Fan Assembly
Notes:
1. Unless you have a particular reason to do so, do not switch off the using system or
the 2104 when removing or installing a fan assembly.
2. The diagrams in these instructions show a 2104 Model DU3. The procedure for a
2104 Model TU3 is the same, except that everything is turned through 90 degrees.
3. A fan assembly can be installed in either position at the back of the 2104. You can
easily distinguish it from the fan-and-power-supply assembly, because it has no DC
On/Standby switch or power connector.
Step 1. Refer to Figure 40.
Step 2. At the back of the 2104, unscrew the thumbscrews 1 of the fan assembly.
