6.2.1 Filter
The filter is a consumable. Its service interval is directly related to the seal and
cleanness status of the system room Check it monthly and replace it when it is dirty
in order to maintain efficient operation.
The filter is installed in front of the evaporator unit. Open the front door, and take it
out directly, as shown in Figure 6-1.

6.2.2 Blower
The blower package to be inspected includes: motor, impeller, blower package
fixation, and clearance between blower and impeller.
Inspect the motor bearing and impeller thoroughly every month and remove any
debris.
Check if the impeller is tightly mounted on the rotor of the motor and does not rub
against its neighboring metal components during rotation.
Since the blower package operates 24 hours every day continuously, any unusual
obstruction within the air circuit must be cleared in time to avoid damage of the
cooling system and other system components caused by reduced air volume.
