WATER SUPPLY
Observe and follow all local building codes when installing
this appliance.
This ice machine must be connected to a potable cold
water supply line. delivering water pressure between a
minimum of 20 psi and a maximum of 120 psi.
Use 1⁄4” copper tubing for your water supply which is
available at any local hardware or plumbing supply store.
Route the 1⁄4” copper tubing to suit your installation being
sure not to kink the tubing. Purchase enough copper
tubing length to allow a coil to be formed behind the unit
for a “service loop” which will allow the appliance to be
pulled out from the installation for servicing or cleaning.
(See Figure 11). Connect the copper tubing to the “top
side” of a cold water pipe to prevent the ice-maker from
plugging with sediment.
A shuto valve is recommended on the water supply line
to ease servicing the appliance. NOTE: A SELF-PIERCING
TYPE VALVE IS NOT RECOMMENDED as they are prone
to clogging with sediment which will create pressure drop
reducing the water supply to the unit.
Connect the copper tubing water supply to the water valve
inlet with a 1⁄4” compression nut tting.
IMPORTANT: Secure the water supply line to the back of
the cabinet with the screw and strain relief clamp provided
in the corner of the back panel.
Make certain all connections are watertight after
installation. Form the tubing so that it will not vibrate
against the cabinet body or kink when your appliance is
moved in and out of position.
This ice machine is designed to make clear ice from the
majority of water sources on a daily basis. If your results
are unsatisfactory, your water may need to be ltered or
treated. A water specialist can recommend proper water
treatment.
To prevent water leaks:
• The water line tting is to be used with copper tubing
only. Do not use with plastic tubing.
• Do not use any thread sealers on this water line
tting.
NOTE:
Reverse osmosis (RO) water, softened water, and
de-ionized water are not recommended as they
can adversely affect the quality and quantity of
the ice.

USER GUIDE
First Use
ICE
Your ice machine is unique in how it forms ice with
fractional freezing to form a slab of ice that is clear and
has less dissolved solids than the water from which it is
produced. This is accomplished by running water over the
cold evaporator plate which gradually freezes the water to
produce the ice slab. Pure water freezes rst, leaving the
dissolved solids in the residual reservoir water.
When the ice slab reaches the correct thickness, the ice
sheet is released and slides onto the grid cutter. There,
the ice slab is cut into cubes by the grid cutter’s heated
wires. The water containing the dissolved minerals is
drained after each freezing cycle. Fresh water enters the
machine for the next ice making cycle.
The ice machine will keep producing ice until the ice
machine’s bin is full, resuming automatically as needed.
The ice bin is not refrigerated, and some melting will occur
by design to preserve the ice quality and clarity. Allow
your ice machine to run for 24-48 hours to accumulate ice.
The bin level
sensor is located
in the ice bin, it
senses when the
ice supply is low
or full and starts
or stops the ice-
making process
accordingly.
ICE PRODUCTION
In normal mode, the ice machine will produce up to 39
pounds (17.7 kg) of clear ice in a 24-hour period when
installed in a 72
º
F ambient with a 55
º
F water supply.
Note:
“Initial” ice production and ice accumulated in the storage
bin will vary signicantly. This is normal. During the rst
24-hours of operation the unit will produce up to 39 lbs
of ice at the above ambient and water temperatures,
but when starting with an empty ice storage bin, ice
accumulation may only be 18 lbs. By design, the ice
storage bin is maintained at a temperature slightly above
freezing to allow the stored ice to slowly melt, to preserve
the ice quality and clarity and assure a constant supply
of fresh ice. As ice is accumulated in the bin, the ice
production rate will over come the ice melt and the storage
bin will ll to capacity.
NEW SOUNDS
The ice machine will make sounds that are dierent than
your household refrigerator. The ice production process
creates noises such as ice falling onto hard surfaces, water
cascading across the evaporator, and valves opening and
closing. Below are some of the sounds you may hear:
Buzzing - water valve opens to ll water reservoir.
Rattling - water owing through water line.
Splashing - water owing over evaporator plate and into
reservoir.
A “Thud” - ice slab sliding down onto the grid cutter.
Clicks - ice cubes falling into the ice storage bin.
Gurgling - refrigerant owing in the ice machine.
Air - the condenser fan.

the water reservoir by
removing the black plug
from the bottom of the
fresh water reservoir.
4. After the water is
drained, replace the plug in the bottom of the
reservoir.
5. Add cleaning solution to the evaporator plate - refer
to your cleaning solution instructions to determine the
proper amount of solution to add based on 2 quarts
(1.9 liters) of water.
6. Turn the ice machine on
7. On the control, turn on clean mode by holding
for 5 seconds.
8. Your ice maker will ll with water and circulate over the
evaporator for two 15-minute cycles then will resume
normal production.

period of time, or will be in an area that will be near
freezing temperatures, it is necessary to remove any
remaining water in the ice-making system.
This ice machine must have all water drained and
removed to prevent ice machine damage as well
as possible water damage to the surrounding
area in freezing conditions. These damages are
not covered under warranty.
Do not use any type of anti-freeze or other solu-
tion as a substitution for properly draining the
ice machine.
Risk of electrical shock or personal injury could
occur due to moving components, if machine
compartment access cover is removed before
unplugging the ice machine.
CLEAN THE ICE MACHINE
Cleaning the ice machine will help prevent mold and
mildew growth as well as sanitize the ice machine for
storage or when it is put back into service.
(SEE CLEANING SECTION OF THIS GUIDE)

USER GUIDE
Troubleshooting
ELECTROCUTION HAZARD
• Never attempt to repair or perform
maintenance on the appliance until
the main electrical power has been
disconnected. Turning the appliance
control “OFF” does not remove electrical
power from the unit’s wiring.
• Replace all parts and panels before operating.
If the appliance appears to be malfunctioning, read
through this manual rst. If the problem persists, check
the troubleshooting guide below. Locate the problem in the
guide and refer to the cause and its remedy before calling
for service. The problem may be something very simple
that can be solved without a service call. However, it may
be required to contact your dealer or a qualied service
technician.
ICE MACHINE OPERATION
Ice machine does not operate:
• Is the ice machine’s power cord plugged in?
Plug the power cord into a grounded 3 prong outlet.
• Is the electronic control showing the “ICE”
position?
Check the control to be sure it is in the “ICE” position
• Is a fuse blown or a circuit breaker been tripped?
Replace a blown fuse or reset a tripped circuit breaker.
• Is the temperature of the room cooler than it
normally is?
The minimum room temperature is 55°F (13°C). The bin
thermistor may be sensing the room temperature and shut
o before the bin is full of ice. If the room temperature
remains low the ice machine may not restart.
• Is there a drain pump in the ice machine?
The drain pump is designed to temporarily shut the unit
o when large quantities of water create a high-limit
condition. Wait a few minutes as the drain pump will
continue to operate to dispose of the excess water. If there
is still water in the ice bin check the drain pump vent line
and drain line for obstructions or kinking.
BEFORE CALLING FOR SERVICE
Troubleshooting
The ice machine is noisy:
Many sounds of an ice machine are dierent than your
household refrigerator. This subject is discussed on page
11, but check the following:
• Do you hear water being circulated in the ice
machine?
This is a normal sound as water is added once every ice
making cycle.
• Is there a “whooshing” sound?
Make sure water is getting to the ice machine. Also check
to make sure the drain plug is fully seated in the water
reservoir.
• Is there an ice slab caught between the evaporator
plate and the grid cutter?
First check to see if the ice machine is level. If the ice
machine is level run a cleaning cycle.
ICE PRODUCTION
Little or no ice production from the ice machine:
• Is the electronic control set to the “ICE” position?
Check the control to be sure it is in the “ICE” position
• Is water getting to the ice machine?
Make sure nothing is restricting the water supply such
as a closed water valve or a blown fuse or tripped circuit
breaker, or a kinked supply line, or low water pressure.
• Has the ice machine just been started?
A typical ice production cycle can take up to 1
1
⁄2 hours.
Initial start up cycles can take longer. Check the ice
machine after 24 hours for ice accumulation in the bin.
• Is the reservoir drain plug in place?
Check that the reservoir drain plug is properly seated.
• Is the water distributor tube restricted?
Run a cleaning cycle to clean the ice machine. Also check
any lters to make sure they are not restricted.
• Is the condenser fan air ow restricted?
Make sure the grille in the front of the ice machine is open
for proper air circulation.
• Is the room and/or water temperature to warm?
Move the ice machine to an area where the ambient
temperature is below 90°F (32°C) for built-in ice machines
or below 100°F (38°C) for freestanding ice machines. The
ice machine should not be placed next to a heat source
such as an oven. Check the cold water connection.
• Is there scale build up in the ice machine?
If there is scale build up on the evaporator, the ice
machine needs to be cleaned. See “Cleaning the Ice
machine”.
WARNING
!
26
USER GUIDE
Troubleshooting
ICE QUALITY
Odor, grey color, or o taste in the ice:
• Is there mineral scale build up on the evaporator
plate?
The ice machine needs cleaning. See “Cleaning the Ice
Machine”.
• Is there a high mineral content in the water?
The water may need to be ltered.
• Are food items being stored in the ice bin?
Remove food from the ice bin.
• Unpleasant Odors may require the use of a char-
coal lter on the water supply line.
Clumps of ice:
• Are there clumps of ice in the bin?
If the ice isn’t used on a regular basis it will melt and form
into clumps. Break up the ice clumps with the ice scoop.
Ice cubes are too big or too small:
• Is there low ice consumption?
Ice is slowly melting in the ice bin which will aect the size
of the cubes. This is normal. When the ice bin needs to be
replenished, cubes will return to the regular size.
• Is the ice slab releasing?
Clean the evaporator. See “Cleaning the Ice Machine”
• Is the distributor tube restricted?
Check the water line to the ice machine to make sure
there are no restrictions or kinks in the line. Check all
lters to make sure they are not restricted. Check that the
water ows evenly out of the distributor tube, if not, clean
the ice machine. See “Cleaning the Ice Machine”.
PLUMBING PROBLEMS
• Is the drain hose aligned over the drain?
Move the ice machine to align the drain.
• Is the ice machine draining properly?
Check that there are no kinks or restrictions in the drain
lines; this can cause water to back up in the ice bin.
Check that foreign material is not blocking the ice bin drain
located at the right rear corner of the ice bin. Check the
drain pump discharge and vent line or any restrictions or
kinks. Check that the drain pump is level.
NOTE:
If there are plumbing issues outside of the ice
machine, they cannot be repaired by the service
technician. A qualied plumber will have to be
called.
TROUBLESHOOTING THE DRAIN PUMP
NOTE:
If the drain pump reservoir (not the ice machine
bin) reaches overll condition, the power to the
ice machine will be shut o.
If the ice machine is not working, check the
following:
• Make sure there is power at the receptacle.
• Make sure the ice machine is turned on.
• Make sure the ice bin is not full.
Then check the drain pump:
The pump does not run:
• Make sure the pump is plugged in and there is power
to the receptacle.
• Check the inlet to the drain pump for debris and clean
as needed. Remove clamps and inlet tube from drain
pump to check for and remove debris.
• Make certain the vent line is free of kinks/sharp bends
or restrictions.
• Make certain there is enough water to activate the
drain pump. It will take at least one (1) quart (.95
liters)of water to activate the drain pump.
The pump runs, but no water is pumped out:
• Check that the vent is clear and free of restrictions.
• Check the discharge line to make certain there are no
restrictions.
• Make sure that the discharge tubing has not exceeded
the maximum lift of eight (8) feet (2.44 meters) and
the horizontal run is not greater than twenty (20) feet
(6.1 meters).
The pump runs and then quickly turns o
repeatedly:
• Check to make certain the drain pump is level.
• Check that the vent is clear and free of restrictions.
The ice machine is running but not producing ice:
• Check to make sure water is not backing up in the ice
bin.

USER GUIDE
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.
