| 1. Attach a plywood backing board to the concrete to hold all the components required for the installation. Install a GFCI outlet to the board to supply power for the UV lamp system. | 2. Wrap the inlet valve with teflon tape (inset), then thread the solenoid valve onto the UV chamber. Don’t overtighten any of the threaded connections— tightening with your fingers is fine. | 3. Attach the UV chamber bracket clamp to the backer board with two screws. Slide the UV chamber into the bracket and tighten the band clamp just enough to support the unit. |

| 4. Make the wiring connections inside the power transformer box and attach it to the backer board with two screws. Position the transformer so it won’t obstruct the plumbing. | 5. Install a junction box to house the systems wiring. Connect the wiring harness for the solenoid valve first (inset) then run the transformer, power and solenoid leads to the junction box. | 6. Once the wiring connections are complete, start planning the plumbing. Attach the threaded connectors to the UV chamber and take the necessary measurments for the copper plumbing. |

| 7. Dry-fit all of the copper piping before soldering the connections. The inline valve shown above is necessary to isolate the system if and when servicing is required. | 8. Complete as much of the plumbing as possible before breaking into the main waterline. Install a 5-micron filter upstream from the UV filter to prevent debris from reaching the unit. | 9. To complete the installation, insert the UV lamp into the reaction chamber and connect the lamp wiring harness. Flush the whole system with chlorine bleach to disinfect the plumbing. |
