Check Your Water Pressure And Pumping Rate:

IMPORTANT NOTE

Two water system conditions must be checked carefully to avoid unsatisfactory operation or equipment damage:

1) Minimum water pressure required at the fi lter tank inlet is 20 psi (138 kPa).

CAUTION

To reduce the risk associated with property damage due to water leakage:

• Do not install if water pressure exceeds 100 psi. If your water pressure exceeds 80 psi (552 kPa), you must install a pressure limiting valve. Contact

a plumbing professional if you are uncertain how to check your water pressure.

IMPORTANT NOTE

If you have a municipal or a community water supply and daytime water pressure is 80 psi (552 kPa) or more, nighttime pressure may exceed
100 psi (689 kPa). Call your local water department or plant operator to obtain pressure readings. If you have a private well, the gauge on the
pressure tank will indicate high and low system pressure. Record your water pressure data below:

Water Pressure

Low _________psi High _________psi

2) The pumping rate of your well pump must be suffi cient for satisfactory BACKWASH. Although the density of a media normally determines the
backwash rate, all the media discussed earlier will require the same fl ow rate. Refer to SPECIFICATIONS AND OPERATING DATA for the backwash
requirement for models CBF100, CBF150 and CBF200. To measure the pumping rate of your pump, follow these instructions:

a. Make certain no water is being drawn. Open spigot nearest pressure tank. When pump starts, close spigot and measure time (in seconds) to

refi ll pressure tank (when pump shuts off). This fi gure represents CYCLE TIME.

b. With the pressure tank full, draw water into a container of known volume, measure the number of gallons drawn until the pump starts again.

This is DRAW-DOWN. Divide this fi gure by CYCLE TIME and multiply by 60 to arrive at the PUMPING RATE in gallons per minute (gpm). To aid in
you calculation, insert the data in the following formula:

DRAW-DOWN ______ ÷ CYCLE TIME ______ x 60 = PUMPING RATE ______
(gals.) (secs.) (gpm)

EXAMPLE: CYCLE TIME is 63 secs.; DRAWDOWN is 8 gals.; then PUMPING RATE equals:

8 gals. ÷ 63 secs. x 60 = 7.6 gpm

Locate Water Conditioning Equipment Correctly:

Select the location of your Backwash Filtration System with care. Various conditions which contribute to proper location are as follows:

1) Locate as close as possible to water supply source.

2) Locate as close as possible to a fl oor or laundry tub drain.

3) Locate in correct relationship to other water conditioning equipment.

4) Allow suffi cient space around the unit for easy servicing.

The Importance Of Your Pressure Tank:

A PROPERLY SIZED PRESSURE TANK WILL REQUIRE A MINIMUM PUMP CYCLE OF 60 SECONDS TO REFILL FROM PUMP ON-TO-OFF PRESSURE SET­TINGS.

NOTE: If your pressure tank (or any part of your water system) is not functioning properly, corrective action MUST be taken before installation of your
system.

IMPORTANT NOTES

IMPORTANT NOTES

C AUTION

• Damage due to heat is not covered under the manufacturer’s warranty and will void the warranty.

• The use of fl exible drain lines are prohibited in some states, check with your local code offi cer for requirements. Distance and height affects the perfor­mance of the drain line to discharge at the proper rate to effectively backwash the fi lter media. The following are guidelines for drain line size installa­tion. Do not bend the drain line too sharply if using fl exible tubing. Secure the drain line over the discharge line to prevent splashing or blow out during
regeneration. Do not use garden hose or vinyl tubing as a drain line as this may cause a failure to regenerate properly.

• You will need the serial number and model number of the unit to have certain parts replaced under warranty. Please preserve the shipping carton in case
the factory technical support services personnel request to verify your claim of missing or damaged parts.

• Activated carbon requires four (4) hours of saturation and Filter-Ag two (2) hours of saturation to prevent media from washing to the waste drain prior
to start-up.

Step 1

Inspect and open factory sealed box to ensure all components required for installation are present. If media was ordered, verify the amount and type of
fi lter media (ordered separately) is correct.

Step 2

Remove CBF Series Residential Backwash Filtration System from shipping carton and inspect to ensure there is no damage to product from shipping.
Inspect any packing for components that have been attached for shipping before discarding. If any items intended for installation are missing at this
time contact your Dealer/Installer or our Customer Service Department at 1-800-222-7880 to notify them of this situation and provide the model number
and serial number.

Step 3

For Threaded Tank Models: CBF100, CBF150, CBF200: Follow the steps to center the distributor tube and load the fi lter media into the media tank to
ensure the successful installation of your CBF Series Residential Backwash Filtration System.

a. Remove the control valve by rotating the valve head assembly to the left or counter-clockwise and set aside to reassemble after media is loaded into

the tank.

b. Tilt media tank to a 45 degree angle until gravel shifts to the side of the tank and dimple at bottom of media tank is visible. This will allow you to place the

distributor tube basket assembly in the dimple on the bottom of the media tank.

c. Place media tank back in upright position and ensure gravel at the bottom of the media tank is level. Place red plastic cap on the distributor tube that is

provided in the parts bag.

d. Locate the fi lter media that will be used in the backwashing fi lter and load into the media tank. Note: fi ll only to the labeled line on the outside of

the media tank. Refer to the Specifi cation section on page 5-1 for the correct quantity for your CBF Series Residential Backwash Filtration System.
Use a clean rag to wipe the opening of the media tank to remove any dust or sediment before moving to the next step.

Dome Hole Tank Models: CBF100DM, CBF150DM, CBF200DM:

a. Add media through fi llport cap located on tank using funnel (See FILLING MEDIA TANK below). Fillport cap can be removed by turning a quarter turn

counter clockwise.

CAUTION

To reduce the risk associated with skin, eye, and respiratory tract irritation from

dust from fi lter media during installation:

• Gravel and several types of fi lter media may be used in this product, depending upon the
application. During installation, dust may cause irritation to skin, eyes, and respiratory
tract, and may affect lungs.

• Utilize a NIOSH-approved dust fi lter mask and appropriate eye protection when handling
and pouring gravel and fi lter media.

• To request an MSDS relating to this product, call 203-238-8965 or go to www.3M.com ,
select country, and use the search engine to search MSDS. For emergencies, call 800-

364-3577 or 651-737-6501 (24 hours).

b. Reinstall fi llport cap by turning a quarter turn clockwise.

c. If bypass valve assembly is not factory pre-installed, attach using clips and screws.

d. Using a clean dry rag, wipe the opening of the media tank to remove any dust or residue from the opening to receive the control valve. Attach the

valve head to the media tank by rotating the valve head assembly to the right (clockwise).

2-2

FILLING MEDIA TANK

Step 4

CAUTION

Please refer to page 6-1 for Component Parts List.

Once the fi lter media has been loaded, completely fi ll the media tank with water using a pail or water hose to saturate the media and expel any air out of the
media tank. Some media require a saturation time to prevent washing it from the media tank to the waste drain upon start-up. Refer to Figure 4, page 2-4
for saturation time. Remove red cap from distributor tube.

Step 5

Secure the control valve onto the mineral tank. Insert the distributor tube into the pilot tube adapter and screw the control valve down until the valve is
fl ush with the opening of the mineral tank. If pinching or rolling of the o-ring occurs, remove the control valve and try again.

Step 6

Locate the installation assembly packet and assemble as the enclosed instructions dictate, refer to Figure 2. Attach the bypass assembly and connection
fi tting to the control valve and hand tighten only. Study the installation drawings provided (Figure 1) to determine the proper location of the Backwash
Filtration System in relation to the other components of the water system (i.e. water softener or water heater, if present) and install appropriately.

Step 7

Turn off the power to the well pump on a private well system or close the valve after the water
meter on a public or municipal water system. Depressurize and drain the water lines to allow for
connection of the plumbing to the bypass connection fi ttings on control valve. Be sure to attach the
supply line from the pressure tank or water meter to the INLET side of bypass valve and the service
line connected to the OUTLET side of bypass valve. Leave the bypass valve in the closed position
until instructed later in the installation process.

CAUTION

To reduce the risk associated with property damage due to water leakage:

• Do not apply heat to any fi tting connected to bypass or control valve as damage may result to
internal parts or connecting adapters.

Step 8

The drain line connection can utilize either a 3/4” NPT or a 5/8” COMPRESSION connection. To utilize
the 5/8” connection use the provided nut and insert sleeve with a 5/8” OD rigid or semi-rigid material.
Slide the nut over the tubing or piping fi rst, and then insert the sleeve into the piping or tubing until
fl ush. Finally insert piping or tubing in the drain elbow and thread the nut onto the elbow and hand
tighten only. To utilize the 3/4” NPT feature for a drain line connection, remove the 5/8” nut from the
elbow and provide your own connection device and piping for a drain line. Ensure the retaining clip is
securely in place before moving on. The discharge end of the drain line requires an air gap to prevent
a cross connection between grey water (sewage) and potable water (domestic). Refer to Figure 3 to
help in the installation.

a. 5/8” OD lengths up to 15 feet and heights lower or slightly higher than the control valve.

b. 3/4” OD length up to 25 feet in length and up to 4 feet above the control valve.

c. For distances higher or longer than previously stated, relocate the CBF Series Residential Back-

wash Filtration System closer to the desired discharge point or consult our Customer Service
Department at 1-866-990-9785 for advice. Avoid overhead drain lines as it may prevent desirable
performance.

Step 9

Connect the transformer to a suitable power supply that is non-switched to plug the transformer into that meets the local electrical code. The required
power source is 110 volt 60 Hz.

Step 10

Set the time clock for the correct time of day and set the frequency for regeneration appropriately. See “HOW TO SET TIME OF DAY” on page 2-5 for set­ting the time of day correctly.

2-3

Step 11

IMPORTANT NOTES

Determination of backwash frequency will vary by media used, the
amount of water used and the amount of contaminant in the water.
Most media should backwash once every four days in backwash fi ltra­tion systems containing activated carbon. If pressure drops become
undesirable or the contaminant reappears, increase the frequency to
correct. For media tanks containing calcite or magnesium oxide, the
frequency should be once every other day to help prevent cementing
of the media in the media tank. Correct backwashing frequency as
required. Tank should be marked for easier maintenance.

Step 12

If your CBF Series Residential Backwash Filtration System contains
activated carbon or fi lter sand proper saturation time is critical. Refer
to Figure 4 to determine the proper saturation time for that media type.

Activated Carbon 4 hours

Step 13

Turn on the electrical power to the well pump or open the valve on the municipal supply and pressurize the water line and check for leaks, correct as
required. Locate the regeneration button on the control valve and initiate a manual regeneration (see “HOW TO MANUALLY INITIATE IMMEDIATE REGEN­ERATION”), ensure the bypass valve is in the bypass position. Once the control valve stops in the fi rst position, unplug control valve so the valve will not
stage to another position to ensure proper start up and media classifi cation. Open the INLET side of bypass 1/4 turn to allow water to run slowly to the
waste drain until no air is heard in the drain line. Then slowly open the inlet side of bypass fully and let run until the waste water is clear, it should take
about 10 minutes. Then open the OUTLET side of the bypass into the fully open position. During the initial backwash cycle it is normal for a small amount
of “fi nes” to appear at the drain for proper preparation of media bed. It will subside within a few regeneration cycles and should not alarm you.

Step 14

Plug the control valve into the 110v 60Hz power source once again and ensure the time clock is properly set for time and frequency of regeneration. The
control valve will stage by itself and return to the service position.

IMPORTANT NOTES

Flush at least 10 gallons (37.9 liters) through this system during installation and maintenance. It may be necessary to continue fl ush­ing beyond 10 gallons until the water is clear.

Section 3: MAINTENANCE

1) At least every six months you should check the time of day setting. Power outages of two (2) hours or less will not affect the time clock as the
control valve has the ability to hold the correct time of day due to a battery on the printed circuit board. Power outages of more than two (2) hours
will require the resetting of clock to the correct time. Refer to Page 2-5 to resolve.

2) If your CBF Series Residential Backwash Filtration System contains activated carbon, replacement is required if the taste and odor being reduced
reappears in the treated water or if pressure drop due to fouling of the media becomes excessive.

3) Filter sand typically lasts an indefi nite period of time. It may be necessary to replace it, if the pressure drop across the fi lter bed becomes too great
or fi ltration results drops.

4) Calcite must be replenished at least annually. At the time of installation, it is advisable to mark the level of the media on the outside of the tank.
At a later date you can shine a bright light through the tank comparing the current level with the mark. If the level is down by more than three (3)
inches, add media back to the original mark.

TO REPLENISH (REBED) MEDIA:

CAUTION

To reduce the risk associated skin, eye, and respiratory tract irritation from gravel and fi lter media during installation:

• Gravel and several types of fi lter media may be used in this product, depending upon the application. During installation, dust may cause irritation to skin,
eyes, and respiratory tract.

• Utilize a NIOSH-approved dust fi lter mask, protective gloves, and appropriate eye protection when handling and pouring gravel and fi lter media.

• To request an MSDS relating to this product, call 203-238-8965 or go to www.3M.com, select country, and use the search engine to search MSDS. For
emergencies, call 800-364-3577 or 651-737-6501 (24 hours).

1) Pressure must be relieved on water treatment system by turning the bypass valve to the bypass position. Then initiate an immediate manual regen­eration cycle as described on Page 2-5.

2) Disconnect the power cord from the electrical outlet.

3) Remove the drain line for the control valve. Remove the control valve by rotating the valve head assembly to the left or counter-clockwise and set aside
to reassemble after media is loaded into the tank.

4) For Threaded Tank Models: CBF100, CBF150, CBF200: Using fl exible tubing, insert down the distributor tube and siphon the water from the media tank to
aid in adding or replacing fi lter media. Cover the distributor tube with the extension tube and cap to prevent media from entering the distributor tube.

a. If using calcite or neutralizer media, add the media you are using to the line on the side of the media tank. Then refi ll the media tank with water

utilizing a hose or clean bucket. Proceed to Step # 5.

b. If utilizing activated carbon media that needs to be entirely replaced you will need to empty the media tank of both the gravel underbed and media. The

use of a garden hose and several buckets to place the spent media into is helpful. The changing of the media should take place outdoors as this can
be messy. Once the media tank is emptied, you can rinse the media tank out and inspect the distributor for damage or fi nes being lodged into the slots
of the basket assembly. Clean as required before loading the media with gravel or fi lter media. Place the distributor into the media tank and ensure it
is in the dimple on the bottom of the media tank. Utilizing the extension tube, red cap and funnel place over the distributor tube and into the opening
of the fl anged tank. Next take the correct amount of gravel and dump into the media tank. Hold the distributor tube and gently shake the media tank
to level the gravel in the media tank. Next load the fi lter media into the media tank to the proper level. This can be determined by observing the media
level line on the outside of the media tank. Gently shake the media tank to level the media. Using a hose or clean bucket fi ll the media tank with water
to help saturate the fi lter media before placing the control valve on the media tank. Using a clean rag or paper towel, wipe the opening of the media
tank to remove any media fi nes before attaching the control valve. Dispose of spent media in accordance with federal, state, and local regulations.

Dome Hole Tank Models: CBF100DM, CBF150DM, CBF200DM:

a. Add media through fi llport cap located on tank using funnel (See FILLING MEDIA TANK below). Fillport

cap can be removed by turning a quarter turn counter clockwise.

b. Reinstall fi llport cap by turning a quarter turn clockwise.

c. If bypass valve assembly is not factory pre-installed, attach using clips and screws.

d. Using a clean dry rag, wipe the opening of the media tank to remove any dust or residue from the

opening to receive the control valve. Attach the valve head to the media tank by rotating the valve head
assembly to the right (clockwise).

5) Reattach valve head assembly by rotating to the right or clockwise until valve head assembly is seated to the tank
hand tight.

6) Reattach the bypass valve to the control valve and slowly open the bypass. Allow the Backwash Filtration System to fi ll with water and set for the
required time period. Refer to Figure 4, page 2-4 to determine the amount of time to wait before backwashing can occur.

7) Plug the control valve into the electrical outlet and set the time of day on the display.

8) Once the saturation time has been achieved, manually initiate an immediate regeneration (see Page 2-5). Backwash the media until the water runs
clear. Observe the color of the water in the drain line discharge to determine if is has washed long enough. The water should be fairly clear and absent
of fi nes before quitting the cleaning process. If not, proceed to regenerate the unit again until the water runs clear to the waste drain.

9) Re-bedding of media tank is now complete.
