Replacement Of Expendable Parts; Warranty - Toshiba TOSVERT VF-AS1 Instruction Manual

6. Replacement of expendable parts

The PB unit is composed of a large number of electronic parts including
semiconductor devices. The following parts deteriorate with the passage of time
because of their composition or physical properties. The use of aged or deteriorated
parts leads to degradation in the performance or a breakdown of the equipment. To
avoid such trouble, the PB unit should be checked periodically.
note) Generally, the life of a part depends on the ambient temperature and the
conditions of use. The life spans listed below are applicable to parts when used
under normal environmental conditions.
1) Cooling fan
The fan, which cools down heat-generating parts, has a service life of about 10
years (average ambient temperature : 40℃, operation time : 12 hours per day).
The fan also needs to be replaced if it makes a noise or vibrates abnormally.
2) Smoothing capacitor (for PB7-4400K, 6300K, 6400K)
The smoothing aluminum electrolytic capacitor in the main circuit DC section
degrades in performance because of ripple current, etc. It becomes necessary to
replace the capacitor after it is used for about 5 years under normal conditions
(average ambient temperature : 40℃, load factor : not more than 80%, operation
time : 12 hours per day).
note) When it becomes necessary to replace expendable parts, contact your
supplier. For safety's sake, never replace any part on your own.
