Appendix Handling Replaceable Components - Hitachi HF-W2000 Instruction Manual

APPENDIX HANDLING REPLACEABLE COMPONENTS

Do not use a replaceable component for longer than the recommended
replacement cycle. If you do, a deteriorating or worn-out component may cause
the equipment to fail.
・As you use a component, it gradually deteriorates and becomes subject to wear and tear. The
following components must be replaced at fixed intervals.
・Replacement of these components is not free of charge.
・The recommended replacement cycle in the following table assumes that the average ambient
temperature of the system unit is 25°C or less.
Note that when the average ambient temperature exceeds 25°C, the replacement cycle may be
shortened in some cases.

the HDD should be replaced every four years or when the
power-on hours count exceeds 20000 hours, whichever
comes first.
In order to ensure quick recovery of corrupted files,
routinely back up your files.
The expected life based on the limitation of Program /
Erase Count is able to calculate from the following
formula. The SSD should be replaced before the expected
life.

routinely back up your files.
If you do not replace a filter regularly, failure or shorter
life span of the equipment may result.
