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.
