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,
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 dedicated
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

completely unobstructed.
When installing the ice maker under a counter, follow the recommended spacing
dimensions shown. Allow at least 4" (102 mm) clearance at rear, and 1"(25 mm)at top
and sides for proper air circulation. The installation should allow the ice maker to be
pulled forward for servicing if necessary.
Choose a well ventilated area with temperatures above 50°F (10°C) and below 100°F
(38°C).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 high heat sources.
Installation of the ice maker requires a cold water supply inlet of ¼-in. (6.35mm) soft
copper tubing with a shut-off valve.
The ice maker requires a continuous water supply with a minimum pressure of 15 psig
and a static pressure not to exceed 80 psig. The temperature of the water feeding into
the ice maker should be between 41°F (5°C) and 90°F (32°C) for proper operation.
7
Normal operating ambient temperature should be between 50°F (10°C) to
100°F (38°C). Normal operating water temperature should be between 41°F
(5°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.
 The ice maker must be installed with all electrical and water connections in accordance
with all 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 caster. See the “Leveling the Ice Maker” section.
 A standard electrical supply, properly grounded in accordance with the National
Electrical Code and local codes and ordinances, is required.
NOTE: Do not kink or pinch the power supply cord between the icemaker and wall or cabinet.

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 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) is spec’d at 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.
Leveling the ice maker
It is important for the ice maker to be leveled in
order to wok properly. Otherwise water will not flow
properly through the evaporator (ice mold). The
ice production will be less than normal, and may
be noisy. The unit 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.
down
up
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 to the right to lower that side of the ice maker.
Turn the leveling casters to the left to raise that side of the ice maker.
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.
NOTE: When the ice maker is ready to be installed 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.

Water Supply
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 machine will make installation easier.)
NOTE:
1.
All installations must be in accordance with local plumbing code requirements. Professional installation is
recommended.
2.
Make certain the hoses are not pinched or kinked or damaged during installation.
3.
Check for leaks after connection.
Tools required:
½-in. 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 of
water.
2. Find a ½-in. to ¾-in. 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 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 with wrench.
5. Turn on 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 machine.
Drain
You must connect the drain line before using the ice maker. (The Dual Drainage feature of
earlier models has been modified to simplify the drainage procedure.) Follow the steps
outlined below.
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
11
into the drain line.
NOTE: Never allow the drain hose to hang or loop higher than the floor of the ice storage bin.
3. Screw off the water drainage nut and pull off the plug on the rear of the ice storage bin.
NOTE: Store the drainage nuts and plugs in the compartment labeled Nut/Plug Storage at the back of the unit
or in another safe place.
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 be acceptable for the drain/waste receptacle. A floor
drain is also acceptable. If this is not possible, Maxx Ice recommends the use of a
condensate pump. Contact Asbury Service Warranty & Parts at 1-877-368-2797.
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.
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. You must follow the stated instructions
for:
a. Electrical requirements
b. Water supply
c. Leveling the ice maker.
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.
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. Turn on main water supply and tap. Check for water supply connection leaks. Tighten
12
every connection (including connection at the water inlet).
4. If the electrical outlet for the ice maker is behind the cabinet, plug in the ice maker.
5. Push the ice maker into position.
6. Seal all around the cabinet to the floor with an approved caulking compound.
NOTE: Be sure the drain hose is connected 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
13 stage
Bin full stage
2. After 3 minutes, the machine 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 machine automatically stops making ice and
progresses to the cold preservation stage. During this stage, the compressor works
regularly to keep the temperature low for less ice melting.
5. The unit will start making ice again after the ice cubes are removed. Then the bin-full
probe swings back to operating position.
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 and insure proper ice formation.
Theory of Operation
Set the ON/OFF button to the ON position. The machine will automatically go to the ice
making stage.
There are two distinct cycles: ice freeze and harvest.
The freeze cycle happens when water flows to the evaporator surface. The harvest cycle is
when the ice is released and water enters the machine. 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 machine 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
14
enters into the water trough continuously as the water in trough freezes continuously in the
evaporator.

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. Items

stored on top of the ice maker can also make noises.
The high efficiency compressor may make a pulsating or high-pitched sound.
Water running may make a splashing sound.
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.
3.

5.
6.
7.
Disconnect the water supply line from the water inlet.
Shut off the electric supply at the main electrical power source.
Take out the ice storage bin to remove any remaining ice and water. Dry the bin.
Pull off the drainage tube of the water trough to drain off all water.
Leave the door open to allow for circulation and to prevent mold and mildew.
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
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 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
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
Before proceeding with cleaning and maintenance operations,
make sure the power line of the unit is disconnected and the
water line is shut off.
Exterior cleaning
Commercial grades of stainless steel are susceptible to rusting if not properly maintained. It is important that
you properly care for the stainless steel surfaces of your ice machine and bin to avoid the possibility of rust or
corrosion. Use the following recommended guidelines for keeping your stainless steel looking like new:
1. Clean the stainless steel thoroughly once a week. Clean frequently to avoid build-up of
17
hard, stubborn stains. Also, hard water stains left to sit can weaken the steel's corrosion
resistance and lead to rust. Use a nonabrasive cloth or sponge, working with, not across,
the grain.
2. Don't use abrasive tools to clean the steel surface. Do not use steel wool, abrasive sponge pads, wire brushes
or scrapers to clean the steel. Such tools can break through the "passivation" layer - the thin layer on the
surface of stainless steel that protects it from corrosion.
3. Don't use cleaners that use chlorine or chlorides. Don't use chlorine bleach or products like Comet to clean the
steel. Chlorides can also break down the surface layer and can cause rusting.
4. Rinse with clean water. If chlorinated cleansers are used, you must thoroughly rinse the surface with clean
water and wipe dry immediately.
5. Use the correct cleaning agent. The table below lists the recommended cleaning agents
for common stainless steel cleaning problems:
Cleaning Activity
Cleaning Agent
Method of Application

Interior cleaning
It is the USER’S RESPONSIBILITY to see that the unit is properly maintained. It is always
preferable and less costly in the long run, to avoid possible down time by keeping it clean and
adjusted as needed; and by replacing worn components before they can cause failure. The
following is a list of recommended maintenance that will help keep the machine running with a
minimum of problems.
Maintenance and Cleaning should be scheduled at a minimum of twice per year.
Note: Electrical power will be ON when performing the following cleaning instructions.
1. Remove ice machine front panel.
18
2. Make sure all ice is off evaporator. If ice is being made, initiate harvest or wait for cycle
completion, then turn machine off at the power switch.
3. Remove all ice cubes from the storage bin.
4. Keep the ice maker connected to the water supply. Pour 4 oz. of Nickel-Safe Ice Maker
Cleaner Solution into the water tank.
5. Turn on the power switch. Within 3 minutes press the Clean button. The machine will
go into the cleaning mode automatically.
6. Allow 30 minutes for proper cleaning. After cleaning, press the machine “ON/OFF”.
Drain off the waste water to another container by drain pipe in the front of the water
trough. You will note that the water will continue to fill the sump. Squeeze the hose
and put back into place so that the sump remains full of clean water. Note: Don’t drain
off the waste water to the inside of the cabinet.
7. Inspect the evaporator and water spillway to ensure all mineral residue has been removed.
If necessary, wipe the evaporator, spillway and other water transport surfaces with a clean
soft cloth to remove any remaining residue. Reassemble all components and repeat steps 4
through 7 as required to remove residue
8. Repeat step 5-6 above three times to rinse the ice-making system thoroughly. This will
complete ice-making system cleaning. Turn the incoming water supply off and drain out
the sump as indicated in step 6.
9. Prepare 1½ to 2 gallons (5.7 to 7.5 liters) of approved (EPA/FDA) sodium hypochlorite
food equipment sanitizer to form a solution with 100 to 200 max. ppm free chlorine yield.
10. Add enough sanitizing solution to fill the water trough to overflowing and begin the
cleaning cycle as indicated in 5, and allow circulation to occur for 5 minutes and inspect all
disassembled fittings for leaks. During this time, wipe down all other ice machine splash areas,
plus the interior surfaces of the bin, deflector and door with the remaining sanitizing solution.
Inspect to insure that all functional parts, fasteners, thermostat bulbs (if used), etc. are in the
correct position.
11. After sanitizing, press the machine “ON/OFF”. Drain off the waste water to another
container by drain pipe in the front of the water trough. Turn on the water and you will
note that the water will fill the sump. Squeeze the hose and put back into place so that
the sump remains full of clean water. Note: Don’t drain off the waste water to the inside
of the cabinet. Do not mix the sanitizer and the cleaner together, fumes could arise.
19
12. Repeat step 5-6 above with clean water to rinse the ice-making system thoroughly.
Drain the water as indicated in Step 11. This will complete ice-making system
cleaning. Then press the controller to “OFF”
13. Turn the machine ON and replace the front panel.
14. Discard the first two ice harvests. DO NOT USE any ice produced from the cleaning
solution.
Bin 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 the unit.
2. Open the door, 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 (95ºF --115ºF) water.
3. Rinse thoroughly with clear water.
4. Screw off the drainage nut to drain completely.
5. Put the ice storage bin inside the unit.
6. Reconnect power to the unit.
The ice scoop should be washed regularly, wash it just like any other food containers.
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.
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. Gently pull off the lower front grille.
3. Locate the condenser filter. This can be lifted out and
Condenser
surface
cleaned with a brush or flowing water.
4. Remove dirt and lint from the condenser fins and the unit
compartment with the brush attachment of a vacuum cleaner.
5. Put back the filter and reassemble the front lower grille.
20
6. Plug in the ice maker or reconnect power.
DO NOT touch the condenser fins. They are sharp and can be easily damaged.
Water distribution tube cleaning
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, rotate 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 rotate the water distribution tube back to its original position. If
the tube is badly blocked, clean it as follows:
1.
2.
3.
4.
Shut off the water supply
Disconnect the water hose from the distribution tube.
Lift the right side up, then remove the distribution tube.
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 water supply.
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.

Description of LEDs and buttons:
1. Bin Full (Red) LED: Bin full indicator light
When this is lit, the ice storage bin is full of ice or there is some thing blocking the
bin-full probe. The unit will stop working. When ice cubes are removed from the ice
storage bin, freeing the bin-full probe, the red LED will remain 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 is lit, the unit is working in the ice making mode controlled by a
temperature probe on the evaporator. When the green LED flashes, the unit is working
in the ice making mode controlled by a fixed timer.
3. Ice Harvest (Yellow) LED: Ice harvest indicator light
When this is lit, the unit is working in the ice harvest mode controlled by the ice-full
probe.
When both the green and yellow LEDs are lit, the unit is in the cold preservation
mode.
4. Mode button: Mainly for service. When this is pressed, the ice making mode changes
to ice harvest mode or vice versa. The mode can be judged from the status of the green
and yellow LEDs.
MAJOR FUNCTIONS
1. The operating procedure is completely automatic.
2. When the ice storage bin is full of ice cubes,the machine stops making ice and
proceeds to the cold preservation stage automatically. It starts making ice again after
ice cubes are removed.
3. The different colors of the LED display indicate various work modes.
4. The fan motor responds to the ambient temperature. If it is cold, the motor will stop
working to keep the cooling system in good working condition.
5. A sensitive probe and accurate timer enhance the performance of the ice maker.
6. A compressor protection system is built in.
