Description of the system
The PNR1 system includes a mineral tank (with gravel, distributor and nitrate selective anion resin), brine tank
(with salt shelf, brine well, brine tank lid and safety brine valve), a mineral tank with digital backwashing control
valve with bypass valve, plumbing adapters, drain line and brine line.
Successful Application
The PNR1 system is designed to reduce nitrate, sulfate and chloride levels in potable water through anion
exchange. Water softener salt is required to regenerate the anion resin, but the PNR1 is NOT A WATER
SOFTENER. It exchanges chloride (taken from the brine used for regeneration) for nitrate, sulfate and fluoride
anions. The water being supplied to the PNR1 system must be; soft, iron free, manganese free, tannin free,
have less than 0.5 ppm chlorine and be filtered to 5 microns. Pre-treatment equipment is always required and
post-treatment with reverse osmosis may be required if TDS level exceeds 500 ppm after treatment or if a salty
taste occurs when used in combination with a softener due to the addition of sodium and chloride to the drinking
water.
Time of Regeneration
Periodically the control valve will go through regeneration. Regeneration is factory preset to 3:30 A.M. The time
of regeneration may be changed if needed (see programming procedures on pages 9 - 10).
Location Considerations
The proper location to install the system will ensure optimum performance and satisfactory water quality. The
following factors should be considered in selecting the location of this system.
1. The system must be installed after the pressure tank (private well system only).
2. The system should be installed after any other water treatment equipment except reverse osmosis.
3. If chlorine is present in the supply water a whole house carbon filter should be installed before the
system.
4. The system must not be subject to freezing temperatures.
5. Ensurethatanyin-linefilterinstalledpriortothesystemdoesnotrestrictthefloworpressurerequired
to backwash the system.
6. The system should be installed as close as possible (preferably within 15’) to an adequate floor or
laundry drain capable of handling the backwash cycle volume and flow rate (refer to unit
specificationsonpage11).Anairgapshouldbe providedbetweenthedrain lineandplumbingdrain.
7. All water conditioning equipment should be installed at least 10’ prior to the water heater. Water
temperaturesexceeding100°Fcandamagetheinternalcomponentsofthecontrolvalveandmineral
tank. An expansion tank may need to be installed in the line to the water heater in order to allow for
thermal expansion and comply with local plumbing codes.
8. Appliances requiring extended periods of continuous or high flow water use (i.e. geothermal heat
pumps,swimmingpools,lawnirrigation,outsidehosebibs,etc.)shouldbypassallwater conditioning
equipment unless the equipment has been specifically designed for that purpose.

GENERAL INSTALLATION & SERVICE WARNINGS
The systemis not designed to support the weight of plumbing.
Do not use Vaseline, oils, other hydrocarbon lubricants or spray silicone anywhere. A silicone lubricant may be
usedon 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 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, not included). 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.
NOTE: If the plumbing system is used as the ground leg of the electric supply, continuity should be maintained
by installing ground straps around any non-conductive plastic piping or bypass used in the installation.
Makesure the system is not installed backwards. The systemwillnot function properly if installedbackwards and
anion resin may be forced into the water lines. Arrows molded into the valve body indicate the direction of flow.
Site Requirements
● water pressure -- 25-100 psi (1.7 –6.9 bar)
● water temperature -- 33-100°F (0.5-37.7°C)
● electrical -- 115/120 V, 60 Hz uninterrupted outlet dry locations only
● the tank should be on a firm level surface

STEP 1: Carefully remove all components from packaging. DO NOT DISCARD PACKAGING until all
nitrate reduction system components and fittings have been located.
STEP 2: Usingtheintegrated coupling nuts, attach the bypass valve tothe inlet/outlet of the controlvalve
and put handles in the bypass position (Figure 2).
STEP 3: Place unit at desired installation position.
STEP 4: Shut off water at main supply. Relieve pressure by opening nearest faucet. On private well
systems, turn off power to pump and drain pressure tank. SHUT OFF POWER OR FUEL
SUPPLY TO WATER HEATER.
STEP 5: Cut main supply line as required to fit plumbing to inlet and outlet of bypass valve. DO NOT
PLUMB INLET AND OUTLET BACKWARDS. Piping should be supported. Do not apply heat
to any fitting attached to the bypass or control valve.
STEP 6: Use the provided polyethylene tubing (NO VINYL TUBING) to run drain line from control valve
drain fitting (Figure 2) to floor drain or sump pit capable of handling the backwash rate of the
system (refer to specifications on Page 11). THE DISCHARGE END OF THE DRAIN LINE
MUST BE FIRMLY SECURED! There must be an air gap at the end of the drain lineto prevent
siphoning of wastewater and meet plumbing code. Total length of drain line should be 15’ or
less. AVOID OVERHEAD DRAINS.

STEP 8: If desired, install overflow tubing (not provided) from overflow elbow on brine tank (Figure 3) to
floor drain. Tubing must be lower than the overflow elbow at all times. DO NOT CONNECT
DRAIN LINE FROM SYSTEM CONTROL VALVE TO BRINE TANK OVERFLOW. DO NOT
CONNECT BRINE TANK DRAIN LINE TO THE SYSTEM DRAIN LINE.
STEP 9: Plugthe transformer into an un-switched electrical outlet. Ensure the control valve is in “Service”
mode (display will alternate between time, gallons remaining, days remaining and flow rate).
STEP 10: Place the bypass valve in the “Service” position (refer to Figure 4a, Page 7) and open main
supply valve or turn on power to pump on private well systems. Allow the unit to fill with water
and pressurize, then place the bypass valve in the “Bypass” position.
STEP 11: Add water in the brine tank to slightly above the top level of the salt grid (approx. 5 - 6 gallons
for units without a salt grid). DO NOT ADD SALT TO THE BRINE TANK AT THIS TIME.

STEP 12: With the bypass valve in the “Bypass” position (refer to Figure 4a, Page 7), press and hold the
REGEN button until the motor starts. Then use the REGEN button to advance the control valve
to the BACKWASH cycle to release pressure and purge air from the mineral tank.
STEP 13: Refer to Figure 4, Page 7 for bypass valve operation. Rotate the INLET knob of the bypass
valve slowly to the “Service” position (Figure 4a). If any air spurts or any resin is expelled to the
drain, stop turning the knob until only water flows to the drain, then continue turning the knob
fully to the “Service” position.
STEP 14: When all air has been purged from the system and only water is running to the drain, turn the
OUTLET knob of the bypass valve to the “Service” position also. Allow the system to backwash
for a few minutes or until the drain water runs clear.
STEP 15: Using the REGEN button, advance the control valve to the REGENERANT DRAW DN
(downflow brine draw) cycle. Verify that the water level in the brine tank is slowly dropping (less
than ½ gpm). Allow water level to drop below the top of the salt grid before continuing. If the
water level does not drop, refer to page 18 for Troubleshooting. After verifying water level is
dropping, use the REGEN button to advance past the BACKWASH 2, RINSE AND 5 second
FILL cycle to the normal service display.
ADD SALT TO BRINE TANK NOW. Any typeof water softener salt may be used.
STEP 16: Check for leaks and correct as necessary.
STEP 17: Turn power or fuel supply back on to water heater.

The bypass valve is 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 installbypass 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 nitrate reduction system or filter. During the regeneration cycle this
position provides regeneration water to the unit, while also providing untreated water to
the distribution system (Fig. 4a).
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. 4b).
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. 4c) .This allows the service technician to draw brine and perform other tests
without the test water going to the building.
NOTE: The system must be run through a rinse cycle 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 system being in regeneration could cause a siphoning
of brine into the building. If water is available on the outlet side of the system it is an
indication of water bypassing the system (Fig. 4d)

USER DISPLAYS
When the system is operating, one of several displays may be shown. Pressing NEXT will alternate between the
displays. One of the displays is the current time of day. The second display shows days to a regen/gallons
remaining. Days To A Regen is the number of days left before the system goes through a regeneration cycle.
Capacity remaining is the number of gallons that will be treated before the system goes through a regeneration
cycle. Thethird display is currentflow in gal/min. The user canscroll between the displays as desired by pushing
NEXT or display will scroll automatically. When water is being treated (i.e. water is flowing through the system)
the word "GPM" flashes on left side of display when other than flow rate is displayed. User screens will
continuously scroll, switching views every 3 seconds. If the screens are manually scrolled, this screen will remain
constantfor5 minutesthencontinue toscroll. Theconditional screens willtakeprecedenceoverthe scrollingand
the conditional conditions willapply.To manually reduce capacity, press down button while capacity remaining or
days to a regen is displayed.
MANUAL REGENERATION
Sometimes there is a need to regenerate the system sooner than when the system calls for it, usually referred to
as manual regeneration. There may bea period of heavy waterusagebecause of guests or a heavy laundry day.
Toinitiateamanualregenerationat the preset delayed regeneration time, press and release “REGEN”. The words
“REGEN TODAY” will flash in left corner of display as it scrolls through displays to indicate that the system will
regenerate at the preset delayed regeneration time. If you pressed the “REGEN” button in error, pressing the
button again will cancel the request. To initiate a manual regeneration immediately, press and hold the “REGEN”
button for five seconds. The system will begin to regenerate immediately. The request cannot be cancelled. You
must cycle all the way through the cycles to make it stop. PLEASE NOTE: This will reset the meter. Note: If the
salt tank does not contain salt, fill with salt and wait at least two hours before regenerating. If two regenerations
are desired within 24 hour period, press /release REGEN button. REGEN TODAY willflash on screen.Press and
hold REGEN button until valve initiates an immediate regeneration.

line: plugged,
frozen, kinked,
flexible tubing,
overhead
installation,
diameter too small,
longer than 15’
F) Missing BLFC
G) Missing brine stem
H) Worn seals
1) Tighten nuts at either end of brine line
2) Verify brine line is installed correctly
3) Verify system drain line is not connected to
brine overflow elbow or brine overflow drain
line
4) Check for debris in DLFC Assembly, BLFC
Assembly, injector, injector screen
5) Manually put system into Backwash Cycle
(page 8) and unplug the transformer for 30
minutes to dislodge debris from inside the
control valve or disassemble and clean
control valve internal components
6) Resolve issues with the drain line
7) Verify brine line flow control button is not
missing
8) Verify piston brine stem is not missing
9) Replace seal and spacer assembly
Untreated water or
system not using salt
A) System is plugged
into an electrical
outlet without power
or one that is tied to
a switch
B) No salt in the brine
tank
C) Salt in the brine tank
has “bridged”
D) Bypass Valve is not
in “Service” position
or is leaking
E) Obstruction in
control valve
I) Problems with drain
line: : (See letter
“E”in prior section)
F) Control valve
programmed
incorrectly
G) System sized
improperly for actual
service flow rates
H) Faulty or unplugged
drive motor
I) Meter cable
disconnected
1) Verify system has uninterrupted power
2) Fill brine tank with salt
3) Hit the side of the brine tank with rubber
mallet to break any bridging that has
formed in the brine tank
4) Verify bypass is in “Service” position
(Figure 4a, Page 7)
5) Check for debris in DLFC Assembly, BLFC
Assembly, injector, injector screen
6) Manually put system into Backwash Cycle
(page 8) and unplug transformer for 20-30
minutes to dislodge debris
7) Resolve issues with drain line
8) Review control valve programming
9) Verify actual service flow rates required and
compare to system specifications (pages
11)
10) Verify drive motor is connected to control
valve circuit board connector J1 (labeled
“MOTOR”)
11) Verify meter cable (grey cable, 3 pins) is
connected to control valve circuit board
connector J2 (labeled “METER”)

Salty Water
A) Brine tank overfilled
B) Problems with drain
line: (See Letter
“E” in Brine Tank
Overfill section)
C) Rinse cycle is short
D) Salt setting too high
E) Distributor tube
improperly seated
in control valve or is
too short
F) Low water pressure
1) See “Brine tank overfills” section (Page 18)
2) Resolve drain line issues
3) Contact technical support for assistance in
verifying \ adjusting Rinse Cycle length and
Salt Setting
4) Verify proper installation of distributor tube
5) Verify at least 25 psi of line pressure
System leaks to drain
in “Service” position
A) Problem in seal
cartridge assembly
B) Control valve is
jammed or halted
during regeneration
C) Drive cap assembly
is not tightened
properly
1) Replace seals and/or piston if needed
2) Verify control valve is in “SOFTENING”
mode
3) Tighten drive cap assembly
Low water pressure
A) Iron or sediment
build up in system
B) Insufficient pump
capacity
1) Increase backwash frequency by increasing
equivalent hardness setting (page 9)
2) Verify at least 25 psi of line pressure
Display is blank
A) Control valve circuit
board needs reset
B) Transformer is
unpowered,
unplugged or
defective
