WARNING!

There is a risk of the fans and panel falling down and causing an injury during the replacement operation.

Due to the weight of the fans (approx. 35 kg) and the panel (up to 25 kg), two technicians are required to carry out the fan

replacement.

BEFORE COMMENCING, ALWAYS CUT ALL THE ELECTRIC SUPPLY CIRCUITS ON THE MACHINE OFF.

Only properly trained and qualied personnel should work on this equipment.
