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.
