SAFETY DURING REPAIR WORK
First, I must disconnect
the power cord plug
from the power outlet.
1. In order to disassemble and repair the unit
in question, be sure to disconnect the power
cord plug from the power outlet before
starting the work.
2. If it is necessary to replace any parts, they should be replaced with respective genuine parts for the unit, and
the replacement must be effected in correct manner according to the instructions in the Service Manual of the
unit.
If the contacts of electrical
parts are defective, replace the
electrical parts without trying to
repair them.
3. After completion of repairs, the initial state should
be restored.
4. Lead wires should be connected and laid as in the
initial state.
5. Modification of the unit by user himself should
absolutely be prohibited.
6. Tools and measuring instruments for use in repairs or inspection should be accurately calibrated in advance.
7. In installing the unit having been repaired, be careful to prevent the occurence of any accident such as
electrical shock, leak of current, or bodily injury due to the drop of any part.
8. To check the insulation of the unit, measure the insulation resistance between the power cord plug and grounding
terminal of the unit. The insulation resistance should be 1M or more as measured by a 500V DC megger.
9. The initial location of installation such as window, floor or the other should be checked for being and safe
enough to support the repaired unit again.
If it is found not so strong and safe, the unit should be installed at the initial location reinforced or at a new
location.
10. Any inflammable thing should never be
placed about the location of installation.
11. Check the grounding to see whether it is
proper or not, and if it is found improper,
connect the grounding terminal to the earth.
