Sears 625.3438 operating instructions Installation Steps

INSTALLATION STEPS

6.Using females and compression nuts, cut and fasten a length of tubing (allow some slack) from the cold water' pipe, to the filter head inlet compression adap- tor', FIG5.

7.Cutting to the length needed to allow some slack, fasten tubing to the filter outlet side compression adaptor; returning to the sink cold water pipe, as typi- cally shown in FIG. 6

8.Check to be sure all fittings are tightened.

9.Before turning on the water supply, remove the sump from the filter' head and install the filter cartridge (see page 7).

B. SOLDERED COPPER FrITINGS, FIG. 2

MATERIALS AND TOOLS NEEDED: You will need 2

sweat adaptors, 3/8" NPI' x sweat (sweat end to fit your' sink cold water pipe), 4 sweat 90°elbows,

copper' pipe, lead-flee solder and flux, soldering

torch, Teflon tape, sandpaper or emery-cloth, open end (to fit sweat adaptor) or adjustable jaw wrench.

CAU_£ION: Heat	created when	soldering	can	dam.
age the water	filter housing.	Be sure	to use	the fol-
lowing procedures to protect the water' filter'

Note: If the sink faucet is a single lever, mixing type,

also close the shutoffvalve on the hot water side.

2.Use a tubing cutter' to remove a section of the sink cold water pipe (catch trapped water with a rag or towel).. Use sandpaper' or emery-cloth to thoroughly clean, and remove all bur,s and rough edges, from both pipe ends

Note: When soldering, use lead-freesolder and flux

only. Be sure pipe and fittings are properly cleaned Observe caution note above,

3.Refer' to FIG, 2, page 5, and to the following draw- ings, Make typical soldered assemblies A and B as shown in FIG, 7 After they have cooled, apply Tef!on tape or pipe joint compound to the pipe threads, Then, turn them into the filter' head and tighten

4.Solder' the filter' housing, with assemblies A and B installed, to the cold water shutoff valve C. Wrap a wet

rag around assembly A to reduce heat trans[er through the pipe, and into the head.

5.Protect the filter housing fiorn soldering heat, as you did above, and complete the cormections (D) to the faucet cold water pipe

6.Before turning on the water supply, remove the sump from the filter head and install dae filter cartridge (:;ce page 7)
