SAFETY REGULATIONS
NEVER ALLOW WATER TO COME INTO CONTACT WITH ANY OF THE ELECTRICAL PARTS OF
DRNX: THERE IS A DANGER OF CREATING A SHORT CIRCUIT.
INTENDED USE
DRNX is intended to be used in cafes, restaurants, and pantries. It dispenses liquid from any non-pressurized
container by drawing liquid, infusing it with atmospheric nitrogen and chilling it to 2°C. Do not liquids that are
above room temperature or that are unfiltered. It must only be operated by a trained person. The appliance is
not to be used by persons (including children) with reduced physical, mental or sensory abilities or with scarce
experience and/or expertise, unless they are supervised by a person responsible for their safety, or they are
instructed by this person on how to properly use DRNX.
POWER SUPPLY
DRNX must be connected to the power supply in accordance with its specifications. Only connect it with the
specified supply voltage.
POWER CORD
Never use DRNX if the power cord is defective. Report any defects in the cord and/or plug to the service
provider immediately. Do not pass the power cord around corners, over sharp edges or over hot objects and keep
it away from oil. Do not use the power cord to carry or pull it. Do not pull out the plug by the power cord nor
touch it with wet hands. Do not let the power cord hang freely from tables or shelves.
FOR THE SAFETY OF OTHERS
Ensure that children cannot play with DRNX and/or the packaging materials. Observe the warning and safety
instructions on the electrical components and in this manual. Improper use of DRNX such as opening it during
operation, incorrectly operating it, or not following standard guidelines for operating electrical equipment may
lead to injury.
FIRE SAFETY PRECAUTIONS
In case of fire, use carbon dioxide (CO2) extinguishers. Do not use water or dry powder extinguishers.
SUITABLE LOCATION FOR OPERATION AND MAINTENANCE
DRNX should be installed in accordance with the safety regulations in force at the time of installation. Operate
it in an environment between 13°C and 32°C. Make sure it is a dust-free environment. Avoid placing open flames
and/or incandescent objects near it to avoid melting or other damage to the dispenser housing. If the dispenser
has been exposed to such conditions, alert the service provider who will carry out a safety check.
STORING DRNX
If DRNX is to remain inactive for a long time, turn it o and unplug it. Store it in a dry place, out of reach of
children. Make sure the storage area is between 13°C and 40°C. Keep it protected from dust and dirt.

GENERAL INFORMATION
REPAIRS / MAINTENANCE
In case of failure, problems or a suspected fault resulting from a fall, immediately remove the plug from the
power socket and alert the service provider or specialized technician. Never attempt to operate it if it is faulty.
Please report any fault to your service provider. Only the service provider and/or technician may carry out
servicing operations and repairs on DRNX, unless otherwise informed. Any repair of the dispenser must be done
only when it is switched o and it is ascertained that there is no electric current. All spare parts must be obtained
from your service provider. Follow the service and maintenance instructions in this operation manual.
USE
DRNX pulls any filtered liquid from an unpressurized container. It chills the liquid to 2°C and infuses it with
atmospheric nitrogen.
VISCOSITY OF LIQUID
Ensure that your beverage has been filtered in order not to clog the pre-filter or if that has been bypassed, not
to clog the machine. Thick liquids risk slowing down the liquid pump inside. DRNX comes with a pre-filter that is
already fitted onto the beverage tube. If the pre-filter is not attached, you can risk damaging components inside.
BEVERAGE CONTAINER
Any non-pressurized container can be used depending on what is required. We recommend using the designated
BROOD container (sold separately).
