Coupling the auxiliary fan power supply

  1. Plug in the plug connector for the auxiliary fan power supply.
  2. Route the supply cable with sufficient freedom of movement and without chafing points or pinching points.
  3. 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
