2-1-2. Replacing the DC Fan (HDCU1000/1080)
c
If the fan is defective, the temperature inside HDCU1000/
1080 will rise. Touching the inside of the unit in this state
may cause a burn.
Replace the parts after turning off the power and cooling
the inside.
The fans that are used in the rear panel of HDCU1000/
1080 are recommended replacement parts.
The lifespan of these fans is about 30,000 hours, which
means that the fans can be used for about three and a half
years if the power is on all the time, so as a guideline the
fans should be replaced every three and a half years.
1. Turn off the main power and disconnect the plug from
the outlet.
2. Remove the switching regulator.
(Refer to Section 2-1-1.)
