2 Culligan® CSM Series Filters 2 Cat. No. 01016449
Performance Specifications
When selecting and sizing a CSM filter for a specific application, the backwash flow rate should be taken into account
prior to determining if the service flow rate is adequate. This is the most important function in the proper operation of a
filter. Periodically, the accumulated impurities (iron, sediment, etc.) must be removed (backwashed) from the filter. Back-
wash flow rates are always much higher than service flow rates and therefore limit the size of filter that can be installed.
As a general rule in sizing filters, select the largest filter that can be backwashed with the flow rate available at the point
of filter installation. Then note the service flow rate for the filter selected. If it is not adequate for the flow to be treated, a
twin or triple filter installed in parallel is required. A parallel installation will increase the service flow and yet permit each
filter to be backwashed separately with the existing water supply.
Superior water quality is recommended for most filtering applications under all operating conditions. Operating at these
service flow rates allows for the best quality of water, maximum time on line between backwashing, lowest pressure loss
and recommended is for influent suspended solids loads up to and greater than 300 ppm.
High water quality is recommended for many filtering applications. Operating at these service flow rates allows for very
good quality water, moderate time on line between backwashing, increased pressure loss and is recommended for influ-
ent suspended solids loads less than 300 ppm.
Utility water quality is operating at the peak design service flow rates of the filter system and operating at higher flow rates
are not recommended. Operating at these service flow rates allows for satisfactory quality water, shorter time on line
between backwashing, higher pressure loss and is recommended for influent suspended solids loads less than 150 ppm.
In order to function properly, some operational parameters must be followed. They include:
• An operating water pressure between 30 and 100 psi. If water pressure is greater, a pressure regulating valve
should be installed ahead of the system. If water pressure is lower, additional equipment will be required to main-
tain a 30 psi minimum operating pressure.
• Operating temperature between 40° and 120°F or 4.4° to 48° C.
Multi-layered filters are capable of 10 micron effluent water quality or better, whereas, all other filter types are capable of
40 micron effluent water quality or better.
All pressure drop figures are based on new filter media and a water temperature of 60ºF.
NOTE The tanks are available with Non-A.S.M.E. code steel tanks (NC) or with A.S.M.E. code steel tanks (CD).

Basic Principles
Activated Carbon Filter
“Carbocleer” filters reduce unpleasant taste and odors from the water supply. In normal operation, the water passes
through the multi-port valve into the top of the media tank. As it flows down through the mineral bed, sediment in the wa-
ter is filtered out and objectionable dissolved gases are absorbed into the mineral. The clear water that leaves the bottom
of the media tank and goes into the service lines is free from many disagreeable tastes and odors.
To keep the filter operating properly, it is necessary to periodically remove the accumulated sediment from the mineral
bed. This is done by a three step cleaning process:
Backwash
The direction of flow through the tank is reversed and the mineral bed is “backwashed”. This action expands and agitates
the bed, releasing the sediment which is then carried up and out to the drain.
Settle
The media tank is allowed to set idle to allow the Activated Carbon to settle. Water flow to drain will be present during the
duration of this step.
Fast Rinse
A fast down flow “flush” repacks the mineral bed and washes out traces of sediment not removed by backwash.
Generally, backwashing once a week is adequate, however, more frequent cleaning is recommended for waters with high
turbidity. Filters operated semi-automatically or automatically should be backwashed when the pressure drop across the
bed is 8 to 10 psi higher than a normal clean filter bed.
Depth Filter
Depth filters filter both heavy sediment and suspended matter from the water supply. In normal operation, the water
passes through the multi-port valve and into the top of the media tank. As the water flows down through the mineral bed,
sediment in the water is filtered out, The clear water that leaves the bottom of the media tank and goes through the ser-
vice lines is free from most sediment and suspended matter.
To keep the filter operating properly, it is necessary to periodically remove the accumulated sediment from the mineral
bed. This is done by a three step cleaning process:
Backwash
The direction of flow through the bed is reversed and the mineral bed is “backwashed”. This action expands and agitates
the bed, releasing the sediment which is then carried up and out to the drain.
Settle
The tank is allowed to set idle to allow the different types of media to restratify and settle. Water flow to drain will be pres-
ent during the duration of this step.
Fast Rinse
A fast down flow “flush” repacks the mineral bed and the filter is again ready for service.
It is recommended that this cleaning process take place at least once a week. On units with pressure gauges, the differ-
ential pressure across the filter can be monitored. A depth filter should be cleaned when the differential pressure across
the filter increases by 8-10 psi over the pressure differential across a clean filter bed.

Controller Features 7
Cat. No. 01016449
Controller Features
The Culligan MVP control’s (Figure 5) primary function is to initiate and
control the regeneration process via methods that are most convenient and
cost effective for the customer while offering many operation features and
benefits.
Features
Power Source
Electrical power required for the control is 24-Volt 50/60 Hz AC current. A
plug-in transformer (120v/24v) is provided
Battery Backup
Battery backup is available as an optional field add-on. The battery backup
will maintain the time of day for a minimum of 4 weeks using a 3.6V 1/2AA-
lithium type battery as supplied by Culligan.
EEPROM
Saves programmed and statistical functions.
AC Outputs
Four AC outputs are found within the controller for the following purposes:
• Motor control
• Blocking Valve (blocks the flow of water to service)
• Two programmable outputs for various optional accessories
One-Touch Program Update
Multiple controls can have their programs updated simply through the touch of a button on the primary or “Master” control
eliminating the need to the programming process for each subsequent control in a system.
Lock/Unlock
Allows the control to be easily locked out from inadvertent program changes or abuse. This feature can be disabled if
desired.
Time of Day
Displays current time in either 12 hour (AM/PM) or 24 hour format.
Current Day of Week Regeneration
This feature is available for single, time clock operated systems.
Regeneration Interval
Provides an ability to initiate a time clock operated system on a number of days (range from 1 to 99 days), hours (range 1
to 24 hours), or a specific day of the week (single, time clock systems).
Progressive Flow Trip Point
Use of this patented feature allows multiple tank systems operating with water meters to be brought on-line or off-line as
facility flow demands increase or decrease.
Regeneration Start Delay
Allows a user determined number of hours (up to 9) to be input into the control for the purpose of increasing the amount
of time between multiple regeneration initiations.
Figure 5.

Program Beeper
Emits an audible beep when key pads are depressed to help identify valid (short beep) or invalid (3 short beeps) key pad
touches. Can be enabled or disabled as desired.
Screen Blanking
The screen can be programmed to go blank once programming is complete (After 5 minutes of no keypad activity).
Flow Meter/Sensor Input
Various types of Hall effect flow sensors can be used to measure the amount of treated water provided and initiate a
regeneration sequence.
Auxiliary Input
The auxiliary input is capable of accepting a remote signal from a dry contact device such as an operator push-button for
the purpose of initiating the regeneration sequence.
Home and Position Switch Inputs
The home and position switch inputs work to automatically detect the cycle position of the valve and properly configure
the circuit board for operation with either a four or five-cycle valve. The inputs also assist the operator to troubleshoot
many types of service problems.
Multiple Unit Communication Input/Output (RS485)
The communication input/output feature routinely recognizes when another controller within a multiple controller system is
in a regeneration sequence, prohibiting the chance of multiple units regenerating simultaneously. Additionally, the Com-
munication input/output feature provides the means to operate the controller in the Progressive Flow mode.

Operation 9
Cat. No. 01016449
Operation
Modes of Operation
Time Clock
The controller will initiate a regeneration based upon a time schedule of either hours (between 1 to 24 hours), intervals of
days (i.e., every 3 days) or on a specific day of week schedule (i.e., Mondays, Wednesdays and Saturdays).
Differential Pressure
When combined with an optional differential pressure device, the Culligan MVP controller has the ability to initiate a back-
washing sequence when the pressure differential across the media bed reaches a preset amount (usually 8 to 10 psi).
Progressive Flow
Used with up to six and as few as two mineral tanks in a system, the Progressive Flow mode allows more than one tank
in a system to either be on-line or off-line depending upon the downstream flow demand. If flow demand is greater than
the flow capability of the tank on-line, another tank can be brought on-line to help satisfy the excess demand. Once the
demand has decreased, the second tank is returned to a standby mode and the system reverts to just one tank on-line
providing treated water.
The progressive flow mode of operation relies on a user programmable set point or Trip Point. The Trip Point is a unit of
flow (gallons or liters) on a per minute basis. Once attained the trip point will cause the second unit (in multiple resin tank
system) to come on-line. Each additional resin tank in the system will subsequently be brought on-line as multiples of the
trip point are attained. (Example: a 3 tank system with a trip point of 50 gpm will bring have two tanks on-line once the
facility flow demands is equal to or greater than the 50 gpm trip point. Should the flow demand reach 100 gpm or more,
the third tank shall be brought on-line.
Additional tanks shall be returned to stand-by once the facility flow demand is <95% of the trip point for two tank systems,
<95% of 2X the trip point for triplex systems and <95% of 3X the trip point for quad systems, and remains there for 60
seconds.
Utilizing the progressive flow feature may allow the owner to use smaller water softening models, resulting in the potential
for reduced capital and operation costs.
The Progressive Flow setting may be used in combination with differential pressure device.

Make certain to follow each step carefully to insure that the filter runs trouble free. Also, be sure all plumbing practices
conform to local plumbing codes.
Locate Filter
1. Check inside the tank to make sure that all of the plastic distributors and laterals (Figure 9) are tight.
CAUTION! Do Not Proceed if any distributors or laterals are broken.
Consult Culligan for assistance. If any are loose, hand
tighten only. Do not use a wrench.
2. If the tank drain valve option kit was purchased, install it at this time.
3. Select a position near a floor drain that has adequate carrying capacity to han-
dle the filter’s backwash flow rate. Refer to section, “Performance Specifications”
on page 2for specific backwash flow rate.
4. Erect the resin tank on a level firm foundation, preferably concrete. The valve
and piping normally face the front for easy access.
5. Level the system.
Install Piping
1. Depending on the type of filter system (i.e. single, twin, etc.) and installation parameters, required pipe lengths
and piping accessories will vary. Sample layout drawings (Figure 6, Figure 7 and Figure 8 on page 10) are
provided to aid the installation. If the layout drawings are not sufficient for your application, consult the equip-
ment provider for specific installation guidelines.
The use of unions on the inlet and outlet isolation valves is recommended to
facilitate service of the softener unit. It is recommended that a full flow by-pass
line be provided.
NOTE All pipe fittings and assemblies should follow good plumbing practices
for installation.
They are:
• Check the threads and make certain that they are clean and free of foreign
matter.
• Fittings must be free of cracks or chips.
• Prepare threads with either a pipe dope sealant or Teflon tape.
• Make certain that the fittings are not cross threaded during the assembly
process.
• Do not over-tighten fitting or threaded pipe being inserted into a cast or
forged part.
CAUTION! Never connect two dissimilar metals (such as copper pipe and aluminum valves) togeth-
er when plumbing the vale to the piping system. The use of unions (dielectric unions
if piping to cast iron valves) on copper or galvanized steel pipe followed by schedule
80PVC or CPVC short nipples to attach the piping to the control valve is strongly recom-
mended to reduce the potential of corrosion by galvanic reaction.
2. Pipe a drain line from the backwash flow control assembly (left side of the Brunermatic valve) to the drain. Use
a minimum of elbows and increase or decrease the pipe size in order to make a connection to the backwash
flow control assembly. (see Figure 10) DO NOT install a valve in this line or use pipe smaller than listed in the

DO NOT make a direct connection to the drain. Provide an air gap of at least four times the diameter of the drain
pipe or conform to local sanitation codes and to permit the observation of the drain flow.
Installation of the Flow Measuring Device (Option)
Figure 11.
NOTE *interconnecting piping, bypass valve and isolation valves are not supplied.
NOTE Time or initiated regenerated systems do not necessarily require the use of a flow-measuring device.
Therefore your system may not utilize this portion of the manual.

Installation 13
Cat. No. 01016449
Two popular types of flow measuring devices can be used with the controller; paddlewheel flow sensors or the Culligan
in-line turbine meter. Please refer to the following chart for the number of meters required for your system configuration.
Table 4.
System Configuration Paddlewheel Flow Sensor Turbine Meter
Single 1 1
Duplex Parallel/Progressive Flow 2 2
Duplex Alternating 1 1
Triplex Parallel/Progressive Flow 3 3
To properly measure flow accurately, the paddlewheel flow sensor(s) must be installed with a certain amount of straight
pipe both before and after the paddlewheel flow sensor. The proper installation for these types of systems is shown on
below and page 14. Turbine meters do not have the same installation requirements and therefore may be positioned
immediately following the Brunermatic valve if the system is a single or parallel configuration or at any point in the com-
mon outlet header for alternating configurations.
Location of the Paddlewheel Flow Sensor Package
The flow sensor is to be mounted on the outlet piping of each
filter for single and duplex and triplex parallel systems and in the
common outlet piping of duplex alternating systems.
The piping that the flow sensor is being connected to should
be the same diameter as the mounting fitting. The flow sensor
must also be located in a free-flowing straight run of pipe. This
straight run includes the upstream piping and downstream pip-
ing of the flow sensor.
The proper length of upstream and downstream straight piping
is a minimum of 10 pipe diameters of free-flowing straight pipe
upstream of the flow sensor and 5 pipe diameters of free-flowing
straight pipe downstream.
EXAMPLE: A flow sensor that is installed on a length of 2” diam-
eter straight pipe (see Figure 13).
Major obstructions will require considerably longer straight runs
of upstream piping, due to the turbulence created by their pres-
ence.
EXAMPLE: A flow sensor on a length of 2” diameter pipe that
has a 90° elbow upstream from the desired location (see Figure 14).
The examples below are intended as guide lines for the proper length of straight pipe required both upstream and down-
stream of the flow sensor installation point.
These recommendations are minimum requirements (see Figure 12).

Position of the Flow Sensor Package
The flow sensor position is also important to the accuracy of the output signal. When
installing the flow sensor in a horizontal pipe, the optimum position of the flow sensor
in the pipe is at 0 or 180 degrees, assuming the pipe is always full of liquid and con-
tains no suspended solids. Air pockets or sediment in the pipe will disturb the rotation
of the flow sensor, causing inaccuracy in the output signal.
Because of certain installation requirements due to space restrictions, it may be nec-
essary to tilt the flow sensor slightly, (max. 45° angle). Excessive angles will cause
bearing drag on the flow sensor rotor at lower flow rates (see Figure 15).
On a vertical pipe run, it is preferable to locate the flow sensor where the flow is
upward. But, if downward flow is necessary, the system must be designed to prevent
air/water vapor pockets from developing in the pipe which will affect the performance of the flow sensor.
The maximum distance that the flow sensor can be located from the MVP controller is 500’. Paddlewheel type flow sen-
sors should be supported in the piping as required by local plumbing codes; typically 18” before and after each joint (in a
horizontal run of pipe).
Signet Flow Sensor Installation
NOTE Signet flow sensors must be installed as indicated. Failure to follow these instructions may result in
improper operation. Please refer to any supplemental instructions accompanying the flow sensor for
additional information.
1. Once you have located the flow sensor package and confirmed it is the correct size and material type for the
equipment at the site, proceed with installing the flow sensor mounting package.
2. You should follow good plumbing practices for all the installations. They are:
• Check the threads and make certain that they are clean and free of foreign matter.
• Fittings must be free of cracks and chips.
• Prepare threads with either a pipe sealant or Teflon tape.
• Make certain that the fittings are not cross threaded during the assembly process.
• Do not over-tighten the fittings or the threaded pipe that is being threaded into a casting or forging.
• Follow proper soldering processes as outlined in the plumbing code.
3. For each of the different types of installations, certain requirements must be followed to assure a proper installa-
tion.
a. Copper sweat tee - for use on copper tubing sizes. 1” 1-1/4”, 1-1/2”
and 2”. With the exception of the 1” copper sweat tee, all of the cop-
per tees include a plastic insert which the flow sensor will attach to.
This insert should be removed in order to properly solder the tee into
the correct position. A tag is attached to the fitting to indicate the prop-
er “H” dimension of the plastic insert when reassembling. This dimen-
sion is critical to the proper calibration of the flow sensor. Note the
location of the notch to the pipe (see Figure 16).
b. Threaded galvanized tee - for use on galvanized/iron pipe sizes 1”, 1-1/4”,
1-1/2” and 2”. All tees are threaded with NPT threads and have a plastic
insert to attach flow sensor. This insert is factory installed and should not
be removed. It is necessary for determining the proper location for the flow
sensor wheel when inserted into the fitting. Again this insert should not be
removed from the tee assembly (see Figure 17).

c. Copper brazolet - for use on copper pipe sizes 2-1/2” and 3”. The copper brazolet
should be installed by a certified welder. A hole will need to be drilled in the pipe at
the desired location as described in this section. The hole size should be 1-7/16” and
must be completely deburred and free of any projections. Prior to welding the brazo-
let, the plastic insert must be removed. A special tool is provided with each brazolet
assembly for the removal and the replacement of the plastic insert. When the plastic
insert is replaced (after the welding is complete), Teflon tape should be used on the
threads. There is a special card that is attached to the insert, this card indicates the
proper “H” dimension for the insert depth when you reassemble the insert back into
the brazolet. This dimension is critical to the proper calibration of the flow sensor.
Note the location of the notch to the pipe (see Figure 18).
d. Iron saddle - for use on steel pipe 2”, 2-1/2” and 3”. A 1-7/16” hole will
need to be drilled in the pipe at the desired location as described in this
section. The assembly comes complete with a plastic insert which is fac-
tory installed and should not be removed. The assembly also comes with
a rubber washer which must be installed between the clamp and pipe.
Coat the rubber washer with a silicon lubricant and place it on the inside
of the saddle and form it around the raised groove. With the flat side of
the rubber washer facing the pipe surface, insert the plastic insert and
saddle to the drilled hole. Using the saddle clamps, tighten the saddle
into place.
e. PVC socket weld tee - for use on sizes 1”, 1-1/4”, 1-1/2”, 2”, 2-1/2”, 3”
and 4” schedule 80 PVC pipe. All tees are socket welded with a NPT
threaded port containing a plastic insert to attach the flow sensor. This insert is factory installed and
should not be removed. It is necessary in determining the proper location for the flow sensor wheel
when inserted into the fitting. Again, this insert should not be removed from the tee assembly. Once
the flow sensor installation is completed, locate the warning decal attached to the flow sensor. Apply
the decal to a visible location near the flow sensor in the event service is required.
CAUTION! Be certain there is no pressure in pipe BEFORE removing or installing flow sensor.
Turbine Meter Installation
Turbine meters are less sensitive to position. They can be mounted horizontally or vertically but straight runs before and
after the meter are best for accuracy. If mounted vertically, the water flow must be upward. Turbine meters however must
be supported as required by local plumbing codes; typically 18” before and after each joint (in a horizontal run of pipe).

2. Make sure all manual valves are closed. To prevent damage to the distribu-
tion system, add approximately 2 feet of water to the media tank with a hose
(Figure 21). It is not recommended that the media tank be entered to receive
and load the gravel. With water in the media tank, carefully pour the gravel
slowly into the media tank, leveling as loading progresses. On media tanks
with only a handhole in the top, it is recommended that a funnel be used to
load the gravel into the media tank to help prevent spillage. When properly
loaded, the gravel should cover the distributor system in the bottom of the
tank. If it does not, contact your Culligan dealer before proceeding to Step 3.
CAUTION! Should it be necessary to enter the media tank, it is
recommended that a respirator be worn by any person
entering the tank to load gravel. Wet the bags of gravel
to reduce the amount of dust caused by the loading
procedure.
