(3) Cleaning and Replacement of Filter

IS-120B has filters at its intake and outlet (See the figure below).
Clean the filters once a half year observing the following procedures.
If it gets badly stained, replace it with a new one.    If the filter is clogged, air does not
flow enough, causing internal temperature to rise and malfunction.

•

Miyachi Technos Corp. does not have a replacement filter; please purchase it
from manufacturer.
