1. PURPOSE
1.1. Overview
Ecosoft media systems are automatic water treatment appliances using bed ltration to
remove impurities. Ecosoft lters consist of the following main parts:
• pressure vessel made of berglass reinforced plastic
• automatic control valve mounted on the pressure vessel
• riser pipe, top and bottom distributors
• lter media
• (FK and FU systems only) brine tank with brine system
Ecosoft lters are used for treatment of household water, steam boiler and heating circuit
feed water, and other commercial and industrial water treatment processes. Di󰀨erent series
of Ecosoft lters are intended for removal of di󰀨erent types of impurities.
Pressure vessel size determines the quantity of lter media, ow capacity, and volume
capacity of the lter. When water passes through the lter, the lter bed accumulates
impurities that it works to remove. After using up the volume capacity of water, the material’s
holding capacity or exchange capacity becomes exhausted and the lter stops removing
more impurities (or the pressure drop builds up to critical value). At this point, the lter must
be rinsed or brine regenerated to restore its capacity. Volume capacity depends on the
quantity of lter media and composition of raw water.
When exhausted, non brine regenerated lters are backwashed and then forward rinsed
to release the accumulated impurities. Brine regenerated lters undergo backwash, then
rinse with brine from the brine tank to release hardness ions from ion exchange sites, then
forward rinse and brine tank ll.
Ecosoft lters use the following naming conventions:
FU
Type of system: FU, FK, FP, FPA or FPC
(described in the following section)

Pressure tank size: ‘12’ inch diameter, ‘52’ inch tank height
(rst two digits indicate the diameter, second two digits indicate the height)
CE
Control valve type: CE, CI, CT or DV
(described in the following sections)

1.2. Ecosoft FK advanced water softeners with Ecomix®
Well water often contains calcium, magnesium, iron, manganese, ammonia and natural
organic matter that would normally require multi-step water treatment to bring down all
the constituents to permitted concentrations. Ecosoft developed a proprietary solution for
removing all these impurities in one step and a single lter. Ecomix® advanced softening
media e󰀨ectively treats problem water even when complicated with non-neutral pH, high
TDS, and other noxious impurities.
Regeneration requires sodium chloride brine and exactly same equipment as in a regular
softener. Ecomix® is a complex media with ion exchange and adsorptive components
that function in synergy. After loading and backwashing, Ecomix bed straties in the right
succession of layers ready to operate.
1.3. Ecosoft FU ion exchange softeners resin with Dowex® resin
Water hardness accounts for the largest costs among all water quality issues incurred by
households, business, and public sector. Some of the symptoms of excessive water hardness
are limescale deposition inside water pipes and appliances, high detergent demand, poor
soap lathering, compromised plumbing xture appearance, overuse of electric power by
water heating appliances, poor skin and hair condition.
Water hardness arises chiey from calcium and magnesium dissolved in water. Ion exchange
softening is one of the simplest ways to reduce water hardness. Ion exchange resins work
by attracting and retaining ions of hardness metals in the polymer structure. For balance,
they release equivalent quantity of sodium ions.
When ion exchange capacity of the resin becomes depleted, the resin must be regenerated
to restore the capacity. During regeneration, tablesalt brine seeps slowly through the bed,
allowing sodium ions to displace and ush out ions of hardness.
Ecosoft water softeners use Dowex® ion exchange resin.
1.4. Multiple unit systems
In large and/or critical applications such as boiler feed water treatment, public water
services, manufacturing etc, softening units are usually required to operate uninterruptedly
without regeneration stops. In these cases, Ecosoft multiple unit systems are used.
Duplex systems comprise two softeners operating in parallel, locked out from simultaneous
regeneration and equipped with auxiliary motorized No Hard Water Bypass valves to

5
INSTRUCTION MANUAL ECOSOFT®MEDIA SYSTEMS
prevent hard water bypass during regeneration. Duplex systems can only be assembled
with CI and CE control valves. In a Duplex system, only one softener can regenerate at
any time. The other will remain online at least until the regenerating softener goes back in
service. When no softener is regenerating, both softeners will be in service providing two
times the ow rate.
Twin systems comprise two softeners with a single Twin type control valve, or alternatively,
two regular control valves and a Motorized Alternating Valve. In Twin systems, only one
softener is in service at any time, the other is regenerating or in standby. Twin systems are
assembled with a single brine tank for both softeners.
Triplex and larger multiple unit systems are used to provide uninterruptible water supply
when widely variable water demand is allowed for. Triplex systems are less water intensive
and can be programmed to di󰀨erent modes of unit activation. E.g., more softeners can be
put to service when water demand increases and vice versa. Regeneration will happen
during set time of the day. Triplex systems comprise three separate softeners equipped
with auxiliary motorized No Hard Water Bypass valves and a Clack multisystem controller.
Twin systems comprise two softeners with a single Twin type control valve, or alternatively,
two regular control valves and a Motorized Alternating Valve. In Twin systems, only one
softener is in service at any time, the other is regenerating or in standby. Twin systems are
assembled with a single brine tank for both softeners.
In the same way, larger multisystems with up to 6 softeners can be built using Clack
multisystem controller.
1.5. Ecosoft FPA granular activated carbon lters
Ecosoft FPA systems come with Filtrasorb® macroporous granular activated carbon.
Filtrasorb has high capacity and good hydraulic properties. Ecosoft FPA are timer-
regenerated backwash-only lters.
Filtrasorb® is used for removing chlorine and chlorine compounds, natural organic matter,
petroleum products, pesticides, and other pollutants. It also removes objectionable color,
tastes, and odors.
1.6. Ecosoft FPC catalytic carbon lters
Centaur® is a granular activated carbon with catalytic properties used for improving color,
taste, and odor of well water. Centaur® e󰀩ciency relies on its capacity to catalyze oxidation

INSTRUCTION MANUAL ECOSOFT®MEDIA SYSTEMS
6
of hydrogen sulde and adsorb oxidation products. It also removes small quantities of iron
and organic impurities.
In order to remove hydrogen sulde and iron, Centaur requires that enough dissolved
oxygen be present in water and a pH 7 or above. In some cases, raw water may need
corrective treatment to meet above requirement. It is possible to substitute oxygen with
injected oxidizers such as sodium hypochlorite, if necessary.
Ecosoft FPC are timer-regenerated backwash-only lters.
1.7. Ecosoft FP particle lters
Filter Ag® is a granular media used for reduction of suspended solids by removing particulate
matter. The media consists of irregularly shaped grains that trap and hold particles by
straining and adhesion. Common applications of Ecosoft FP systems include reducing
water turbidity, removal of oxidized iron oc in deironing systems, removal of sand, silt and
other. Ecosoft FP are timer-regenerated backwash-only lters.

Fiberglass reinforced plastic tank is the cylinder shaped plastic vessel with the lter
media. Control valve is mounted on the threaded top opening. Riser pipe runs down to
the bottom of the tank inside the pressure vessel, transporting water out of the lter during
service and into the lter during backwash. Bottom distributor is attached to its end to spread
ow of water uniformly and screen against ne particles.
Brine regenerable systems (FU and FK) include a brine tank – a plastic container with salt
pellets where the brine is stored then drawn from during regeneration.
Control valve.
CE, CI, and CT type control valves use a plunger piston mechanism to route inuent water
accordingly to the current cycle of operation. DV valves use a rotary disk mechanism.
CE, CI and DV control valves for softening systems (FU and FK series) have 5 cycles;
non-brine regenerable lters have 3 cycle CT control valves. The cycles are as follows:
1. in service mode, inlet water is sent through the lter bed to the puried water outlet;
2. during backwash, the control valve sends inlet water across the lter bed in the upow
direction to u󰀨 it up and release trapped impurities to drain outlet;
3. during fast rinse, inlet water is sent through lter bed downow and then to drain outlet;
4. (CE, CI, and DV only) during brine regeneration, inlet water is sent through brine injection
system to suction brine from brine tank and slowly displace it across lter bed to drain outlet;
5. (CE, CI, and DV only) during brine tank rell, inlet water is sent through the lter bed,
softened e󰀪uent rells the brine tank.

INSTRUCTION MANUAL ECOSOFT®MEDIA SYSTEMS
Filter media removes impurities from water. Rate of removal depends on the ow rate of
water going through the bed of media. E󰀩cient purication requires that the ow rate is
within specied range (not too high or too low). Recommended range of ow rates per each
type of lter is listed in specications in the end of this manual.
3. INSTALLATION
• Installation area must meet all relevant building code. Water and power supply, and
ambient conditions must meet Specication requirements of this manual.
• Observe all local plumbing and electrical code when connecting system to utilities
• Install check valve when connecting the lter to water mains. Install second check valve
after the system to prevent back ow.
• Particles such as sand, scale or rust can damage the control valve. Install a point-of-
entry sediment lter.
• Equip the system with sampling taps and pressure gauges as shown on drawings. It will
help in case any maintenance or troubleshooting is necessary.
• Install a vacuum relief valve as shown if there is a booster pump downstream of Ecosoft
lters. The FRP tanks may implode if subjected to negative pressure.
• If your system does not include bypass valve assembly, run a bypass pipeline along the
entire system. This may be necessary for diagnostics and maintenance.

3.1. Procedure for installing an FU, FK, FPA, FPC, or FP system
1. Install FRP tank on rm level surface capable of supporting its weight. Put riser pipe with
bottom distributor down in the pressure tank. Ensure that top end of riser pipe is level with
the top opening of FRP tank (within ±5 mm). It is advisable to ll the tank with water to about
⅓ its height if installing an FP, FPA or FPC system.
2. Put a plug or cap on the top end of the riser pipe to prevent getting any media inside
the pipe. Pour the media in the tank using the funnel. When loading the tank, keep riser
pipe vertical. If the pipe tilts, restore it to straight vertical direction. When nished, rinse the
thread of tank opening with water to remove any grains of media stuck in the groove.
3. Lock the top distributor in circular slot at the bottom of the control valve’s shank. Mate
the top distributor with top end of riser pipe, then screw control valve in the tank opening.
4. Connect drain pipe to the male threaded drain outlet of the control valve. Run the drain
pipe to oor drain or gravity drain pipe socket. Secure the drain pipe end above the receiving
xture with at least 1″ air gap.
5. If installing an FU or FK system, place the brine tank next to the FRP tank. Install exible
tube in the control valve’s brine inlet and run it to the brine tank. Remove tank lid and brine
well cap, pull the end of the tube inside and connect it to the brine valve, then re-assemble
in reverse order. Fill the brine tank with salt pellets at least half full.
6. Mount the pipe thread elbow adapters to the control valve’s In and Out ports and tighten
the coupling nuts. Do not put any mechanical load on ttings or use them to support pipes.
Connect the system to water supply and downstream pipework without turning on the water
supply. Do not confuse In and Out ports. They are embossed with direction arrows.
7. Remove the front panel by pulling the locking tabs on the left and right side. Run the
power cord through the cord guide in the control valve’s backplate and connect it to 12 VAC
socket on the circuit board. Plug the power supply in the mains to power up the system.
8. Start manual regeneration of the system. Scroll regeneration to backwash if it isn’t the
1st step of the sequence. When the control valve starts the backwash, turn on mains water
supply slightly at rst. Air will be displaced from the system via drain line while the pressure
tank is being lled with water. When the tank is full, water will start owing down the drain
line. At this point, fully open mains water supply. Carefully inspect the system for leaks.
Let the system complete regeneration, then perform one more manual regeneration.

3.2. Procedure for installing an FU Cabinet or FK Cabinet system
If your cabinet was delivered pre-loaded with resin, place the cabinet in the installation spot,
ll salt compartment with salt pellets, and then only carry out steps 5…8 of the procedure,
skipping steps 1…4. If the resin was shipped in bag, then carry out all of the following steps.
1. Disconnect the exible tube from brine inlet of the control valve. Unmount the valve by
screwing it counterclockwise.
2. Put a plug or cap on the top end of the riser pipe to prevent getting any media inside
the pipe. Pour the media in the tank using the funnel. When loading the tank, keep riser
pipe vertical. If the pipe tilts, restore it to straight vertical direction. When nished, rinse the
thread of tank opening with water to remove any beads of media stuck in the groove.
3. Mate the top distributor with the top end of riser pipe, then screw control valve in the tank
opening. Connect the free end of brine tube back to the brine inlet of the control valve.
4. Place the cabinet in the installation spot. Open top lid and ll the salt compartment with
softener salt pellets at least half full.
5. Connect drain pipe to the male threaded drain outlet of the control valve. Run the drain
pipe to oor drain or gravity drain pipe socket. Secure the drain pipe end above the receiving
xture with at least 1″ air gap.
6. Mount the pipe thread elbow adapters to the control valve’s In and Out ports and tighten
the coupling nuts. Do not put any mechanical load on ttings or use them to support pipes.
Connect the system to water supply and downstream pipework without turning on the water
supply. Do not confuse In and Out ports. They are embossed with direction arrows.
7. Remove the front panel by pulling the locking tabs on the left and right side. Run the
power cord through the cord guide in the control valve’s backplate and connect it to 12 VAC
socket on the circuit board. Plug the power supply in the mains to power up the system.
8. Start manual regeneration of the system. Scroll regeneration to backwash if it isn’t the
1st step of the sequence. When the control valve starts the backwash, turn on mains water
supply slightly at rst. Air will be displaced from the system via drain line while the pressure
tank is being lled with water. When the tank is full, water will start owing down the drain
line. At this point, fully open mains water supply. Carefully inspect the system for leaks.
Let the system complete regeneration, then perform one more manual regeneration.

3.3. Procedure for installing an FU Twin or FK Twin systems
FU Twin and FK Twin systems are equipped with CE Twin control valve. The valve has two
additional side ports for connecting to the twin tank. Twin systems provide uninterrupted
treated water supply without falling back on raw water when the system is regenerating.
1. Install both FRP tanks on rm level surface capable of supporting their weight. Put riser
pipes with bottom distributors down in each pressure tank. Ensure that top ends of riser pipe
are level with the top openings of the FRP tanks (within ±5 mm).
2. Put a plug or cap on the top ends of the riser pipes to prevent getting any media inside
the pipes. Pour the resin in both tanks using the funnel. When loading each tank, keep riser
pipe vertical. If the pipe tilts, restore it to straight vertical direction. When nished, rinse the
threads of tank openings with water to remove any beads of media stuck in the grooves.
3. Lock the top distributor in circular slot at the bottom of the control valve’s shank. Install
control valve on the lead tank. Mate the distributor with top end of riser pipe, then screw the
control valve in the tank opening. Rotate the tank if necessary so that the control valve’s
side ports face the second tank. Attach second top distributor to the In-out head and screw
the head on the second tank. Use the two interconnectors to connect In-out head to the
control valve. Fix the coupling nuts snugly.
4. Connect drain pipe to the male threaded drain outlet of the control valve. Run the drain
pipe to oor drain or gravity drain pipe socket. Secure the drain pipe end above the receiving
xture with at least 1″ air gap.
5. Place the brine tank beside the two FRP tanks. Install exible tube in the control valve’s
brine inlet and run it to the brine tank. Remove tank lid and brine well cap, pull the end of
the tube inside and connect it to the brine valve, then re-assemble in reverse order. Fill the
brine tank with salt pellets at least half full.
6. Mount the pipe thread elbow adapters to the control valve’s In and Out ports and tighten
the coupling nuts. Do not put any mechanical load on ttings or use them to support pipes.
Connect the system to water supply and downstream pipework without turning on the water
supply. Do not confuse In and Out ports. They are embossed with direction arrows.
7. Remove the front panel by pulling the locking tabs on the left and right side. Run the
power cord through the cord guide in the control valve’s backplate and connect it to 12 VAC
socket on the circuit board. Plug the power supply in the mains to power up the system.

8. Start manual regeneration of the system. Scroll regeneration to backwash if it isn’t the
1st step of the sequence. When the control valve starts the backwash, turn on mains water
supply slightly at rst. Air will be displaced from the system via drain line while the tank is
being lled with water. When the tank is full, water will start owing down the drain line.
At this point, scroll through the rest of the regeneration sequence to end regeneration.
Then start one more manual regeneration and scroll to backwash if it isn’t the 1st step. Wait
until all air is displaced from the second tank. Then scroll through the rest of regeneration
sequence to end regeneration.
Fully open mains water supply. Carefully inspect the system for leaks. Manually initiate two
more complete regenerations, one after another.
3.4. Procedure for installing a DFU Twin or DFK Twin systems
DFU Twin and DFK Twin systems are equipped with two CE control valves, a three-way
Motorized Alternating Valve, and a communication cable for connecting the control valves.
The three-way MAV routes water from the lter that is currently in service to the outlet, while
keeping the reserve lter shut o󰀨. Lead lter’s control valve actuates the MAV and controls
the reserve lter.
Twin systems provide uninterrupted treated water supply without falling back on raw water
when the system is regenerating.
1. Install both FRP tanks on rm level surface capable of supporting their weight. Put riser
pipes with bottom distributors down in each pressure tank. Ensure that top ends of riser pipe
are level with the top openings of the FRP tanks (within ±5 mm).
2. Put plugs or caps on the top ends of the riser pipes to prevent getting any media inside
the pipes. Pour the resin in both tanks using the funnel. When loading each tank, keep riser
pipe vertical. If the pipe tilts, restore it to straight vertical direction. When nished, rinse the
threads of tank openings with water to remove any beads of media stuck in the grooves.
3. Lock the top distributor in circular slot at the bottom of the control valve’s shank. Install
control valve on the lead tank. Mate the distributor with top end of riser pipe, then screw the
control valve on. Install the second control valve on the reserve lter tank in the same way.
4. Connect drain pipe to the male threaded drain outlet of each control valve. Run the
drain pipes to oor drain or gravity drain pipe socket. Secure the drain pipe end above the
receiving xture with at least 1″ air gap.

INSTRUCTION MANUAL ECOSOFT®MEDIA SYSTEMS
5. Place the brine tank beside the FRP tanks. Install exible tube in both control valves’
brine inlets, join them with a tee connector and run a third piece of exible tube from the tee
to the brine tank. Remove tank lid and brine well cap, pull the end of the tube inside and
connect it to the brine valve, then re-assemble in reverse order. Fill the brine tank with salt.
6. Mount the pipe thread elbow adapters to the control valve’s In and Out ports and tighten
the coupling nuts. Do not put any mechanical load on ttings or use them to support pipes.
Connect both lters to water supply via In ports without turning on the water supply. Connect
the Out ports to MAV’s A and B ports. Then connect port C of the MAV to the downstream
pipework. Do not confuse In and Out ports. They are embossed with direction arrows.

7. Remove the front panel of each control valve by pulling the locking tabs on the left and
right side. Run the power cord through cord guide in each control valve’s backplate and
connect it to the 12 VAC socket on the circuit board. Connect MAV cord to the lead lter’s
MAV socket. Connect the lead tank’s circuit board to the reserve tank’s circuit board with the
3-wire cable by plugging it in the COMM CABLE sockets in each circuit board. Make sure all
external cables are routed through the guides in control valve backplates, so the front panel
can be put back on. Plug both power supplies in the mains to power up the system.
8. Enter programming menu and setup both control valves for Twin operation (see
programming instructions in the next section).
9. Start manual regeneration of the lead lter by holding REGEN button for 5 seconds.
Scroll regeneration to backwash if it isn’t the 1st step of the sequence. When the control
valve starts the backwash, turn on mains water supply slightly at rst. Air will be displaced
from the system via drain line while the pressure tank is being lled with water. When the
tank is full, water will start owing down the drain line. At this point, scroll through the rest of
the regeneration sequence to end regeneration.
Then start one more manual regeneration (by holding REGEN button of the lead lter) and
scroll to backwash if it isn’t the 1st step. Wait until all air is displaced from the second tank.
Then scroll through the rest of regeneration sequence to end regeneration.
Fully open mains water supply. Carefully inspect the system for leaks. Manually initiate two
more complete regenerations, one after another.
3.5. Procedure for installing a DFU Duplex or DFK Duplex systems
DFU Duplex and DFK Duplex systems are equipped with two CE control valves, two No
Hard Water Bypass Valves, and two microswitches with linking cables. The microswitches
link each control valve to the other control valve’s microswitch socket. This prevents both
lters regenerating simultaneously – if one of the lters is regenerating, the other will not
regenerate until the former nishes. No Hard Water Bypass Valves prevent raw water from
being drawn when any of the lters regenerate.
Duplex systems provide uninterrupted treated water supply with the peak ow capacity of
both lters online, low ow capacity of one lter online one o󰀪ine for regeneration.
1. Install both FRP tanks on rm level surface capable of supporting their weight. Put riser
pipes with bottom distributors down in each pressure tank. Ensure that top ends of riser pipe
are level with the top openings of the FRP tanks (within ±5 mm).
