Successful Application
Any filter media may havespecificlimitations and/or requirements forsuccessful application. Consult with technical
services when selecting filter media for this system and the specific application.
Time of Regeneration
Periodically the control valve will go through a backwash cycle. This cycle is factory preset to 1:00 A.M. flushing the
accumulated sediment and/or precipitant to the drain. After the backwashing process the unit is now prepared for the
next period of service.

Water Supply
This filter will function properly when the water supply is furnished by a jet pump, submersible pump, variable
speed (constant pressure) pump or community water supply. As with all other filter systems, however, it is
imperativethatthewellpumpprovidesenoughflowrateforthefiltertoadequatelybackwash. Toensuresufficient
backwash flow rate, the following pumping rate test should be performed prior to installing the PIF1. Backwash
flow rate required may vary from the installed DLFC depending on the media used with the filter.
1. Make certain no water is being drawn in the house.
2. Open spigot nearest pressure tank.
3. When well pump starts, close spigot and measure time (in seconds) to refillpressure tank (well pump
turns back off). This is Cycle Time.
4. Using a container of known volume, draw water from pressure tank and measure how many gallons
until the pump turns back on again. This is Draw Down.
5. Calculate pumping rate by dividing draw down by cycle time and multiplying by 60.
Draw Down (gallons)
X
60
=
Pumping Rate (gallons per minute)
Cycle Time (seconds)
Example: Draw down is 8 gallons
Cycle time is 65 seconds
Location Considerations
The proper location to install the PIF1 will ensure optimum filter performance and satisfactory water quality. The
following factors should be considered in selecting the location of this system.
1. The PIF1 must be installed after the pressure tank (private well system only).
2. 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
specifications). An air gap should be provided between the PIF1 drain line and plumbing drain.
3. All water conditioning equipment should be installed at least 10’ prior to the water heater. Water
temperatures exceeding 100°F can damage the internal components of the control valve and filter
tank. An expansion tank may need to be installed in the line to the water heater to allow for thermal
expansion and comply with local plumbing codes.
4. Water pressure must not exceed the range of 25 - 100 psi.
5. The system must not be subject to freezing temperatures.
6. The control valve requires 115/120 V, 60 Hz electricity from an outlet that is not wired to a switch.
7. Never install a cartridge type filter prior to the PIF1. Any cartridge or in-line filter (if desired) may be
installed after the PIF1 system. This willprevent restricting the water flow and pressure available for
backwash.
8. Appliances requiring extended periods of continuous or high flow water use (i.e. geothermal heat
pumps, swimming pools, lawn irrigation, outside hose bibs, etc.) should bypass the filter.

GENERAL INSTALLATION & SERVICE WARNINGS
The water conditioner is 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
used on black “O” Rings. This will allow ease of installation and decrease chance of rolling from the bypass and
tank connections. 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 may be used as required. Teflon®tape is not
used on any connection where “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.
Make sure the filter is not installed backwards. The filter will not function properly if installed backwards and filter
media may be forced into the service lines. Arrows molded into the valve body and red handles of the bypass
indicate the direction of flow.
The PIF1 has a check valve (OV32) installed in the inlet of the control valve. This check valve will prevent hot
water expansion in the plumbing. An expansion tank must be used on the water heater supply line to
allow for thermal expansion.
All local plumbing codes must be followed.

The bypass valve is used to isolate the control valve from the plumbing system's water pressure in order to
perform controlvalverepairs or maintenance.The1" 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 interchangeableplug valves that areoperated 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. 2).
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. 3).
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. 4) .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 softener being in regeneration could cause a siphoning
of brine into the building. If water is available on the outlet side of the softener it is an
indication of water bypassing the system (Fig. 5)

STEP 1: Unpack filter unit, making sure to remove entire contents of the shipping container prior to disposal.
STEP 2: Withthefilterunitintheuprightposition,removethecontrolvalvefromthemineraltankbeingcareful
to not pull the distributor out of the gravel at the bottom of the tank. If the filter model has a “-DH”
suffix, do not remove the control valve. Just remove the tank dome hole plug.
STEP 3: Ifthecontrol valve wasremoved,coverthe top of the distributortubewiththeincludedredcap.Using
the included blue media funnel, pour filter media(s) into the mineral tank. If using multiple filter
media types, load in the order of heaviest (most dense) to lightest (least dense). 14” of space MUST
be left empty at the top of themineral tank to allow for media bed expansion during backwash and to
prevent filter media from being discharged through the drain line.
STEP 4: Use a garden hose or bucket to fill the media tank with water.
IMPORTANT: Carbon, Filter Ag, Zeolite and Greensand Plus must be soaked for at least 2
hours prior to submitting it to full backwash flow rate to prevent loss of media to drain.
STEP 5: Clean mineral tank threads to remove any filter media. If the control valve was removed, remove red
cap from distributor tube and reinstall control valve by threading it securely onto the mineral tank.
Otherwise simply replace the tank dome hole plug. (O-ring seal: HAND TIGHTEN ONLY!)
STEP 6: Shutoff allwateratmainsupply. Onprivatewellsystem,turnoffpowertopumpanddrainpressure
tank. Make certain pressure is relieved from complete system by opening nearest faucet to drain
system. SHUT OFF FUEL / ELECTRICAL SUPPLY TO WATER HEATER.
STEP 7: Plumb the water supply line to the unit's bypass valve inlet, located at the right rearas you face the
unit. There are a variety of installation fittings available. They are listed under Installation Fitting
Assemblies, pages 23-25.Whenassembling theinstallation fittingpackage(inletand outlet), connect
the fitting to the plumbing system first and then attach the nut, split ring, and "O" Ring. Heat from
soldering orsolventcements may damage thenut, split ring,or "O" Ring. Solderjoints shouldbecool
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
controlvalve.Ifthebuilding'selectricalsystemisgroundedto theplumbing,installacoppergrounding
strap from the inlet to the outlet pipe. Plumbing must be done in accordance with all applicable local
codes. MAKE CERTAIN WATER ENTERS THROUGH INLET AND DISCHARGES THROUGH
OUTLET.
STEP 8: Apply thread tape to DLFC Assembly. Remove drain line flow control (DLFC) retainer clip (Figure
6, Page 7) and remove the DLFC assembly from the valve body, (Figure 6, Page 7). Apply thread
tapetothreads.Slidedrainfittingcompressionnutontoprovideddraintubingandplacethetubeinsert

nut onto the thread taped elbow. Reinsert DLFC assembly into the valve body, making certain it is
FULLY inserted before replacing the retaining clip.
STEP 9: Install drain line. Use the provided ½” I.D. polyethylene tubing (DO NOT USE FLEXIBLE VINYL
TUBING!) to run drain line from controlvalve DLFC fitting(Figure6,Page 7) to floordrain or sumppit
capable of handling the backwash rate of the filter (refer to specifications and flow rate on page 17)
or discard the compression fitting and use the ¾” NPT fitting to connect a rigid pipe drain line . If
backwash flow rate is greater than 7.5 gpm, use existing NPT connector with rigid drain line. There
must be an air gap at the end of the drain line to prevent siphoning of wastewater. Length of drain
line should be 15’ or less. AVOID OVERHEAD DRAINS.

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 (depending on how it is programmed). 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
systemgoesthrougharegenerationcycle.Thethirddisplayiscurrentflowingal/min.Theusercanscrollbetween
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 constant for 5 minutes then continue to scroll. The conditional screens will take
precedence over the scrolling and the conditional conditions will apply. 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 manualregeneration. There may bea periodof heavy water usage becauseofguests or a heavy laundry day.
To initiate a manual regeneration at 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
aredesired within 24 hourperiod,press /release REGEN button. REGEN TODAY will flash on screen.Pressand
hold REGEN button until valve initiates an immediate regeneration.
General Operation

11
1) If your unit contains activated carbon, youshould replace thecarbon and gravel underbed at least every
three years. Replacement may be required soonerif the taste and odor being removed begins to reappearin
the treated water or you experience increasing pressure drop that is not resolved by increasing the frequency
of backwashing.
2) Filter Ag, Zeolite and Filter Sand will last indefinitely. It may be necessary to replace them if you experience
increasing pressure drop that is not resolved by increasing the frequency of backwashing orif water quality
diminishes due to contaminant bleed through.
3) Iron Pro media or calcite will need replenished with neutralizer media (N05, MPH30 or C05P) regularly in low
pH water. Mark the side of the mineral tank at installation so the drop in media level may bemonitored by
shining a bright light behind the mineral tank. Add mediaif the level has dropped by more than three inches.
4) Greensand Plus or KataloxLight should be replaced when iron reappears in the treated water and
backwashing does notimprove the water quality or excessive pressure loss isexperienced.
5) Verify the unit draws air during the REGENERANT DRAW cycle at least every 12 months. Clean orreplace
the air check valve (OV15HT) and/or the injector (CV3010-1I) and/or injector screen (CV3177-01), if needed.
TO REPLENISH OR REBED MEDIA:
1) Pressure must be relieved on the system by placing the Bypass Valve in the “Bypass” position (Figure 3,
Page 5) and initiating a manual regeneration (section 3, page 10).
2) Unplug the Control Valve fromthe electrical outlet to preventit from advancing automatically.
3) Disconnect the Control Valve fromtheBypass Valve. If the unit has a “-DH” suffix in the model number and it
only needs topped up with neutralizer media, DO NOT disconnect from the bypass valve.
4) Disconnect the Drain Line from the Control Valve
5) Unscrew Control Valve from Mineral Tank (IF REBEDDING ONLY! Remove the distributor).If the unit
has a “-DH” suffix in the model number and it only needs topped up with neutralizer, DO NOT remove the
control valve, just unscrew the dome hole plug instead.
6) Siphon water from Mineral Tank (IF REBEDDING ONLY! Remove existing media and gravel).
7) (IF REBEDDING ONLY! Rinse Mineral Tank and replace distributor, making certain that the
distributor basket sits in the center of the tank bottom.)
8) If the control valve was removed, cover the top of the distributor tube to prevent media entering the tube
during filling. Using a funnel, pour filter media(s) into the mineral tank. (IF REBEDDING ONLY! Begin
loading the tank with the gravel underbed. Filling the Mineral Tank 1/3 with water before loading
gravel will cushion the fall and ensure even distribution of the gravel and media. If using multiple
filter media types, load in the order of heaviest {most dense} to lightest {least dense}.) 14” of space
MUST be left empty at the top of the mineral tank to allow for media bed expansion during backwash and to
prevent filter media from being discharged through the drain line.
9) Use a garden hose or bucket to fill the media tank with water.
10) Clean mineral tank threads to remove any filter media. If control valvewas removed,uncover distributor tube
and reinstall control valve by threading it securely onto the mineral tank. “-DH” models that were only topped
up with neutralizer on need thedome hole plug replaced. O-ring seal; HAND TIGHTEN ONLY in both cases!
Maintenance

12
11) If control valve was removed, attach bypass valve to control valve body.
12) If control valve was removed, reattach Drain Line to Control Valve (Figure 6, Page 7).
13) IMPORTANT! Carbon, Filter Ag, Zeolite and Greensand Plus must be soaked for at least 2 hours
prior to submitting it to full backwash flow rate to prevent loss of media to drain.
14) Gradually turn the INLET side knob of the bypass valve counterclockwise not more than ½ way (45
degrees) to the “Service” position (Figure 2, Page 5) allowing unit to pressurize slowly. Check for leaks
and correct as needed. Any air trapped in the media bed should begin purging to the drain and water
should begin flowing to the drain.
15) Once the air is purged, gradually turn the INLET knobof the bypass valve counterclockwise until it is fully
in “Service” position (Figure 2, Page 5). Then turn the OUTLET knob of the bypass valve counter-
clockwise until it is fully in the “Service” position (Figure 2, Page 5). and leave the control valve in
“Backwash” position for at least 10 minutes or until water flowing from the drain line runs clear;
whichever is longer.
16) Plug the transformer intothe electrical outlet. Press the “REGEN” button to advance the control valve to
the “RINSE” cycle. Another count-down timer will appear in the time-of-day position, “RINSE” will be
shown in the lower middle of the display and “REGEN” appears in the middle left of the display. Allow
the rinse cycle to complete and the filter will return to service mode automatically.
