NOTE: Only trained and certified technicians should make adjustments to this system.
NOTE: Any time an adjustment is made to brix or level of N2 infusion, 12 OZ of liquid must
be poured from the affected faucet(s) for the adjustment to take full effect. At that point, a
full serving can be poured and tested.
ADJUSTING LEVEL OF N2 INFUSION: GENERAL INFORMATION
• N2 Infusion set to specification by making adjustments to on board N2 regulator pressure.
• See N2 regulator pressure gauge to determine pressure of N2 being applied to the infuser.
• Adjust using a flathead screwdriver: turn clockwise to increase pressure setting or
counterclockwise to decrease pressure setting.
• N2 regulator pressure should not fluctuate once set.
NOTE: The N2 regulator adjustment screw features a nut that can be tightened to lock in a
pressure setting. Ensure this nut is loose before attempting to make any adjustments.
MAKING ADJUSTMENTS
16 | JOETAP® BARISTA INSTALLATION, USE & MAINTENANCE GUIDE 855-4JOETAP / (866) 327-4159 / MICROMATIC.COM
PROCEDURE
• Increase Level of N2 infusion (thicker head and more dramatic cascading effect).
– Turn the N2 regulator adjustment screw clockwise.
– Hold the gas in button for a full second.
• Decrease Level of N2 infusion (thinner head and less dramatic cascading effect).
– Turn the N2 regulator adjustment screw counterclockwise.
– Hold the gas out button for a full second.
– If the N2 Generator turns ON, wait for it to build pressure and automatically turn OFF.
– Hold the gas in button for a full second.
NOTE: The N2 regulator adjustment screw is sensitive and may require very small turns/
adjustments to achieve desired N2 infusion specification.
ADJUSTING BRIX WITH VOLTAGE: GENERAL INFORMATION
• The voltage regulator controls the voltage that is supplied to the peristaltic pump. Voltage
supplied to the pump determines how fast the pump motor spins (RPM) and how much
liquid can be displaced (flow rate) for a given tubing diameter and gearbox.
• The voltage regulator should be set no lower than 12V.
– If the proper flow rate cannot be achieved by adjusting voltage within 12-22V, a tubing
change or gearbox change may be necessary.
– If flow rate is too high at 12V, a smaller diameter tube and/or lower RPM gearbox must
be used.
– If flow rate is too low at 22V, a larger diameter tube and/or higher RPM gearbox must
be used.
NOTE: see Peristaltic Pump Package Guide (section 6) to determine optimal tubing/gearbox
package.
PROCEDURE
• Using a flathead screwdriver, gently pry away the clear plastic cover covering the
voltage regulator.
• Turn the water pump button OFF and the product pump button ON.
• Open either of the faucets for a full second and close it.
• Adjust the voltage regulator to the desired voltage.
NOTICE
Do not leave the product
pump button on while the
water pump button is off for
extended periods of time,
as this will cause excessive
wear on the equipment and
could result in pre-mature
product pump maintenance

• To adjust the voltage regulator, press
the set button until a digit that needs
adjusted is blinking.
• Once a digit that needs adjusted is
blinking, use the +/– buttons on the
regulator to increase or decrease the
blinking digit’s value.
• Press the set button to save the updated
digit and voltage.
• If more than one digit needs adjusted to
achieve the new voltage setting, adjust
them accordingly.
ADJUSTING STILL WATER FLOW CONTROL VALVE: GENERAL INFORMATION
• Still water flow control allows the installer to adjust and set the water flow rate for the still
faucet independently of the nitro faucet water flow rate.
– Turning the flow control knob clockwise reduces water flow rate.
• Reducing water flow rate will make the finished product stronger (higher brix).
– Turning the flow control knob counterclockwise increases water flow rate.
• Increasing water flow rate will make the finished product weaker (lower brix).
NOTE: Adjustments to still water flow control should not occur until nitro faucet has been
fully calibrated.
NOTE: As a point of reference, the nitro faucet has a constant water flow rate of about 1 OZ/
SEC. To achieve a still drink that is higher in brix and stronger in taste than the equivalent
nitro drink, the flow rate must be adjusted to be less than 1 OZ/SEC. To achieve a still drink
that is lower in brix and weaker in taste than the equivalent nitro drink, the flow rate must be
adjusted to be greater than 1 OZ/SEC.
NOTE: It is helpful to begin with the flow rate knob closed (turned all the way clockwise)
and slowly open (turn counterclockwise) until desired still water flow rate is achieved. To
conserve on Bag-in-Box product, it is recommended that still water flow rate be adjusted
with the product pump turned off. Once flow rate is adjusted to approximately 1 OZ/SEC,
the product pump button can be turned on. At that point, small adjustments and brix
measurements can be made until the still product meets specification.
PROCEDURE
• Using a flathead screwdriver, remove the black plastic cap covering the still water flow
control knob.
• Adjust still water faucet flow rate by turning the adjustment screw/knob clockwise or
counterclockwise.

PROCEDURE (CONTINUED)
• Test the flow rate adjustment and continue adjusting/testing until the desired water flow
rate and still faucet brix reading are achieved.
• Reinstall the black plastic cap that covered the still water flow rate adjustment.
ADJUSTING PRESSURE SWITCH
NOTE: Always check for debris in nose cone of pulsing faucet before determining pressure
switch needs adjusted.
• If the flow is pulsing with the faucet wide open, the pressure switch corresponding to that
faucet may need adjusted.
– Remove the lid, nitrogen generator chassis & insulation board to access pressure
switch in question.
• Using a .05" Hex Key, turn the adjustment screw clockwise.
• If pumps can be heard running after a faucet is closed and fresh pours begin with an
inconsistent flashing of water and then finished product, the pressure switch for that
faucet likely needs adjusted.
– Remove the lid, nitrogen generator chassis, & insulation board to access pressure
switch in question.
• Using a .05" Hex Key, turn the adjustment screw counterclockwise.
• Continue making adjustments and testing until both faucets are consistently pouring
to specification.
NOTE: Pressure switch adjustments more common with less concentrated Bag-in-Box
products and higher N2 infusion settings.
MEASURING BRIX USING A DIGITAL HANDHELD REFRACTOMETER
• Ensure the refractometer is calibrated and the prism is clean.
– Fill the sample stage with distilled water and press the zero button.
• Pour a full serving.
NOTE: If poured from the nitro faucet, allow it to finish cascading. N2 in the sample can
affect accuracy of brix reading.
• Using a pipette or straw, take a sample from the full serving and drip it onto the sample
stage until the product completely covers all of the metal.
• Allow the sample stage to conform to the temperature of the prism to achieve
accurate measurements.
NOTE: This can take up to 90 seconds. Taking a measurement before allowing temperature
equalization can result in inaccurate measurements.

• Press the start button to test the sample.
• Record the brix reading.
• Press the start button to test the sample again.
NOTE: If the readings differ by more than .1, press the start button once more and test/
record the reading. Continue until two of the same readings are recorded. This reading
should be interpreted as the current brix for the faucet being tested.
PERISTALTIC PUMP PACKAGE GUIDE
To determine the best peristaltic pump package, follow the instructions below:
• Determine the water to product dilution ratio (concentration) of the Bag-in-Box product.
• Determine the Bag-in-Box product flow rate required.
– This is accomplished by dividing the nitro water flow rate by the dilution ratio.
– Example: for a 5:1 ratio, the necessary product flow rate is:
(1775 ML/MIN / 5) = 355 ML/MIN
– Choose a pump package that is close to but exceeds the calculated product flow rate.
NOTE: See Peristaltic Pump Flow Rate chart below.
– In the case of a 5:1 ratio product, there are two ideal packages.
• 172 RPM gearbox with a ¼" tube – 600 ML/MIN
• 282 RPM gearbox with a 3/16" tube – 580 ML/MIN
– If there is more than one ideal pump package, choose one that requires less time/
labor for setup.
– Typically it is easier and less time consuming to change a tube than it is to change
a gearbox.
– Once the tube and gearbox package are selected, the supplied voltage to the peristaltic
pump and the still water flow control valve are used to dial in brix of finished product.
PERISTALTIC PUMP FLOW RATE CHART
NOTE: Flow rates advertised in this chart are nominal and may vary.
NOTE: Bag-in-Box product flow rates will likely be less than advertised in this chart.

GENERAL OPERATION
• Under normal circumstances, both green switches on the face of the chiller, the water
pump button, and the product pump button should be ON.
• Use only one faucet at a time. If both faucets are opened at the same time, the nitrogen
faucet will starve for water and begin sputtering. If this occurs, close both faucets and
open one at a time until the flow is restored and they are pouring to specification.
• When operating the faucets, ensure that you pull the handle all the way down so that
it is at 90 degrees (perpendicular to the flow of coffee from the faucet and parallel to
the countertop).
• To achieve product with a rich tight head, tilt the glass slightly and pour the product down
the side of the cup. This method will prevent splattering and turbulence in the cup.
• Natural products settle/separate over time. Shake the Bag-in-Box thoroughly prior to
connecting it.
CHANGING AND ATTACHING A BAG-IN-BOX
• Acquire Bag-in-Box product and remove white cap from the fitting.
• If applicable, disconnect empty Bag-in-Box and dispose of it appropriately.
• Rinse connector using a small cup of warm water.
• Attach Bag-in-Box connector to fitting on the full Bag-in-Box.
• Place the full Bag-in-Box inside with fitting facing downwards.
• Open each faucet one at a time until flow transitions from water to finished product.
• Fill the sample stage with distilled water and press the zero button.
• Pour a full serving.
NOTE: If the faucet has been open for at least 30 seconds, and hasn’t transitioned to finished
product, ensure the product pump button is on (illuminated amber ring) and check the Bag-
in-Box connection to make sure the fitting is attached properly. If the product pump button
is ON, the Bag-in-Box is attached properly, and the system won’t dispense finished product
after 30 more seconds of pouring water, attempt the following Bag-in-Box priming process.
• Turn water pump button OFF.
• Open either faucet until undiluted Bag-in-Box product is being dispensed.
• Turn the water pump button ON.
• Open nitro faucet, dispense 6 OZ of liquid, and dispose of it.
• Open still faucet, dispense 6 OZ of liquid and dispose of it.
