The warranty is limited to parts-only replacement and
shipping of any faulty part or sub-assembly which has

unit has been operated within the design parameters.
All warranty claims must specify the unit model, serial

trained personnel from an Authorized YORK Ser-
vice Center. See Commissioning, page 42.
