Open the inspection door by loosening the screws on the maintenance panel. Remove the electrical
connections from the motor block. The fan is secured on the panel by a set of four specific support
arms. To remove the fan, loosen the support arm securing screws using a spanner (open-ended, ring,
tube, etc.). Then loosen all four fan support arms. Replace the fan or carry out the maintenance
operation. Reposition the fan using the same support system, and connect using the connection
terminal block.
