OPERATING METHOD

1. Turn on the water tap; water enters the water tank. Then turn on the power switch; the red indicator LED of the power switch lights.
2. After 3 minutes, the ice maker will automatically proceed to the ice-making stage and the sound of flowing water will be heard.
3. When a batch of ice has been fully formed, it will be harvested into the ice storage bin automatically.
4. When the ice storage bin is full, the sheet of cubes will not fall completely and the water curtain opens, the microswitch will be kept open. The machine is in the Bin Full stage.
5. The unit will start making ice again after ice cubes are removed. At the same time, water curtain swings back to hold microswitch be in operating position.

IMPORTANT:

• 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 the evaporator when the machine is running.
• Except to take ice from the unit, keep the door closed to reduce melting and insure proper ice formation.

HOW THE MACHINE MAKES ICE
Turn the power switch to the ON position. After about 3 minutes the machine will automatically go into the ice-making stage. There are two distinct cycles: freeze and harvest. During the freeze cycle, water flows to the evaporator surface. In the harvest cycle, the ice is released and water enters the machine. A complete cycle (freeze cycle and harvest cycle) takes 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 pumping water. When the batch of ice has been fully formed, the ice maker stops the freeze cycle and the harvest cycle start.

Harvest : During the harvest cycle, the compressor is still operating and power is supplied to the hot gas valve. Every 20 cycles, the water purge valve opens and allows the water pump to purge the water from the water tank, removing all impurities and sediment. This allows the machine to make clear ice cubes and keep mineral build-up at a minimum. Then the water pump stopped. When the hot gas valve opens, it allows hot gas to go directly to the evaporator. The gas warms the evaporator, causing the cubes to slide off the evaporator and into the storage bin. The freeze cycle will restart when all the cubes drop into the bin.

HOW THE MACHINE USES WATER:
The ice maker begins with a fixed charge of water that is contained in the water tank. As the water flows to the freezing evaporator surface, the water freezes and sticks to the ice cube molds. During the ice-making process, fresh water enters the water tank continuously as the water from the tank freezes continuously on the evaporator.

NORMAL SOUNDS
Your new ice cube machine may make sounds that are unfamiliar to you. Most of the new sounds are normal. Hard surfaces like the floor and walls can amplify the sounds. The following describes the kinds of 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 cube machine can also make noises.
• The high-efficiency compressor may make a pulsating or high-pitched sound.
• Running water 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 CUBE MACHINE FOR LONG STORAGE
If the ice maker will not be used for a long time, or it is to be moved to another place, it will be necessary to drain water from the system.

1. Shut off the water supply at the main water source.
2. Disconnect the water supply pipe from the water inlet.
3. Depress the clean button and hold over six seconds, the machine will go into the draining mode automatically, with harvest and ice-making indicators blinking, till the water flush down the drain completely. then the harvest indicator and ice-making indicator LEDs will be on. And the drain process complete.
4. Shut off the power supply at the main electrical power source.
5. Dry the water tank.
6. Remove all ice cubes from the ice storage bin and dry it.
7. Keep the door opening to allow for ventilation and to prevent mold and mildew.
8. Leave the water supply pipe and power cord disconnected until ready to reuse

IMPORTANT:

• Do not touch the power plug when your hands are wet.
• Never unplug the unit by pulling on the cord.

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 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 there are other special considerations.

WHAT SHOULDN’T BE DONE
Never keep anything in the ice storage bin other than 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 interior
3. Water distribution tube
4. The ice-making system cleaning

WARNING
Before proceeding with cleaning and maintenance operations, make sure the power line of the unit is disconnected and the water line is shot off. (EXCEPTION: Cleaning of ice-making system)

EXTERIOR CLEANING
The exterior of the ice maker and bin may be cleaned with a soft cloth or sponge dampened with a mild detergent and warm water solution such as 1 oz of dishwashing liquid mixed with 2 gallons of warm water. Never use solvent-based or abrasive cleaning agents. Rinse with clean water. Wipe with a soft clean towel to prevent water spotting.

INTERIOR CLEANING
Clean the water tank 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 tank after the ice-making system has been cleaned and the ice storage bin is empty. The ice storage bin should be sanitized occasionally.

Follow these steps to clean the tank and the bin:

1. Disconnect power to the unit.
2. Remove ice machine front panel.
3. Using a sanitizing solution made of 1 ounce of household bleach and 2 gallons of hot water (95º to 115ºF), wipe down the water tank and the inside of the ice storage bin with a clean cloth. To clean hard-to-reach corners, apply the sanitizing solution with a spray bottle.
4. Rinse thoroughly with clear water. This completes the interior cleaning of the ice maker and storage bin.
5. Reconnect power to the unit.

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.

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 power switch to OFF. Unscrew the six screws holding the top panel and remove the panel. You will see the water distribution tube. Rotate the water distribution tube so that the holes in it are facing up. 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 and power supplies.
2. Disconnect the water hose from the distribution tube.
3. Lift one side, remove 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 water supply and power supply lines.
7. Re-attach the top and front panels

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 on how hard your water is or how effective your filtration may be. With hard water of 15 to 20 grains/ gallon (4 to 5 grains/liter), you may need to clean the system as often as every 3 months.

1. Remove ice machine front panel.

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 8 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. The ice-making system cleaning cycle will continue for 30 minutes unless you press the power switch (you can press the power switch to stop the cleaning cycle any time during the 30 minutes). After cleaning, the harvest indicator and ice-making indicator LEDs will be on. The cleaning process stops.

7. Repeat steps 4 to 5 above three times to rinse the ice-making system thoroughly. This will complete ice-making system cleaning.
   ( NOTE : Do not add Ice Maker Cleaner Solution to the water tank during the rinses.)

8. Perform steps 3 and 4 in the Interior Cleaning section.

9. If you want to make ice cubes after cleaning, turn off the power switch, then turn on the power switch. The next ice-making cycle will begin.

10. 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.

CONDENSER CLEANING
