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.
