1.1 Service and Warranty Guidelines
Some minor problems are readily corrected on site. If the product requires service, contact the MKS
Technical Support Department at +1-833-986-1686. If the product must be returned to the factory for
service, request a Return Material Authorization (RMA) from MKS. Do not return products without first
obtaining an RMA. In some cases, a hazardous materials disclosure form may be required. The MKS
Customer Service Representative will advise you if the hazardous materials document is required.
When returning products to MKS, be sure to package the products to prevent shipping damage.
Shipping damage on returned products due to inadequate packaging is the Buyer's responsibility.
