The operation time is helpful for roughly determining the time of replacement. For the replacement of parts, contact the service network or Toshiba branch office printed on the back cover of this instruction manual.
■Standard replacement cycles of principal parts
The table below provides a listing of the replacement cycles of parts when used under normal conditions (average ambient temperature: 30°C, load factor: not more than 80%, operation time: 12 hours per day). The replacement cycle of each part does not mean its service life but the number of years over which its failure rate does not increase significantly.
