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

• 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.
