Precautions - Samsung MC18AC2-09 Service Manual

1. Precautions

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 them.
Using defective tools or test 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 tap-
ping 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 megaohms.
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.
