Maintenance
Smudges and dirt on the unit's window can interfere with the unit's performance.
If the window requires cleaning, use only a mild glass cleaner containing no
ammonia. When cleaning the window, spray the cleaner onto a lint free, non-
abrasive cleaning cloth then gently wipe the window clean.
If the unit's case requires cleaning, use a mild cleaning agent that does not
contain strong oxidizing chemicals. Strong cleaning agents may discolor or
damage the unit's exterior.
