WARNINGS AND PRECAUTIONS FOR SAFETY

Please observe the following safety precautions in order to

use safely and correctly the refrigerator and to prevent

accident and danger dudng repair.

1. Be care of an electric shock. Disconnect power cord

from wall outlet and wait for more than three minutes

before replacing PWB parts. Shut off the bower

whenever replacing and repairing electric components.

2. When connecting power cord, please wait for more than

five minutes after power cord was disconnected from the

wall outlet.

3. Please check if the power plug is pressed down by the

refrigerator against the wall. If the power plug was

damaged, it may cause fire or electde shock.

4. Ifthe wall outlet is over loaded, it may cause fire. Please

use its own individual electrical outlet for the refrigerator.

5. Please make sure the outlet is properly earthed,

parficulady in wet or damp area.

6. Use standard electrical components when replacing

them.

7. Makesure the hook is correctlyengaged.

Remove dust and fore=gnmaterials from the housing

and connecting parts.

8. Do not fray, damage, machine, heavily bend, pull out,

or twist the power cord.

9. Please check the evidence of moisture intrusion in the

electrical components. Replace the parts or mask it

with insulation tapes if moisture intrusion was

confirmed.

10. Do not touch the icamaker with hands or tools to

confirm the operation of geared motor,

11. Do not let the customers repair, disassemble, and

reconstruct the refrigerator for themselves. It may

cause accident, electric shock, or fire.

12. Do not store flammable materials such as ether,

benzene, alcohol, chemicals, gas, or medicine in the

refrigerator.

13. Do not put flower vase, cup, cosmetics, chemicals.

etc., or container with full of water on the top of the

refrigerator.

14. Do not put glass bottles with full of water into the

freezer. The contents shall freeze and break the glass

bottles.

15. When you scrap the refrigerator, please disconnect the

door gasket first and scrap it where children are not

accessible.

Causes

Refrigerant leak.

Shortage of refrigerant.

Check seouence

1. Check the welded parts of the

dner inlet and outl_ and dder

auxiliary in the compressor

compartment (high pressure side).

2. Check the end of compressor

sealing pipe (low pressure side).

3. Check silver soldered parts.

(Cu + Fe /Fe ÷Fe).

4. Check bending area of wire

condenser pipe in compressor

compartment (cracks can

happen during bending).

5. Check other parts (compressor

compartment and evaporators in

freezer compartment).

Check frost formation on the surface

of evaporator in the freezer

compartment.

- If the frost forms evenly on the

surface, it is OK.

- If it does not, it is not good.

Measures

Weld the leaking part, recharge the

refrigerant.

-Find out the leaking area, repair,

evacuate, and recharge the

refrigerant.

i" NO leaking, remove the remaining

refrigerant, end recharge new

inserting into the evaporator.

2) Lead wire of heater is cut.

3) Heating wire at lead wire contacts

is cut.

2. Ice.

Gap between Sucking duct and

Heater plate(Ice in the gap).

Wrong heater rating (or wrong

assembly),

1, Check the resistance of heater.

O_;_:Short. _: Cut.

Tens to thousands _: OK,

2. Check the resistance between

housing terminal and heater

surface.

OQ: Short, o=Q:Cut.

Tens to thousands _]: Short.

1. Confirm foreign materials. In case

of ice, insert the copper line

through the hole to check,

2. Put hot water into the drain

(check drains outside).

1. Confirm in the Sucking duct.

1. Check heater label,
