure the hardness of your water, use the
testing kits sold in chemists or at one of our after-sales service centres.
Using a water softener will save on electricity and maintenance costs.
M1-M2
Example of water softener
: tap handles
R : water softener pipe
S : drain pipe
U : drain connection
E : supply connection
POSITION 1 POSITION 2 POSITION 3
Place pipe S in a receptacle capable of containing 2 litres of water, place tap M1 in position 2. Drain the water from the water softener, remove the plug
and pour in 1 kg of kitchen salt. Clean the parts of that come into contact with the plug carefully and place the plug back in position.
Next, place pipe R in a position where water can drain out of it and turn the taps to position 3. Let the water flow until soft water emerges and then turn
the tap handle to position 1.

5.2 - CUP WARMER
Using the electric cup warmer
This system keeps the cups placed on the top grill at a suitable temperature.
The kit consists of:
1 cup heater panel with built-in double-insulated heater
1 connection harness
1 on/off switch (A) (see seat on left hand side of front panel).
