1. Warning: Prior to repair, disconnect the
power cord from the circuit breaker.
2. Use proper parts: Use only exact replace-
ment 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 equip-
ment 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, mea-
sure 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 surround-
ing area.
