10.5 - EC fan replacement
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 qualified personnel should work on this equipment.
How to remove the fans
Remove the front panel (or a grid) to get access to the fan bays (see pictures below).
Note:
• Downflow Down - remove floor panels positioned in front of the unit to get access to the fan section frontal grid. Remove any
obstacles in front of the fans to allow the fan extraction (e.g. the raised floor structure, piping)
