REPLACING THE FAN
Open the fan access door (side doors) by releasing the closing latches using an Allen key (for hexagon socket bolts).
Remove the connection block located behind the motor by undoing the mounting bolts. The fan is attached to the
panel by an assembly of four specific support arms. To remove the fan from the recovery unit, undo the mounting
bolts on the support arms using a spanner (flat, ring, pipe, etc.). Then release the assembly of four fan support arms.
Replace the fan or perform the maintenance operation. Refit the fan using the same support system and connect it
using the connection block.
