The documentation details the physical dimensions and construction requirements for adapting the legacy unit model 585/579E-J 048-060 to the new unit model PCG/PHG/PCE/PHE A24-42. It emphasizes G90 galvanized steel construction, fully insulated supply and return plenums, and provides critical verification steps for site installers regarding existing curb dimensions and duct configurations. The document specifies that units up to 12.5 tons should operate under 0.35 inches of total static pressure, while 15-25 ton units are restricted to 0.625 inches. With a precise weight of 156.834 pounds, this engineering sheet serves as a guide for correct installation, unit identification, and safety compliance in retrofitting applications.",{"@graph":69,"@context":122},[70,84,105],{"@type":71,"itemListElement":72},"BreadcrumbList",[73,77,79,82],{"item":74,"name":75,"@type":76,"position":8},"https://docshare.wps.com","Home","ListItem",{"item":78,"name":9,"@type":76,"position":14},"https://docshare.wps.com/document/",{"item":80,"name":30,"@type":76,"position":81},"https://docshare.wps.com/document/technology/",3,{"item":83,"name":65,"@type":76,"position":19},"https://docshare.wps.com/document/curb-adaptor-york-international-80-290-4965-technical-specification/663852/",{"url":83,"name":65,"@type":85,"image":86,"author":91,"headline":65,"publisher":94,"fileFormat":97,"inLanguage":63,"description":67,"dateModified":98,"datePublished":99,"encodingFormat":97,"isAccessibleForFree":100,"interactionStatistic":101},"DigitalDocument",{"url":87,"@type":88,"width":89,"height":90},"https://docshare.wps.com/thumbnails/curb-adaptor-york-international-80-290-4965-technical-specification/663852.png","ImageObject",300,407,{"name":92,"@type":93},"Noah","Person",{"url":74,"name":95,"@type":96},"DocShare","Organization","application/pdf","2026-10-30","2026-10-29",true,{"@type":102,"interactionType":103,"userInteractionCount":14},"InteractionCounter",{"@type":104},"ViewAction",{"@type":106,"mainEntity":107},"FAQPage",[108,114,118],{"name":109,"@type":110,"acceptedAnswer":111},"What materials are used for the construction of this curb adapter?","Question",{"text":112,"@type":113},"The curb adapter is constructed using fully welded G90 galvanized steel, with supply and return plenums that are fully insulated.","Answer",{"name":115,"@type":110,"acceptedAnswer":116},"What are the operating pressure requirements for the curb adapters?",{"text":117,"@type":113},"Adapters for units up to 12.5 tons are designed for less than 0.35 inches of total static pressure, while those for 15-25 ton units must be less than 0.625 inches.",{"name":119,"@type":110,"acceptedAnswer":120},"What verification steps must be taken before installation?",{"text":121,"@type":113},"Installers must verify existing curb dimensions, check supply and return ducts, document any variations, and contact RRS for concerns or drawing verification.","https://schema.org",{"og:url":83,"og:type":124,"og:title":65,"og:site_name":95,"og:description":67},"article",{"robots":126,"canonical":83},"index,follow",{"doc_id":128,"site_id":62},663852,1793232857,{"code":4,"msg":5,"data":131},{"doc_id":128,"user_id":132,"nickname":92,"user_avatar":133,"doc_module":4,"category_id":29,"category_name":30,"doc_title":65,"doc_description":67,"doc_content":134,"file_id":135,"file_url":136,"file_type":137,"file_size":138,"view_count":14,"is_deleted":4,"is_public":8,"is_downloadable":8,"audit_status":8,"page_count":8,"language":139,"language_code":63,"site_id":62,"html_lang":63,"table_of_contents":140,"faqs":141,"seo_title":142,"seo_description":67,"update_tm":129,"read_time":81},8796095462418,"https://ap-avatar.wpscdn.com/avatar/80000253c1241d02b47?x-image-process=image/resize,m_fixed,w_180,h_180&k=1778826106357471780","| |  |  | APRV'D BY:  DATE:  |  |  |  |  |  |\n| --- | --- | --- | --- | --- | --- | --- | --- | --- |\n|  |  |  | 8.125 |  | \u003Cbr>18.000 |  |  |  |\n| | \u003Cbr>\u003Cbr>17.000 \u003Cbr>EXISTING CURB\u003Cbr>\u003Cbr>\u003Cbr>17.000 17.000\u003Cbr>\u003Cbr>17.000\u003Cbr>~~   ~~ 4.000\u003Cbr>\u003Cbr>|  | 19.875 | |  |  |  | 19.875 |\n|  |  |  |  71.500 \u003Cbr>SIDE VIEW |  |  |  |  |  |\n|  | |  |  |  |  |  |  |  |\n| \u003Cbr>1625 DIPLOMAT DR. , CARROLLTON, TX 75006-6848 Phone: (972) 247-7447 (800) 552-4822\u003Cbr>Fax: (972) 243-0940 |  | NOTES:\u003Cbr>1.
