Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable local mechanical and plumbing codes, including the IPC and IFGC where applicable. Shut off and depressurize the piping system completely before removing or installing any threaded fittings. Apply appropriate thread sealant or PTFE tape to the male threads before engagement.
