Parts Included

filter housing SW-3A housing wrench

Tools Required

• 2 adjustable wrenches • file

• 2 pipe wrenches • pencil

• pipe threader • pipe cutter or hacksaw

Materials Required (not included)

Depends on type, size, and location of pipe on which filter will be installed.
Measure the pipe to determine what size nipples, union, and valve you will
need. If you are not installing on 1-inch pipe, you will also need to purchase
the appropriate size bushings. Consult your local hardware store to learn more
about your particular installation needs.

NOTE: Galvanized fittings must be used with galvanized pipe.

Optional Materials

• WBA mounting bracket

• jumper wire

NOTE:

• For cold water use only.

• Make certain that installation complies with all state and local laws and
regulations.

• The contaminants or other substances removed or reduced by the selected
cartridge are not necessarily in your water. Ask your local water municipality
for a copy of their water analysis, or have your water tested by a reputable
water testing lab.

• After prolonged periods of non-use (such as during a vacation) it is
recommended that the system be flushed thoroughly. Let water run for 5–6
minutes before using.

• The filter cartridge used with this system has a limited service life. Changes in
taste, odor, color, and/or flow of the water being filtered indicate that the
cartridge should be replaced.

• Some harmless bacteria may attack cellulose media cartridges.

The CP5-BBS

is not recommended on non-chlorinated water. If your cartridge seems to

disintegrate or develops a musty or moldy odor, switch to a synthetic media
cartridge or consult the manufacturer.

The HD-950A housing has been tested and certified by WQA against
NSF/ANSI Standard 42 for materials safety and structual integrity only.

Precautions

WARNING: Do not use with water that is microbiologically unsafe or of

unknown quality without adequate disinfection before or after the system.

CAUTION: Filter must be protected against freezing, which can cause cracking of

the filter and water leakage.

CAUTION: The rubber O-ring provides the water-tight seal between the cap and

the bottom of the housing. It is important that the O-ring be properly seated in the
groove above the threads of the housing or a water leak could occur.

CAUTION: Because of the product’s limited service life and to prevent costly

repairs or possible water damage, we strongly recommend that the bottom of all
plastic housings be replaced every ten years. If the bottom of your housing has
been in use for longer than this period, it should be replaced immediately. Date
the bottom of any new or replacement housing to indicate the next recommended
replacement date.

Installation

NOTE:

• Please read all instructions, specifications, and precautions before installing and using
your water filter.

• Install filter cartridge in housing before proceeding with installation (see Filter Cartridge
Replacement on page 3).

• Install filter after water meter or pressure tank.

• Numbered diagrams correspond with numbered steps.

1

1. Apply about 12 inches (300 mm) of Teflon® tape in clockwise direction to pipe threads
of each fitting.

2. If mounting bracket (not supplied) is to be used, attach to cap before assembling the fittings.

NOTE: Allow 1-1/2 inches (33 mm) clearance below housing to enable filter

cartridge changes.

3. Assemble all fittings. Start adapters into cap by hand.

Use a wrench to tighten firmly.

4. Measure length (shown as X on diagram) across assembled fittings and subtract 1 inch
(25 mm) if you are installing on 3/4 inch (19 mm) pipe, or 1-1/2 inches (38 mm) if
you are installing on 1 inch (25 mm) pipe. Mark section of pipe to be removed.

5. Using a pipe cutter or hacksaw, remove marked section of pipe and thread remaining
ends. Wrap threads with Teflon tape.

DO NOT OVER-TIGHTEN.

6. Align filter assembly with ends of pipe, making certain cap opening marked “IN” is facing
the incoming water supply. It will be necessary to spread ends of pipe apart to install filter
assembly. Using two adjustable wrenches, hold incoming adapter securely with one wrench
and tighten nut with second wrench. Repeat procedure for outgoing adapter.

CAUTION: If water pipes are used to ground electrical systems, appliances, or phones, be

certain to install a jumper wire. Contact your local electrician for more information.
