(a) With each new home, the manufacturer shall provide printed instructions which at a minimum must:      
        (1) specify the location, orientation and required capacity of stabilizing components on which the design is based;       
        (2) be filed with the Department;       
        (3) be approved by the manufacturer's DAPIA; and       
        (4) contain DAPIA approval stamps, engineer or architect approval stamps, and the installation manual effective date on each page of the installation instructions or on the cover pages of bound installation manuals, unless an equivalent method of authentication is used for electronically filed documents.       
      (b) For used manufactured homes, if a manufacturer determines that one or more of its homes requires a deviation from the generic standards to protect the structural integrity of the home, the manufacturer must include instructions for the necessary deviation in the manufacturer's DAPIA-approved installation instructions and provide a list of all homes affected. The manufacturer must provide a copy to the Department along with a letter informing the Department of the required deviation included in the instructions and giving the Department permission to reproduce and release copies of such instructions upon request. On the Department's website, the Department will maintain a current list of all required deviations from generic standards and will provide a copy to anyone who requests it.     
      (c) At least thirty (30) calendar days prior to the effective date of any change, modification, or update to the manufacturer's installation instructions or any appendix, the manufacturer shall file such change, modification, or update with the Department and mail a copy(s) to all the manufacturer's retailers. Links to appendix are posted on the Department's website.     
      (d) The manufacturer shall file with the Department additional copies of manufacturer's installation instructions for each model in the number specified by the Department. If no number is specified, one copy of each such set of instructions will suffice.
