1. PRECAUTIONS (SAFETY WARNINGS)
● Unplug the appliance before replacing or repairing electrical parts.
⇒ Be careful to avoid electric shock.
● Always use only the correct replacement parts.
⇒ Check the model name, rating voltage, rating current, running temperature
symbols.
● When troubleshooting, verify that wiring harnesses are connected securely.
⇒ Make sure the connectors are not separated when power is supplied.
● Check for visible traces of water on electrical parts.
⇒ Replace or secure any part that may have come in contact with water.
● Check the status of parts after replacement or troubleshooting.
⇒ All parts must be reinstalled properly.
● Check the location where the refrigerator will be used.
⇒ If the refrigerator will be used in a damp or wet space, or if installation will be
unstable, the unit should be relocated.
● The refrigerator must be grounded properly.
⇒ An earth ground should be used if there is a risk of high humidity or wetness.

2. PRODUCT FEATURES AND SPECIFICATIONS
Product Features
Cool Select Room ▶ You can store various foods by selecting a mode from among
'Freezer,' 'Soft Freezer,' 'Chill,' and 'Cool' modes. You can set it to
be a fridge compartment if you have more foods for refrigeration
and to be a freezer compartment if you have more foods to be
frozen.
Chef Mode ▶ It controls the temperature minutely by letting the temperature
sensor inside the refrigerator sense the temperature more
frequently. It makes a fresh storage environment by minimizing
the changes of foods by temperature changes.
Chef Pantry ▶ You can store meat or fish fresh, and can store foods of size up
to a pizza box of 13" (48 cm).
Moisture Care Technology
and Triple Independent
Cooling Method
▶ It maintains the taste and flavor of foods' own by the triple
independent cooling method, which is an upgraded version of
the moisture care technology of Zipel's own, and keeps foods
fresh for a long time by maintaining the humidity inside the fridge
compartment at around 70%.

2-6. ICE-MAKER Function
- The ICE-MAKER function is an option and the following explains the function of these models.
- The ICE-MAKER is a kit that supplies water on its own, freezes water into ice and stores the ice cubes in the Ice
Container with the capability of making ice automatically without manual controlling
1) ICE-MAKER Components
2) Initial Operations
1. When the power is on, it checks the temperature of the Ice Maker Sensor. If the Ice Maker Sensor
temperature is lower than 0℃, the Ice Maker Heater will be on for 4 minutes. After that, it will run the Initial
Test Mode. If the Ice Maker Sensor temperature is higher than 0℃, it will run the Initial Test Mode right
away.
2. During the Initial Test Mode, it carries out the operation of the Ice Maker Motor and its Heater turns on for
30 seconds.
3. If the Ice Maker Sensor temperature is over 0℃ upon the initial power on, the Water Valve will work for a
second while its Heater is on.
4. The Ice Maker Motor rotates both clockwise and counter clockwise repeatedly. And, when it is sensed as
being at the parallel position (Home) within 6 minutes after the Motor starts operating, its initial operation will
stop and its normal ice making will begin.
5. When it does not sense the parallel position (Home) within 6 minutes after the Motor starts operating, it will
be considered as the Ice Maker defect and its initial operation will stop.
※ Operation upon Ice Maker Defect during the Initialization.
1) Upon the termination of the Initialization due to the Ice Maker Defect, it runs the Initialization again. And, when
the defect is detected during all the set number of times (ex. 3 times), it will stop the Initialization of the Ice Maker.
2) When it is sensed as defect 3 times in a row during the initialization, the Ice Maker does not operate for the
set duration (ex. 3 hours) and it runs the initialization again after a set time period.

PRODUCT FEATURES AND SPECIFICATIONS
3) General Operation
•
Water Supply > Stand-by Time for Ice Making > Temperature Checking for Ice Maker Sensor > Ice Removing
Water Supply Ice Making Ice Removing
1. After supplying water, it stands by for 14 minutes before starting the ice making. After that, it checks the Ice Maker
Temperature.
2. When the Ice Maker Sensor temperature is measured lower than -13℃ for more than 5 seconds, its ice making
is completed.
3. When the ice making is completed, the Ice Maker Heater and Motor operates and the ice cubes are to be
removed from the Ice Maker. At this time, its heater thaws out the outer surface of the ice cubes allowing them to
be removed from the Ice Maker easily. And, its motor turns both clockwise and counter clockwise to remove the
ice cubes from the Ice Maker.
4. The Ice Maker repeats the operation of the (1) ~ (3) until ice cubes build up in the Ice Bucket triggering the Full-
Ice Detect Sensor on. At this time, the Ice Maker stops producing ice cubes.
4) Ice Off (Stopping Ice Making) Function
1. When turning on the Ice Off function at the preference setting, the Ice Maker function will be off.
2. When the Ice Maker is off, it does not supply water to the Ice Tray.
3. When turning off the Ice Off function, the Ice Off function will be cancelled. When the Ice Off is cancelled, it starts
from ice making and the operation of the Ice Maker resumes.
5) TEST Function
- It is a function to be used when it needs the forced operation for the purpose of repairs or cleaning.
1. When pressing the Test Button for 1.5 seconds, the Test Function will start.
2. The Test Function works as follows.
Start (Alarm Sound) → Motor On (Rotating Counter Clockwise) → Motor On (Rotating Clockwise) → Heater On →
Motor On (Rotating Clockwise) → Home Location → Water Supply → Completed (Alarm Sound)
※ The Ice Maker Heater will be On / Off
The Ice Maker Heater will be On and Off according to the temperature conditions of the Ice Maker Sensor when
the Ice Maker Motor rotates clockwise.
3. When the entire operation is to be completed within 6 minutes after the motor starts operating upon pressing the
Test button, it sends out alarm sound. And, after this, it does normal ice making.
4. When the entire operation does not complete normally (ex. Not reaching at the Home location) within 6 minutes
after the motor starts operating upon pressing the Test button, it will be considered as the Ice Maker defect and
the entire loads (Motor, Heater, etc) will be off. (No alarm sound)
After this, it performs an operation checking whether the Ice Maker operates normally according to the set time
cycle (ex. 3 hour).

DISASSEMBLY AND REASSEMBLY
3-1. Precautions
• Before replacing or repairing an electrical part, be sure to unplug the product's power cord.
- Failing to do so may result in electric shock.
• Be sure to replace any electrical parts with rated parts.
- Be sure to check the model no, rated power voltage, operating temperature etc. printed on the product.
• When repairing a product, connect the harnesses firmly so that no water enters the product.
- They should not become separated if a certain amount of force is applied.
• When repairing the product, completely remove all dust or foreign substances from the housing, connectors and
terminals.
- Prevents fire due to tracking or short-circuits.
• Check if there are any marks of moisture having entered the electric parts.
- If it appears that moisture has penetrated the part, take countermeasures such as replacing the part or wrapping
the part with insulation tape.
• After fixing a problem, check the assembly status of the parts.
- The status must be the same as before repairing the product.
• Check the operating environment of the refrigerator.
- If the refrigerator is exposed to moisture or is installed near water or on an unstable surface, relocate the
refrigerator.
• Ground the refrigerator if necessary.
- In particular, if there is a danger of electric leakage due to moisture or water, be sure to ground the refrigerator.
• Do not share a power strip with other appliances.
• Check if the power plug or electrical outlet is damaged, deformed or old.
- If the power plug or outlet is damaged or out of order, repair it immediately.
- Take care when you move the product so that the power cord is not damaged, cut or becomes trapped.
• Do not store food in an unstable manner in the refrigerator or store bottles in the freezer.
• Do not let customers repair the product by themselves.
• Do not let customers store items other than food in the refrigerator.
- Medicine or chemicals: A precise temperature cannot be maintained by the refrigerator for home use.
- Inflammable materials (alcohol, benzene, ether, LP gas, butane gas, etc.): There is a danger of explosion.
