WARNING
Normal operating ambient temperature should be between 50°F (10°C) to 99°F
(37°C).
Normal operating water temperature should be between 40°F (4°C) and 90°F (32°C).
Operation of the ice maker for extended periods outside of these normal temperature
ranges may affect production capacity.
•It is strongly recommended that a water filter be used. A filter, if it is of the proper type, can remove taste and
odors as well as particles. Some water is very hard, and softened water may result in white, mushy cubes that
stick together. Deionized water is not recommended.
•Theicemakermustbeinstalledwithallelectricalandwaterconnectionsinaccordancewithallstateandlocalcodes.
•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 caster. See the “Leveling
the Ice Maker” section.
• A standard electrical supply (115V AC only, 60Hz, 15A), 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 icemaker and wall or cabinet.
Electrical Requirements
DANGER
Electrical Shock Hazzard
Plug into a grounded 3-prong outlet. Never remove the ground 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.
It is important to make sure you have the proper electrical connection:
A standard electrical supply, properly grounded in accordance with the National Electrical Code and local codes
and ordinances, is required. The ice maker should always be plugged into its own dedicated electrical outlet. It is
recommendedthataseparatecircuit,servingonlyyouricemaker,beprovided.Usereceptaclesthatcannotbeturned
offbya switchorpullchain.Thefuse(orcircuitbreaker)sizeshouldbe15amperes.
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.
Leveling The Ice Maker
It is important for the ice maker to be leveled in order to work properly. Otherwise water
will not flow properly through the evaporator (ice mold). The ice production will be less
than normal, and may be noisy. 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 ice maker.
1. Place a carpenter’s level on top of the unit to see if the ice maker is level from
front to back and side to side.
2. Adjust the height of the casters as follows:
Turn the leveling casters clockwise to lower that side of the ice maker.
Turn the leveling casters counterclockwise to raise that side of the ice
maker.
You will find that the casters make it easy for one person to move the ice maker. 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.

Water Supply
The water supply should be ready at the point of installation. The water supply pressure should be a minimum of 15 psi (1
bar or 103 kPa) with a static pressure not more than 75 psi (5.2 bar or 517 kPa). (A wall outlet directly behind the ice maker
will make installation easier.)
NOTE:
All installations must be in accordance with local plumbing code requirements.
Professional installation is recommended. Make certain the hoses are not pinched, kinked or damaged
during installation. Check for leaks after connection.
Tools Required
½" open-end wrench, Phillips screwdriver
Connecting The Water Line
1. Turn off main water supply. Turn on the nearest faucet long enough to clear line ofwater.
2. Find a ½" to ¾" vertical cold water pipe near the installation location. The distance should be less than 6 feet.
The water supply hose provided with the ice maker is about 6 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 ¼" O.D. compression union to the tubing and remove the nut.
4. Connect the nut of the water supply hose to the tap, and connect the other end with the water inlet. Tighten
firmly by hand, then one-half turn withwrench.

9
Drain
5. Turn on the main water supply and tap. Check for water supply connection leaks. Tighten every connection
(including connection at the water inlet).
NOTE: When you connect the water supply hose and the drain hose, pay attention to the
indications of “Water inlet” and “Drain outlet” on the ice maker.
You must connect the drain line before using the ice maker. Follow the steps below.
Therearetwo types of ice machine modes, one that drains bygravity andone that has an internal drain pump.
or over a horizontal length of 1.5m (59”).

10
Connecting The Drain Line
NOTE: If there is a drain line near the ice maker, the best choice to drain water to the drain line, is through
the drain water hose provided with ice maker.
1. Locate the floor drain near the ice maker. The distance should be less than 5 feet since the length of the long
drain water hose provided with the ice maker is about 5 feet.
2. Find the drain outlet on the back of ice maker, take off the rear drainage plug. Connect the nut of the drain
outlet to the water draining hose, insert the other end of the hose into the drain line.
NOTE: Never allow the drain hose to hang or loop higher than the floor of the ice storage bin.
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 stand pipe with a trap below it would beacceptable for the
drain/waste receptacle. A floor drain is alsoacceptable. If this is not possible, DUURA recommends the use of a
condensate pump. Available at local hardware stores.
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.
NOTE: This ice maker is not a freezer. Hot temperatures will cause a high rate of melting in the ice
storage bin. Ice will drain over time. A drain is required.
INSTALLATION TYPES
This ice maker has been designed for Mobile (free-standing) installation. However, it can also be Enclosed (under a
cabinet) or Built-in (sealed to the floor). In every case, there must be adequate air space around the unit for ventilation.
Mobile Installation
A mobile installation will allow you to install the ice maker free-standing in any place you desire provided you have
access to a water supply, proper electrical, a drain and you’ve leveled the ice maker.
Enclosed Installation
An enclosed installation will allow you to install the ice maker under a cabinet provided the required clearance
space around the ice maker is respected, and you have access to a water supply, proper electrical, a drain and
you’ve leveled the ice maker.
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 ice maker in front of 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 must be plumbed before connecting to the ice maker.
3. The drain line must be connected. If you do not have a floor drain, you will require a condensation pump.
4. Turn on main water supply and tap. Check for water supply connection
leaks. Tighten every connection (including connection at the water inlet).
5. If the electrical outlet for the ice maker is behind the cabinet, plugin the ice maker.
6. Push the ice maker intoposition.
7. Seal all around the cabinet to the floor with an approved caulking compound.
NOTE: Be sure the drain hose isconnected and fed into the drain line before the ice maker is
moved into its final position.

1. Turn on the water tap, let the water trough fill, then press the ON/OFF button on the front panel. The ice
maker will start working automatically.
Ice Making Stage Ice Harvest Stage Bin Full Stage
2. After 3 minutes, the ice maker will automatically go to the ice-making stage, and the sound of water flowing 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 bin-full probe
open. The ice maker stops making ice automatically.
5. The unit will start making ice again after the ice cubes are removed. Then the bin-full probe swings back to
operatingposition.
6. Bin light (if present) (standard on DI50P and ): The bin light is controlled bya magnetic reed switch that has been
installed onthe inner surface of the door. Itis turned Onor Off automatically with the opening or closing ofthe
door.
7. Pump Water Drain system (if used) (standard on DI50P and ): Assoon as the icemelt water or other surplus
overflow water in the water reservoir reaches the maximum level, the water level switch closes and transmits a
low-voltage current tothe PCboard. The PC board energizes the water drain pump for 20seconds, pumping out
most of the excess water in the water reservoir.
NOTE:
• Although the unit has been tested and cleaned 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 ice maker is working.
• Never touch evaporator when unit is running!
• Except to take ice from the unit, keep the door closed to reduce melting andinsure
proper ice formation.

12
How The Ice Maker Makes Ice
Set the ON/OFF button tothe ONposition. The ice maker will automatically goto the icemaking stage.
There are two distinct cycles: ice freeze and harvest.
1. The freeze cycle happens when water flows to the evaporator surface.
2. The harvest cycle is when the ice is released and water enters the ice maker.
20 Minutes: A complete cycle takes about 20 minutes, but it depends 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 harvest cycle
begins.
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 hot refrigerant 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.
How The Ice Maker Uses The Water
The ice maker begins with a fixed charge of water that is contained in the water trough. As the water flows to the freezing
evaporator surface, the portion of water that does not contain mineral impurities freezes and sticks to the ice cube molds.
The water containing impurities falls back into the water trough. During the ice making process, fresh water enters into the
water trough continuously as the water in trough freezes continuously in the evaporator.
DI50P and DRAIN SYSTEM OPERATION
How the drain system operates when water ispumped out
The components ofthe Pump-Out Water Drain System are
•Water reservoir
•PC Board & Water level switch 1, 2
•Water Drain Pump
Drain Pump Operation
•All water coming from the overflow and the melted ice is
collected in the water reservoir.
•As soon as the water in the reservoir reaches the maximum level,
the water level switch 1 closes, transmitting a low voltage current
to the PC Board.
1- Water Inlet
2- Evaporator
3- Water Pump
4- Compressor
5- Condenser
6- Fan Motor
7- Hot Gas Value
Water Reservoir

•The PC board activates the water drain pump for 20 seconds, pumping out
most of the water contained in the water reservoir.
•The water can be pumped out up a rise of 1.5m (59”) or
over a horizontal length of 1.5m (59”).
•If water level switch 2 closes, transmitting a low-voltage current to the PC board, the PC board
activates the buzzer alarm, informing you that the drain pump, water level switch or drain tube may
be malfunctioning.
Drain System Schematic Diagram
NOTE:
The outlet of the drain hose
must be raised higher than
the water surface to prevent
the drained water from
flowing back into the water
reservoir.
WARNING!
If alarm buzzer sounds, turn
off the ice maker and the
water supply, remove all ice
from storage bin, and wipe
up any water that may have
overflowed. Check if there is
any water in water trough at
back of unit; if no water,
drainage pump may not be
receiving the proper amount
of power. Check power
source. If the problem can be
corrected, turn on the unit
again. Also check that none
of the water lines are kinked.
If the problem remains,
contact Customer Service.

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 louder than they actually are. The following list describes the sounds that might be new to
you and what may be causing them.
• Rattling noises may come from the flow of the refrigerant or the water line. Item stored
on top of the ice maker can alsomake noises.
• The high efficiency compressor may make a pulsating or high-pitched sound.
• Water running may make a splashingsound.
• 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.
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.
3. Shut off the electric supply at the main electrical powersource.
4. Take out the ice storage bin to remove any remaining ice and water. Dry thebin.
5. Pull off the drainage tube of the water trough to drain off all water.
6. Leave the door open to allow for circulation and to prevent mold and mildew.
7. Leave water supply line and power cord disconnected until ready to reuse.
NOTE: Do not touch the power plug when your hands are wet. Never unplug the unit by pulling on the cord.
Grasp the plug and pull out firmly.

CLEANING AND MAINTENANCE
CAUTION
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 solutions.
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 if 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 Parts Should Be Kept Clean?
1. The exterior
2. The interior
3. The condenser
4. Water distribution tube
5. The ice-making system
Exterior 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.
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 steel, stainless steel can discolor when exposed to chlorine gas and moisture. Clean stainless
steel with a mild detergent and warm water solution and a damp cloth. Never use an abrasive cleaning agent.
Interior Cleaning
The ice storage bin should be sanitized occasionally. Clean the water trough before the ice maker is used 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, and the ice storage bin is empty.
1. Disconnect the power to theunit.
2. Open the door and take out the removable ice storage bin. With a clean cloth, wipe down the interior of unit
and ice bin with a sanitizing solution made of 1 ounce of household bleach or chlorine and 2 gallons of hot
(95˚F – 115˚F) water.
3. Rinse thoroughly with clear water.
4. Screw off the drainage nut to draincompletely.
5. Put the ice storage bin inside theunit.
6. Reconnect power to theunit.
The ice scoop should be washed regularly. Wash it just like any other food container.
WARNING
DO NOT use solvent-based cleaning agents or abrasives on the interior.
These cleaners may transmit taste to the ice cubes and damage or discolor the interior.

16
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.
2.
Unplug the ice maker or disconnect power.
Gently pull off the lower front louver. (On DI50-O only
remove two screws securing front louver and then remove
louver.)
3. Remove dirt and lint from the condenser and the unit
compartment with the brush attachment of a vacuum cleaner.
4. Reassemble the lower front louver.
5. Plug in the ice maker or reconnectpower.
Water Distribution Tube Cleaning
Condenser
Surface
When you find the ice cubes are incompletely formed or the output is low, the water distribution tube may be blocked.
Turn off the power button, gently take out the water distribution tube, locate the holes in the distribution tube and use a
pointed object such as a toothpick to dredge the holes. Then put the water distribution tube back to its original position.
If the tube is badly blocked, clean it asfollows:
1. Shut off the water supply.
2. Disconnect the water hose from the distribution tube.
3. Gently take out the distribution tube.
4. 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 lint from the surface, rinse the tube with clean water.
5. Replace the distribution tube.
6. Reconnect the watersupply.
Ice-Making System Cleaning and Sanitizing
Minerals that are removed from the 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 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 once every 6 months.
1. Make sure that all the ice is off the evaporator. If ice is being formed, wait until the cycle is completed, then
press the ice maker’s ON/OFF switch on the control panel.
2. Remove all ice from the storage bin.
3. Keep the ice maker connected to the water supply. Pour 8 oz. of Nickel-Safe Ice Machine Cleaner Solution into
the water trough. Then press the ON/OFF switch and the CLEAN button, initiating the wash cycle. The ice
maker will run in the Automatic Clean Mode.

17
4. Allow 30 minutes for proper cleaning. After cleaning, press the ON/OFF switch again. Use a drain hose on the
front of the water trough to drain off the waste water to a convenient container. Don’t drain off the waste
water to the inside of thecabinet.
5. Repeat steps 3 and 4 (without Ice Machine Cleaning Solution) three times to rinse the ice making
system thoroughly.
6. Next, prepare a sanitizing solution made of 1 ounce of household bleach and 2 gallons of hot water (95˚ to 115˚F).
Fill a spray bottle with the sanitizing solution and spray all corners and edges, making sure to cover all surfaces
with the solution. Wipe the entire bin inside and outside, covering the entire surface of the walls. Allow the
solution to be in contact for at least 3 minutes, then dry.
7. Repeat steps 1 to 5 with the sanitizing solution of step 6 (bleach and water). Filling the water through to its
maximum level.
8. Repeat steps 3 and 4 to rinse the ice making system one moretime.
9. Press the ON/OFF button again. The ice maker will return to the regular ice making mode. Discard the first
batch of ice.
WARNING
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.
