SAVE THESE INSTRUCTIONS
Electrical Connection
Do not, under any circumstances, cut or remove the third (ground) prong from the power
cord. For personal safety, this appliance must be properly grounded. The power cord of
this appliance is equipped with a 3-prong grounding plug that mates with a standard
3-prong grounding wall outlet to minimize the possibility of electric shock hazard from
the appliance. Have the wall outlet and circuit checked by a qualified electrician to make
sure the outlet is properly grounded. When a standard 2-prong wall outlet is encountered,
4
it is your responsibility and obligation to have it replaced with a properly grounded
3-prong wall outlet. The ice maker should always be plugged into its own individual
electrical outlet which has a voltage rating that matches the rating label on the appliance.
This provides the best performance and also prevents overloading house wiring circuits
which could cause a fire hazard from overheated wires. Never unplug your ice maker by
pulling on the power cord. Always grip the plug firmly and pull straight out from the
outlet. Repair or replace immediately all power cords that have become frayed or
otherwise damaged. Do not use a cord that shows cracks or abrasion damage along its
length or at either end. When moving the ice maker, be careful not to damage the power
cord.
Extension Cord
Because of potential safety hazards under certain conditions, it is strongly recommended
that you do not use an extension cord with this ice maker.

ICE MAKER INSTALLATION
Unpacking
Excessive Weight Hazard
Use two or more people to move and install ice maker.
Failure to do so can result in back or other injury.
Remove packaging materials
IMPORTANT: Do not remove any permanent instruction labels or the data label on your
ice maker.
Remove tape and glue from your ice maker before using.
To remove any remaining tape or glue, rub the area briskly with your thumb. Tape or
•
glue residue can also be easily removed by rubbing a small amount of liquid dish soap
over the adhesive with your fingers. Wipe with warm water and dry.
Do not use sharp instruments, rubbing alcohol, flammable fluids, or abrasive cleaners
•
to remove tape or glue. These products can damage the surface of your ice maker.
Cleaning before use
After you remove all of the packaging materials, clean the inside of your ice maker before
using it. See “Interior Cleaning” in the Cleaning and Maintenance section.
Location Requirements
INSTALLATION CLEARANCES:
TOP VIEW
SIDE VIEW
8
To ensure proper ventilation for your ice maker, the front of the unit must be
•
completely unobstructed. Allow at least 101 mm (4”) clearance at rear, and 15 mm
(0.6”) at top and sides for proper air circulation. The installation should allow the ice
maker to be pulled forward for servicing if necessary.
When installing the ice maker under a counter, follow the recommended spacing
•
dimensions shown. Place electrical and water supplies and drain fixtures in the
recommended locations as shown.
Choose a well-ventilated area with temperatures above 55ºF (13ºC) and below 90ºF
•
(32ºC). This unit MUST be installed in an area protected from the elements, such as
wind, rain, water spray or drips.
The unit should not be located next to ovens, grills or other sources of high heat.
•
Installation of the ice maker requires a cold water supply inlet of 6.35 mm (1/4 in.)
•
soft copper tubing with a shut-off valve and a gravity-drain system.
(NOTE: Runoff water can also be drained into a sink via a pump – not included –
when a gravity drain is not available.)
The ice maker requires a continuous water supply with a minimum pressure of 20
•
psig and a static pressure not to exceed 80 psig. The temperature of the water feeding
into the ice maker should be between 41ºF (5ºC) and 77ºF (25ºC) for proper
operation.
Normal operating ambient temperature should be between 55ºF
(13ºC) to 90ºF (32ºC). Normal operating water temperature
should be between 41ºF (5ºC) and 77ºF (25ºC). Operation of
the ice maker for extended periods outside of these normal
temperature ranges may affect production capacity.
In general, it is always a good idea to filter the water. A water filter, if it is of the
•
proper type, can remove taste and odors as well as particles. Where water is very
hard, softened water may result in white, mushy cubes that stick together. Deionized
water is not recommended.
The ice maker must be installed with all electrical, water and drain connections in
•
accordance with state and local codes.
The unit should be located on a firm and level surface. It is important for the ice
•
maker to be leveled in order to work properly. If needed, you can adjust the height of
the ice maker by revolving the feet. See the “Leveling the Ice Maker” section.
9
A standard electrical supply (115 VAC only, 60 Hz, 15 A), properly grounded in
•
accordance with the National Electrical Code and local codes and ordinances is
required.
IMPORTANT: Do not kink or pinch the power supply cord between the ice maker
•
and wall or cabinet.
Electrical Requirements
Electrical Shock Hazard
Plug into a grounded 3-prong outlet.
Never remove the grounding prong from the plug.
Never use an adapter.
Never use an extension cord.
Failure to follow these instructions can result in fire,
electrical shock or death.
Before you move your ice maker into its final location, it is important to make sure you
have the proper electrical connection.
A standard electrical supply (115 VAC only, 60 Hz, 15 A), properly grounded in
accordance with the National Electrical Code and local codes and ordinances, is required.
It is recommended that a separate circuit, serving only your ice maker, be provided. Use
receptacles that cannot be turned off by a switch or pull chain.
The fuse (or circuit breaker) size should be 15 amperes.
Recommended grounding method
For your personal safety, this appliance must be grounded. This appliance is equipped
with a power supply cord having a 3-prong grounding plug. To minimize possible shock
hazard, the cord must be plugged into a mating 3-pronged and grounding-type wall
receptacle, grounded in accordance with the National Electrical Code and local codes and
ordinances. If a mating wall receptacle is not available, it is the personal responsibility of the
customer to have a properly grounded, 3-prong wall receptacle installed by a qualified electrician.
10
Leveling the Ice Maker
It is important for the ice maker to be leveled in order to work properly. It can be raised
or lowered by rotating the plastic sheaths around each of the four rolling casters on the
bottom of the machine. If you find that the surface is not level, rotate the casters until the
ice maker becomes level. You may need to make several adjustments to level it. We
recommend using a carpenter’s level to check the machine.
You will find that the casters make it easy for one person to move the machine. This is
useful for cleaning and sanitizing the surface on which the ice maker is installed because
it allows you to move the unit and have easy access to the surface to be cleaned.
IMPORTANT: Once you are ready to install the ice maker in a cabinet or directly on the
floor, you must adjust the feet to level the ice maker and lock the rollers. If the floor is
level, just revolve the two front feet to touch the floor. (See illustration.)
Water Supply and Drain Connections
The water supply and drain should be ready at the point of installation. A wall outlet
directly behind the ice maker will make installation easier.
IMPORTANT:
1. All installations must be in accordance with local plumbing code requirements.
Professional installation is recommended.
2. Make certain that the hoses are not pinched or kinked or damaged during installation.
3. Check for leaks after connection.
Tools required:
1/2 in. open-end wrench
•
Phillips screwdriver
•
11
Connecting the water line:
1. Turn off main water supply. Turn on nearest faucet long enough to clear line of water.
2. Find a 1/2 in. to 3/4 in. vertical cold water pipe near the installation location. The
distance should be less than 10 feet. The water supply hose provided with the ice
maker is about 10 feet.
3. A shut-off valve must be installed to the main water supply. If the water pipe has a
plain piece of copper tubing, attach a ¼” O.D. compression union to the tubing and
remove the nut.
4. Connect nuts of water supply hose to tap and water inlet valve. Tighten firmly by
hand, then one-half turn with wrench.
5. Turn on main water supply and tap. Check for water supply connection leaks. Tighten
any connections (including connections at the valve) or nuts that leak.
Water tap (1/4” o.d.)
Water inlet valve
Nut of water
draining hole
Drain outlet
Water supply line
Floor drain
NOTE: Connection to the water line may vary according to installation requirements.
Connecting the drain line:
A gravity drain system is used in this type ice maker. Excess water flows to the drain
through the drain line provided with the ice maker.
1. Find the floor drain near the ice maker. The distance should be less than 10 feet as the
length of the long drain line provided with the ice maker is about 10 feet.
2. Find the drain outlet on the back of ice maker. Connect one end of the long drain line
to the drain outlet of the machine, the other end to the floor drain.
3. All horizontal runs of drain lines must have a fall of ¼” per foot. An air gap will
likely be required between the ice maker drain tube and the drain/waste receptacle. A
standpipe with a trap below it would be acceptable for the drain/waste receptacle.
NOTE: If you cannot locate a floor or wall drain that allows the drain line to descend
¼” per foot, you may wish to purchase a drain pump from your local Franklin supplier.
Drain line
4. Pour 1 gallon of water into the ice storage bin to check for leaks at all drain connections
and at the nut of the drain water hole. Tighten any connections or nuts that leak.
IMPORTANT: Poor drainage will cause a high rate of ice melting in the ice storage bin.
12
Installation Types
This ice maker has been designed for Mobile (free-standing) installation. It can also be
Enclosed (as under a cabinet) or Built-in (sealed to the floor), although this last option is
not the preferred method of installation. In every case, there must be adequate air space
around the unit for ventilation purposes (see diagrams on page 8).
Mobile Installation:
A mobile installation will allow you to install the icemaker free-standing in any place you
desire provided you have access to a water supply and drainage facilities. You must
follow the stated instructions for
a. Electrical requirements
b. Water supply and drain connections
c. Leveling the icemaker.
Enclosed Installation:
An enclosed installation will allow you to install the ice maker under a cabinet, or in a
kitchen cabinet provided the required clearance space around the ice maker is respected.
This installation has the same requirements as a mobile installation.
The unit should be placed in the cabinet by sliding it into the cabinet’s opening and then
leveling it properly.
IMPORTANT: For Mobile and Enclosed installations you must use flexible water and
drain connections to the water supply and drain. This will allow the moving of the ice
maker for cleaning. Use the water and drain hoses supplied with the unit for these
connections.
Built-in Installation:
If this method of installation is chosen, it will still be necessary to allow adequate
ventilation space around the unit. The following additional items must be observed.
1. Place the ice maker in front of the installation location. Remove the feet and place
the unit flat on the floor or on a platform depending on your installation requirements.
2. The water supply line and drain line must be plumbed before connecting to the ice
maker.
3. Turn on the main water supply and tap. Check for water supply connection leaks.
Tighten any connections (including connections at the valve) or nuts that leak.
4. Pour 1 gallon of water into the ice storage bin to check for leaks at all drain connec-
tions and the nut of the drain water hole. Tighten any connections or nuts that leak.
(This procedure will also indicate if the drainpipe is kinked or pinched.)
13
5. If the electrical outlet for the ice maker is behind the cabinet, plug in the ice maker.
6. Push the ice maker into position.
7. Seal all around the cabinet to the floor with an approved caulking compound.

Final Check List before Operation
1. Have all packing materials and tape been removed from the interior and exterior of
the ice maker?
2. Did you clean the ice storage bin?
3. Have the installation instructions been followed, including connecting the machine to
water, drain and electricity?
4. Has the machine been leveled?
5. Is the ice maker in a site where the ambient temperature is between 13º C (55º F) and
32ºC (90ºF) and the water temperature within 5º C (41º F) and 25º C (77º F) all year
round?
6. Has the water supply pressure been checked to ensure a minimum of 20 psig with a
static pressure not to exceed 80 psig?
7. Is there a clearance of at least 4 in. (101 mm) at the rear, and 0.6 in. (15 mm) at the
sides and top for proper air circulation?
8. Has the power supply voltage been checked or tested against the nameplate rating?
And has proper grounding been installed in the ice maker?
9. Is the ice maker plugged in?
10. Did you turn on the main water supply and the tap?
11. Did you check for leaks at all water supply and drainpipe connections?
14
Operating Method
1. Switch on the Power switch on the right
side panel. The light will be on. The ice
maker will start working automatically
and feeding water.
2. After the first feeding of the water, the
machine will automatically go to the ice
making stage, and the sound of water
spraying will be heard.
3.
Ice will be harvested to the ice storage
bin. When the storage bin is filled to the
point that the ice-full sensor is covered,
the ice maker will automatically stop
working. The machine will restart
making ice once the storage bin is less
than full.
4. Excess water will flow through the drain
outlet at the back of the machine and empty into the floor drain.
IMPORTANT:
Although the unit has been tested at the factory, due to long-term transit and storage,
•
the first batch of cubes must be discarded.
Never turn the water supply tap off when the icemaker is working.
•
How the Machine Makes Ice
There are two distinct cycles: freeze and harvest.
During the freeze cycle, water is sprayed against the evaporator surface.
In the harvest cycle, the ice is released and water enters the machine. A complete cycle
takes about 20 minutes, but is dependent on temperature and operating conditions.
Freeze: During the freeze cycle the compressor is pumping refrigerant, the fan motor is
blowing air, and the water pump is circulating water. When the batch of ice has been
fully formed, the ice maker stops the freeze cycle and begins to harvest the ice.
15
Harvest: During the harvest cycle the compressor is still operating, but the water pump
has stopped. Two other components have been energized: the hot gas valve and the water
inlet valve. These two valves open and warm up the freezing surface, allowing the cubes to
fall into the bin. The freeze cycle will restart when all the cubes have been harvested.
How the machine uses water:
Evaporator
Water pump
Hot gas valve
Condenser
Compressor
Fan motor

freezing portion of the ice-making cycle, the water in the sump will become highly
concentrated with mineral impurities.
The ice maker
begins with a fixed
charge of water that
is contained in the
water sump. As the
water is sprayed
against the freezing
evaporator surface,
the portion of water
that does not contain
mineral impurities
will freeze and stick
to the ice cube molds.
The water containing
impurities falls back
into the water sump.
Gradually, during the
During the harvest cycle, fresh water flows into the machine to dilute the bin water and
rinse the concentrated minerals down the drain.
Normal Sounds
Your new ice maker may make sounds that are not familiar to you. Most of the new
sounds are normal. Hard surfaces like the floor and walls can make the sounds seem
louder than they actually are. The following describes the kinds of sounds that might be
new to you and what may be making them.
You will hear a swooshing sound when the water valve opens to fill the water sump
•
for each cycle.
Rattling noises may come from the flow of the refrigerant or the water line. Items
•
stored on top of the ice maker can also make noises.
The high-efficiency compressor may make a pulsating or high-pitched sound.
•
16
Water running from the water sump to the evaporator plate may make a splashing
•
sound.
Water running from the evaporator to the water sump may make a splashing sound.
•
As each cycle ends, you may hear a gurgling sound due to the refrigerant flowing in
•
your ice maker.
You may hear air being forced over the condenser by the condenser fan.
•
During the harvest cycle, you may hear the sound of ice cubes falling into the ice
•
storage bin.
When you first start the ice maker, you may hear water running continuously. The ice
•
maker is programmed to run a rinse cycle before it begins to make ice.
Preparing the Ice Maker for Long Storage
If the ice maker will not be used for a long time, or is to be moved to another place, it
will be necessary to drain the system of water.
1. Shut off the water supply at the main water source.
2. Disconnect the water supply line from the water inlet valve.
3. Disconnect the drain pipe to the drain line or floor drain.
4. Allow the ice maker to run for an hour or more until all remaining ice cubes have
been ejected from the ice maker assembly.
5. Shut off the electric supply at main electrical power source.
6. Screw off the nut of the water drain hole at the back of the machine, drain out water
residue completely (do not loosen or screw off the nut at other times), then tighten the
nut after finishing.
7. Drop the door open to allow for circulation and prevent mold and mildew.
8. Leave water supply line and power cord disconnected until ready to reuse.
17
CLEANING AND MAINTENANCE
If the ice maker is left unused for a long time, before the next
use it must be thoroughly cleaned. Follow carefully any
instructions provided for cleaning or use of sanitizing solution.
Do not leave any solution inside the ice maker after cleaning.
Periodic cleaning and proper maintenance will ensure efficiency, top performance, and
long life. The maintenance intervals listed are based on normal conditions. You may want
to shorten the intervals if you have pets, or the unit is used outdoors, or there are other
special considerations.
What shouldn’t be done
Never keep anything in the ice storage bin that is not ice: objects like wine and beer
bottles are not only unsanitary, but the labels may slip off and plug up the drain.
What should be kept clean
There are 4 things to keep clean:
1. The exterior
2. The condenser
3. The interior
4. The ice making system
Before proceeding with cleaning and maintenance operations,
make sure the power line of the unit is disconnected and the water
line is shut off (EXCEPTION: Ice maker system cleaning).
Exterior Cleaning
The door and cabinet may be cleaned with a mild detergent and warm water solution such
as 1 oz of dishwashing liquid mixed with 2 gallons of warm water. Do not use solventbased or abrasive cleaners. Use a soft sponge and rinse with clean water. Wipe with a soft
clean towel to prevent water spotting.
18
Stainless steel can discolor when exposed to chlorine gas and should be cleaned. Clean
stainless steel with a mild detergent and warm water solution and a damp cloth. Never
use abrasive cleaning agents.
NOTICE: Stainless steel exposed to chlorine gas and moisture, such as in areas with
spas or swimming pools, may show some discoloration. Discoloration from chlorine gas
is normal.
Condenser Cleaning
A dirty or clogged condenser prevents proper airflow, reduces ice making capacity, and
causes higher than recommended operating temperatures that may lead to component
failure. Have the condenser cleaned at least once every six months.
1. Unplug the ice maker or disconnect power.
2. Remove the 2 screws at the bottom of the front cover.
3. Grasp the lower edge of the front cover at the right and left sides, raise it a little and
then pull down.
NOTE: Do not use too much force, as the wire leads connected to the power switch
can be inadvertently disconnected.
4. Locate the condenser surface.
Condenser
surface
5. Remove dirt and lint from the condenser fins and the unit compartment with a brush
attachment on a vacuum cleaner.
6. Reassemble the front cover.
7. Plug in the ice maker or reconnect power.
DO NOT touch condenser fins. They are sharp and
can be damaged easily.
19
Interior Cleaning
The ice storage bin should be sanitized occasionally. Clean the bin before the ice maker is
used for the first time and reused after stopping for an extended period of time. It is
usually convenient to sanitize the bin after the ice making system has been cleaned and
the storage bin is empty.
1. Disconnect power to the unit.
2. Open the door and with a clean cloth, wipe down the interior with a sanitizing
solution made of 1 ounce of household bleach or chlorine and 2 gallons of hot water
(95º to 115ºF).
3. Rinse thoroughly with clear water. The waste water will be drained off through the
drainpipe.
4. Reconnect power to the unit.
The ice scoop should be washed regularly. Wash it just like any other food container.
DO NOT use solvent-based cleaning agents or abrasives on
the interior. These cleaners may transmit taste to the ice
cubes, or damage or discolor the interior.
IMPORTANT NOTE: The sprinkler should only be cleaned when you find that some of
the ice cubes are improperly shaped during ice making. Cleaning the ice making system
should follow cleaning of the sprinkler.
1. Disconnect power to the unit and open the door.

4. Find the sprinkler arm and raise it. Disconnect it from the water tube which is
connected at the back of the sprinkler arm.
5. A de-scaling solution can be prepared in a plastic basin with Nu-Calgon Nickel-Safe
Ice Machine Cleaner. Mix 4 ounces of the ice machine cleaner per gallon of warm
water.
6. Wipe down the interior of the water sump with the de-scaling solution and warm
water. Rinse thoroughly with clear water.
7. Reassemble the sprinkler arm, slideway and row of flake covers.
8. Perform steps 1, 3, 6, 7 and 8 of the Ice Making System Cleaning procedure below.
Ice Making System Cleaning
Minerals that are removed from water
during the freezing cycle will eventually
form a hard scaly deposit in the water
system. Cleaning the system regularly helps
remove the mineral scale buildup. How
often you need to clean the system depends
upon how hard your water is or how
effective your filtration may be. With hard
water of 15 to 20 grains/gal. (4 to 5
grains/liter), you may need to clean the
system as often as every 6 months.
1. Turn off power to the ice maker. Keep the ice maker connected to the water supply
and drainpipe.
2. Open the door and scoop out all of the ice cubes. Either discard them or save them in
an ice chest or cooler.
3. Remove the 2 screws in the front cover and push for-
ward to remove the front cover. Locate the control box.
NOTES: Do not use too much force, as the wire leads
connected to the power switch can be inadvertently
disconnected.
Use care in the area of the control box. Do not expose
it to moisture.
4. Turn on the power to the ice maker. Pour 8 oz. of
Nickel-Safe Ice Machine Cleaner solution into the
water sump. Add 8 oz. of tap water. After
about 5 minutes, press down the “Clean”
button on the Control Box. (See figures
here and on page 24.) The machine will
run the Automatic Clean Mode.

5. Allow 30 minutes for proper cleaning. After cleaning, shut off the power switch, and
unscrew the nut of the water-draining hole on the rear of the unit. Drain off the waste
water to some container, and then screw the nut on tightly when the waste water is
fully drained off.
The ice machine cleaner contains acids.
DO NOT use or mix with any other solvent-based cleaner
products.
Use rubber gloves to protect hands. Carefully read the material
safety instructions on the container of the ice machine cleaner.
DISCARD the first batch of ice produced after cleaning.
6. Repeat steps 4 and 5 (without Ice Maker Cleaning Solution) to rinse the ice making
system 3 times.
NOTE: The use of the Ice Maker Cleaner Solution in the water sump during the rinse
is not needed.
7. Prepare a sanitizing solution made of 1 ounce of household bleach and 2 gallons of
hot water (95º to 115º F). Remove the flake covers and slideway from the water sump
and wipe the entire bin inside and out, covering the entire surface of the walls.
8. Fill a spray bottle with the sanitizing solution and spray all corners and edges, making
sure to cover all surfaces with the solution. Soak the flake covers and slideway in the
solution and put back in place after drying.
9. Allow the solution to be in contact for at least 3 minutes, then dry.
10. Repeat step 6 to rinse the ice making system one more time.
11. Reassemble the front cover.
12. Turn on the power again. The machine will return to the regular ice making mode.
Discard the first batch of ice.

Control Box (behind front cover)
Descriptions of LEDs and buttons:
1. Red LED: Ice Full indicator light.
When this LED is lit, the ice storage bin is full of ice or there is something between
the two arms of the ice-full sensor in the ice storage bin. The unit will stop working.
When ice cubes are taken out o f the ice storage bin, clearing the sensor, the red LED
will keep flashing for 3 minutes. Then the unit will restart and return to the ice
making mode.
2. Green LED: Ice Making indicator light.
When this LED is lit, the unit is working in the Ice Making mode controlled by a
temperature probe on the evaporator. When the green LED is flashing, the unit is
working in the Ice Making mode controlled by a fixed timer.
24
3. Yellow LED: Ice Harvest indicator light.
When this LED is lit, the unit is working in the Ice Harvest mode controlled by a
temperature probe on the evaporator. When the yellow LED is flashing, the unit is
working in the Ice Harvest mode controlled by a fixed timer.
4. Clean button: When this button is pressed, the unit enters the Cleaning mode. The
green and yellow LEDs flash together. To stop the Cleaning mode, just press the
button again.
5. Mode button: Mainly for service. When this button is pressed, unit can change from
Ice Making mode to Ice Harvest mode, or from Ice Harvest mode to Ice Making
mode. You can judge the mode from the status of the green and yellow LEDs.
6. Ice size adjust: Turn the screw clockwise, and the size of individual ice cubes will
be larger in the next cycle; the cycle time will be longer. Turn the knob counterclockwise, and the ice size will be smaller in the next cycle. It is not recommended
that the ice size be adjusted after installation.
