Environmental Requirements
This model is intended for indoor/interior applications only
and is not to be used in installations that are open/exposed
to natural elements.
This unit is designed to operate between 50°F (10°C) and
90°F (32°C). Higher ambient temperatures may reduce the
unit’s ability to reach low temperatures and/or reduce ice
production on applicable models.
For best performance, keep the unit out of direct sunlight
and away from heat generating equipment.
In climates where high humidity and dew points are
present, condensation may appear on outside surfaces.
This is considered normal. The condensation will evaporate
when the humidity drops.

! WARNING
SHOCK HAZARD — Electrical Grounding
Required. Never attempt to repair or perform
maintenance on the unit until the electricity has
been disconnected.
Never remove the round grounding prong from
the plug and never use a two-prong grounding
adapter.
Altering, cutting or removing power cord,
removing power plug, or direct wiring can cause
serious injury, fire, loss of property and/or life,
and will void the warranty.
Never use an extension cord to connect power to
the unit.
Always keep your working area dry.
NOTICE
Electrical installation must observe all state and
local codes. This unit requires connection to a
grounded (three-prong), polarized receptacle
that has been placed by a qualified electrician.
The unit requires a grounded and polarized 115 VAC,
60 Hz, 15A power supply (normal household current). An
individual, properly grounded branch circuit or circuit
breaker is recommended. A GFCI (ground fault circuit
interrupter) is usually not required for fixed location
appliances and is not recommended for your unit because
it could be prone to nuisance tripping. However, be sure
to consult your local codes.
See CUTOUT & PRODUCT DIMENSIONS for recommended
receptacle location.

Dispensing Coffee
The left tap delivers still cold brew which is refreshing and less acidic than hot coffee. The right tap delivers nitrogen-infused
coffee which is the ultimate cold brew experience. Thousands of micro-nitrogen bubbles are infused as the coffee is dispensed. This creates a naturally slightly sweet taste and thicker and smoother texture.
Troubleshooting
ISSUE
CAUSE
No/reduced liquid flow
through faucet(s).
The strainer inside of the filter bowl assembly
is clogged or beginning to clog.
See cleaning section
Nitrogen source is empty or turned off.
If applicable, assure that the nitrogen tank is not empty and
that the nitrogen shutoff switch is in the on position (in-line with
the tube). Also assure that the knob on top of the tank is turned
all the way counterclockwise. If the tank is empty, replace it
with a full one.
Liquid and/or nitrogen ball lock disconnects
are not fully connected to product tank.
Attach the liquid/nitrogen ball lock disconnects to the product
tank. If they already appear to be connected, disconnect/
reconnect them.
The nose cone of the faucet is clogged.
Detach the nose cone assembly from the stout faucet by turning
it counterclockwise. Remove the stainless steel restrictor disc
and inspect the small holes to assure that none of them are
clogged.
The system is dirty and requires a thorough
line cleaning/sanitizing procedure.
Follow the line cleaning procedure above to remove buildup and
restore full flow.
The secondary regulator is set to a pressure
that is either too high or low.
If there is less/more nitro effect than desired, use the black
knob on the secondary regulator assembly to make a change.
To adjust the secondary regulator, pull the black knob out until
you feel a slight click. This is the adjustment mode. To increase
the level of nitro, turn this knob clockwise. To decrease the level
of nitro, turn the knob counterclockwise. Continue adjusting and
pouring until the level of nitro meets your requirements. Once
you have found your desired level of nitrogenation, push the
black knob back in to lock it in place.

USER GUIDE
DEFROSTING
Under normal conditions this unit does not require manual
defrosting. Minor frost on the rear wall or visible through
the evaporator plate vents is normal and will melt during
each cycle.
If there is excessive build-up of 1/4” (6 mm) or more,
manually defrost the unit.
Ensure the door is closing and sealing properly.
High ambient temperature and excessive humidity can also
produce frost.
! CAUTION
DO NOT use an ice pick or other sharp instrument
to help speed up defrosting. These instruments
can puncture the inner lining or damage the
cooling unit. DO NOT use any type of heater to
defrost. Using a heater to speed up defrosting can
cause personal injury and damage to the inner
lining.
NOTICE
The drain pan was not designed to capture the
water created when manually defrosting. To
prevent water from overflowing the drain pan
and possibly damaging water sensitive flooring,
the unit must be removed from cabinetry.
To defrost:
1.
Disconnect power to the unit.
2.
Remove all products from the interior
3.
Prop the door in an open position (2 in. [50 mm]
minimum).
4.
Allow the frost to melt naturally.
5.
After the frost melts completely, clean the interior and
all removed components. (See INTERIOR CLEANING).

CHECKING PRODUCT TEMPERATURE
Causes which affect the internal temperatures of
the cabinet include:
•
Temperature setting.
•
Ambient temperature where installed.
•
Installation in direct sunlight or near a heat source.
•
The number of door openings and the time the door is
open.
To check the actual product temperature in the
unit:
•
The time the internal light is illuminated. (This mainly
affects product on the top rack or shelf.)
1.
Partially fill a plastic (nonbreakable) bottle with water.
•
Obstruction of front grille or condenser.
2.
Insert an accurate thermometer.
3.
Tighten the bottle cap securely.
4.
Place the bottle in the desired area for 24 hours.
5.
Avoid opening the unit during the testing period.
6.
After 24 hours, check the temperature of the water.
If required, adjust the temperature control in a small
increment (see CONTROL OPERATION).

Product Liability
Field service technicians are authorized to make an initial
assessment in the event of reported damages. If there are
any questions about the process involved, the technician
should call the manufacturer for further explanation.
While inspecting for defects or installation issues, photos
should be taken to document any damages or issues found.
During the assessment, if the service technician is able to
find the source of the damage and it can be resolved by
replacement of a part, the servicer is authorized to replace
the part in question. The part that caused the damage
must be returned to the manufacturer in its entirety. The
part must be clearly labeled with the serial number of the
unit it was removed from, the date, and the servicer who
removed the part.
If the service technician determines the damage is the
result of installation issues (water connection/drain, etc.),
the consumer would be notified and the issues shall be
resolved at the direction of the consumer.
If damage is evident and the service technician is unable
to find the source, the manufacturer must be contacted at
