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 PCB 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.
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.
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.
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

Filling the water tank
Turn the small cap anticlockwise then remove it from the water tank. Fill drinking water into the
water tank through the hole.

8
•Do not fill above the level, otherwise, it may overflow.
•Before filling with water, ensure that the water tank is steady and in a correct position.
•Apart from drinking water, other beverages (such as milk, juice, carbonated beverage, etc)
are not suggested to be used, especially beverages that include grain must not be used
(may result in blockage and damage).
•Hot water must not be filled into the water tank directly.
•Do not touch other parts of the unit when filling water, it may lead to leakage.
Receiving water from the water dispenser
•You should use the type of container that can fit
under the water dispenser. Place the container
properly underneath and push on the lever for water to flow.
•Before you dispense the water, make sure the lock device is at “Unlock”position.
Ensure to slide to “Lock”position after each use to prevent children from playing with the lever.
•When at “Lock”position, do not push on the lever with force. It will damage the mechanism.
Checking the Compressor
Use a multi-meter to test the resistance between C & M, C&S and S&M :
Normal range of C&M :About 10-21Ω

9
Normal range of C&S :About 10-27Ω
Normal range of S&M : About 20-50Ω
If the test result is not in this range then it means the inner coil has some problem and the compressor
can not work properly.
Compressor Protector test ——
Use a multi-meter to test the resistance between the two end as the pic show :
If there show 000 or almost 0 then it is OK.
If there is no response then it is broken.
Compressor PTC starter test ——
Use a multi-meter to test the resistance between the two end as the pic show :
If there show the number is betweenAbout 9-25Ωthen it is OK.
If there show 000 or no response then it is broken.
