1 - Safety
Do not allow anyone to operate the machine unless suitably trained.
Keep the machine in good working order and do not allow any modifications to be made to it unless these
have been authorised by the manufacturer.
Before using the machine, read this section of the manual carefully; it instructs operators in the correct use of
the machine, and warns of improper use which may be hazardous.
1.1 Intended use
The PRE MIX system is used to cool and dispense cold pre-mix drinks.
The machines described in this manual are used to cool and dispense pre-mix drinks.
This appliance is intended to be used in defined "household and similar" applications such as:
- Holiday cottages and clients in hotels, motels and other residential type environments;
- Bed and breakfasts;
- Catering and applications other than retail or similar.
1.2 Improper use
These machines are designed for the use and conditions envisaged in this manual, in compliance with
Machine Directive 2006/42/EC.
The use of the dispensers for any purposes other than those for which they were designed is not allowed,
under any circumstances. Likewise, their use in any way other than that indicated in this manual is forbidden.
This unit can be used by adults without any experience and knowledge under supervision or after they have
been given instructions on the safe use of the appliance and have understood the risks. Children should not
play with the appliance. Cleaning and user maintenance must not be carried out by children.
This appliance is not intended for use by persons (including children) with reduced physical, sensory or
mental capabilities, or lack of experience and knowledge, unless they have been given supervision or
instruction concerning use of the appliance by a person responsible for their safety. Children should be
supervised to ensure that they do not play with the appliance
For the purposes of machine safety, and in accordance with the current legislation, any repair operations on
the machines must be carried out by the Service Centre.
• Do not alter or tamper with the internal dispenser components; if they do not work well, contact the
Service Centre.
• Do not place anything on top of the dispensers.
• Do not place the dispensers on top of any other object.
• Do not use liquids other than those indicated.
• If you believe the dispenser to be damaged, contact the Service Centre.
• Do not store explosive substances in this equipment, such as aerosol cans with a flammable propellant.

1.3 List of hazards
The following list of hazards draws attention to safety aspects which must be considered at all times by
anyone using the machine.
DANGER
CO2 (CARBON DIOXIDE)
CO2 bottles must always be stored in a well-ventilated place where the air can flow in and out.
Great care must be taken to prevent CO2 leaks throughout the system, including the gas bottles.
If a CO2 leak is suspected, especially in a small area, ventilate the contaminated area at once.
Persons exposed to high concentrations of CO2 will experience trembling, swiftly followed by
unconsciousness and suffocation.
DANGER
MAINS ELECTRICITY
Always disconnect the machine from the electricity supply before doing any work on it, to prevent
damage and health hazards.
DANGER
GAS CYLINDER POSITION
To prevent the risk of injury or damage, the CO2 bottle must always be kept in a vertical position
against a wall, held in place by a chain fixed to a bracket.
Do not expose the bottle to heat sources or very low temperatures.
If a disposable CO2 bottle is used, secure it vertically to prevent it from falling or overturning.
DANGER
REFRIGERANT
The refrigerant used is R290 or R134a. To verify which refrigerant is used, refer to the
compressor label inside the machine, and the nameplate.
In the case of R290 refrigerant, this is a natural gas with a high degree of environmental
compatibility, but it is also combustible. During the transport and installation of the machine, be
careful not to damage any part of the refrigerating circuit.
If the refrigerant spurts out, it may catch fire or cause injury to the eyes. If you notice a leak, do
not take any naked flames or potential ignition sources near the machine; air the room for a few
minutes.
CAUTION
Keep the ventilation openings on the machine and on the cabinet in which the system is housed,
free from obstruction.

PRE-MIX
WARNING
REFRIGERANT
To avoid the formation of an inflammable mix of gas and air in the event of a leak in the
refrigerating circuit, the size of the room where the machine is located will depend on the
amount of refrigerant used.
Never switch the machine on if you notice any trace of damage. If you have any doubts, please
contact CELLI S.p.A.
The room must measure at least 1 m3. for every 8 gr. of R290 refrigerant used in the machine.
The amount of refrigerant in the machine is shown on the nameplate.
WARNING
AUTHORISED TECHNICAL STAFF
Only technical staff skilled in the electric, hydraulic or refrigeration field may carry out work on
the machine. All wiring and plumbing components must comply with national and local legal
requirements (when replacing components, use only genuine parts certified by CELLI S.p.A.).
CAUTION
ELECTRICAL REQUISITES
The electrical circuit must be correctly earthed and connected by means of a suitable differential
safety breaker.
CAUTION
PLUG SUPPLIED
Connect the machine to the electricity mains using the plug provided.
If you need to replace the plug, use an equivalent model type-approved for the country of use.
CAUTION
SANITISATION
Before sanitising the machine, carefully read the instructions given by the sanitisation product
manufacturer and put on all the necessary personal protective equipment (gloves, masks, etc.).
Ensure that the premises are well ventilated.
The sanitisation operations should only be carried out by specialised technical assistance
personnel.
CAUTION
LOW TEMPERATURE
If the machine is exposed to temperatures lower than 0°C, the water inside could turn to ice and
damage the machine.

PRE-MIX
CAUTION
DRINKS CONTAINED IN PRESSURISED KEGS
To avoid any harm to people or damage to property, do not remove the cover from the keg until
you have discharged the CO2 pressure inside.
WARNING
REPLACEMENT OF THE POWER CABLE
If the power cable is damaged, it must be replaced by the manufacturer or their assistance
service or a similarly qualified person in order to prevent any possible risk.
1.4 Residual risks
During regular operating conditions the machine is safe. There are still residual risks, listed in the hazard list,
which are reduced if the machine is used correctly and according to the instructions given in the user’s
manual.

3 - Description of the machine
The TE/L range of machines (mod. 15 - 25 - 35 - 50 - 65) are coolers that dispense premix drinks
contained in suitable containers (kegs).
This manual refers to the TE/L PRE-MIX UNDERCOUNTER range of machines.
They allow the dispensing of:
- cold pre-mix drinks.
The drinks are cooled by a cooling unit within the machine. The drinks are carried - via thermally insulated
plastic tubes - to the dispensing tower. The insulating tube (known as the “python”) and the dispensing tower
are not included with the machine.
"Pre-mix drinks" means drinks that are ready for consumption, without needing any further additions or
mixing.
Beer, soft drinks and wine are all typical pre-mix drinks.
