1. SAFETY AND PRECAUTIONS

1) For starters, be sure to check any chances of the leakage of electricity.

2) You could handle a part in the vicinity of electricity after unplugging.

3) You should put on rubber glovers to prevent an electric shock on operation test.

4) Make sure the rated current, voltage, capacity before using an instrument.

5) Keep your wet hands away from the metal goods in the freezer compartment

not to be frostbitten.

6) Be careful not to let water to permeate the electric part in the machine room.

7) With the door open during your working, you might be damaged by door.

8) You should give a tilt to the refrigerator for your safe after removing the

breakable goods inside the refrigerator.

9) You'd better use cotton gloves if you fix it up around the evaporator.

4. TROUBLE SHOOTING GUIDE

4-1. CYCLE REPAIR FLOW CHART

11

Yes

Service Call

Is there any problem with your cycle? General repair

Gas leakage Inferior compressor Cycle clogging Incomplete vacuum

Lack of refrigerant, etc.

Replace your

refrigerant.

Replace dryer.

Vacuumize cycle.

Check if vacuum is complete.

Check if leakage happens or not.

Anti-corrosive paint treatment.

Cooling test.

Check if leakage happens or not at the choked point.

END

Choke tightly the entrance of refrigerant.

Charge refrigerant.

Cut the dryer.

Check if the viscous oil is

Attached or not around that part.

And check if the entrance of capillary

tube is clogged or not.

Only if that number is less

than “4”, the viscous oil is

not generated.

The viscous oil is generated

only if the result number is

more than “5”.

Get the oil out of the compressor.

Compare the ASTM standard

color with this oil color.

Replace only compressor with

making sure to blow nitrogen into it.

No
