Coupling the auxiliary fan power supply

- Plug in the plug connector for the auxiliary fan power supply.
- Route the supply cable with sufficient freedom of movement and without chafing points or pinching points.
- Switch on the 12 V electrical socket.
As soon as voltage is applied on the 12 V socket, the auxiliary fan starts rotating.
Every 20 minutes, the fan changes its direction of rotation for 40 seconds. The air current removes contamination from the cooler fins
