Precaut ions for safety
Read these "Precautions for safety" carefully before starting disassembly work and do it in the proper way.
When disassembling, be sure to turn off the power. When disassembling the electrical components, check the electrical wiring diagram.
The electrical components are under high voltage by the operation of the booster capacitor.
Fully discharge the capacitor before commencing a repair work. Failure to observe this warning could result in electric shock.
When parts of refrigerant cycle is disassembled by welding, be sure to work after collecting a refrigerant, if the refrigerant isn't
collected, the unit might explode.
Be sure to collect refrigerant without spreading it in the air.
These contents are an example. Please refer to a similar part of actual unit.
