Cleaning the Dust Filter
A dust filter is installed on the inside of the louver on the front panel.
Periodically clean the filter to prevent clogging.
CAUTION
•
Clogged dust filters hinder the cooling of the inside of the
instrument and can cause a malfunction and shortening of the
service life.
•
When the Booster is in operation, air is sucked through the dust
filter to cool the load booster. If moister is included in the dust
filter, the temperature or humidity inside the Booster increases
and may cause a malfunction.
