7.8 Fans replacement
Fans should be checked 3 months after commissioning and thereafter depending on operating
conditions and as experience dictates, for any dirt build-up and/or unusual vibration, which could
ultimately cause damage to the fan or to the heat exchanger itself. Ensure complete electrical
isolation before removing fan guards. Fan blades should also be checked for any erosion or
corrosion and remedial action taken as necessary. All dirt and other contamination should be
removed to avoid imbalanced running of the fan and motor bearing overheating. The security of
the fan fastenings and the integrity of the components should be checked integrally as part of the
routine maintenance operation. Particular attention should be paid to the fastening screws and
balance of the fan blades.
Unscrew the fixing screws and remove the fan
grid.
Unscrew fixing bolts and remove old fan.
Remove elctrical connections.
