1. Precautions
Samsung Electronics 1-1
1. Warning: Prior to repair, disconnect the
power cord from the circuit breaker.
2. Use proper parts: Use only exact
replacement parts. (Also, we recommend
replacing parts rather than repairing them.)
3. Use the proper tools: Use the proper tools
and test equipment, and know how to use
equipment may cause problems later-
intermittent contact, for example.
4. Power Cord: Prior to repair, check the
power cord and replace it if necessary.
5. Avoid using an extension cord, and avoid
tapping into a power cord. This practice
may result in malfunction or fire.
6. After completing repairs and reassembly,
check the insulation resistance, Procedure:
Prior to applying power, measure the
resistance between the power cord and the
ground terminal. The resistance must be
greater than 30 megohms.
7. Make sure that the grounds are adequate.
8. Make sure that the installation conditions
are satisfactory. Relocate the unit if
necessary.
9. Keep children away from the unit while it is
being repaired.
10. Be sure to clean the unit and its surrounding
area.
Fig. 1-1 Avoid Dangerous Contact
Fig. 1-2 No Tapping and No Extension Cords

1. Replacing the compressor - Do not fill the system with oil as the compressor is already charged.
2. Replacing the condenser - Refill 50cc.
3. Replacing the evaporator - Refill 50cc.
4. Replacing the refrigerant - Refill 30cc.
5. The high pressure side is filled up with oil after the vacuum is completed.
6. When the refrigerant leaks, it is generally not necessary to refill the oil if the leakage is not severe.
