equipment.
Recommended Design Life
It is recommended that this product be used within the
recommended design life.
The recommended design life is the period during which
you can use the product safely and reliably based on
the design specications.
If the product is used beyond this period, its failure ratio
may increase due to time-related deterioration of parts,
etc.
The recommended design life during which the product
can operate reliably with the lowest failure ratio and
least deterioration over time is estimated scientically
based on acceleration tests, endurance tests, etc.,
taking into consideration the operating environment,
conditions, and frequency of use as basic parameters.
The recommended design life of this product is 10
years.
The recommended design life assumes that mainte-
nance, such as replacement of the limited life parts, is
carried out properly.
Refer to the section on maintenance in this manual.
