16 CFR § 700.9 - Duty to install under a full warranty.
Under section 104(a)(1) of the Act, 15 U.S.C. 2304(a)(1), the remedy under a full warranty must be provided to the consumer without charge. If the warranted product has utility only when installed, a full warranty must provide such installation without charge regardless of whether or not the consumer originally paid for installation by the warrantor or his agent. However, this does not preclude the warrantor from imposing on the consumer a duty to remove, return, or reinstall where such duty can be demonstrated by the warrantor to meet the standard of reasonableness under section 104(b)(1), 15 U.S.C. 2304(b)(1).
