Technical Service Bulletin
Created by: Lab.gruppen AB Service Department
Date: 080924
Reference no: FP+ Fans
Affected models
Following models are affected by this technical service bulletin:
FP 10000Q
FP 13000
Affected boards/modules
Fans.
Symptom
In some FP 10000Q and FP 13000 there is a possibility that wrong fans have been mounted.
The air flow of the wrong fans is not sufficient which affect the amplifier to not be able to
deliver full power when driven hard since they will get into thermal protection. Cooling is not
good enough if wrong fans are mounted.
Solution
Always check when servicing the FP 10000Q and FP 13000 amplifiers that correct fans are
mounted. If Nidec Beta fans are mounted those shall be exchanged to Sunon fans (F80x25-
24HSC).
