Return Procedures
To return the A643a TOC Analyzer for service, first obtain a returned material authorization
number (RA#). The RA# is necessary for any instrument that requires repair or calibration by
an authorized service center. Include the RA# on the shipping label when the instrument is
returned.
While the RA# process is described in this section, for the most up-to-date RA# process
information, including copies of all required forms, call Hach Ultra at 800.866.7889 or
+1 541.472.6500.
To return an instrument for credit, please contact the local sales representative.
WARNING
The following actions must be performed when returning any unit for any reason to prevent
personal injury and/or damage to the unit.
• Before shipping or storing the unit, run a test without attaching a sample vial to purge the
unit of all liquid.
• All analyzers returned for repair or replacement must be thoroughly cleaned with all
process material removed.
• Sludge contains bacteria that could be hazardous to Hach Ultra personnel. If a
contaminated unit is received, Hach Ultra reserves the right to have the unit removed
and destroyed by a hazardous material disposal team at the shipper’s expense.
