a Thermionic’s service engineer.
This warranty is expressly in lieu of all other obligations or liabilities on the part of Thermionics unless such
additional warranty is either agreed to in writing, appears in a separate warranty statement provided to the customer, or
appears in a warranty statement accompanying the product shipped to the customer. Under no circumstance will
Thermionics be liable for consequential or resulting loss or damage, whether of or due to causes covered by Thermionics’

customer. Written authorization for the return and instructions as to how these times should be shipped will be provided.
If any Thermionics products must be returned to the factory, they must be sent prepaid via the means of transportation

cases, Thermionics has sole responsibility for determining the cause of failure, and sole discretion in determining the
nature and extent of adjustment, if any, to which a customer may be entitled.
If it is found that our product has been returned without cause and is still serviceable, the customer will be
notified and the product be returned. All shipping costs on products returned for warranty repair shall be the customer’s
responsibility. Thermionic’s sole liability hereunder shall be the correction and/or replacement of defective materials and
