Quick start/installation guide
Install after mechanical filtration on a pressure line; follow the flow arrow.
Solvent-weld 3/4" PVC into the sockets; allow full cure before pressurizing.
Use valves/unions to tune flow to your target dose and simplify service.
Keep power components dry/ventilated; do not submerge the unit.
Replace the lamp every 9–12 months of continuous use to maintain dose.
