b) When fan filters are dirty
A front panel is provided with air filters for removing dust or dirt from the intake air.
When too much dirt accumulates in the filters, it can clog them and reduce air flow, causing higher
internal temperatures which can reduce reliability. Periodically check the condition of the air filters.
The air filters should be cleaned about once a month, or whenever fine dust has accumulated in the
filter.
To clear the air filters, rinse (with water, etc.) then dry them well. They should be completely dry when
reinstalled.
(1) Press the back of the left side of the air inlet
to the right and pull it.
(2) The left side will be unhooked. Hold the left
side and pull the inlet to the left forward to
release it from the unit.
(3) Take out the inside air filter from the back
side of the inlet and clean it.
(4) Perform steps (1) to (3) above to remove and
clean the other air filter.
(5) After the air filters are completely dry,
perform steps (1) to (3) in reverse order to
attach the air inlet covers.
Figure 8-1. Air Filter Cleaning Steps
The air filter will not function adequately if it becomes clogged, such as with very fine dust. To prevent
this, do not install this device in a location where there is a lot of dust (or fine dirt, etc.). Also avoid humid
locations where condensation occurs easily.
