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.

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).

Wait 2 hours before trying to pour again.
If DRNX is used without a pre-filter
in the beverage tube, coee particles
may get into the pump and damage
or block valves. Liquid may not be
drawn in anymore.
The machine and the pump must be flushed with
tap water.
1. Unscrew the tap nozzle.
2. Connect the beverage tube to the inlet
connector.
3. Disconnect the pre-filter.
4. Switch the machine o.

FAQ
Q. I JUST RECEIVED MY DRNX, HOW DO I SET IT UP?
A. Please follow the instruction manual that comes with DRNX. It is easy to set up!
Q. WHERE DO I PUT MY COLD BREW COFFEE OR TEA?
A. DRNX can pull cold brew from any non-pressurized container. DRNX comes with a beverage tube that clips into the
dispenser from underneath. The other end is loose so that an operator can drop it into any container. Alternatively, an
operator can attach a keg coupler, bag-in-box adaptor, or an elbow fitting to the other end of the beverage tube in order to
connect it to a keg, bag in-box, or BROOD container respectively. Please watch our instructional video on our website.
Q. I AM NOT GETTING ENOUGH CREMA, WHAT SHOULD I DO?
A. Firstly, pull the tap fully downward (90°) to trigger nitrogen infusion. Pulling it only a little bit will yield still cold brew
only. Secondly, rotate the infusion dial towards the 12 o’clock position. Thirdly, the pre-filter might be clogged and in need
of cleaning. Check our troubleshooting section.
Q. I AM GETTING LARGE BUBBLES IN MY NITRO COLD BREW, WHAT SHOULD I DO?
A. Make sure all the tubes are pushed in firmly and there is no air seepage. Observe if there are any air bubbles flowing
through the beverage tube. Air that seeps into the tubes will ultimately come out at the tap in the form of air bubbles.
This will also happen if your beverage tube is sucking in air from a loose connection. The quality of the cold brew also has a
marked eect on the size of the bubbles in the final head of the drink. The more filtered the cold brew, the smoother the
surface of the head.
Q. MY BEVERAGE IS NOT COLD ENOUGH, HOW DO I MAKE IT COLDER?
A. Follow the instructions in section “Temperature Control” on page 6 to decrease the temperature.
Q. DRNX IS NOT POURING COLD BREW, WHAT SHOULD I DO?
A. There are several reasons why this may happen. All of them are easily remedied. Please follow our troubleshooting guide
in this instruction manual.
Q. WHEN I POUR MANY GLASSES OF NITRO COLD BREW CONTINUOUSLY, THE FOURTH ONE IS
SOMETIMES SLIGHTLY LESS CHILLED THAN THE FIRST ONE. WHY IS THAT?
A. We recommend pouring for 45 seconds which is about 1 litre (32oz.) and then pausing for a few moments until the
exhaust fan switches o. This means the cold brew inside the fridge has been chilled to your desired temperature.
Q. DRNX HAS A SOUND THAT COMES AND GOES, WHY?
A. This is the sound of the exhaust fan. When this sound is heard it means that the fridge is cooling down to the pre-set
temperature. When the sound stops this means that the compressor has also stopped as the desired temperature has
been reached.
Q. I HAVE THE FRIDGE SET AT THE COLDEST POSSIBLE TEMPERATURE, BUT THE BEVERAGE IS NOT
COLD ENOUGH, WHY IS THIS?
A. The variance between the cold brew in your container and at the tap is 22°C. This means if your cold brew is 24°C (room
temperature) then the nitro cold brew at the tap will be 2°C. Never use cold brew or any other liquid that is warmer than
room temperature.
Q. DO I NEED TO KEEP A GAP AROUND THE VENTS ON THE TOP OF DRNX?
A. Yes, never cover the exhaust located on top of the machine. If covered, it may damage the compressor.
