Due to ongoing product improvements, specifications and dimensions are subject
to change and correction without notice or incurring obligations. Determining
the application and suitability for use of any product is the responsibility
of the installer. Additionally, the installer is responsible for verifying
dimensional data on
the actual product prior to beginning any installation preparations. Third
party incentive and rebate programs have precise requirements as to product
performance and certification. All products meet applicable regulations in
effect on date of manufacture; however, certifications are not necessarily
granted for the life of a product. Therefore, it is the responsibility of the
applicant to determine whether a specific model qualifies for these
incentive/rebate programs.

but not limited to, the Safe Drinking Water and Toxic Enforcement Act of 1986,
