Emerson manual Time-Honored Features, Vilter 450XL Full Two-Year Warranty, Genuine Vilter Parts

Time-Honored Features

Vilter’s attention to detail shows wherever you look. Over a cen- tury of experience in refrigeration compressor design goes into each and every part that comprises the 450XL.

We have designed our component parts to work together, not just fit together. That’s why Vilter guarantees that all Genuine Vilter Parts will match your Vilter compressor dimensionally, metallurgi- cally and thermally for optimum compressor performance.

With Genuine Vilter Parts, you can be assured of getting the engi- neering design and special construction features that only Vilter can offer. Consider some of the special manufacturing steps that Vilter parts go through:

•Select surfaces are shot-peened for added strength

•Mating faces are lapped for greater compressor efficiency

•Many parts are ultrasonically inspected for maximum reliability

•The steels used are of special alloys for durable performance

•Exacting tolerances are measured in light bands rather than in hundredths of millimetres

The Vilter 450XL Full Two-Year Warranty

The 450XL compressor is fully warranted against defects of materi- als and workmanship under normal use and service, for a period of two years from date of shipment regardless of startup date.

For example, if startup occurs one month from shipping date, the customer will have a full twentythree (23) months of warranty coverage after startup.

Genuine Vilter Parts

When you need parts for your 450XL compressor – whether for repair work or scheduled maintenance – make sure you specify Genuine Vilter Parts.

Look for the Genuine Vilter Part mark that

is either etched or stamped directly on all major Vilter parts. It’s your assurance of Vilter warranty protection. In some cases, where a replacement part does not lend itself to stamping or etching,

a blue tag will identify the part as a Genuine Vilter Part. Vilter re- placement parts (except those too big to box) are shipped in boxes that have the Genuine Vilter Part mark right on the box itself.

Don’t be misled by look-alike, no-name imitations of Vilter com- pressor parts that carry vague warranties. Cheap parts can become an expensive mistake. Make sure you insist on using only Genuine Vilter Parts, and that you contact an Authorized Vilter Distributor (or Vilter direct) for all your 450XL parts requirements.
