DISASSEMBLY FOR REPAIR
Beware of condensation
When water vapor comes into contact with the surface of cold
material, water drops are produced.
If condensation occurs, correct operation may not be possible, or
the unit may not function correctly.
This is not a malfunction, however, the unit should be dried.
To do this, turn the ON/STANDBY switch ON and leave the unit
as it is for several hours.
