INSTALLATION
Installation Fitting Assemblies
1. Installation ttings connect to the control valve or the bypass valve using nuts that only require hand tightening.
Hand tightened nut connections between control valve and installation ttings, control valve and bypass valve, and
bypass valve and installation ttings allow for ease serviceability. Do not use a pipe wrench to tighten nuts on
installation ttings. Hand tighten only.
2. Split ring retainer design holds the nut on and allows load to be spread over the entire nut surface area reducing
the chance for leakage. The split ring design, incorporated into the installation ttings allows approximately 2
degrees off axis alignment to the plumbing system. The installation ttings 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, 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 cements on any part of the o-rings or split rings, bypass valve or control valve. Solvent cements
and primers should be used in accordance with the manufacturer’s instructions.
Slip the nut onto the tting rst, then the split ring second and the o-ring last. hand tighten the nut. If the tting
is leaking, tightening the nut will not stop the leak. Remove the nut, remove the tting, and check for damage or
misalignment of the o-ring.
Do not use the pipe dope or other sealant on threads. Teon tape must be used on the threads of the 1”
NPT elbow and the 1/4” NPT connection and on the threads for the drain line connection. Teon tape is not
necessary on the nut connection or caps because of o-ring seals.
Do not use Vaseline, oils or other hydrocarbon lubricants oanywhere on the control valve or resin tank
assembly. A silicon lubricant may be used on black o-rings, but is not necessary.
Bypass Valve
1. The bypass valve easily connects to the control valve body using nuts that only require hand tightening. Hand
tighten nut connections between control valve and ttings, control valve and bypass valve, and bypass valve and
installation ttings allow for easy serviceability. The split ring retainer design holds the nut on and allows load to
be spread over the entire nut surface area reducing the chance for leakage. The split ring design, incorporated into
the bypass, allows approximately 2 degrees off axis alignment to the plumbing system. The bypass is designed to
accommodate minor plumbing misalignments but is not designed to support the weight of a system or the plumbing.
Avoid getting primer and solvent cements on any part of the o-rings or split rings, bypass valve or control
valve. Do not use pipe dope or other sealant on threads. Teon tape is not necessary on the caps because of
o-ring seals.
Do not use Vaseline, oils or other hydrocarbon lubricants oanywhere on the control valve or resin tank
assembly. A silicon lubricant may be used on black o-rings, but is not necessary.
Connecting Fittings
CAUTION: Care must be used when working with copper tubing. Do not allow the ame from torch to contact any por-
tion of the Valve assembly.
1. Attach 1/2” drain line to drain elbow with insert and nut. Use optional 3/4” drain ttings if drain run
exceeds 25 ft.
2. Do not elevate the drain line over 5’ above the top of the valve (8’ on municipal systems) or to exceed 25’ in
length at either height.
CAUTION: An air gap must be provided upon sewer entry. (Conform to local plumbing and sanitation codes and ordi-
nances).
3. The salt storage cabinet or brine tank provides an overow. Attach 1/2” ID exible plastic tubing to the overow
tting and direct it to the drain. DO NOT connect to the main drain line. Use a separate gravity ow line.

Installation Procedures
Please see page 3 for installation of tting assemblies.
All installation procedures must conform to local plumbing, electrical and sanitation codes and ordinances.
A. Planning Installation
1. It is recommended that outside faucets for lawn
service be on a hard water line, ahead of the softener. This will conserve softened water, save salt
www.Marlo-Inc.com
and prevent lawn damage. If this is not practical,
use the convenient integral bypass valve assembly
during irrigation ows.
2. CAUTION: The inlet water temperature MUST
NOT EXCEED 110° F.
3. DO NOT locate the softener where ambient temperature drops below 40° F.
4. Allow space around the softener for ease of servicing.
5. Softener drain lines must never be solidly connected to the sewer line (always provide an air gap
at the END of the drain line).
6. The drain line must NOT be elevated over 5’ from
the top of the softener on well systems, and 8’ on
municipal water systems.

B. General Installation
1. Turn off the main water supply before making any plumbing connections to existing piping.
2. Move the softener into position, making sure it is on a clean level surface. If shims are needed you may use
those to create a level installation. DO NOT USE METAL SHIMS
3. When installing the unit, be sure to connect the inlet and outlet to the correct ports on the valve. The bypass
valve and the control valve are both marked with arrows that indicate the direction of water ow. If water lines
are reversed resin maybe forced from the water softener and into household plumbing system. Should this
occur, the plumbing system would need to be ushed.
4. Install the bypass valve assembly. The control valve is designed to accommodate minor plumbing misalignments. It is not designed to support the weight of the unit.
5. Please see page 3, item 3 for assembling and soldering of ttings.
6. Install an appropriate grounding strap across the inlet and outlet piping of the water conditioning system to
ensure that a proper ground is maintained.
7. Move the brine tank into place. Making sure that the oor is clean of any debris. Sharp objects such as rocks
can cause punctures to the brine tank over a period of time. This would not be covered under Marlo’s warranty.
(DO NOT ADD SALT AT THIS TIME).
8. Connect one end of the brine line (brine line is located inside the brine tank. Marlo units come with 5’ of brine
line) to the brine elbow of the brine tank and the other end to the brine elbow on the control valve. The brine
elbow on the control valve is black in color and located on the top of the control valve. The brine elbow swivels
to allow the brine tank to be placed in a convenient position.
9. The drain line connector is located on the top of the control valve and is black in color. The water softener comes
standard with 5/8 insert and nut if installer is using a poly tube. The drain elbow is threaded, so a ¾” drain line
may also be used. NOTE: If soldering the drain line use caution so as not to cause damage to the drain elbow.

Page 8
“GF” SERIES AUT OMA TIC W ATER CONDITIONERS
INSTALLATION
10. An overow tting is attached to the outside of the brine tank (overow elbow is white in color). Attach a 5/8
drain line (do NOT connect overow tubing with drain line tubing). The overow tting is installed in case the
unit would malfunction and water would continually run to the brine tank. The overow (if tubing is connected)
would allow the excess water to be run to the drain rather than overow onto the oor. Do NOT run overow
tubing above the overow elbow at any point.
C. Installation and Start Up
1. Make sure all connections have been made: Inlet, outlet, brine line installed and connected to the brine tank
and control valve, drain line installed, and over ow drain tubing connected and run to the drain. (DO NOT
CONNECT DRAIN LINE AND OVERFLOW TUBING)
2. If the unit is not in bypass please do so now. If using a bypass purchased with the unit the unit will be in the
bypass position when the two arrows on the handles of the bypass are pointing towards each other (see gure
2 page 12).
3. Turn on your main water supply. Locate a cold soft water tap and turn it on, allow the water to run until all excess air and foreign material is removed from the water.
4. Add seven (7) gallons of water to the brine tank.
5. Plug the water softener into the designated receptacle. Program the current time of day (see page 9 for instructions).
6. Press and hold the REGEN button (located in the upper right hand corner) until the unit starts a regeneration
(depending on how the unit is programmed the rst cycle may be back wash or brine ll). Once the piston
stops moving and the unit is counting down press the REGEN key again. This will advance the unit to the next
cycle. Repeat this process until you see the word RINSE in the upper left hand corner. Slowly open the inlet
side of the bypass (see page 13 gure 3). Let the water run to the drain until the water runs clear.
7. Place the bypass back into the bypass mode (see page 13 gure 2)
8. Press the REGEN button again to cycle the unit to the next cycle. Wait for the piston to stop moving and press
the REGEN button again. Repeat this until the unit is at the home screen. The home screen will be blue in
color.
9. Press and hold the REGEN button again until the unit starts a regeneration. Depending on how the unit it set
up you might have to wait for the piston to stop moving and press the REGEN button again repeating several
times till the word BACKWASH appears in the upper left hand corner. On most units BACKWASH should appear at the rst screen.
10. Slowly turn the handle of the incoming water (See page 13 gure 3) until the bypass valve is completely
opened. Once you have a solid ow of water to the drain, open the outlet side of the bypass (see page 13
gure 1) to duplicate the normal operation.
11. Press the REGEN button again to cycle the unit to the next cycle. Wait for the piston to stop moving and press
the REGEN button again. Repeat this until the unit is at the home screen. The home screen will be blue in
color.
12. Set the incoming hardness of the water, time of regeneration and calendar override. See page 8 Steps 1I
through 6I.
13. Add salt to brine tank.

D. Manual Regeneration
The user can initiate manual regeneration.
Pressing and holding the REGEN button for approximately 3 seconds will immediately start the regeneration. The
user cannot cancel this request.
NOTE: Program Timer “Lockout” Feature
The Program Timer is initially set to allow access to all Programming, Diagnostic and History screens. The Installer
can limit access to (lockout) most screens by activating the Lockout Feature.
Activating “Lockout” allows the user to view and change only Water Hardness, Days Override, Time of Regeneration and Time of day.
Activate “Lockout” Feature: Press DOWN then NEXT then UP then CLOCK in sequence. LOCK will briey appear in the display.
De-activate “Lockout” Feature: Press DOWN then NEXT then UP then CLOCK. UNLOCK will briey appear in
the display.
When in operation normal user displays are time of day, gallons remaining, days remaining before regeneration,
or current ow rate are shown. The user has the option to choose which screen is displayed by pressing the NEXT
button. When stepping through a procedure if no buttons are pressed within ve minutes the display returns to a
normal user display. Any changes made prior to the ve minute time out are incorporated. The one exception is
current ow rate display under the diagnostic procedure. The current ow rate display has a 30 minute time out
feature.

OPERATION
Control Valve Function and Cycles of Operation
This glass lled Noryl1 fully automatic control valve is designed as the primary control center to direct and regulate
all cycles of a water softener or lter. When the control valve is set up as a softener, the control valve can be set
to perform down ow or up ow regeneration with the proper piston. When the control valve is set up as a lter,
the control valve can be set to perform down ow regeneration or simply backwash. The control valve can be set
to regenerate on demand (consumption of a predetermined amount of water) and/or as a time clock (passage
of a particular number of days). The control valve can be set so that the softener can meet the Water Quality
Association (WQA) or NSF International efciency rating.
The control valve is compatible with a variety of regenerants and resin cleaners. The control valve is capable of
routing the ow of water in the necessary paths to regenerate or backwash water treatment systems. The injector
regulates the ow of brine or other regenerants. The control valve regulates the ow rates for backwashing,
rinsing and the replenishing of treated water into a regenerant tank, when applicable.
The control valve is designed to deliver high service (27 gpm @ 15 psig) and backwash (27 gpm @ 25 psig) ow
rates when the bypass has straight ttings and a 1.050” distributor. The control valve uses no traditional fasteners
(e.g. screws), instead clips, threaded caps, nuts and snap type latches are used. Caps and nuts only need to
be rmly hand tightened because radial seals are used. Tools required to service the valve include one small
blade screwdriver, pliers and a pair of hands. Disassembly for servicing takes much less time than comparable
products currently on the market. Control valve installation is made easy because the distributor tube can be cut
1/2” above to 1/2” below the top of the tank thread. The distributor tube is held in place by an
o-ring seal and the control valve also has a bayonet lock feature for upper distributor baskets.
The transformer power pack comes with a 15-foot power cord and is designed for use with the control valve. The
transformer power pack is for dry location use only. The control valve remembers all settings for up to 8 hours if
the power goes out and the battery is not depleted. After 8 hours, the only item that needs to be reset is the time
of day; other values are permanently stored in the nonvolitile memory. If a power loss lasts less than 8 hours and
the time ashes on and off, the time of day should be reset and the non rechargeable battery should be replaced.
The replacement battery is a commercially available 3 volt Lithium coin cell type 2032.
Table 3 shows the order of the cycles when the valve is set up as a softener. When the control valve is used as
a down ow softener, two backwashes always occur. When the control valve is used as an up ow softener, only
one backwash occurs after brining. The installer has the option of having the regenerant rell after the rinse cycle
or have the regenerant prell before regeneration. If the installer chooses to have the regenerant prell before
regeneration, the prell starts two hours before the regeneration time set. During the 2-hour period in which the
brine is being made, treated (softened) water is still available. For example: regeneration time = 2:00 A.M., prell
option selected, downow softener. Fill occurs at 12:00 A.M., start of backwash cycle occurs at 2:00 A.M.

OPERATION
NOTE: SALT LEVEL screen
only appears if programmed.
When the system is operating, several displays may be shown.
Pressing NEXT will alternate between the displays. One of the
displays is the current time of day. CAPACITY REMAINING
is the gallons that will be treated before the system goes through
a regeneration cycle. Pressing DOWN while in the Capacity
Remaining display will decrease the capacity remaining in
10 gallon increments and will also increase the volume used
impacting the recorded values in Diagnostics Steps 3D, 4D
and 5D and Valve History, Step 4VH. DAYS TO A REGEN
is the number of days left before the system goes through a
regeneration cycle. Pressing UP or DOWN while in this screen
will temporarily increase or decrease the displayed value by 1 day.
Another display shows the current treated water ow rate through
the system. Contact information will be displayed if it was edited.
For concerns with phone number or banner text displays, contact
OEM for instructions. The fth display will show either DP or
HOLD if the dP switch is closed. If the system has called for a
regeneration that will occur at the pre-set time of regeneration,
the words REGEN TODAY will alternate with the header on the
display. If a water meter is installed, GPM ashes (and alternates
with the ow rate) on the display when water is being treated (i.e.
water is owing through the system). If Salt Level Monitor has
been set to ON in Step 16S, the Salt Level screen will appear. To
adjust the salt level, press CLOCK, and use UP or DOWN to set
the current value. The salt level is adjustable from 0 to 500 lbs. in
10 lb. increments.
GPM and ow rate
will ash while water
is being treated.
REGEN PENDING will be displayed in Alternator Systems whenever a unit is waiting to
initiate the rst cycle step of regeneration.
STAND BY will be displayed in Alternator Systems when a valve is in Standby state.
DELAYED RINSE+FILL PENDING will be displayed whenever a zero-capacity tank has
transferred to an off-line state and is currently waiting to initiate the second portion of a
regeneration cycle. Viewed only when Delayed Rinse and Fill is set to ON.

Set Time of Day
The user can also set the time of day. Time of day should only need to be set if the battery has been depleted because of extended
power outages or when daylight saving time begins or ends. If an extended power outage occurs, the time of day will ash on and
off which indicates the time of day should be reset. The non rechargeable battery should also be replaced.
Regeneration Mode
Typically a system is set to regenerate at a time of low water usage. An example of a time with
low water usage is when a household is asleep. If there is a demand for water when the system is
regenerating, untreated water will be used.
When the system begins to regenerate, the display will change to 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.
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
be a period of heavy water usage because
of guests or a heavy laundry day.
To initiate a manual regeneration at the preset delayed regeneration time, when the regeneration time option is set to
“DELAYED REGEN” or “DELAY + IMMEDIATE”, press and release “REGEN”. The words “REGEN TODAY” will
periodically be shown on the display 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. Note: If the regeneration time option
is set to “IMMEDIATE” there is no set delayed regeneration time so “REGEN TODAY” will not activate if “REGEN” button
is pressed.
To initiate a manual regeneration immediately, press and hold the “REGEN” button for three seconds. The system will begin
to regenerate immediately. The request cannot be cancelled.
Note: For softeners, if brine tank does not contain salt, ll with salt and wait at least two hours before regenerating.

Power Loss
If the power goes out the system will keep time until the battery is depleted. If an extended power outage occurs, the time of day
will ash on and off which indicates the time of day should be reset and the non rechargeable battery replaced. The system will
remember the rest.
Error Message
If the word “ERROR” and a number are displayed contact the Installer for help. This indicates that the valve was not able to function
properly. If the number and banner text in the Contact Screens has been edited, the two displays below will alternate.

OPERATION
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 WS1 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
bypass 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 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.

Normal Operation:
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.
Figure 3
DIAGNOSTIC MODE
Supply
Water Exits
Diagnostic:
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.
Supply
Water Enters
Bypass:
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.
Figure 4
SHUT OFF MODE
No
Water Exits
Shut Off:
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).
