6.2.2 Fan

The monthly inspection items of the fan kit includes: motor operation status, impeller status, fan kit fixation and
clearance between fan and impeller.
Inspect the motor bearing and impeller monthly and replace it if any damaged impeller is found.
Check that the impeller is tightly mounted on the rotor of the motor and does not rub against its neighboring metal
components during rotation.
Since the fan kit operates 24 hours every day continuously, any unusual airflow obstruction must be cleared in time to
avoid the damage to the cooling system and other system components caused by reduced air volume.
