INTRODUCTION
Your WATEX CMS series water softeners are precision built high quality products.
This is an effective solution for water hardness, iron, ammonium and turbidity reduction.
These units will deliver conditioned water for many years to come, when installed and operated properly. Please study this
manual carefully and understand the cautions and notes before installing. This manual should be kept for future reference. If you
have any questions regarding your water softener, contact your local dealer or WATEX.
REQUIREMENTS
Please note that the water SOFTENER is heavy and fragile; the fiberglass tank cannot stand mechanical shocks.
Any mechanical shock can affect the operation of the softener. It is not recommended to roll or turn the softener upside down.
Use a wheeled platform to move the softener. Where it is not possible, move it together with another person using your hands.
Moving by hands, it is recommended to grab the top behind the control valve housing (the place where the control valve
connects to the tank) and the bottom behind the blue fiberglass tank.

*The amount of water for regeneration depends on water hardness and iron, turbidity, ammonium concentration.
** Softener Capacity depends on water hardness and iron, turbidity, ammonium concentration and should be calculated for each
water separately to get the best results and to reduce salt consumption and water for regeneration.
Please contact to your local dealer or WATEX to program the right capacity.
Important notes:
Softener does not remove smell, organics, bacteria or viruses.

On the filtering tank of the filter is installed the CLACK WSCI control valve, which controls automatic regeneration of the
softener.
The control valve housing is made of plastic alloy. The control panel is located in front of the filter, and the water supply and
sewerage connections are in the rear.
The control valve is operated by voltage of 220 V. The control valve has the motherboard, which stores and regulates all the
rinse process parameters. To rinse the filter the voltage is fed from the motherboard to the built-in motor that moves a cylindrical
detail built-in the unit into a certain position.
On the left part of the control valve housing at the outlet manifold is a built-in meter that counts the quantity of water consumed.
The rinse algorithm is based on the volume of water consumed, which is counted by the built-in meter. Easy locking drain/ brine
clip for easy removal. Standard ¾” Male NPT 90° drain elbow that swivels 180° for easy orientation.
3/8” Parker Liquifit brine elbow that swivels 270° for easy orientation. Built in internal flow meter off the side of the outlet port
for easy maintenance.
2.1.2. Brine tank
The brine tank is intended for storing Sodium Chloride NaCl (salt tablets). There are several components inside brine tank: a
safety float, brine well, grid plate. Normally the water level should be about 1/3 of the brine tank height. This is sufficient to
dissolve part of the NaCl regeneration cycle.
Brine well: The brine well is a cylindrical barrier that keeps the salt or potassium chloride
away from the safety float and air check valve which allows them to operate without any
obstructions.
Brine Tank Safety Float: A safety float is included inside the brine tank to ensure that salt
water does not overflow onto the floors if the injectors on the control valve get blocked up.
Float level can be adjusted, but in normal operation it is not necessary.
Grid plate (salt platform): A grid plate is placed at the bottom of the brine tank. The grid
plate acts as a tool to displace the water. This allows more water to flow into the brine tank
to ensure that enough brine solution is available during the regeneration process.
Salt must be periodically added to the brine tank, it should be located where it is easily
accessible.
Fill salt cabinet when water level is above salt level. Do not mix different types of salt. If iron is present in your water, use a salt
with an iron-cleaning additive to help keep resin clean. You may also use a resin cleaner on a monthly basis in place of salt with
cleaning additives. If iron is not present in your water, a clean pellet, solar or cube type salt is recommended.
The use of rock salt is not recommended because it contains impurities that can plug up the injector assembly.
2.1.3. Resin tank
The filter tank is filled with ion exchange resin (cationic), which reduces hardness and iron concentration in water. Capacity of
filter material is calculated according to amount of resins and raw water quality. When capacity is exhausted, regeneration by
salt is performed.
7
OPERATION MODES
WATEX CMS softeners have two operation modes: Service and Regeneration mode.
When the softener is In Service it is flowing water through the system and removing hardness minerals from your water.
Regeneration have 5 cycles:
1. First Backwash is a rapid upward flow of water that loosens the resin bed and flushes iron particles, dirt and sediments
filtered in the bed out to the drain.
2. Brine Draw is the process in which brine is drawn out of the brine tank and passed through the resin in a downward
direction. This rinses the resin and large amounts of sodium ions replace the hardness ions accumulated during service.
3. Second backwash. After brine is completely removed from the brine tank into the resin tank the brine floating valve closes.
Water replaces any remaining brine from the resin, flushing hardness ions removed from the resin to drain.
4. Rinse is a fast flow of water down through the resin tank that follows a second Backwash. This flushes all remaining brine
from the tank and packs the resin bed for softening efficiency.
5. Fill. Brine is water saturated with large amounts of a salt (sodium chloride). During brine fill, water flows into the salt
storage area after each regeneration and dissolves salt. During the regeneration process, hardness ions on the resin beads are
replaced or exchanged for sodium ions from the brine solution.
8
INSTALLATION
General conditions
The softener must be placed on the flat, leveled surface.
It is recommended to install the softener in the technical room with sound absorbing, because during the regeneration (usually at
night), the flow of water to the sewers could be heard.
The control valve and connection fittings are not intended for supporting the weight of the water supply system.
All sanitary-technical works to be performed in accordance with local plumbing and electrical codes.
Filter must be provided with a continuous supply of water, which does not differ in quality and quality within 30% and has the
pressure range of 2.0 to 3.5 bar.
The distance between the drain and the water conditioner should be as short as possible.
The room temperature must not be lower than + 5 °C and not higher than 45 °C.
Do not use for the filter connections petroleum jelly, oils, hydrocarbon lubricants or spray silicone. Silicon grease can be used on
black o-type sealing rings, but it is not necessary.
Nuts and bolts have been designed so they can be unscrewed or tightened by hand or special plastic key. If you need to unscrew
the tightened nuts or couplings, you can use pliers. However, take care not to damage the plastic parts. Do not use wrenches or
socket wrenches to tighten or loosen.
Do not place the screwdriver into sleeve/cap openings and do not strike with a hammer!
Teflon tape is not necessary for sewer and reagent connection fittings.
Place the water filter so that the distance between the drainage outlet and the filter is minimized.
Perform a general preventive maintenance at least once a year.
Water pipe connection In the rear of the water filter is the water supply connection. Each connection has
the inflow and outflow indicating arrows. If you look at the filter from the front, on
the right side is the inflow and on the left side is discharge. The filter’s connection
to the mains outer thread size 1 '' (inch), of both input and output. Plastic threaded
fitting is of a screw type and it can freely rotate the ring, keeping the density.
Therefore, there is no need for very powerful (sufficient hand strength) tightening
of the bolts on the control valve housing.
Use of Teflon tape on the plastic threads is a must.
The material of the piping, which connects to the filter, does not make significant
difference. Most important is that the filter does not bear the weight of the water
supply system.
Filter can be connected with the cast iron, glued, PVC screw-fastening pipes. It is
also possible with flexible metal pipes, soldered brass pipes.
Note: soldering of pipes must be carried out before connection to the control valve plastic fittings failing to follow this rule can
result in internal damage of the plastic fittings and they will not provide consistency of connection.
Soldering fittings must be cooled down. Avoid soldering grease contact with any connecting fitting parts.
For the water filter, it is recommended to install a bypass valve, as shown in the figure, and sample valves before inflow and
outflow as well.
During the normal operation, bypass valve is closed, but the input and an output valves are open.
During the preventive maintenance works on the installation or filter repair, the not purified water can be supplied to the
consumers.
It is recommended to install the sampling valve before and after the filter to compare /determine the quality of raw water and the
just- purified water. It is also advisable to install pressure gauges before and after the filter to control the pressure loss in the
installation.
In order to enhance the durability of the filter first it is recommended to install a mechanical filter that prevents sand particles,
which can be lifted out of the hole and to lead to clogging the parts of the filter.
9
Drainage connection
The filter requires to be connected to the sewer in order to ensure regular rinsing. During the rinsing time, the air bag of the filter
is removed along with the accumulated dirt (mud, iron, sand, clay, etc.).
Drainage connection points are located at the top of the control valve. We recommend using a garden hose for drainage of
rinsing water from the filter to the common sewage system.
Note: the bend of the sewer connection has the sealing ring; it is possible to turn it in the desirable direction. Turning angle is
270o.
Important: Ensure that the drainage pipe during rinsing is not dropping
out. Secure it!
Important: Make sure the garden hose is not folded, because it will reduce
rinsing water flow and the filter is likely to have incomplete rinsing, which
can lead to poor water supply.
Drainage pipe can be placed in the common sewer around 0.5 meters above
the control valve, but during the first rinses watch if the full rinsing of the
filter is really going on.
If there is no complete rinsing, consult with "WATEX" technical center.
Important: Gravity Drainage pipe shall be not less than D40.
Important: Never drive the drain hose directly into drains or the receiver.
Always allow air access between the drain hose and the tank to avoid
backflow.
Important: To prevent the sewer smell come into the filter and cause
bacteriological contamination of the filter before entering the sewage
system it is recommended to create hydro seal or siphon.

Reagent tank connection
The kit contains a reagent tank as well as a 3/8 "connecting pipe. The flexible plastic tube is placed in the reagent container
under the lid. The reagent tank should be placed next to the filter tank. Can be placed on any side of the filter tank.
The reagent tank has a plug that is placed in the plastic container of the reagent tank. Remove the float and remove the transport
rubber put on the bottom of the float. Threads do not have to use packaging materials.
Remember!
The regeneration tank will need to be filled with a reagent on a regular basis, so it is advisable to place it where it is easily
reachable.
The control panel is shown in the drawing, highlighting the connection point of the reagent supply line. The pipeline connection
is carried out as follows: 1.Unlock the control unit reagent by removing the
clamp and removing the reagent attachment elbow.
2. Pull the pipe through the nut
3. Place the cylindrical insert on the end of the tube,
then make two consecutive rings.
4. Insert the end of the tube into the bend hole to the
end and tighten with the nut. Manual engagement.
5. Place the reagent joint in the opening and place the
clamp.
Note: The reagent connection elbow has a sealing
ring, it can be rotated in the desired direction.
Turning angle is 270o.
6. The end of the second tube is drawn through the
hole in the side of the reagent tank and added in the
same manner as in paragraphs 2, 3 and 4.
When the equipment is connected to the water
supply, drainage and reagent tanks, in the reagent
container, fill salt tablets (NaCl) in Brine tank.
11
Bypass (option)
•Directional shut-off arrows for flow: Normal, Bypass, Diagnostic mode, Shut-off mode.
•Radial seals allow side-to-side and up/down minor plumbing misalignments, connections need only hand tightening.
•One internally lubricated O-ring on rotor creates less friction.
Bypass Valve Operation
12
External In-Line Mixing valve (option)
You can use the external in-line mixing valve on water softeners to blend a desired amount of hardness back in the line or use it
on a carbon filter to blend a small amount of chlorine back in the line.
Electrical connections
The softener is supplied with electricity transformer (AC adapter), which operates at 220 V. Power supply to the softener must
be continuous. AC adapter is designed for dry places only.
Note: All electrical connections must comply with local regulations.
To ensure a continuous supply of electricity from the source located not farther than 2 meters from the water softener.
Adapter wire must be connected inside the control valve.
1. Remove the front cover of the control valve.
2. At the top of release the middle mounting tab that keeps the motherboard frame to the control valve.
3. On the right side of the plastic wall of the control valve there is a hole through which to pull the transformer’s
(adapter’s) tip.
4. The tip to be connected to the contact terminals at the right lower part of the motherboard.
5. The rest of the cable should be placed along side the frame of the motherboard behind the specially designed clamps.
6. Push back the motherboard-mounting frame to fastening tab and secure it in the original position.
7. Install the front button cover.

Manual regeneration
Sometimes you need to make regeneration earlier before the system determines that it is necessary; it is usually referred to
as manual regeneration. It is possible that there was a period when the water has been used more than usual, for example, where
there have been more visitors or more linen have been washed.
To initiate a manual regeneration in the set deferred regeneration time press and release REGEN. Then the display will flash
the words "REGEN TODAY", indicating that the system will initiate regeneration before the pre-set regeneration. If you have
pressed the "REGEN" button by mistake, re-pressing the button will cancel the request.
