Installation - Type B

B. WATER FILTER ON HOUSE MAIN WATER PIPE, TO FILTER ALL HOUSEHOLD WATER

USING SOLDERED COPPER FITTINGS (See Figure 4 on Page 6)

MATERIALS AND TOOLS NEEDED:

You will need 2 sweat adaptors, 3/4" NPT x sweat (sweat end to fit your main water pipe), lead-free solder and flux, soldering torch, Teflon tape, sandpaper or emery cloth, open end (to fit sweat adaptor) or adjustable jaw wrench.

INSTALLATION STEPS

CAUTION: Heat created when soldering can damage the water filter’s plastic parts. Be sure to use the follow- ing procedure to protect the water filter.

1. IMPORTANT: Turn off the water supply to the main pipe. Open a high and low faucet in the water system to drain the pipe.

2. On the main water pipe, where you will install the fil- ter, use a tubing cutter to remove a section of pipe about 12" long. Use sandpaper or emery cloth to thor- oughly clean and remove all burrs and rough edges, from both pipe ends.

NOTE: When soldering, use lead-free solder and flux only. Be sure pipe and fittings are properly cleaned.

3. Solder a sweat adaptor onto one of the pipe ends (See Figure 11).

4. Place, but do not solder, a straight connector onto the other pipe end (See Figure 11).

5. Remove the sump from the filter head and set the sump aside.

6. After it cools, apply 4 wraps of Teflon tape to the threads on the sweat adaptor fitting (See Figure 12).

7. With the IN side of the water filter toward incoming water, carefully, turn the filter head onto the sweat adaptor fitting (See Figure 12). Do not cross-thread, or over-tighten and crack the filter head.

8. Turn a sweat adaptor fitting into the other side of the filter head and hand tighten only. Using a tape meas- ure or ruler, measure the distance “D” as shown in Figure 13. Mark this same dimension on a length of copper pipe. Cut the length of pipe.

9. Remove the sweat adaptor fitting from the filter head and solder to the cut length of pipe.

10. After it cools, apply 4 wraps of Teflon tape to the threads on the sweat adaptor fitting. Apply flux and

place the pipe end of the soldered assembly into the straight connector. Then, turn the adaptor end into the filter head and tighten.

11. Solder both sides of the straight connector.

12. Before replacing the sump and turning on the water supply, install the filter cartridge (See Page 11).

NOTE: Read the “Grounding Information” on Page 7, and comply with the instructions if required to maintain continuity.
