7.8 Fans
Fans should be checked 3 months after commissioning and thereafter depending on operating con-
ditions and as experience dictates, for any dirt build-up and/or unusual vibration, which could ulti-
mately 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.
