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 (F80 x25- 24HSC).
