INSTALLATION STEPS

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

overtighten 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.

8.With the inlet side of the water filter facing in- coming water, spread the pipes apart and fit both

pipe ends into the compression fittings. Move a fer- rule and nut up to the fitting. Then turn on and tight- en the nut. Hold the fitting with one wrench while tight- ening the nut with the other. Repeat on the other side.

Note: If water flow is from right to left ( O O J ), 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

section of pipe. Before you begin to cut, double- check your measurement.

9. Before turning on the water supply remove the sump from the filter head and install the filter car- tridge (see page 9).

IMPORTANT: The house cold water pipe is often used to ground electrical outlets in the home. Ground- ing protects you from electrical shock. The water fil- ter housing may have broken this ground. To restore, buy and install a #4 copper wire across the filter, tight- ly clamping at both ends as shown here.

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

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

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.

CAUTION:		Heat	created		when soldering				can dam-
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.
