Tubes being returned on a warranty claim are normally sent to authorized Varian distributor
or OEM from whom originally purchased. If returned directly to the Varian plant of
manufacture, the authorized Varian Distributor or OEM from whom purchased should be
notified in case there are some special instructions.
All products returned on a warranty claim must be shipped via prepaid freight and include a
completed copy of a service report form, a copy of which is included with every shipped
product. A warranty claim cannot be processed without this form. A copy of the original
invoice, bill of sale, or other purchase document should be included with the executed
service report form to establish purchase date and price.
The original Varian shipping carton and packing material should always be used for any
warranty claim return. Shipping damage because of poor packing will normally preclude
any warranty adjustment since the damage will usually make any testing or measuraments
impossible.
PARCEL POST SHOULD NEVER BE USED FOR SHIPMENT OF TUBES.
