1. Product Profile
The product works manually to handle the softening or desalting by the multi-port valve. It
adopts food-grade cation resin to soften water with characteristics of high flow rate and good
softening effect, efficiently reducing calcium and magnesium ion content of tap water. After
the resin is saturated, manually controls the product to brine and conduct regeneration,
recovering the softening function of the resin. It can manually realize the function of service,
backwash, brine & slow rinse, brine refill and fast rinse.
2. Working Principle
Ion exchange technique is applied to the softener. It can realize the purpose of wiping off the
lime scale (Calcium carbonate and magnesium carbonate) through replacing the calcium ion
and magnesium ion by the sodium ion of the resin. According to the pre-set softening process,
the user can manually control the multi-port valve so as to realize softening, backwash, brine
& slow rinse, brine refill and fast rinse.

4.Function and Characteristics
1.
Manual control mode: In the operation of softeners, it needs to manually rotate the hand wheel
or handle of the multi-port valve to complete the cyclic processes of service, backwash, brine
and slow rinse, brine refill and fast rinse.
2.
Service: Under a certain pressure and at a certain flow rate, the raw water flows through the
equipment. In the process the calcium ion and magnesium ion of raw water are replaced by the
sodium ion of resin and attached to the resin, reducing the content of calcium ion and
magnesium ion and realizing the purpose of softening water.
3.
Backwash: After the resin is saturated and lose softening efficacy, the program start
backwashing before regeneration. On one hand, it can wipe off the broken resin and the
impurity attached to the surface of resin. On the other hand, the reversed flow direction can
loosen the tight resin and make it easier for the touch between resin particle and regeneration
liquid.
4.
Brine and slow rinse: The saline solulion of at a certain concentration and water are mixed and
flow through the resin. As the calcium ion and magnesium ion are replaced by the sodium ion,
the invalid resin will get regeneration and recover its original softening capacity.
5.
Brine refill: The brine tank is refilled with water to dissolve the salt so as to provide to
saturated brine for next regeneration.
6.
Fast rinse: Discharge the residual brine and compact the resin particle so as to reach the best
softening effect. By this step, the product automatically finishes one service cycle.

8.1. Installation Notice
※The product is prohibited to be tilted or laid down during the transportation, installation and
usage.
※Place the prduct on the flat surface that can bear the weight more than 300kg/㎡. Besides,
there are water inlet and water outlet, drain pipeline and sewage in the workplace.
※Generally, the products are installed in the villas, apartments, schools etc or connected with
the main water pipelines of other office and business premises; if installed outdoors,
protective measure should be taken to prevent it from freezing, sunburn and soaking.
※The product should be kept off circumstances with alkaline and acid substance or gases in
case of corrosion.
※The suitable pressure for softener is between 0.15Mpa and 0.6Mpa. If lower or higher than
the standard, a booster pump or a relief valve should be intalled to ensure the normal
operation of the equipment.
※One place is recommended to install the system which causes the minimum loss in case of
water leakage.
※Use reagent to measure the inlet water hardness, for the hardness is related to the softening
effect and softening cycle. This series of products should be used in those places where the
water hardness is lower than 450mg/L.
※Make sure a check valve is installed between the device and water heater when a heating
stove or water heater is connected behind the device, in case the hot water reflux cause
damage to the internal system of the product.
※Separate sewage is required for the drain of the device. There should be 5 to 10cm of space
between the drain pipeline and floor drain, in case the siphon causes damage to the valve by
the waste.(Installation refer to below picture)
3

※
Before installing the pipeline, please clean off the residual impurities and dust in the pipeline.
After the main water inlet is closed, connect it with the device.
※
All pipelines should meet the relevant regulations. The installation and connection should
comply with the local installation rules.
※Keep a certain operation space for adding salt, cleaning an maintaining.
8.2. Installation and Connection
※
The pipeline connection and installation should be carried out in accordance with "Water and
Sewage Pipeline Construction Standards". The inlet/outlet connector and pipeline connector
should be installed on the same axis. Be sure not to install the positions of inlet and outlet
reversely.
※
The affiliated DLFC should be inserted into the drain outlet. The inlet, outlet pipeline,drain
line and overflow pipeline should be connected in sequence and make sure there are no
leakage of every joint. It is suggested to use hose pipe to connect the softener with inlet,
outlet, drain connector and overflow connector. (Attention: the pipe fittings and valves
should be made of 304 stainless steel, alloy copper forging, or high strength engineering
plastics, etc. The iron valves and pipe fittings are forbidden to use.)
※
It is suggested to install a manual bypass valve between the main water inlet and inlet/outlet
of the device, making it convenient for intallation and maintenance. (Refer to the below
installation illustration).

※
For convenient maintenance, the device is suggested as the illustration shows.
Note: Install three ball valves to connect the control valve and inlet/outlet pipeline. Valve B is
connected with the inlet of the control valve, valve C to the outlet. When the valve body needs
fixing, open valve A, then close the valve B and valve C. Normally, just open valve B and C,
then close valve A.
※
The control valve should be placed higher than the floor drain. The sewage and overflow
pipelines should be less than 2 meter, and place them above the floor drain. No throttle
device should be installed on the drain line. The pipe sealing should be of PTFE only.
※
Each pipeline should be supported by an independent holder lest the weight and stress from
the pipeline cause damage to the control valve.
Note: Make sure drain pipeline and overflow pipeline are connected well andl closc to flow
drain which helps to drain rapidly.
8.3. Directions for Use
※
In the position switch of the multi-functional flow control valve, rotate the hand wheel or
handle by 360°clockwise or counterclockwise to make the pointer rotate to the responding
position so as to achieve the status of service, backwash, brine and slow rinse, brine refill
and fast rinse.
Notices:
The hand wheel or handle can only be rotated clockwise or counterclockwise, forbidden to
be rotated upward and downward.
In operation the hand wheel arrow must be pointed to the responding arrow, otherwise the
possible malposition will cause water channeling or insuffciency of flow rate.

Brine valve installation and usage:
The brine valve plays two roles in the whole system: First, under the brine and slow rinse
status, with the floating ball, the brine valve can prevent the air from being inhaled which may
affect the regeneration and usability. That is, the brine valve has the function of air check.
Second, under the brine refill status. the brine valve can control the volume of refilling water by
controlling the position of floater.
9.Usage Installation
After installing the device and setting the relevant parameters, please conduct the trial
running as follows:
※
For the first use after installation, the user should add regeneration salt to the brine tank, and
water of an amount enough for a saturation, so as to make the water and salt completely mixed
as saturated solution(26%). Then the user can start the system (Only when the device is put
into for the first time, the user needs such operation.)

※
Rotate the control valve to the Backwash status; slowly open the inlet valve to 1/4 position
(Avoiding to open the valve too quickly so as not to damage the device and make the resin
run off ) to slowly release the air from the resin tank; at this moment, you can hear the sound
of air-out from the drain pipeline. After the air is completely released, then open inlet valve
completely and conduct backwashing for 2~3 minutes, cleaning the impurities and broken
resin particles.
※
After the Backwash ends, rotate the hand wheel to Brine & Slow Rinse; under this status,the
salt will be absorbed from the brine tank into the resin and the resin is regenerated. After
absorbing the salt, the brine valve will close. The system will still conduct about 15 minutes
of slow rinse, wiping off the residual brine. The whole process will take about 40 minutes.
※
After the Brine & Slow Rinse ends, rotate the hand wheel to Brine Refill; the brine tank will
be refilled with water to dissolve the salt. When the level contoller reaches the required
height, the refilling will be stop. The new saturated brine will be used for next regeneration.
※
After the Brine Refill ends, rotate the hand wheel to Fast Rinse. The Fast Rinse lasts 3
minutes fast and will discharge the residual brine and compact the resin particle so as to reach
the best softening effect.
※
Take the sample outlet water to test whether it it qualified, if qualified, end Fast Rinse, and
rotate the hand wheel to Service.
Illustration: When the device is in regeneration cycle and the softened water ceases to flow
out from the outlet, then it is suggested to operate according to the reference time values. If
you want to end the step in advance, you can rotate the hand wheel to any other position.
During the trial running status, check each port. There should be no media flowing out.
Check each connection, no leakage.

10.Note
Before reading and understanding the manual instruction, please do not operate the device.
※Forbid installing the device near heat source or take anti-heat protective measures when
install near the heat source. It is also forbidden to connect the device with the hot-water
pipeline or the pipeline with the possibility of hot-water returning. Forbid the product
under the temperature lower than 1℃. Protect resin from freezing which may result in
resin broken and disabled.
※If the raw water fails to meet the standards of municipal tap water, such as the sediment
concentration or residual chlorine content exceed the stand, etc., the pretreatment device
should be installed before the device.(Such as Y type fliter, ultra filter, and so on.)
※During the operation, please check the brine tank regularly to ensure that there is brine in
the tank. And when adding brine, please make sure that volume of brine should be 2/3 of
the tank. When it is less than 1/3, please add brine in time. (Attention: make sure the
dissolving salt time is more than 6 hours so as to make the saline solution saturate)
※Please strictly use the salt of more than 99% purity only. Any salt with additive or large
particles is forbidden to add.
※Sodium used in the water softening process should be considered as part of your overall
dietary salt intake. Contact doctor if you are on a low sodium diet.
※Please use this product under the water temperature between 5~45 ℃, water pressure
0.15~0.6 MPa. Failure to use this product under such conditions voids the warranty.
※Without use for a long time or the pressure of the inlet water is instable, please close the
inlet port and turn off the power. Before using again, please firstly conduct a regeneration
cycle through manual operation so as to ensure the quality of soften water.
※If the water demand is increasing (Compared to usual demand) or the hardness of raw
water is rising. please reduce the regeneration cycle and increase the regeneration times,
ensuring the softened water yield.
※When using the softener for the first time or the device is idle for a long period, it is a
normal that the outlet water is yellow. Please put it into use after 2~3 minutes of rinsing.
※Sometimes the brine in the brine tank will forms salt bridge. That is, there is a space
under the brine which prevents the salt from being dissolved and hinders the resin
regeneration. It is suggested to check regularly. If there is salt bridge, please mash it.
※
As the product is constantly updating, it is possible that the real product does not
completely conform with the manual instruction. It is subject to the real product.
Special note: The water pressure of tap water is changeable(Normally the pressure in night
time is higher than day time.),so pay attention to each connection to check if there is any
leakage at the first two days after products installed.
