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.
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 the 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 occurrence 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
1
MΩ or more as measured by a
500
V DC megger
.9.The initial location of installation such as window, floor or the other should be checked for being 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 after reinforced or at a new location.
10.
Any inflammable object must not 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.
SAFETY DURING REPAIR WORK
from the power outlet.
If the contacts of electrical parts are
without trying to repair them.
DANGER
defective, replace the electrical parts
First, I must disconnect
the power cord plug
