Operating Method
1.
Switch on the Power switch on the
front 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 with ice cubes, the ice maker
will automatically stop working. The
machine will restart making ice once
the storage bin is less than full.
NOTE:
- Although the unit has been tested at 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.
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
evaporator surface gets to the setting temperature, the ice maker stops the freeze
cycle and begins the harvest, approximately 20 minutes.
Harvest: During the harvest cycle; the compressor is still operating, the water
pump has stopped and the hot gas valve and water inlet valve are energized. The
17
hot gas valve and water inlet valve open to warm up the freezing surface, allowing
the cubes to fall into the bin. Once completed, the freeze cycle begins repeatedly
until the ice has satisfied the maximum level in the bin, then the water and
compressor are shut down until sufficient ice is drawn below the bin level sensor
and the cycle again resumes.
How the machine uses water
The ice maker begins
with a fixed charge of
water that is contained
in the water bin. 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 bin. Gradually, during the freezing portion of
the ice-making cycle, the water in the water bin will become highly concentrated
with mineral impurities.
During the harvest cycle, the fresh water flows into the machine to dilute the bin
water, and to 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, walls and cabinets 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
bin 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.
18
•
•
•
•
•
•
The high-efficiency compressor may make a pulsating or high-pitched sound.
Water running from the water bin to the evaporator plate may make a
splashing 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 through 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 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 an extended period of time, or is to be moved
to another location, it will be necessary to drain the water from system.
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.
CLEANING AND MAINTENANCE
If the ice maker is left unused for an extended period, 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.
19
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’s cleaning).
Exterior Cleaning
The door and cabinet may be cleaned with a mild detergent and warm water
solution such as 1oz (29ml) of dishwashing liquid mixed with 2 gallons (7.5L) 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.
Stainless steel models can discolor when exposed to chlorine and/or chlorine gas
and should be thouroughly rinsed clean. Clean stainless steel models with a mild
detergent and warm water solution and a damp cloth. Never use abrasive cleaning
agents.
NOTICE: Stainless steel models exposed to chlorine and/or chlorine gas and moisture, such as
areas with spas or swimming pools, may show some discoloration of the stainless steel. This is a
normal condition.
20
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 three months.
1. Unplug the ice maker or disconnect power.
2. Unscrew the screws on the front cover.
3. Grasp the underpart of the right and left side, rise a little, and then pull down.
Notice: Don’t overexert the panel removal, the leads connected to the power switch can be
damaged or torn from the switch.
4. Locate the 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 icemaker or reconnect
power.
Condenser
Surface
DO NOT touch the conderser fins. The condenser fins are sharp and can be
easily damaged.
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 1oz (29.5ml) of household bleach or chlorine
and 2 gallons (7.5L) of hot water 95ºF (35°C) to 115ºF (46°C).
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.
21
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.
SPRINKLE HEAD CLEANING
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.
2. Take out the row of flake covers.
3. Find the sprinkler and the slideway.
22
4. Find which water sector is not spraying correctly from the nozzle. If the
slideway is the issue, adjust the position of slideway to have all the water
sectors free forward to the ice mold. If the water sectors are free, but some
sectors is not spraying properly, using a new tooth-brush, clean the gap of the
nozzle several times. The water sector should work normally.
5. Another cleaning method; remove the slideway from the water bin.
6. Find the sprinkler arm and raise it. Disconnect it from any water tube.
7. A de-scaling solution can be prepared in a plastic basin with a Nickel-Safe Ice
Machine Cleaner. Mix 4oz (118ml) of the ice machine cleaner per 1 gallon
(3.7L) of warm water.
8. Remove the sprinkler arm from the interior. Thoroughly clean the sprinkler
arm by soaking it in the basin filled with the de-scaling solution until it is free
of any deposit; use a soft brush to remove any thick or stubborn residue and to
help the dissolving action. Rinse under a stream of tap water.
9. Wipe down the interior of the water bin with the de-scaling solution and warm
water. Rinse thoroughly with clear water.
23
10. Reassembly the sprinkler arm, slideway and the flake covers.
11. After the Icemaker 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. 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 3 to 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. Remove the screws in the front cover,
and push forward to remove. Put the front cover against the right side
cover.
Notice: Don’t overexert, or the leads connected with the power switch can become disconnected.
3. Locate
box.
the
control
4. Turn on the power to the ice maker. Pour 8oz. (237ml) of Nickel-Safe Ice
Maker Cleaning Solution into the water bin. Add 8oz. (237ml) of tap
water. After about 5 minutes, depress the "clean" button on the Control
Box. (See figure below and following section.) The machine will run the
24
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. Drain off the waste
water to some container, and then screw the nut on tightly when the waste
water is fully drained off.
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 bin during the rinse is
not needed.
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.
7. Prepare a sanitizing solution made of 1oz (29ml) of household bleach and
2 gallons (7.5L) of hot water 95ºF (35°C) to 115ºF (46°C). Remove the
flake covers and slideway from the water bin and wipe the entire bin
inside and out, covering all surfaces.
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
cover 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, and 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. The machine will return to the normal ice making
operation. Discard the first batch of ice.
Control Box (See diagram on page 30.)
Instructions for LEDs and buttons:
1. RED LED: Ice full indicator light.
When this LED is lit, the ice storage bin is full of ice and the unit will stop
working. When ice cubes are taken out of the ice storage bin, clearing the
sensor, the red LED will flash for 3 minutes. Then the unit will restart and
return to the ice making mode.
25
2. GREEN LED: Ice making indicator light.
When this LED is lit (solid), 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.
3. YELLOW LED: Ice harvest indicator light.
When this LED is lit (solid), 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, it 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 ADJUSTMENT: 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 counter-clockwise, and the ice size will be smaller in the
next cycle.
NOTE: It is not a good idea to adjust the ice size often or for no good reason, because the
controller may damaged.
7. If the red, green and yellow LEDs are flashing together, the machine is not
working. Call for service.
NOTE: Avoid letting water contact the control box.
