REVIEW
GENERAL INSTALLATION
AND SERVICE WARNINGS
WATER QUALITY: If sand or sediment is present in the
water supply, a sediment lter should be installed ahead
of the water softener. Your water softener has been
designed to adequately reduce hardness from levels up
to 100 grains per gallon. Ferrous bicarbonate iron levels
up to 0.5 ppm can also be reduced. This is iron that is
dissolved in water and not visible to the eye in a freshly
drawn sample. After standing in contact with air, the ferrous
iron will become oxidized to the ferric state and start to
precipitate as a reddish brown oc. It can be seen and may
cause discolored water. Air must not come in contact with
water until after it has passed through the water softener.
In some cases, additional treatment equipment may be
needed to treat water having special characteristics, such
as: ferric hydroxide iron, iron bacteria, low pH, tastes and
odors, etc. Consult your dealer if you have any questions.
This water softener is not to be used for treating
water that is microbiologically unsafe or of unknown
quality without adequate disinfection before or after
treatment.
WATER PRESSURE: A minimum of 20 pounds of water
pressure (psi) is required for regeneration. Maximum
100 psi. CAUTION: the softener cannot be subject to a
vacuum due to loss of pressure (such as a water main
break or submersible well pump check valve failure).
WATER TEMPERATURE: The range of water temperature
is 35°F to 100°F. DO NOT install any water softener with
less than 10 feet of piping between its outlet and the inlet
of a water heater.
AMBIENT TEMPERATURE: DO NOT locate softener
where it or its connections (including the drain and
overow lines) will ever be subject to room temperatures
under 33°F.
ELECTRICITY: An uninterrupted 120 volt 60Hz source is
required. Make sure electrical source is not on a timer
or switch. All electrical connections must be connected
according to local codes. The plug-in transformer is for
dry locations only. Surge protection is recommended with
all electrical connections.
DRAIN: All plumbing should be done in accordance with
local plumbing codes. The distance between the drain
and the water softener should be as short as possible.
The pipe size for the drain line should be a minimum of
1/2” (inside diameter of pipe).
SOFTENING: It is recommended that the softener be
installed to soften both the hot and cold water supply. A
separate hard water faucet may be plumbed for drinking
purposes if desired. Outside faucets should be left on
hard water.
BYPASS: A bypass valve (optional accessory) should
be installed so that water will be available if it should be
necessary to shut off the pressure in order to service the
softener.
The control valve, tting and/or bypass are designed to
accommodate minor plumbing misalignments but are
not designed to support the weight of a system or 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 the clear lip seals.
The nuts and caps are designed to be unscrewed or
tightened by hand or with the special plastic wrench
(V3193). If necessary, pliers can be used to unscrew the
nut or cap. Do not use a pipe wrench to tighten or loosen
nuts or caps. Do not place a screw driver in the slots on
caps and/or tap with a hammer.
Do not use pipe dope or other sealants on threads. Use
Teon tape on the threaded inlet, outlet and drain ttings.
Teon tape is not necessary on the nut connection or caps
because of o-rings seals.
After completing any valve maintenance involving the
drive assembly or the drive cap assembly and pistons,
unplug power source jack from the printed circuit board
(black wire) and plug back in or press and hold
REGEN
and
and establishes the service piston position. The display
should ash the software version and then reset the valve
to the service position.
Solder joints near the drain must be done prior to
connecting the drain line ow control tting. Leave at least
6” between the drain line control tting and solder joints
when soldering pipes that are connected on the drain
line control tting. Failure to do this could cause interior
damage to the drain line ow control tting.
When assembling the installation tting package (inlet
and outlet), connect the tting to the plumbing system rst
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 primer and solvent cement on
any part of the o-ring, split rings, bypass valve or control
valve.
Install grounding strap on metal pipes.

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 X-Factor bypass valve is particularly unique in the water treatment industry due to its versatility
and state of the art design features. The 1” full ow bypass valve incorporates four positions, including a diagnostic position that
allows service personal to work on a pressurized system while still providing untreated bypassed water to the facility or residence. Its
completely non-metallic, all-plastic design allows for easy access and serviceability without the need for tools.
The bypass body and rotors are glass lled Noryl® (or equivalent) and the nuts and caps are glass lled 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 ow direction of the water. The plug valves enable the bypass valve to operate in four positions.
OPERATION:
1. Normal Operation Position: The inlet and outlet
handles point in the direction of ow indicated by the
engraved arrows on the control valve. Water ows
through the control valve during normal operation and
this position also allows the control valve to isolate the
media bed during the regeneration cycle. (see gure
1)
2. Bypass Position: The inlet and outlet handles
point to the center of the bypass, the control valve
is isolated from the water pressure contained in the
plumbing system. Untreated water is supplied to the
plumbing system. (see gure 2)
3. Diagnostic Position: The inlet handle points in
the direction of ow and the outlet handle points to
the center of bypass valve, system water pressure is
allowed to the control valve and the plumbing system
while not allowing water to exit from the control valve
to the plumbing. (see gure 3)
4. Shut Off Position: The inlet handle points to the
center of the bypass valve and the outlet handle
points in the direction of ow, the water is shut off
to the plumbing system. If water is available on the
outlet side of the softener it is an indication of water
bypass around the system (i.e. a plumbing connection
somewhere in the building bypasses the system).
(see gure 4)
The working parts of the bypass valve are the rotor assemblies that are contained under the bypass valve caps. Before working on the
rotors, make sure the system is depressurized. Turn the red arrow shaped handles towards the center of the bypass valve and back
several times to ensure rotor is turning freely.
The nuts and caps are designed to be unscrewed or tightened by hand. If necessary a pliers or the service spanner wrench can be
used to unscrew the nut or cap. Do not use a pipe wrench to tighten or loosen nuts or caps. Do not place screwdriver in slots on caps
and/or tap with a hammer.
Refer to page 19 for bypass valve parts diagram and service spanner wrench information.
To access the rotor, unscrew the cap and lift the cap, rotor and handle out as one unit. Twisting the unit as you pull it out will help to
remove it more easily. There are three o-rings: one under the rotor cap, one on the rotor stem and the rotor seal. Replace worn
o-rings. Clean rotor. Reinstall rotor.
When reinstalling the red arrow handles be sure that:
1. The handle pointers are lined up with the control valve body arrows, and the rotor seal o-ring and retainer on both rotors face
to the right when being viewed from the front of the control valve; or
2. Arrows point toward each other in the bypass position.
Since the handles can be pulled off, they could be accidentally reinstalled 180° from their correct orientation. To install the red arrow
handles correctly, keep the handles pointed in the same direction as the arrows engraved on the control valve body while tightening the
bypass valve caps.

(All electrical & plumbing should be done in accordance to all local codes)
1. Place the softener where you want to install it, making
sure it is on a clean, level and rm base.
2. Do all necessary plumbing (inlet to inlet, outlet to outlet,
and drain line to drain). The control valve, ttings and/or
bypass are designed to accommodate minor plumbing
misalignments but are not designed to support the weight
of a system or the plumbing.
3. When assembling the installation tting package (inlet
and outlet), connect the tting to the plumbing system
rst 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 joint should be cool and solvent
cements should be set before installing the nut, split ring
and o-ring. Avoid getting primer and solvent cement on
any part of the o-rings, split rings, bypass valve or control
valve.
4. A jumper ground wire should be installed between
the inlet and outlet pipe whenever the metallic
continuity of a water distribution piping system is
interrupted. Install grounding strap on metal pipes.
5. The drain connection may be made using either 5/8”
polytube (see below) or a 3/4” female adapter. The
polytube insert is shipped attached to the drain line
elbow’s locking clip. Press the insert into the drain line
tubing (tubing not provided). Loosen the nut of the drain
line elbow. Press the 5/8” polytube with insert into the
drain line elbow until it seats on the back of the tting.
Tighten the nut. If soldering, joints near the drain must be
done prior to connecting the drain line ow control tting.
Leave at least 6” between the drain line control tting and
solder joints when soldering pipes that are connected on
the drain line control tting. Failure to do this could cause
interior damage to the drain line ow control tting. 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 softener.
6. The brine rell ow control assembly is installed in an
easy to access rell elbow located on top of the control
valve. The rell ow control assembly is attached to the
control valve with a locking clip. The locking clip allows the
elbow to rotate 270 degrees so the outlet can be oriented
towards the brine tank.
7. Connect the brine line polytubing found with the brine
tank to the brine connection on the control valve. The
control valve has a standard rell elbow to which a 3/8”
exible tube can be connected, see below. Press the
polytube into the brine elbow tting. Make sure the oor
is clean beneath the brine tank and that it is level and
smooth.
8. A 1/2” (inside diameter, not provided) gravity drain line
should be connected to the overow tting on the side of
the brine tank. This overow is in case of a malfunction in
the brine shut off. If the unit is installed where water may
ow in the event of an overow and cause water damage,
connect a length of exible tubing and run to a drain below
the level of the overow. (Do not connect the tubing to
the drain line on the control valve. Do not run tubing
above overow height at any point.)
