63A859
ADD5C9
ADA162

Be aware that since JMeter 3.1 you should be using JSR223 Test Elements and Groovy language for scripting.

In Groovy it would be quite enough to call unique() function for the ArrayList and it will remove all the duplicates:

def array = ['ADD5C9', 
             'AA6F39',
             'AA3D0D',
             'AA48C9',
             '8B9D48',
             '63A859',
             'ADD5C9',
             'ADA162',
             'AD9AD5',
             '8B9D48']

def unique = array.unique()

unique.each { value -> log.info(value) }
