To take measures below is suggested when units are used in the environment above.

1. Using units in the environment where units get watered or humidity is very high.
   (1)Semi-standard C(coating)
   (2)Stronger type than semi-standard C(Minor changed unit)
   
2. Using units in the environment where something conductive is dropped into a unit.
   (1)Install air filter to an exhaust part.
   (2)Semi-standard C(coating)
   (3)Stronger type than semi-standard C(Minor changed unit)
       1.Attaching tube and silicon rubber to high voltage part.
       2.Attaching isolation cover to high voltage part.
   
3. Using units in the environment where some gas get into units.
   (1)Some corresive gas cause units to be failed.Please contact us.
