IMPORTANT INSTALLATION INSTRUCTIONS

To reduce the risk associated with property damage due to water leakage:
• On plastic fi ttings, never use pipe sealant or pipe dope. Use PTFE thread tape only, pipe dope properties may deteriorate plastic.
• Take care when using pliers or pipe wrenches to tighten plastic fi ttings, as damage may occur if overtightening occurs.
1. Shut off main water supply. Drain water from water lines and open faucet downstream of install location.
2. Remove filter cartridge from filter head and set aside.
3. Cut pipe to length needed to install filter head and recommended bypass.
4. Assemble filter head on optional bypass system as shown in Figure 1. Use three ball valves and one filtration
unit as shown. Use copper pipe and sweated connections to assemble system.
5. Install system (valves, piping and filter head) into water supply system.
6. Use supplied bracket or pipe hangers to support the system.
7. Install filter cartridge into head. Make sure internal key ring is positioned correctly by rotating to the right until it
snaps into place.
