6.2.2. Fan
The monthly inspection particulars of the fan kit include: fan status, fan kit fixation, and clearance between fan
impeller and inlet nozzle. Inspect the motor bearings and impeller monthly; and replace it if any damaged found
in impeller. Check the impeller is tightly mounted on the rotor of the motor and does not obstruct against its
neighboring metal components during rotation.
Since the fan kit operates 24hours every day continuously, any unusual airflow obstruction must be cleared in
time to avoid the damage to the cooling system. This unusual airflow obstruction can also aect to the other
system components due to reduction in air volume. Refer Figure 6-2 for better understanding.
