Ice
The Nugget Ice Machine produces cylindrical bits of compressed ice
approximately 3/4″ x 1/2″. Ice is produced until the machine senses the bin is
full. As ice slowly melts in the bin, the level of ice drops and ice
production resumes. This ensures a constant supply of fresh ice is always
available. The factory default ice setting is 0, which produces a firm and
compact ice nugget. U-Line’s exclusive U-ChooseTM ice adjustability feature
allows you five levels of adjustment from 0 to -5. At -5 the ice is soft and
chewable. To adjust the ice density: 1. Hold for 5 seconds – display will

Only a clean, dry leak free system should be charged with R-600a.
R-600A Specifications
R-600A SPECIFICATIONS/LABELING R-600a equipped products are labeled (both the
unit and the compressor). R-600a is colorless and odorless. R-600a is
considered non-toxic, but is flammable when mixed with air. Do not remove or
alter any R-600a labeling on the product. Use only a refrigerant grade R-600a
from a properly labeled container. RECOVERING/RECLAIMING R-600A (R-600a has
been exempted from recovery/reclaiming requirements by the US EPA)
Recovery/Reclaiming equipment must be approved for use with R-600a. Ensure the
evaporator is at room temperature prior to recovery/reclaiming R-600a. Use a
common piercing pliers or piercing valve to remove R-600a from the compressor
process tube. (Note: Piercing devices must not be left on the system and must
be replaced with a Schrader type valve.)
37
USER GUIDE
Evacuate/reclaim via the piecing pliers to ensure the system is empty of
R-600a before any system work is performed.
The recovery cylinder must be evacuated (no air inside) prior to accepting
R-600a. The recovery cylinder must not be filled more than 45% safe fill level
and refrigerants must not be mixed. The recovery cylinder must be clearly
marked with R600a and Flammable Warning labels. Ensure proper ventilation
during recovery/reclaiming of R600a. Start vacuum pump/recovery pump prior to
piercing the compressor process tube. Follow recovery/reclaim OEM instructions
for the specific equipment used. SYSTEM REPAIR Ensure no residual R-600a
refrigerant is left within the system prior to repair (simple venting is not
sufficient). Evacuate and charge with dry nitrogen for leak checks. Repair
leaks or replace system parts as required.
When re-brazing, the system must be purged with dry nitrogen and at least one
access point open to the atmosphere. When re-brazing, proper ventilation is
required along with constant monitoring for the presence of R600a refrigerant.
The filter dryer must be replaced any time the sealed system is serviced. No
system should be open to the atmosphere for longer than 15 minutes to avoid
moisture migration into the system components. LEAK DETECTION After removal of
the R-600a, the unit can be charged with dry nitrogen or helium. Electronic
leak detection or soap solution can be used to check for nitrogen/helium
leaks.
Never use a halide torch or lighted match to check the system for leaks at any
time. The high side of the refrigeration system (compressor discharge to
outlet of drier) must be leak tested with the compressor running.
R-600A Specifications
38
USER GUIDE
The low side of the refrigeration system (evaporator, compressor and suction
line) must be leak tested with the compressor off (equalized pressure).
RECHARGING No air is ever to be allowed inside the refrigeration system
(R-600a refrigerant or dry nitrogen only).
Never use a torch on a fully charged refrigeration system.
Install a Schrader Type access port on the compressor process stub.
Proper ventilation during service is required.
Never apply a torch to a charged R-600a refrigeration system.
Use OEM replacement service parts and do not alter the construction of the
unit.
Evacuate the system to 100 microns prior to charging.
Weigh in the R-600a charge using a refrigerant scale. (run compressor an extra
two minutes to clear the charging hoses).
Seal the Schrader Type access port, a proper cap and seal must be used to
close the system.
SUMMARY Safely handling R-600a requires proper procedures and training.
R-600a approved service tools must be used.
R-600a labeling must not be removed or altered.

Relay & DC Outputs
One of the primary functions of the main control is to operate the multiple
relay and DC outputs during each cycle. Verify proper operation of these
relays using the following procedure.
1. Enter “Component Toggle” through the service menu.
NOTICE
Frequently toggling the compressor relay could force the compressor into
overload. The compressor will automatically deactivate during an overload and
will remain deactivated until the overload switch cools. This could take some
time. It is important to allow the compressor at least 5 minutes off time
between relay cycles.
2. Toggle the desired relay. (Refer to Control Operation for complete relay
list) Its related component should activate / deactivate with the switching of
the relay. If it does not, test component
Other Suspected Main Control Faults
If other components have been ruled out as being faulty, but the unit
continues to have operating issues, it is most likely due to a configuration
error. Some configuration errors can be cleared by restoring the unit to its
factory default setting. Factory defaults may be restored through the service
menu. If that does not work, check that the board is programmed to the correct
model in the service menu.
! CAUTION
Precautions must be taken while working with live electrical equipment. Be
sure to follow proper safety procedures while performing tests on live
systems.
PLUNGER SWITCH A plunger switch is used to monitor door state. When the door
is closed it comes into contact with the plunger which closes a circuit which
turns the light and display off. When the door is open the plunger moves
outward and opens the circuit. If the door is left open for longer than 5
minutes the switch will trigger an error code and set an audible warning.
ERROR CODES
All errors are logged in memory. Only door error is displayed on the display and has an audible signal.

E11: Sensor in base near fan detecting water
This sensor is designed to detect water escaping the product due to any type
of malfunction inside the machine. Once activated, the only way to reset this
error is to completely dry the two probes and cycle power to the machine via
the rocker switch or power cord. Once power is cycled, it will take 20 minutes
to reactivate the error code. Only the drain pump will retain power and be
able to activate under this condition.
Inspect the entire base area in front and behind the sensors.
b. If TDS is acceptable, unit must be cleaned and any leakage addressed with a
seal kit. (U-Line service part # 80-55371-13)
*SEE “WATER HOOKUP” SECTION FOR SPECIFIC INFORMATION REGARDING TDS LEVELS

1. Power cycle to reset error 2. Check sensors to ensure there is a gap
between
sensors and pan as shown. 3. If error persists, check wiring to sensors for a
short.

1. If the unit is equipped with a drainage pump, inspect it for leaks – check
connections.
2. Remove pump and check all connections on water valves, water supply, and
drain.
3. Check bolt on water reservoir. If loose, it may leak during a clean cycle
when reservoir is filled to the top. Torque Spec. is 16 in-lbs.
4. Check areas around ice maker auger on both ends. If any leakage is
evident, it is likely poor water quality and/or failure to clean is the cause.
a. Check TDS (see WATER HOOK UP section) – if outside tolerance, please report
to factory and advise homeowner that repairs cannot be made to unit until
water quality issue is resolved. Filters available at u-line.com are able to
treat TDS up to 600.*

Gap
E12: Float switch in reservoir not rising
This error is designed to ensure sufficient water exists to produce ice, thus
preventing permanent damage to the module. In order for this error to occur,
the ice-making sequence must initiate two tries to fill the reservoir. This
may take an hour or more to generate the error code.
Steps to check and correct – remember it is necessary to power cycle after
making the corrections. 1. Check incoming water supply to ensure it is turned
on
and has sufficient pressure. 2. Verify water filter (if applicable) is in
place and has
been replaced on schedule. 3. If unit is a 1 Class product, enter service mode
and
activate relay 4 to determine if unit fills with water. a. If it does not
fill, check water valve for power
during sequence. · If there is power, check valve resistance to
determine if coil is shorted. · Check valve to ensure it is not blocked with
debris.
45
USER GUIDE
b. If unit fills, the float switch is malfunctioning and needs to be replaced
(part # 80-55538-00).
4. If unit is 3 Class product, enter service mode and activate relays 1 and 4
to determine if unit fills with water. a. If it does not fill, check water
valve for power during sequence. · If there is power, check valve resistance
to determine if coil is shorted. · Check valve to ensure it is not blocked
with debris. b. If unit fills, the float switch is malfunctioning and needs to
be replaced (part # 80-55538-00).
E13: Float switch in reservoir not dropping quickly enough
This error is designed to detect insufficient ice product due to overheating
or poor water quality. Failure to address this error can cause permanent
damage not covered under warranty. The user may notice deteriorating ice
quality prior to the error.
Steps to check and correct – remember it is necessary to power cycle after
making the corrections.
1. Ice is slushy and user noticed deterioration in quality prior to the
error. a. Check condenser and toe kick. Fan must be operating and clear of
debris. b. Check TDS level. (see WATER HOOK UP section) High levels of TDS
will result in this error.
2. In more severe conditions, not covered above, the unit may run up to an
hour prior to generating this error, resulting in very slushy ice or no ice
production at all.* a. High TDS. High TDS restricts ability to produce ice and
causes excessive buildup of minerals on the ice-making mechanism. A single
cleaning may not resolve this condition. b. General cleaning has not been
performed. A single cleaning may not resolve this condition. c. If customer
has unit connected to a water softener, have them consult a plumber to
disconnect from the softener.
Troubleshooting Extended
*SEE “WATER HOOKUP” SECTION FOR SPECIFIC INFORMATION REGARDING TDS LEVELS d. Check compressor operation. · If unit is not cooling or compressor is not operating, diagnose and fix system problem. · If unit is cooling, check auger for rotation. If not rotating, check the motor and electrical connections to auger.
3. If the ice has been solid and appears solid after a power cycle check it
is possible the float switch is not operating properly and should be replaced.
P1: Drain related error
This error is designed to prevent water related issues due to a failure of the
unit to drain water. In most cases this error is not related to the unit and
related to improper installation or restriction of the drain line. 1. If the
unit does not have a drain pump this error is
generated by a missing jumper on the power harness. Inspect and install
jumper. 2. If the unit does have a drain pump. a. Check the installation to
ensure the drain line is
not restricted leaving the unit. b. Inspect the drain pump to determine if the
motor
is operating. A slight noise should be heard if the pump is full of water.
Ice Level Issues If there is a complaint regarding the unit filling too full
with ice. 1. Check the thermistor to ensure it is installed properly
and any holes through the rear of cabinet are completely sealed with sealing
compound. Warm air that can make its way to the thermistor will give improper
readings and cause the bin to overfill. 2. The bin thermistor offset may be
changed via service mode option #5. Be careful to adjust in small increments
to suit customer preferences.

Thermistor
Thermistors are used for various temperature readings. Thermistors provide
reliable temperature readings using a resistance which varies based on
surrounding temperatures. If a faulty thermistor is suspected, it may be
tested using an accurate ohmmeter.
Thermistor connections must be kept clean. A thermistor connection that has
become corroded can cause resistance values from the thermistor to change as
they pass through a dirty connection to the board.
It is for that reason that we apply dielectric grease to all of our thermistor
connections. Dielectric grease will help to keep thermistor connections clean
and dry.
If you change a thermistor in the unit, please re-apply dielectric grease to
the connection. If you encounter a dirty thermistor connection, you should
replace the thermistor and the thermistor harness.
This unit has one thermistor located along the right hand sidewall of the ice
bin. It is used to maintain the ice level in the bin.
