Taste & Odor Filter (Activated Carbon)
Unpleasant tastes and doors caused by chlo-
rine or organic substances, such as decayed
vegetation and run off, are absorbed by top
quality activated carbon. The filter will auto-
matically backwash to a predetermined
schedule. This frees the bed of accumulated
impurities and readies it for operation again.
Multi-Media Filter (Sediment)
Suspended particulate matter such as clay
and silt, which gives water a cloudy appear-
ance, is trapped in the filter bed to produce
clean, clear water. A variety of gravel and
sand facilitates more thorough backwashing
and prevents channeling. eriodic backwash-
ing cleans the bed.
Neutralizing Filter
The neutralizing filter contains blended media
which raises the pH of acidic water and neu-
tralizes its corrosive characteristics. In addi-
tion to protecting pipes, plumbing fixtures
and appliances, this filter also facilitates the
removal of iron and manganese by raising
the pH. This enables an iron filter to be used.
eriodic backwashing cleans the bed. Addi-
tional media may be required six months to
two years after installation, depending on the
water’s pH.
Before Starting Installation
Tools, ipe, and Fittings, Other Materials
 liers
 Screwdriver
 Teflon tape
 Razor knife
 Two adjustable wrenches
 Additional tools may be required if modifi-
cation to home plumbing is required.
 lastic inlet and outlet fittings are included
with the filter. To maintain full valve flow,
3/4” or 1” pipes to and from the filter fit-
tings are recommended. You should main-
tain the same, or larger, pipe size as the
water supply pipe, up to the softener inlet
and outlet.
 Use copper, brass, or EX pipe and fittings.
 Some codes may also allow VC plastic
pipe.
 ALWAYS install the included bypass valve,
or 3 shut-off valves. Bypass valves let you
turn off water to the filter for repairs if
needed, but still have water in the house
pipes.
 5/8” OD drain line is needed for the valve
drain. A 10’ length of hose is included.
with some models.

 Place the filter tank as close as possible to
the pressure tank (well system) or water
meter (city water).
 Place the filter tank as close as possible to
a floor drain, or other acceptable drain
point (laundry tub, sump, standpipe, etc.).
 Connect the filter to the main water supply
pipe BEFO E the water heater. DO NOT
RUN HOT WATER THROUGH THE FIL-
TER. Temperature of water passing
through the filter must be less than 100
deg. F.
 Do not install the filter in a place where it
could freeze. Damage caused by freez-
ing is n t c vered by the warranty.
 Put the filter in a place water damage is
least likely to occur if a leak develops. The
manufacturer will not repair or pay for wa-
ter damage.
 A 120 volt electric outlet, to plug the in-
cluded transformer into, is needed within 6
feet of the filter. The transformer has an
attached 6 foot power cable. Be sure the
electric utlet and transf rmer are in
an inside l cati n, t pr tect fr m
wet weather.
 If installing in an outside location, you
must take the steps necessary to assure
the filter, installation plumbing, wiring,
etc., are as well protected from the ele-
ments, contamination, vandalism, etc., as
when installed indoors.
 Keep the filter ut f direct sunlight.
The sun’s heat may soften and distort
plastic parts.
Where T Install The Filter

Sizing Requirements
Water Pressure
The water system must have a pump big enough to deliver the recommended backwash
rate with a minimum pressure at the inlet of the filter of 30 psi. If the existing system can-
not do this, it must be upgraded to do so. henever possible, the water system should be
adjusted to deliver at least 30 psi for even more satisfactory results.
Backwash Flow Rates
The most important criteria in sizing a filter is the capacity of the pump. The water must
pass through the filter media at the proper service flow rate. The filter must also be back-
washed at a flow rate sufficient to dislodge and remove the captured particles. Failure to
provide sufficient water will cause a build-up of particles in the filter media, impairing its
ability. In order for your filter to backwash and rinse properly, your pump must be capable
of providing the backwash flow rates indicated on page 4.
Check Your Pumping Rate
Two water system conditions must be checked carefully to avoid unsatisfactory operation or
equipment damage:
1. Minimum water pressure required at the filter tank inlet is 20 psi.
2. Measuring the pumping rate of your pump:
ith the pressure tank full, draw water into a container of known volume, and measure the
number of gallons drawn until the pump starts again. This is draw-down. Divide this figure
by cycle time and multiply the result by 60 to arrive at the pumping rate in gallons per min-
ute (gpm). To aid in your calculation, insert the date in the following formula:
DRA -DO N ______ ÷ CYCLE TIME _______ x 60 = PUMPING RATE ________ (gals)
(secs.) (Gpm)
EXAMPLE: CYCLE TIME is 53 seconds. DRA -DO N is 6 gallons; then, PUMPING
RATE equals:
6 gallons ÷ 53 seconds x 60 = 6.8 gpm
See chart on page 4 for minimum flow rates.
NOTE: If your pumping rate is inadequate for the model, do not install your filter until
the problem has been corrected.

1. If your hot water tank is electric, turn off the power to it to avoid damage to the element
in the tank.
2. If you have a private well, turn the power off to the pump and then shut off the main wa-
ter shut off valve. If you have municipal water, simply shut off the main valve. Go to the
faucet, (preferably on the lowest floor of the house turn on the cold water until all pres-
sure is relieved and the flow of water stops.
3. Locate the filter tank close to a drain where the system will be installed. The surface
should be clean and level.
4. Connect the inlet and outlet of the filter using appropriate fittings. Perform all plumbing
according to local plumbing codes.
 Use a ½” minimum pipe or tubing size for the drain line
 ON COPPER PLUMBING SYSTEMS BE SURE TO INSTALL A GROUNDING
WIRE BETWEEN THE INLET AND OUTLET PIPING TO MAINTAIN GROUND-
ING.
Any solder joints near the valve must be done before connecting any piping to the valve.
Always leave at least 6" (152 mm between the valve and joints when soldering pipes that
are connected to the valve. Failure to do this could cause damage to the valve.
5. Connect the drain hose (10 ft included to the valve and secure it with a hose clamp (also
included . Run the drain hose to the nearest laundry tub or drain pipe. This can be ran
up overhead or down along the floor. If running the drain line more than 20 ft overhead,
it is recommended to increase the hose size to 3/4”. NEVER MAKE A DIRECT CONNEC-
TION INTO A WASTE DRAIN. A PHYSICAL AIR GAP OF AT LEAST 1.5” SHOULD BE USED
TO AVOID BACTERIA AND WASTEWATER TRAVELLING BACK THROUGH THE DRAIN
LINE INTO THE FILTER.
6. Using the Allen Key (included , place the unit in the bypass position. Slowly turn on the
main water supply. At the nearest cold treated water tap nearby remove the faucet
screen, open the faucet and let water run a few minutes or until the system is free of any
air or foreign material resulting from the plumbing work.
7. Make sure there are no leaks in the plumbing system before proceeding. Close the water
tap when water runs clean.
8. Proceed to start up instructions.
Note: The unit is not eady fo se vice until you complete the sta t-up inst uc-
tions.
