GENERAL OPERATING DISPLAYS & NAVIGATION

During normal operation, the default user displays are “time of day” and “gallons per minute”. Flow rate, vacation mode, capacity remaining, and

days to a regeneration are optional displays. For more explanation, consult the “operating displays and maintenance section”. Pressing the NEXT

button on a general operating screen will cycle through the available operating displays.

In any screen other than a general operating display, the NEXT button will proceed to the next step, the REGEN button will return to a previous step,

and the CLOCK button will return to the general operating displays. Any changes made prior to the exit will be incorporated. If no buttons are pressed

within five minutes, the display will return to the general operating displays.

ULTRA FILTRATION FLUSHING SCHEDULE

The UF Series Filter is factory preset to backwash every day at midnight. This is dependent on the quality of water being treated and may

be adjusted by the installing dealer based on the water quality. A post ultra-filtration pressure tank may be installed to ensure a sufficient

flow of water and pressure to the home during a flush cycle.

IMPORTANT: If a post pressure tank is used a check valve may be required to allow for treated water regeneration. In this case an

expansion tank should be installed to account for thermal expansion. See drawing in the back of this manual.

BYPASS VALVE

The bypass valve is typically used to isolate the control valve from the plumbing system’s water pressure in order to perform control

valve repairs or maintenance. The 1” full flow bypass valve incorporates four positions, including a diagnostic position that allows a

service technician to have pressure to test a system while providing untreated bypass water to the building. Be sure to install bypass

valve onto main control valve before beginning plumbing or make provisions in the plumbing system for a bypass. The bypass body and

rotors are glass-filled Noryl® and the nuts and caps are glass-filled polypropylene. All seals are self-lubricating EPDM to help prevent

valve seizing after long periods of non-use. Internal “O” Rings can easily be replaced if service is required.

The bypass consists of two interchangeable plug valves that are operated independently by red arrow shaped handles. The handles

identify the direction of flow. The plug valves enable the bypass valve to operate in four positions.

1. NORMAL OPERATION POSITION: The inlet and outlet handles point in the direction of flow indicated by the engraved

arrows on the control valve. Water flows through the control valve for normal operation of a water softener or filter. During the

regeneration cycle this position provides regeneration water to the unit, while also providing untreated water to the distribution

system (Fig. 1).

2. BYPASS POSITION: The inlet and outlet handles point to the center of the bypass. The system is isolated from the water

pressure in the plumbing system. Untreated water is supplied to the building (Fig. 2).

3. DIAGNOSTIC POSITION: The inlet handle points toward the control valve and the outlet handle points to the center of bypass

valve. Untreated supply water is allowed to flow to the system and to the building, while not allowing water to exit from the system

to the building (Fig. 3). This allows the service technician to test the unit and perform other functions without disrupting the water

going to the building.

NOTE: The system must be rinsed before returning the bypass valve to the normal position.

4. SHUT OFF POSITION: The inlet handle points to the center of the bypass valve and the outlet handle points away from the

control valve. The water is shut off to the building. The water treatment system will depressurize upon opening a tap in the building.

A negative pressure in the building combined with the unit being in regeneration could cause a siphoning to the building. If water

is available on the outlet side of the unit, it is an indication of water bypassing the system (Fig. 4) (i.e. a plumbing cross-connection

somewhere in the building).

Bypass Valve

INSTALLATION

GENERAL INSTALLATION & SERVICE WARNINGS

The control valve, fittings and/or bypass are designed to accommodate minor plumbing misalignments. There is a small amount of “give”

to properly connect the piping, but the water filter is not designed to support the weight of the plumbing.

Do not use Vaseline

, oils, other hydrocarbon lubricants or spray silicone anywhere. A silicone lubricant may be used on black “O” Rings,

but is not necessary. Avoid any type of lubricants, including silicone, on red or clear lip seals.

Do not use pipe dope or other sealants on threads. Teflon

tape must be used on the threads of the 1” NPT inlet and outlet, the brine line

connection at the control valve, and on the threads for the drain line connection. Teflon

tape is not used on the nut connections or caps

because “O” Ring seals are used. The nuts and caps are designed to be unscrewed or tightened by hand or with the special plastic Service

Wrench, #CV3193-02. If necessary, pliers can be used to unscrew the nut or cap. Do not use a pipe wrench to tighten nuts or caps. Do not

place screwdriver in slots on caps and/or tap with a hammer.

SITE REQUIREMENTS

• water pressure – 25-100 psi • current draw is 0.5 amperes

• water temperature – 33-100°F (0.5-37.7°C) • the plug-in transformer is for dry locations only

• electrical – 115/120V, 60Hz uninterrupted outlet

• the tank should be on a firm level surface (above or below grade)

1. STANDARD INSTALLATION CONFIGURATION: There are four different types of regeneration configurations detailed in this

manual: Standard, Clean Water Regeneration, AutoFlush, and Clean Water Regeneration with AutoFlush. The following illustrations

display a standard installation while the following pages display additional installation configurations.

WELL WATER INSTALLATION MUNICIPAL INSTALLATION

Bypass Valve Installation

2. STANDARD INSTALLATION WITH

AUTOFLUSH:

The optional AutoFlush kit can be utilized to open the bottom drain automatically. This is operated by using a No Hard Water Bypass (NHBP)

motorized valve and a drive from the control valve. The NHBP can be triggered to open by time and will automatically flush the tank of

debris. This is recommended in some well water conditions where heavy loading of the membranes is likely to occur.

For systems with AutoFlush, follow the instructions accompanying the NHBP. Make sure the drain receptacle can adequately handle the

flow from this line.

AUTOFLUSH INSTALLATION

CAUTION: Never insert a drain line into a drain, sewer line, or trap. Always allow an air gap between the drain line and the

wastewater to prevent the possibility of sewage being back-siphoned into the conditioner.

NOTE: When a NHWB is used in an AutoFlush installation, it is necessary to reverse the wires connected to the board. See the

"Configuring Wires for AutoFlush Connection" section for instructions to confirm or change the wire orientation.

*See additional programming settings section on pages 29-30 of this manual for more information regarding this installation.

The following parts are required for this

installation but are not included with the unit.

• Lower tank shut-off valve

• Spring Assisted Check valve

• No Hard Water Bypass (activated during

regeneration). CV3070FM

INSTALLATION

Installation

3. CLEAN WATER REGENERATION

For installations with a high fouling potential, a back flush surge tank and/or a No Hard Water Bypass on the inlet is recommended.

During regeneration, the three way valve will close the normal service inlet and open the inlet from the back flush surge tank. The back

flush surge tank supplies clean, treated water for regeneration. A 50 gallon (total volume) or larger Storage Tank is required. A minimum

of 25 gallons of stored water is required to regenerate the unit.

CLEAN WATER REGENERATION INSTALLATION

The following parts are required for this

installation but are not included with the unit.

• Lower tank shut-off valve

• Spring Assisted Check valve

• No Hard Water Bypass (activated during

regeneration). CV3070FM

CAUTION: The backflush surge tank must be sized to provide enough water for the entire regeneration whether an auto flush kit is

installed or the chlorine generator option is used.

*See additional programming settings section on pages 29-30 of this manual for more information regarding this installation.

4. CLEAN WATER REGENERATION WITH AUTOFLUSH

For installations with a high fouling potential, a back flush surge tank and/or a Separate Source Regeneration Valve (SEPS) or three way

valve on the inlet is recommended. During regeneration, the three way valve will close the normal service inlet and open the inlet from

the back flush surge tank. The back flush surge tank supplies clean, treated water for regeneration. A 50 gallon (total volume) or larger

Storage Tank is required. A minimum of 25 gallons of stored water is required to regenerate the unit.

For systems with AutoFlush, follow the instructions accompanying the NHBP. Make sure the drain receptacle can adequately handle the

INSTALLATION

Installation

INSTALLATION

1. The distance between the drain and the water conditioner should be as short as possible. (See Step 8)

2. It is not recommended to install any water conditioner with less than 10 feet of piping between its outlet and the inlet of a water

heater.

3. Do not locate unit where it or its connections (including the drain and overflow lines) will ever be subjected to room temperatures

under 33°F.

4. Do not subject the tank to any vacuum, as this may cause an “implosion” and could result in leaking. If there is a possibility a vacuum could

occur, please make provision for a vacuum breaker in the installation.

5. Installation of a 5 micron pre-filter is recommended before the UF Filter. This will ensure that larger particles will not prematurely foul

the membrane.

6. INLET/OUTLET PLUMBING: Be sure to install Bypass Valve onto main control valve before beginning plumbing. If it is desired to

bypass outside hydrants, a cold water kitchen sink, or other locations, provisions should be made at this time. Install an inlet shutoff

valve and plumb to the unit’s bypass valve inlet located at the right rear as you face the unit. There are a variety of installation fittings

available. They are listed under the Installation Fitting Assemblies section of the manual. When assembling the installation fitting

package (inlet and outlet), connect the fitting to the plumbing system first and then attach the nut, split ring and “O” Ring. Heat from

soldering or solvent cements may damage the nut, split ring or “O” Ring. Solder joints should be cool and solvent cements should be set

before installing the nut, split ring and “O” Ring. Avoid getting solder flux, primer, and solvent cement on any part of the “O” Rings, split rings,

bypass valve or control valve. If the building’s electrical system is grounded to the plumbing, install a copper grounding strap from the inlet to

the outlet pipe. Plumbing must be done in accordance with all applicable local codes.

7. INSTALLING GROUND: To maintain an electrical ground in metal plumbing of a home’s cold

water piping (such as a copper plumbing system), install a ground clamp or jumper wiring. (See

drawing to the right.)

8. CONTROL VALVE DRAIN LINE: First, be sure that the drain can handle the backwash rate of the

system. Solder joints near the drain must be done prior to connecting the drain line flow control fitting.

Leave at least 6” between the drain line flow control fitting and solder joints. Failure to do this could cause

interior damage to the flow control. Install a 1/2” I.D. tube to the Drain Line Assembly in accordance with

plumbing regulations or discard the tubing nut and use the 3/4” NPT fitting for rigid pipe (recommended).

If the backwash rate is greater than 7 gpm, use a 3/4” drain line. Where the drain line is elevated but

empties into a drain below the level of the control valve, form a 7” loop at the discharge end of the line

so that the bottom of the loop is level with the drain connection on the control valve. This will provide

an adequate anti-siphon trap. Piping the drain line overhead <10 ft is normally not a problem. Be sure

adequate pressure is available (40-60 psi is recommended). Where the drain empties into an overhead sewer line, a sink-type trap must be used

with appropriate air gap (see drawing). Run drain tube to its discharge point in accordance with plumbing codes. Pay special attention to codes

for air gaps and anti-siphon devices.

NOTE: Drain line nut will not be supplied for units having a backwash rate greater than 7 gpm.

. BOTTOM OF TANK DRAIN CONNECTION: At the bottom of the tank is a 1” male threaded connection

fitting. This connection should be fitted with a ball valve. IMPORTANT – the 1” connection is wide open and will

require a ball valve. A drain line should then be run to the nearest drain location. The ball valve is in the closed

position and opened manually to periodically blow the tank down of debris. This should be done manually at

least once per month or if a pressure drop is noticed across the system.

NOTE: The manufacturer does not include the ball valve or drain line – this needs to be supplied and installed

by the dealer or installer.

10. CONFIGURING CONNECTION WIRES FOR AUTOFLUSH

In order to use the NHWB in an AutoFlush con gura on, it is  rst required to reverse the orienta on of the wires in the plas c

connector.

Step 1: Posi on the end of the connector so that the "ears" are facing up (see illustra on below). Con rm that the wire on the le is

white. This is the standard orienta on. Flip the connector over.

Step 2: Using a thin tool (a  at blade or thumbtack), press gently on the middle of both of the metal terminals while pulling down

slightly on the wires. The wires will release from the plas c connector.

Step 3: Reverse the orienta on of the wires and slide both terminals back into the plas c connector. Con nue sliding in wires un l

they click into place.

While looking at the front of the connector (the "ear" side), the white wire will now be on the right. The NHWB is now

correctly con gured for use in an AutoFlush installa on.

11. CONNECTING NO HARD WATER BYPASS (NHWB) TO BOARD

For a No Hard Water Bypass used in a Clean Water Regenera on con gura on, connect to the "Drive 2" (Yellow) molex

connector. Ensure that the wires are in the Standard Con gura on (white on le ).

For a No Hard Water Bypass used in an AutoFlush con gura on, connect to the "Drive 1" (Brown) molex connector. Ensure that the

wires are in the "AutoFlush" Con gura on (white on right).

Programming Procedures

STARTUP INSTRUCTIONS

The system regeneration sequence for a Standard Installation configuration is in the following order. To change the cycle order, consult

the unit’s Dealer Manual or contact the manufacturer. Please see page 29 for sequences for Autoflush and Clean Water Regeneration

configurations.

Standard Installation Regeneration Sequence:

1. Backwash (2 minutes)

2. Rinse (1 minute)

The system is now ready for filling with water and for testing.

1. With the UF Filter Control Valve in bypass mode and unplugged (Fig. 2 on page 4) turn water on slowly. Water will fill system (not the

membrane tank) including the pre-filter and post storage tank if used. Run water preferably at a laundry sink or tub faucet and allow

plumbing to clear. Check for any leaks at this time in newly installed plumbing.

2. With the UF Filter Control Valve in bypass mode (Fig. 2 on page 4) plug control valve transformer into a permanent 110 volt outlet.

The valve should be in normal operating mode where the display shows either time of day or gallons remaining. Press and hold the

�� button until the motor starts. The display will indicate the unit is in the regeneration mode. Release the button.

3. The unit is now in backwash position as indicated on the control valve screen. Do not turn the water on.

4. Push �� button to advance the control valve to the rinse position. Once the valve enters the rinse position, unplug from receptacle.

Leaving the valve in this position, open the inlet bypass valve to the system slowly. This will allow water to enter the tank slowly and

flush the air to the drain. Once system is full, a steady stream of water will be observed at the drain. Open inlet bypass valve completely

(Fig. 3 on page 4) and allow water to drain for 20 minutes. This will allow for proper flushing of the membrane and any preservatives

used in the manufacturing and storage process.

5. Plug unit back into the receptacle.

6. Push �� button and system will return to the normal service position.

7. Again, follow steps 2–6 with the bypass inlet valve open. This will allow for any additional air to be dispelled from the system. It is not

necessary to flush for 20 minutes again as in step 4. When or if no air is observed at the drain, proceed to step 8.

8. Advance control valve to the service position. Upon returning to the service position, open the outlet valve of the bypass to the normal

operating position.

NOTE: Bypass valves should be in the normal operation position. (Fig.1 on page 4).

9. Open a faucet at a laundry sink or at a bath tub. Water will now be flowing through the UF filter system. Run system until water is

clear.

NOTE: If a back flush tank is being used, this will need to be isolated during startup to ensure that no disinfection chemicals enter the

tank. This could cause premature failure of the tank.

NOTE: If a SEP (Separate Source Regen Kit) or a NHBP (No Hard Water Bypass Kit) will be used, these should be left in the normally service

position and disconnected during start up.

NOTE: If an Auto Flush Kit is being used, it should be in the normally closed position during start up.

Start-up Procedures

OPERATING DISPLAYS AND MAINTENANCE

1. GENERAL OPERATION: When the system is operating, one of six displays may be shown and will alternate with the installing dealer’s name

and phone number for future service (if set). Pressing NEXT will alternate between the displays.

1. Time of Day Screen: Displays the current time of day, the day of the week, and flow rate.

2. Flow Rate Screen: Displays the current treated water flow rate through the system in Gallons Per Minute.

3. Vacation Mode Screen: Allows the system to be “shut down” when there will be no water usage for an extended period of time.

4. Capacity Remaining Screen: Displays the amount of gallons of treated water remaining until the system triggers a regeneration.

5. Days to a Regen Screen: Displays the number of days until the system triggers a regeneration. Based on the days override value.

6. Dealer Name Screen: Displays dealer specific name and phone number. This scrolling display will only appear if set by the dealer.

If the system has called for a regeneration that will occur at the preset time of regeneration, the words “REGEN TODAY” will appear on the display.

If a water meter is installed, “GPM” flashes on the display when water is being treated, indicating gallons per minute flowing through the system.

2. VACATION MODE: This feature may be used to “shut down” the system for a period of time by preventing the unit from regenerating. The

manufacturer has factory set “OFF” as the default. Turn feature “OFF” or “ON” using the

+ or – buttons. When turned “ON”, the unit will remain

in Vacation Mode until it is exited. There are two ways that a unit can exit Vacation Mode:

Manually: The user may manually exit Vacation Mode by changing the setting from “ON” to “OFF”. Once switched off, a delayed

regeneration will queue for that night. Vacation mode may also be manually exited by holding the REGEN button to force an immediate

regeneration.

Automatically: The unit will automatically exit Vacation Mode once water usage has resumed. After fifty gallons of water is used, the unit

will set to resume normal operation and a delayed regeneration will queue for that night.

NOTE: In some instances, if a regeneration has been queued and the unit is taken out of Vacation Mode (manually or automatically),

the unit will trigger an immediate regeneration instead of a delayed regeneration. For example, if the unit’s maximum Days

Between Regeneration is reached while the unit is in Vacation Mode, an immediate regeneration will trigger as soon as the unit

is taken out of Vacation Mode.

CAUTION: Depending on the severity of water conditions and the length of no water usage, it may not be recommended to use this

feature. Please contact dealer or manufacturer for more information.

3. Regeneration Mode: Standard UF Filters are set to regenerate once a day. This is a short (2

minute) back flush of the membrane. If water is used at this time, it may be possible to notice

untreated water in the system. If this becomes an issue please contact dealer as options are

available to alleviate this. When the system begins to regenerate, the display will include

information about the step of the regeneration process and the time remaining for that step

to be completed. The system runs through the steps automatically and will reset itself to provide

treated water when the regeneration has been completed.

4. MANUAL REGENERATION: Sometimes there may be a need to regenerate a unit before the control

valve calls for it. This may be needed if a period of heavy water use is anticipated or when the system has been

operating without salt.

• To initiate a manual regeneration at the next preset regeneration time, press and release the REGEN

button. The words “REGEN TODAY” will flash on the display to indicate that the system will regenerate

at the scheduled regeneration time (see the Programming Procedures section). If you pressed the

REGEN button in error, pressing and releasing the button again will cancel the command.

• To initiate a manual regeneration immediately, press and hold the REGEN button for three seconds.

The system will begin to regenerate immediately. This command cannot be canceled.

On Standard UF Filters once a manual regeneration is initiated, the unit will proceed to the backwash position. In this position a two

minute flush to the drain will occur. This backwash allows for flushing of particulates from the membrane to the drain. Once this is

complete, the unit transfers to a one minute rinse. This rinses the tank of these same particles.

5. POWER LOSS AND BATTERY REPLACEMENT: If an extended power outage occurs, the control

valve will retain the time of day settings until the board’s battery is depleted. Once the battery is

depleted, the display will appear dark and absent of any information. If this occurs, following these steps

will determine if the problem is a low battery or a board failure.

To determine if the battery is depleted:

1. Remove valve cover. Disconnect power from PC Board at the four pin connector at the bottom

of the board.

2. Wait five minutes for board to de-energize. Remove battery with a non-conductive/non-metallic

material. Reference the Parts Breakdown section of this manual for location.

3. Wait five minutes for board to de-energize.

4. With the battery out, re-connect the power supply to the board. The board’s display should

begin to show information.

This indicates that the board is operating correctly. If the display does not work, call installing dealer for service.

5. To replace with new battery, unplug transformer from outlet. Install a 3 volt Lithium Coin Cell type 2032 battery, available at most

stores. Plug unit back into outlet.

It is important to replace the battery with the valve unplugged to avoid causing a short and potentially ruining the board.

6. Reset the time of day (see programming procedures) and initiate regeneration (see operating displays and maintenance).

If these procedures do not remedy the problem, please consult the installing dealer for service.

6. AUDIBLE ALARM: This control valve is equipped with an audible alarm and visual alarm. This alarm is set by the installing dealer and is used to

warn the owner of possible valve errors or other issues.

To turn off alarm: If the audible alarm sounds, press any button on the face of the control valve to turn off and call the dealer for service.

7. ERROR MESSAGE: If the word “ERROR” appears and flashes alternately with the dealer name and phone

number, record the ERROR number and contact your servicing dealer promptly. This indicates that the control

valve was not able to function properly.
