ASDA-B2
Life of Replacement Components
 Smooth capacitor
The characteristics of smooth capacitor would be deteriorated by ripple current
affection. The life of smooth capacitor varies according to ambient temperature and
operating conditions. The common guaranteed life of smooth capacitor is ten years
when it is properly used in normal air-conditioned environment.
 Relay
The contacts will wear and result in malfunction due to switching current. The life of
relay varies according to power supply capacity. Therefore, the common guaranteed
life of relay is cumulative 100,000 times of power on and power off.
 Cooling fan
The cooling fan life is limited and should be changed periodically. The cooling fan will
reach the end of its life in 2~3 years when it is in continuous operation. However, it
also must be replaced if the cooling fan is vibrating or there are unusual noises.
