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 during 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 power 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 electric shock.
4.If the wall outlet is over loaded, it may cause fire. Please
use its own individual electrical outlet for the refrigerator.
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 icemaker 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.
5.Please make sure the outlet is properly earthed, particularly in wet or damp area.
6.Use standard electrical components when replacing them.
7.Make sure the hook is correctly engaged.
Remove dust and foreign materials from the housing and connecting parts.
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.

HOW TO INSTALL REFRIGERATOR
2. How to Install Water Pipe |
2-1. When connecting directly to the water tap. |
|||
Before Installation |
|
Please confirm the following installation parts. |
||
1. The icemaker requires the water pressure of 1.5 |
|
|
|
|
8.5kgf/cm2. (It is acceptable if city water fills a cup of |
|
|
||
180cc with water for 3 seconds) |
|
|
|
|
2. Install booster pump where the city water pressure is |
|
|
||
below 1.5kgf/cm2 for normal operation of water and ice |
|
|
||
dispenser. |
|
Valve Feed |
Rubber, Packing |
Connector, Pipe |
|
|
|||
3. The total length of water pipe shall be less than 12m. Do |
|
|
||
not bend the pipe at right angle. If the length is more |
|
|
||
than 12m, there will be troubles on water supply due to |
|
|
||
water pressure drop. |
|
|
|
|
4. Please install water pipe where there is no heat around. |
