Important Installation Instructions - 3M Filtrete 4WH-QS-S01 Installation And Operating Instructions Manual

IMPORTANT INSTALLATION INSTRUCTIONS

To reduce the risk associated with property damage due to water leakage:
• On plastic fittings, 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 fittings, as damage may occur if overtightening occurs.
Instructions below reference Figure 2.
1. Plan system location, support, layout and size.
2. Shut off main water supply. Depressurize water lines by opening a faucet downstream.
3. Using pipe cutters, remove a section of pipe in the install location corresponding to the size of the predetermined system assembly.
Keep a bucket and towel handy to catch and wipe up any water that drains from the line while cutting.
4. Assemble and install system as shown, observing correct flow direction of manifold. Use three shut-off valves and one filtration unit as shown.
Use copper pipe and sweated connections to assemble system. Support system by fastening bracket to wall or other framing. Alternatively, pipe
hangers may be installed on both sides of the filter head.
5. Insert filter into filter head. Push filter up, then turn one quarter of a turn to the right until it stops.
6. Ensure valve 1 and faucet downstream are open. Close valves 2 and 3. Turn on water supply, check for leaks.
7. While water is running through faucet, close valve 1, open valves 2 and 3. Allow filter to fill up.
8. Close valve 3, check for leaks again. If leaks, see Troubleshooting Section. If no leaks occur, open valve 3, let water run,
flushing air from the system for 10 gallons.
9. Close faucet.
10. Activate filter change indicator according to instructions on page 7.
