INSTALLATION
INSTALL DISCHARGE LINE TO PUMP HEAD AND INJECTION POINT
1. Make a secure finger tight connection on the discharge fitting of the pump head as
instructed in Install Suction Line instructions.
DO NOT use thread seal tape on pump tube connections or tools to
tighten connections.
HAZARDOUS PRESSURE: Shut off water or circulation system and
bleed off any system pressure.
Locate a point of injection beyond all pumps and filters or as determined by
the application.
2. A 1/4" or 1/2" Female NPT (FNPT) connection is required for installing the injection
fitting. If there is no FNPT fitting available, provide one by either tapping the pipe or
installing FNPT pipe tee fitting.
3. Wrap the Male NPT (MNPT) end of injection fitting with 2 or 3 turns of thread seal
tape. If necessary, trim the injection fitting quill as required to inject product directly
into flow of water.
