Intended Usage
The Brewista® Cold Pro Nitro™ Dispenser is a ready-to-use dispenser to tap nitrogenized
and cooled beverages in parcular cold-brew coee. Such systems are mainly used for
professional customers in hotels, restaurants and bars. The nitrogen eect is created
through ltered compressed air which contains 78% nitrogen. The device is only approved
for this applicaon and is not suitable for cooling hot liquids, unltered liquids, chemicals, or
similar substances.
Operaon Instrucons
Assemble your Cold Pro™ Nitro
1) Place the device in a level, clean, and dry locaon.
2) Screw on tap components to the tap [(1), (2), and (3)] and secure handle (1)
with locknut.
3) Place the drip tray (6) in front of the unit. Remove the protecve lm and
discard.
4) Turn the temperature control (5) clockwise to maximum (7 o’clock posion).
5) Put air-compressor switch (marked with PRESSURE) (16) to “O” (o).
6) Plug in the power cord (17) to a grounded outlet (refer to Addional Safeguards,
page 3).
Connect the Intake Line
1) To connect the intake line (11) to the dispenser a coupler system is used. Simply
push the male and female parts together.
2) To release the intake line, push the metal spring component.
• If the intake line is too long, reduce the length with a clean smooth cut.
• If you want to increase the cooling power of your system you can assemble
an addional cooler in your intake line and an addional lter must be used
(see next point).
3) To assemble the lter adapter:
• Make a perpendicular cut across the tubing to be connected.
• Remove any burs or sharp edges.
• Ensure the outer diameter is free of score marks.
• For so or thin-walled tubing, use a tube insert for
added strength and stability.
• Push the tube into the ng.
• Pull on the tubing to check that it is secure. Test the
system before use.
• Verify the ow is in the direcon of the arrows noted on intake lter.
• To disconnect tubing: ensure the system is depressurized, push and hold the
collet square against the ng to remove the tube.
• Note: If a lter adapter is not part of your intake line, coee grounds
or other parcles could block the jet nozzles in the device or impair the
funconality of the membrane pump and make the device unusable.
4) Make sure the intake line (11) is pushed into its the socket (15) rmly.

7
Connect your Cold Brew Container
• Note: Brewista recommends checking funconality of your system by using
water. This will also help ush out any cleaning soluon residue from the
system as well.
• Connect the intake line tubing (11) to your cold brew container. If your intake
line is connected to a keg, be sure the system can draw air or is fed with inert
gas when tapping starts and coee is dispensed.
Dispensing your Nitro Cold Brew
1) Push air-compressor switch (marked with PRESSURE) to “I” (on). The
compressor can remain switched on overnight.
2) Place a glass on the drip tray under the dispensing spigot and pull the tap
handle forward by 90°.
3) The unit now pumps the coee from the container and aer a short period of
me, cooled and nitrogenized cold brew coee ows out of the tap. You may
need to tap 1-2 glasses unl you get the desired foam level.
4) To stop dispensing, lt the tap handle upwards to a vercal posion.
Adjustable Sengs
• Temperature
The target dispensing temperature can be adjusted with the temperature
control at the front of the dispenser within a range of 21° F (12° C).
◦To make the brew colder, turn the temperature control (5) clockwise (max
posion is 7 o’clock).
◦To make the brew warmer, turn the temperature control (5) counter-
clockwise
◦Turn the cooling funcon o by turning the temperature control (5) to the
9 o’clock posion.
-Temperature range: 41° F (5° C) (+/- 1.8° F or 1° C) to 62° F (17° C).
◦The dispenser has an internal buer of 17  oz (500 ml) that is kept cold
according to the temperature control sengs. In a non-stop dispensing
situaon the cooling result depends on the owrate.
-When using the 2-hole disc (10) (ow rate of 0.6 L/min) there will be
a 12° F (7.0° C) reducon between input and output temperature.
-When using the 5-hole disc (9) (ow rate of 1.2 L/min) there will be a
6.3° F (3.5° C) reducon between input and output temperature.
• Gas Level
On the side of the
machine, remove
the white cap
marked with “GAS
CONTROL” (14).
Pull out the
grey knob
approximately
2 mm.
By default the knob
is set to 1 (with a
tolerance of +/- 0.25).
-Turn the knob
clockwise to reduce
the gas level
-Turn the knob
counter-clockwise
to increase the gas
level
-Do not turn knob
higher than 2
Push back the
grey knob to
lock posion
and replace the
white cap.

8
• Ensure that your coee was ltered with a neness of
at least 100 μm (microns). Coarser ltraon sizes lead to
clogging of the lter in the intake line or in the jet-nozzle
outlet-spout of the tap.
• Make sure the lter adapter (19) is installed in the intake
line. The dispenser comes with a DMT lter adapter
which can easily be integrated into a 3/8” intake hose.
WARNING: By not using the appropriate intake lter, the
internal dispenser pump could be damaged or destroyed
from coee parcles and will void the warranty.
Decommissioning
• Flowrate
◦The 2-hole disc (10) is installed in the dispenser by default. This provides a
owrate of 0.6 L/min.
◦A 5-hole disc (9) is included in your accessories. The owrate with the
5-disc is 1.2 L/min.
◦If you change the owrate you might have to re-adjust your desired gas
level as described above.
◦Desired temperature sengs may need to be adjusted as well if owrate
is changed.
Higher Cooling Power for High Volume Dispensing
If you need increased cooling power for peak demand situaons like high trac events, you
have the opons listed below:
• Pre-cool the coee in the refrigerator before connecng container to the dispenser.
• Use the Cold Pro Nitro™ dispenser in combinaon with a refrigerator, under counter
refrigeraon, or a cooling box. In this scenario, the coee remains cool and does not
warm up aer connecng to the dispenser.
• Place an addional cooler along the intake line of the dispenser. The coee is
passed through the addional cooler rst on its way to the dispenser.

• Before pung the dispenser out of service for an extended period of me, we
recommend cleaning the system rst.
• Aer cleaning, ush the dispenser with clean water.
• Let the dispenser suck air to empty the internal liquid buer (around 17  oz /
500 ml) is emped. Do NOT disconnect the intake line from the dispenser in order
to suck air. The coupler system has a check valve that prevents air sucon so the
internal liquid buer cannot be emped.
• Disconnect the intake line (11) and unplug the power cord (17).
• Pull tap handle (1) to release internal pressure.
• Protect the dispenser against rain, dust, and temperatures lower than 32° F (0° C) or
higher than 140° F (60° C).

Product Shelf Life
The product shelf life aer setup/connecon depends on several circumstances that are
independent from the dispenser itself. These include:
• Shelf life of product before connecon
• Connecon spout system (hygienic concept / design)
• Ambient or cooled environment before and aer connecon
• Tapping frequency
• Cleaning frequency and detergent used for cleaning
Product shelf life and the product quality are the responsibility of the operator of the
dispenser.
Downmes
• If the dispenser is not used for more than 2 days it should be ushed with fresh
water before dispensing coee again.
• If the dispenser is not used for more than 10 days, a thorough cleaning should be
performed before restarng the coee dispenser.
Cleaning Instrucons
Brewista recommends Cafeo Cold Pro Cleaner for cleaning your Cold Pro Nitro™ System
To clean your Cold Pro Nitro™ System:
1) Flush dispenser with water and then with air (emptying the lines) before
unscrewing and dismantling parts.
2) Unscrew jet-nozzle (3) and rinse it with fresh water. Use a brush if needed to
remove any parcles in the strainer (8). Reassemble tap parts [(1), (2), and
(3)].
3) Disconnect the intake lter (19) and unscrew it for inspecon. Rinse with
fresh water and use a brush if required. Replace in the intake line (11) aer
cleaning.
4) If used, disconnect your coee container spout system, dismantle, and clean
it as well.
5) Add one teaspoon of Cafeo® Cold Pro™ Cleaner to one liter of water in a
container of your choice. Let the dispenser pull the soluon through its lines
as it would with water or coee unl the soluon leaves the tap.
6) Allow to sit for one hour.
7) Flush the dispenser with water before using it to dispense product. Check
the quality of your coee before serving.

Maintenance
The Cold Pro Nitro™ System has very lile maintenance requirements.
Changing the Air Filter
• The air lter used with the Cold Pro Nitro™ System is a micro air-lter that lters
parcles up to 0.1 μm (microns) with an eciency of 99.9998%. According to DIN
EN 1822 this represents a U 15 lter class.
• We recommend changing the lter module every 2 years.
To change your system’s air lter:
1) Unplug the power cord from its wall outlet, open the tap on
your Cold Pro Nitro™ Machine, and release the pressure in
the lines. Turn the dispenser on its side.
2) Using a Phillips-head screwdriver, remove the screws from the
air lter cover and set aside in a safe place
3) Open the lter cover, pull it out, and turn it half way in a
counter-clockwise direcon so that the panel lays on your
work surface. You now have access to the air lter module.
4) Click the module out of the clamps; unscrew the side adapters
and put the new module in.
5) Click the module in the clamps and insert the cover back while
making a half turn clockwise.
6) Close the cover and replace the 3 screws.
7) Return the dispenser to its upright posion. ALWAY S place
the dispenser in an upright posion before connecng the
power cable.

Remove Dust at Condensator Grid
• Blow away any dust parcles that sele at the condensator grid on top of the
dispenser at least every 6 months or as needed. Dust parcles on this grid can
reduce the machine’s cooling eciency.
Changing O-rings and Connectors
• If a Bag-In-Box connecon system is used, O-rings or connectors may need to be
changed periodically. Frequency of changing these parts depends on the specic
system being used.
• Brewista recommends checking these connecons about once a month to ensure
proper system funcon.

Troubleshoong your Cold Pro Nitro™ System
Problem Cause Soluon
Not enough or too
much foam
The gas needle valve is not set up
properly.
Follow instrucons in the
“Changing the Gas Level” secon
on page 7. The needle valve has
a default setup of 1 mm with a
tolerance of +/- 0.25
The owrate of the coee and
the gas have to be adjusted to
coordinate together. If a change
of owrate occurs through
change of the owrate disc (9 or
10), the gas owrate has to be
re-adjusted.
Follow instrucons in the
“Changing the Gas Level” secon
on page 7. The needle valve has
a default setup of 1 mm with a
tolerance of +/- 0.25
A change in the foaming behavior
can also be aected through
a owrate reducon due to
clogging of the lter adapter (19)
or the tap jet-nozzle (3).
Check all lters or strainers
and remove any parcles in it.
Unscrew the tap nozzle (3) and
check for parcles lodged in the
strainer (8).
If there is too much foam sud-
denly, the dispenser might suck
air in via the product intake line
(11).
Check if all connecons
between the dispenser and
coee container are sealed
well. Somemes the push-in
connecon system causes air
leaks that need to be removed.
Dispensed coee
is not cold enough
No electrical power or
temperature control (5) is turned
o.
Check the dispenser’s electrical
connecon.For maximum
cooling, turn the temperature
control (5) clockwise to the 7
o’clock posion.
The temperature can be adjusted
on the temperature control (5)
on the front panel. The target
dispense temperature at max
setup is 41° F (5° C) (+/- 1.8° F
or 1° C) to 62° F (17° C). In case
of heavy tapping operaon or a
warm coee input temperature,
this temperature might not be
achieved.
If the cooling capacity of the
device is not strong enough, you
will need to increase the cooling
capacity.
Possible soluons for this are
described a the top of page 8.

12
Problem Cause Soluon
Flowrate is too
high or too low.
The perforated disc (9 or 10),
which is mounted in the jet-noz-
zle outlet-spout (3), determines
the dispenser’s owrate.
The 2 hole disc (10) provides a
owrate of 0.6 L/min.
The 5 hole disc (9) provides a
owrate of 1.2 L/min.
Put the suitable disc into the
tap nozzle (3). Be aware that a
faster owrate lowers the cooling
temperature of your beverage
during high dispensing rates.
The dispenser
does not dispense
coee
Filter adapter (19) in the intake
line is clogged.
Check to see if the lter strainers
are clogged.
Strainer (8) of the jet-nozzle’s
outlet spout (3) is clogged.
Check if the jet-nozzle’s strainer
(8) is clogged.
Air compressor is turned o or
has no electrical power.
Check the air-compressor switch
(16) at the side of the dispenser
to ensure it is turned on and if
the dispenser has power.
The coupler adapter of the intake
line is not pushed properly into
the dispenser socket (15).
Push intake line adapter properly
into dispenser socket (15).
Coee is frozen. (To achieve the
41° F / 5°C dispensing beverage
temperature, the dispenser itself
cools down a bit lower. Occasion-
ally this process overcools the
liquid and the coee can freeze.)
Set the temperature control (5)
to the 5 o’clock posion, wait
for about 20 minutes, and try
dispensing again.
If the gas level to be put into the
coee is set too high, the gas
ow overpowers the liquid ow.
In this case no coee comes out
of the tap.
Follow instrucons in the
“Changing the Gas Level” secon
on page 7. The needle valve has
a default setup of 1 mm with a
tolerance of +/- 0.25

13
Problem Cause Soluon
The dispenser
does not dispense
coee (Connued)
If the dispenser was used
without a lter adapter (19)in the
intake line (11), coee parcles
can get into the pump and
damage or block valve parts. This
could lead to a lack of sucon
and may void the warranty.
In such a situaon, the dispenser
and the pump must be ushed
with tap water.
1) Screw o the tap jet-nozzle
spout (3).
2) Connect the intake line (11)
to a water tap that provides
water with 2-4 bar.
3) Put the air-compressor
switch (16) in the
“I” (on) posion
4) Turn on the water supply.
5) Open the dispenser tap
(without the jet-nozzle
spout) and ush it with the
pressurized water from the
tap.
6) Open and close the
dispenser tap (1 and 2) in
intervals to ush out all
parcles from the pump.
