(The product under normal usage refers to the operating condition of the product started and stopped a
maximum of six times an hour, the frequency of which varies more or less depending on the model.)

Note: 1. This table shows main parts. For details, refer to the maintenance inspection contract.
2. The maintenance frequency of each part indicates a rough period required until the maintenance of
the part becomes necessary. Make use of the table for appropriate maintenance designing (e.g., the
budgeting of maintenance inspection cost).
Furthermore, the inspection and maintenance frequencies may be shorter than those specified in the
table, depending on the content of the maintenance inspection contract.
3. The product requires regular inspection if the product is used in buildings to which the Law for
Maintenance of Sanitation in Buildings applies.
4. The maintenance and replacement frequencies of each part must be shortened under tough operating
conditions (e.g., longer operating hours and highly frequent ON/OFF times) and operating
environments (e.g., environments with high-temperature, high-humidity, excessively dusty, and oily
atmospheres).
For details, contact your dealer.
