Entry Boot Torque Specifications <br />Correct installation of entry boots is critical to a proper <br />installation. Excessive torque on the fastening nuts <br />may cause the bolts to pull away from the backer plate <br />hindering the boot's ability to seal to the sump wall. <br />When installing pipe into entry boots. piping must not be <br />more than 15 degrees from perpendicular to the sump <br />walls or the APT warranty will be voided. Entry angles <br />in excess of 15 degrees from perpendicular can cause <br />excessi ve stress, which may damage entry boots. <br />Flexible and ducted entry boots are designed to seal to the <br />flat walls of our sumps, but will work on rounded sumps <br />with a diameter of 36" (91.5 cm) or greater. <br />Note: Do not install pipe entries into the bottom of any APT <br />sump. <br />Follow the guidelines below. <br />Boot Fastening Nuts <br />HDPE without Permathane <br />60 <br />7 <br />Fiberglass without <br />75 <br />9 <br />Permathane <br />HDPE with Permathane <br />55 <br />6 <br />Fiberglass with <br />55 <br />6 <br />Permathane <br />Band Clamp <br />Flexible Side <br />25 <br />I <br />3 <br />Ducted Side <br />20 <br />2 <br />3 <br />
