Important:
1. All installations must be in accordance with local plumbing code requirements.
2. Make certain that the pipes are not pinched or kinked or damaged during installation.
3. Check for leaks after connection.
Note: In general, it is always a good idea to filter the water. A water filter 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.
Water Supply Connections
The water supply should be ready at the point of installation. The water supply pressure should be a
minimum of 15 psig with a static pressure not more than 80 psig. (A wall outlet directly behind the ice
maker will make installation easier.)
Tools required: ½ in. open-end wrench, Phillips screwdriver
Connecting the Water Line
1. Turn off the main water supply. Turn on the nearest faucet long enough to clear the line of
water.
2. Find a 1/2” to 3/4” vertical cold water pipe near the installation location. The distance should be
less than 9 feet. The water supply hose provided with the ice maker is about 9 feet long.
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 1/4" O.D. compression union to the tubing and remove the nut.
4. Connect nuts of the water supply hose to the tap and water inlet valve. Tighten the nuts firmly
by hand, then one-half turn with wrench.
5. Turn on the main water supply and tap. Check for water supply connection leaks. Tighten every
connection (including connections at the water inlet).
8
Note: There is a drain outlet on the ice maker. Please drain water through the drain hose provided
with the ice maker.
Connecting the Drain Line:
Note: A condensate pump can allow for installation further from your drain. Consult your plumber
for advice.
1. Locate the floor drain near the ice maker. The distance should be less than 4.5 feet since the
length of the long drain hose provided with the ice maker is about 4.5 feet.
2. Connect the drain hose to the back of ice maker, then insert the other end of the hose into the
drain line.
3. All horizontal runs of drain lines must have a fall of 1/4” per foot. An air gap will likely be required
between the ice maker drain hose and the drain/waste receptacle. A stand pipe with a trap
below it would be acceptable for the drain/waste receptacle. A floor drain is also acceptable.
4. Pour 1 gallon of water into the ice storage bin to check for proper drainage.
Operation
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 and
electricity? Does the unit have proper drainage?
4. Has the machine been leveled?
5. Is the ice maker in a site where the ambient temperature is between 50º F and 100ºF and the
water temperature between 41º F and 90º F all year round?
6. Has the water supply pressure been checked to ensure a minimum of 15 psig with a static
pressure not to exceed 80 psig?
7. Is there a clearance of at least 2” at the rear and 1/4” at the top and sides for proper air circulation?
8. Has the power supply voltage been checked or tested against the nameplate rating? And has
proper grounding been installed for the ice maker?
9. Is the ice maker plugged in?
10. Have you turned on the main water supply and the tap?
11. Have you checked for leaks at all water supply connections - and at the drain?
9
Important:
• Although the unit has been tested and cleaned at the factory, due to long-term transit and
storage, the first batch of ice cubes must be discarded.
• Never turn the water supply tap off when the ice maker is working.
• Never touch the evaporator when the machine is running.
• Except to take ice from the unit, keep the door closed to reduce melting and ensure proper ice
formation.
Operating Method
1. Turn on the water tap, let the water trough fill, and then switch the ICE/OFF/WASH switch on the
front panel to the ICE position. The ice maker will start working automatically.
2. After three minutes, the machine will automatically go to the ice making stage, and the sound of
flowing water will be heard.
3. When the batch of ice has been fully formed, ice will automatically be harvested to the ice
storage bin.
4. When the ice storage bin is full, the sheet of cubes will not fall completely and will hold the ice
slide down. The machine stops making ice and automatically.
5. The unit will start making ice again after the ice cubes are removed. At that time, the ice slide will
swing back to operating position.
How the machine Makes Ice
Turn the ICE/OFF/WASH switch to the ICE position. The machine will automatically start the ice
making stage. There are two distinct cycles: freeze and harvest. During the freeze cycle, water flows
across the evaporator surface to form the icde. In the harvest cycle, the ice is released. A complete
cycle can take 15 to 40 minutes, depending 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 the harvest cycle.
Harvest
During the harvest cycle the compressor is still operating, but the water pump has stopped. The
hot gas valve opens, diverting hot refrigerant gas into the evaporator. The gas warms the
evaporator, causing the cubes to slide, as a unit, off the evaporator and into the storage bin. The
freeze cycle will restart when all the cubes have been harvested.
10
How the Machine Uses the Water
The ice maker begins with a fixed charge of water that is contained in the water trough. During the
ice-making process, fresh water enters the water trough continuously as the water from the trough
freezes on the evaporator.
Control Panel (rear of unit)
1. Ice Full (Red) LED: Ice Full indicator light.
When this LED is lit, the ice storage bin is full of ice or there is something obstructing the ice
slide. The unit will stop producing ice. When ice cubes are removed from the ice storage bin,
clearing the ice slide, the red LED will keep flashing for 3 minutes. Then the unit will restart
and return to the ice making mode.
2. Ice Making (Green) LED: Ice Making indicator light.
When this LED is lit or flashing, the unit is working in the ice making mode.
3. Ice Harvest (Yellow) LED: Ice Harvest indicator light.
When this LED is lit, the unit is working in the Ice Harvest mode.
11
4. Mode button: Mainly for service.
Important:
• It is not recommended that the ice size be adjusted unnecessarily since this could damage the
machine’s controls.
• Do not let water contact the control panel.
When this button is pressed, the unit can change from Ice Making mode to Ice Harvest
mode, or from Ice Harvest mode to Ice Making mode. The mode can be determined from the
status of the green and yellow LEDs.
5. Ice Size Adjust button: When this is pressed and held for 3 seconds, the unit will enter the
Ice Size Adjustment mode. Once in this mode, press 'Clean' to decrease the ice size, or press
'Mode' to increase the ice size. Please note that there are five larger ice sizes and five smaller
ice sizes from the default setting. The current ice size can be determined from the status of the
red, green, and yellow LEDs. The green, yellow, and red LEDs flashing synchronously
indicates the default ice size. When decreasing the ice size with the ‘Clean’ button, the red
LED will flash once and the green LED will flash continuously. The red and green LEDs flashing
synchronously indicate that the smallest ice size has been reached. When increasing the ice
size with the ‘Mode’ button, the yellow LED will flash once and the green LED will flash
continuously. The yellow and green LEDs flashing synchronously indicate that the largest ice
size has been reached.
Normal Sounds
Your new icemaker 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.
• Ratting noises may come from the flow of the refrigerant or the water line. Items stored on top of
the icemaker can also make noises.
• The high efficiency compressor may make a pulsating or high-pitched sound.
• Water running from the evaporator to the water bin may make a splashing sound.
• As each cycle ends, you may hear a gurgling sound due to the refrigerant flowing in your
icemaker.
• 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 storing bin.
12
Important: Do not touch the power plug when your hands are wet. Never unplug the unit by pulling
on the plug.
Note: Never keep anything in the ice storage bin that is not ice: objects like wine or beer bottles are
not only unsanitary, but the labels may slip off and plug up the drain.
Preparing the Icemaker for Long Storage
Caution: The icemaker must be thoroughly cleaned if it has been left unused for a long time. Follow
carefully any instructions provided for cleaning or use of sanitizing solution. Do not leave any
solution inside the icemaker after cleaning.
Warning: 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: Cleaning of the ice-making
system)
If the icemaker 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.
3. Shut off the electric supply at the main electrical power source.
4. Take out the ice storage bin to remove ice and water. Dry it.
5. Pull off the water trough’s drainage tube to drain off all water. Dry out the trough.
6. Leave the door open to allow for circulation and to prevent mold and mildew.
7. Leave the water supply line and power cord disconnected until ready to reuse.
Cleaning and Maintenance
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 there are other special considerations.
What Should be Kept Clean?
There are 5 things to keep clean:
1. The exterior
2. The interior
3. The condenser
4. Water distribution tube
5. The ice-making system
13
Exterior Cleaning
Warning: 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.
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 solvent based or abrasive
cleaners. Use a soft sponge and rinse with clean water. Wipe with a soft clean towel to prevent
water spotting. If the door panel is stainless finish, it can discolor when exposed to chlorine gas and
moisture. Clean stainless finish with a cloth dampened with a mild detergent and warm water. Never
use an abrasive cleaning agent.
Ice Bin and Water Trough Cleaning
The ice storage bin should be sanitized occasionally. Clean the water trough 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 trough after the ice making system has been cleaned (see section Ice
Making System Cleaning) and the ice storage bin is empty.
1. Disconnect power to the unit.
2. Open the door and take out the removable storage bin. With a clean cloth, wipe down the interior
of the unit with a sanitizing solution made of 1 ounce of household bleach and 2 gallons of hot
water (95º F to 115º F).
3. Rinse thoroughly with clean water.
4. Put the cleaned and empty ice storage bin back inside the unit.
5. Reconnect power to the unit.
The ice scoop should be washed regularly. Wash it just like any other utensil.
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 and gently pull it off.
Leave the wiring to the switch connected.
3. Locate the condenser directly behind the front cover.
14
Warning: DO NOT touch the condenser fins. They are sharp and can be damaged easily.
Caution:
• Many ice machine cleaners contain acids.
• DO NOT use or mix with any other solvent-based cleaner products.
• Use rubber gloves to protect your hands.
• Carefully read all safety instructions printed on the container of the ice machine cleaner.
• Discard the first batch of ice produced after cleaning
4. Remove dirt and lint from condenser and the unit compartment with a brush attachment on a
vacuum cleaner.
5. Reattach the front cover.
6. Plug in the icemaker or reconnect power.
Water Distribution Tube Cleaning
When you find that the ice cubes are incompletely formed or the output of ice cubes is low, the
water distribution tube may be blocked. Set the ICE/OFF/WASH switch to OFF, rotate the water
distribution tube, and locate the holes in the distribution tube. Using a toothpick or similar tool,
dredge the holes, then rotate the water distribution tube back to its original position. If the tube is
badly blocked, clean it as follows:
1. Shut off the water supply.
2. Disconnect the water hose from the distribution tube by cutting the zip tie.
3. Remove the 2 Phillips screws from the splash guard and set the parts aside.
4. Lift the right side of the water distribution tube , then remove it.
5. Remove the inner tube from the outer tube.
6. With a brush, clean the tube with a dilute solution of warm water and a mild detergent such as
dishwashing liquid. After removing the dirt and debris from the surface, rinse the tubes with clean
water.
7. Replace the inner tube into the outer tube making sure it lines up correctly. The notch on the inner
tube must lock into place. The inner tube should not rotate when inserted correctly. The water
distribution tube will leak in not reassembled correctly.
8. Reconnect the water hose and replace the zip tie.
9. Replace the water distribution tube into the unit.
10. Replace the splash guard.
11. Turn on the water supply.
15
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. Make sure that all the ice is off of the evaporator. If ice is being made, wait for cycle completion,
then turn the machine “OFF” at the ICE/OFF/WASH selector switch.
