Notes:
14" on center offset shown is recommended minimum with
installation of STP/IST #1 prior to that of STP/IST #2. A smaller
offset or other changes to the STP/IST installation may require a
larger sump riser diameter, alterations or additions to the piping
shown, turning of the STP/IST's other than shown to accommodate piping,
or disassembly of the junction box from the STP/IST to allow for turning
of assembly into the tank. Minimum offset of STP/IST's is 12".
*STP/IST must be used with either the STP-SC or IST-VFC (IST 2 HP only) controllers for proper mechanical line leak detection, see TB013 for details.
