INSTALLATION STEPS

WATER FILTER HOUSING ON HOUSE MAIN WATER PIPE, TO FILTER ALL HOUSEHOLD WATER

A. USING COMPRESSION FITTINGS, FIG. 1

1.Apply several wraps of Teflon tape to the threads of both compression fittings.

2.CAREFULLY, turn the compression fittings into the water filter head inlet and outlet and tighten. Do not cross-thread and damage the threads. Do not over7 tighten and crack the head.

3.Remove the nut and brass ferrule from both com= pression fittings and set aside. Using a tape measure or ruler, measure the distance ``D'' as shown below. Mark this dimension below so you do not forget.

7.Place a nut and brass ferrule (from compression fit= tings) onto both pipe ends.

8.With the inlet side of the water filter facing in7 coming water, spread the pipes apart and fit both pipe ends into the compression fittings. Move a ferrule and nut up to the fitting. Then, turn on and tighten the nut. Hold the fitting with ￿ wrench while tightening the nut with the other. Repeat on the other side.

Note: If water flow is from right to left ( ➨), be sure to turn water filter so inlet is to the right.

Measure to shoulder inside of fittings. Copper pipe butts against this shoulder.

4.CAUTION: Turn off the water supply to the main pipe. Open a high and low faucet, in the water system, to drain the pipe.

5.On the main water pipe, where you will install the filter, mark the dimension D. You will remove this sec= tion of pipe. Before you begin to cut, double- check your measurement.

6.Use a tubing cutter to remove the section of pipe. Remove all burrs and rough edges with the sandpaper or emery-cloth.

9.Before turning on the water supply, remove the sump from the filter head and install the filter cartridge (see page 8).

IMPORTANT: The house cold water pipe is often used to ground electrical outlets in the home. Grounding protects you from electrical shock. The water filter housing may have broken this ground. To restore, buy and install a #￿ copper wire across the filter, tightly clamped at both ends as shown here.

B. SOLDERED COPPER FITTINGS, FIG. 2

MATERIALS AND TOOLS NEEDED: You will need ￿ sweat adaptors, 3/￿" 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.

CAUTION: Heat created when soldering can dam7

age the water filter housing. Be sure to use the fol= lowing procedures to protect the water filter.

1.CAUTION: 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 filter, use a tubing cutter to remove a section of pipe about ￿￿" long. Use sandpaper or emery-cloth to thor= oughly clean, and remove all burrs and rough edges, from both pipe ends.
