Installation Notes
- Shut off the pump and relieve system pressure before servicing any feeder plumbing.
- Confirm the injection point is on the return line after the filter and heater (per feeder installation guidelines).
- Cut tubing cleanly and square; ensure tubing is fully seated before tightening nuts/clamps.
- Do not over-tighten plastic threads or fittings—snug plus a small additional turn is typically sufficient.
- After reassembly, restart the system and check carefully for leaks during operation.

Maintenance Tips
- Inspect feeder tubing and fittings seasonally—replace any brittle, discolored, or cracked tubing to reduce leaks.
- Keep water chemistry balanced; scaling and corrosion accelerate wear on small feeder fittings and valves.
- After any plumbing service, monitor the first few run cycles for slow seepage around saddle clamps and tubing nuts.
- Use only silicone lubricant on seals/O-rings (never petroleum-based lubricants).
