Replace Fan for A-Frame Fan Housing
To replace an EC400 fan, you need to change the wiring so that the fan runs at
a different speed than what it does for the B-Frame drive.
1. Remove the three terminals in the front that are secured on the terminal
block in the fan housing, as shown.
2. Install the new wires of the resistor in reverse order of removal.
3. After you have changed the wiring, see Replace Fan for B-Frame Fan
Housing on page 32 for instructions on how to replace the fan.
To replace an EC500 fan, follow these instructions:
1. Remove the four M6 x 16 hexagon combination screws that secure the
noise reduction barrier, and remove the barrier.
