factory screen sieve analysis for three years from date of installation or for 30,000 pounds of coffee, whichever
comes first.
This warranty does not apply to any equipment, component or part that was not manufactured by Bunn or
that, in Bunn’s judgement, has been affected by misuse, neglect, alteration, improper installation or operation,
improper maintenance or repair, damage or casualty.
THE FOREGOING WARRANTY IS EXCLUSIVE AND IS IN LIEU OF ANY OTHER WARRANTY, WRITTEN OR
