Introduction Operation
Step 1.
Service Cycle
In the service cycle, raw water enters the inlet port of the media tank. The oxidation process begins.
This air/water contact oxidizes the iron and hydrogen sulfide in the water. Oxidized iron particles
are trapped by the filter bed as the water passes through. Filtered water enters the lower distributor
and travels up the distributor tube to the outlet port on the filter valve.
Step 2.
Aeration Operation Air Recharge Cycle
When energized, the air pump sends air through the solenoid valve into one end of the shuttle valve.
Once air pressure in the shuttle valve is greater than the water supply pressure at the other end of the
shuttle valve, the piston shifts to the open position. In the open position, the bleed-off port discharges
excess water and old air to the drain port through a flow restrictor. Simultaneously, the air inlet port
opens to provide a direct connection between the air pump and the top of the media tank. The air
pump runs for a preset period of time recharging the head of air in the media tank.
Air Recharge Shut Off
The timer turns power off to the air pump and the solenoid valve at the end of the recharge cycle. The
solenoid valve then closes the port between the air pump and the shuttle valve. The port between the
shuttle valve and the atmosphere opens and releases air pressure. This allows water pressure to shift
the piston to the closed position. With the piston in the closed position, the air recharge inlet port is
closed and direct communication between the bleed off tube and the drain port is also closed.
Timer Operation
A timer controls the air recharge cycle and how frequently it occurs. The timer simultaneously
energizes the air pump and the solenoid valve. After a preset amount of time, the timer shuts off the
air pump and de-energizes the solenoid valve.
Solenoid Valve Operation
The solenoid valve is a three-way valve having ports that connect to the air pump, shuttle valve and
the atmosphere. In the service cycle, the solenoid valve is de-energized and closes the port to the
air pump, providing a positive shut-off to the pump. This prevents water from backing up into the air
pump and damaging the pump. In the air recharge cycle, the solenoid valve closes the port to the
atmosphere and opens the port from the air pump.
Shuttle Valve Operation
In the service position, water pressure holds the shuttle valve piston in the closed position, trapping the
airhead in the media tank and closes the air recharge inlet port and drain port. During air recharge
cycle, air pressure is greater than the water pressure and forces the shuttle valve piston in the open
piston. The shuttle valve has an internal pressure relief valve that will relieve pressure (greater than
100 psi) that may build up in the media tank. This precautionary function protects components from
failure due to excessive pressure.

Step 3.
Filter Tank Operation - Backwash Cycle
Reversing the flow of water through the filter bed and backwashing dirty water to the drain cleans
the filter bed. Raw water enters the filter control valve through the inlet port and is directed down the
distributor tube and out the lower distributor at the bottom of the tank, flowing upward through the
multimedia filter bed toward the top of the tank into the control valve. Water is then directed through a
specific flow restrictor and out the drain port to be discharged to drain.
Step 4.
Filter Tank Operation - Rinse Cycle
The rinse cycle packs the clean filter bed. Raw water enters the control valve through the inlet port
and is directed downward through the filter bed into the bottom distributor, up the distributor tube into
the control valve. Water is then directed through a specific flow restrictor and out the drain port to be
discharged to drain.
Operation Of Aeration Pump
The Sulfur-Cleer™ system introduces air into the media tank and bleeds off the old head of air
automatically. The exchange of the air into the media tank is controlled independently of the recharge
frequency of the filter media tank, allowing the air to be exchanged on a more frequent basis. During
an air exchange cycle, the air compressor pumps fresh air into the media tank and the air eliminator
solenoid exhausts the old air.
Iron and Trace Hydrogen Sulfide
When applying the filter on water sources with only iron present or with levels of hydrogen sulfide less
than 1 ppm, only backwashing will be needed to regenerate the filter. In some applications, odors
may develop over time and the media bed may need to be sanitized. In general, bleach will not be
required more than once per month and users generally find that it is needed no more than once every
four to six months, if at all.
Hydrogen Sulfide - Over 1 PPM
When applying the filter on water sources with hydrogen sulfide levels of 1 - 5 ppm, backwashing
every three days and eduction of diluted non-scented bleach on occasion may be needed.
Regeneration with bleach is only necessary when hydrogen sulfide is present in the product water.
Although the air compressor provides much of the action needed to reduce hydrogen sulfide, the
bleach will “super oxygenate” the Culligan CIM media to enhance effectiveness. Overdosing with
bleach will cause a faster breakdown of the media. Therefore, any chlorine dosing scheme involves a
compromise between media life and hydrogen sulfide reduction.

Introduction
(cont.)

The concentration limits listed below reflect the minimum or maximum individual limit that each
contaminant was tested for separately without any interference of other contaminants in the influent
water.
In reality, however, we know that these contaminants may be present in combination which may limit
the filter’s ability to remove these contaminants in higher concentrations. In some cases, individual
sellers of this equipment have had success removing higher concentrations of contaminants - iron, for
example - above the limitations we have listed. If you are considering the installation of this system
for the reduction/removal of iron, manganese and/or hydrogen sulfide beyond the printed operating
conditions below, we recommend that you consult the manufacturer for proper application. Installation
of this system under these circumstances may void part(s) and/or all of the system warranty.
General Instructions — Observe all state and plumbing codes, electrical codes and drain
restrictions. The system and installation must comply with all state and local laws and regulations. Most
codes require an anti-syphon device or airgap.
For installations in Massachusetts, the Commonwealth of Massachusetts Plumbing
Code 248 CMR shall be adhered to. Consult with your licensed plumber for
installation of this system. The use of saddle valves is not permitted.
Alkalinity — A minimum alkalinity of 100 ppm is required for efficient removal of iron and hydrogen
sulfide.
Hydrogen Sulfide — Often referred to as rotten egg odor, hydrogen sulfide will be reduced
significantly on water supplies containing less than 5 ppm as tested by Culligan. Consult the factory if
hydrogen sulfide concentrations are greater than 5 ppm.
Iron — This system is rated for a maximum of 10 ppm of ferrous (clear water) iron. Consult the
factory if iron bacteria is present.
Organic Matter (Tannins) — The presence of organic matter such as tannins will prevent the
oxidation process of converting the dissolved element, such as iron or manganese, to a non-soluble
precipitate or solid substance, allowing it to be filtered out. The Sulfur-Cleer™ is not designed to
remove organic bound iron.
pH — The pH level of the influent water must be 7.0 - 8.5.

Familiarization
Power Loss
The Circuit board is equipped with a Hi-Cap Capacitor and EEPROM memory chip. The capacitor is
capable of maintaining the time, for at least two days, in the event of a power outage. The EEPROM
ensures that the individual programming parameters of your filter are not lost.
If the power outage lasts long enough to drain the Hi-Cap Capacitor, the control will flash “12:00 PM”
when power is returned to the control. The unit will continue to keep time from the moment power is
restored, and will initiate a full regeneration at the preset regeneration time. The time of day will need
to be reset in order to return the regeneration to its preset time.
If you live in an area where power outages occur with a regular frequency, a battery backup option
is available for ensuring that the time of day is properly maintained. Contact your Culligan Dealer for
more information.
Regeneration
To initiate a regeneration at the preset time, press the “REGEN” button. The “REG” light will light. To
initiate an immediate regeneration, press and hold the “REGEN” button for at least five seconds. The
“REG” will light and blink. An immediate regeneration will also occur if a power outage has lasted
for more than four hours and the Immediate Regeneration option is chosen. Ask your Culligan Dealer
about this feature.
A regeneration at the Time of Regeneration will occur if so signaled by the Soft-Minder meter. The
“REG” enunciator on the display will also be lit.
Service
Culligan’s Sulfur-Cleer™ water filter is equipped with a self diagnostic program to insure optimal
operation of your water filter. Should service become necessary, a phone icon will appear in the
display. If this condition occurs, call your local Culligan Dealer for assistance. The phone icon and
error code will be the only items displayed when service is required on the control.

Modes of Operation
Manual Regeneration
Pressing and holding the regen button for 5 seconds will initiate an immediate regeneration. The
beeper is to give one beep at the start of manual regeneration (when the motor starts to turn). In delay
mode, pressing and releasing the regen button will light the regen icon for regeneration to occur at the
set delay time. Pressing and releasing the regen button again will turn off the regen icon.
Power Loss
The circuit board is equipped with a Hi-Cap Capacitor and EEPROM memory chip. The capacitor is
capable of maintaining the time, for at least one day, in the event of a power outage. The EEPROM
ensures that the individual programming parameters of your softener are not lost.
If the power outage lasts long
enough to drain the Hi-Cap
Capacitor, the control will flash
“12:00 PM” when power is
returned to the control. The
unit will continue to keep time
from the moment power is
restored, and will initiate a
full regeneration at the preset
regeneration time. The time
of day will need to be reset in
order to return the regeneration
to its preset time.
If you live in an area where
power outages occur with a
regular frequency, a battery
backup option is available for
ensuring that the time of day is
properly maintained. Contact
your Culligan Dealer for more
information.

Once either of the Information menus is entered the information shown for each display is outlined
below:
• Flow Rate (Meter mode only) - The display shall show the
current flow rate of the water passing through the control. The
display will first show “FLOW” for two seconds and then display
the current flow rate for 10 seconds. The meter factor must be set
properly for flow to be recorded accurately. This circuit board
has a default meter factor of 80 which is the proper setting for use
with Culligan standard 1” meter.
• Today’s Water Usage (Meter mode only) - This display
will show the accumulated flow of water for the current day. The
value should reset to zero daily at 12:00am. The display will
show “tU” with the gallon value (the x10 should appear when
necessary if the amount counts past 999 gallons; rollover at 10k
gallons).
• Average Daily Water Usage - This display will show a
running 7-day average of daily water usage. The display should
update daily at 12:00am. The display will show “AVG” with
the gallon value (the x10 should appear when necessary if the
amount counts past 999 gallons; rollover at 10k gallons).
• Number of Regenerations in Last 14 Days - This display
will show the number of regenerations that have occurred in
the last 14 days. The display will first show “14dAY” for two
seconds and then display the number of regenerations that have
occurred for 10 seconds. The days counter is to be updated at
the programmed time of regeneration for delayed regeneration
settings and at 12:00 AM (24:00) for immediate regeneration
settings. The counter is not to be updated during programming of
time of day if the days setting point is crossed.
• Maintenance Interval (Only available with dip #2
on) - This display indicates the number of days remaining
of the programmed maintenance interval. When this value
reaches zero, the “MAINT” alert will be activated. This setting
is resettable by holding the regen key for 10 seconds while at
this display, also it will clear the “MAINT” alert. The display will
show “MAINT” for 2 seconds followed by the number of days
remaining for 10 seconds.

When and
How to
Bypass
Your Water
Conditioner
13
Normally, all water except outside lines passes through the water conditioner. There are times when
the water conditioner should be bypassed, using the push-button Cul-Flo-Valv®Bypass, or a 3-way
bypass valve. You should bypass:
1. If lines to outside faucets do not bypass the water conditioner, and you do not want to waste soft
water on lawn sprinkling or other outside uses.
2. If you are going away on vacation and want to save salt by not having the unit recharge while
you’re away.
Bypass Valve
In the back of Culligan water conditioners is a Cul-Flo-Valv®Bypass. To bypass unit, simply turn the
blue knob clockwise. To return to soft water service, reverse the procedure - turn the blue knob counter-
clockwise.

Regeneration
with Bleach
When bleach is used to regenerate the Sulfur-Cleer™, Culligan strongly recommends the dealer set-up a
service contract with the customer to initiate the regeneration when required.
If a service contract is not practical, then Culligan recommends the dealer and the customer strictly
abide by the following procedure when regenerating with bleach:
• The dealer must instruct the customer on the handling of chlorine and review the DANGER
statements on the bleach bottle with the customer.
• The dealer must review the first aid instructions on the bleach bottle with the customer.
• The dealer must be present with the customer during the first regeneration.
• Protective eyewear and gloves are required.
See the Installation and Operation Manual or contact the Culligan Dealer for regeneration procedure
with bleach.

Caution! USE AND HANDLING OF HOUSEHOLD BLEACH
Bleach is a strong oxidizing agent. It can cause severe irritation or damage to eyes and
skin. Observe all precautions stated on the bleach container.
• Store the bleach in a cool dry place out of reach of children and pets.
• Do not store an unmarked container or a container with any markings which could
mislead someone as to its actual contents.
• Keep the bleach covered when not in use and tightly closed.

Things to
Check Before
You Call for
Service
If you unexpectedly experience problem water, make these simple checks before calling your Culligan
dealer. One of the following conditions may be the reason for your interruption of service.
Important
If any of the following conditions is found, the water filter should be manually recharged according to
instructions on page 5 after you have corrected the problem.
Power Supply
Check your power supply cord. Is it plugged fully into the electric outlet? Be certain that the outlet is
not controlled by a wall switch which has been turned off. Reset conditioner to proper time of day and
then plug in.
Blown Fuse
Check the house fuse or circuit breaker panel. Replace a blown-out fuse or reset an open circuit
breaker.
Power Failure
Any interruption in your power supply or time changes - such as daylight savings - will disrupt your
filter’s recharge schedule by causing the timer to run off-schedule. Reset timer to proper time of day.
Bypass Valves
Check to see if they are in the proper position. Cul-Flo-Valv®Bypass, if used, should be in the
“Service” position. If hand valves are used, see that inlet and outlet valve are opened and that the
bypass valve is closed.
No Water
If you aren’t getting any water flow at all, make sure your water supply is working. Open a tap ahead
of the filter (outside tap) to see if you have any water pressure. If you have water pressure, check the
bypass valve. If it is in the Service position, put it into the bypass and call your Culligan dealer for
service.
Increased Usage
Guests, family additions, new water-using appliances, etc., all will result in more water usage and will
require more capacity from your filter. You can reprogram your recharging schedule by following the
directions on pages 7 and 8. Call your Culligan dealer for advice and save a service call.

Preventative
Maintenance
The Culligan Sulfur-Cleer™water filter has been designed to provide a good, consistent service life.
Because of the nature of problem water, we recommend that the local Culligan dealer provide regular
maintenance/service contracts for the proper operation of your systems. The water filter service
begins with a multi point inspection of your water filter system in an effort to uncover any and all
problems that may exist. Listed below is a recommended list of maintenance items to be inspected at
a minimum of once a year (or more frequently depending on the raw water quality).
