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 resis-

tance 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.
