Preface
Thanks for choosing our softener series products. These products are featured by
good softening effects, stable performance, excellent appearance, compact structure and
simple handling, etc. They can meet the soften water demand of family washing, bathing,
cleaning and boiling, etc. Besides, they also can be applied to supplying high quality soften
water for institutions, schools, group companies, and so on.
1. Product Profile
The product is working automatically and intelligently. It adopts food-grade cation resin
to soften water with characteristics of big flow rate and good softening effect, efficiently
reducing calcium and magnesium ion content of tap water. After the resin is saturated, the
regeneration function will automatically control the product to brine and conduct
regeneration, recovering the softening function of the resin. It can automatically realize the
function of backwash, regeneration, brine refill and fast rinse without manual operations.
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
program, it can automatically control the open and close of each valve, so as to conducting
softening, backwash, regeneration, slow rinse, brine refill and fast rinse.
3. Assembly & Parts
●Integrated type structure (For example B type)

2
●Split type structure (For example D type)
4. Function and Characteristics
1. Regeneration starts automatically: According to the regeneration time and water treatment
capacity of one cycle, the system will start the regeneration program.
2. Hardness of raw water can be set: After inputting the hardness value, the control valve will

3
automatically calculate the system water treatment capacity and display on the LCD screen.
3. Water hardness can be adjusted: It can adjust the hardness of outlet water by adjusting the
bypass.
4. Automatic memory function: The parameters set by users, such as regeneration time, backwash
time, brine & slow rinse time, brine refill time, fast rinse time and so on, can be saved permanently no
matter how long the power is off. If power off is more than 3 days, it will always display this interface to
remind to reset the time of day (See below picture)
Time of Day
12:12
5. Language: Chinese or English can be chosen.After power connected within 6 seconds, press and
hold both and for 5 seconds under the service status, the system will turn into language
selection interface.
6. Buttons lock function: No operations to buttons within 1 minute, buttons are locked. Press and hold
the “ ”and“ ” buttons for 5 seconds to unlock. This function can avoid incorrect operation.
7. Regeneration mode is meter delayed type: Regenerate on the day although the available volume
of treated water drops to zero (0). Regeneration starts at the regeneration time. It can avoid the shortage
of water for regeneration.
8. Working automatically:
Softening: Under a certain pressure and flow rate, the raw water flow through the product, at the
same time, the calcium ion and magnesium ion of raw water are replaced by the sodium ion of resin,
reducing the content of calcium ion and magnesium ion and realizing the purpose of softening water.
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 on surface layer of
resin. On the other hand, the reversed flow direction can loosen the tight resin and make it benefit for the
touch between resin particle and regeneration liquid.
Brine & slow rinse: A certain concentration brine flow through the resin. Meanwhile, the calcium ion
and magnesium on the resin surface layer are replaced by the sodium ion, making the invalid resin
regeneration and recovering its softening capacity.
Brine refill: The brine tank is refilled with water to dissolve the salt so as to provide the saturated brine
for next regeneration.
Fast rinse: Discharge the residual brine and compact the resin particle so as to reach the best

4
softening effect. By this step, the product automatically finished one service cycle.
5. Application
The product can be used for treating the tap water or other qualified raw water.

7.2. The Installation and Usage of Brine Valve
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 affected 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.
7.3. The Installation and Usage of Bypass Valve (Optional)(Take
F70C/F70D as example, if you use the other model of bypass valve,
please refer to the appendix manual.)
The valve has the function of bypassing. When the piston is pushed to the position of inlet and outlet,
the valve is in service status; When it is at bypass position, the valve is in bypass status. It adopts quick
joint structure to connect the valve with bypass valve, with the characteristics of reliable sealing, quick
and convenient installation.(Refer to the below pictures)
7.4. The Operations of the Valve with the Function of Mixing Water (Only
for F79 & F82 valve)
If the users think the hardness of outlet water is too low, they can adjust the hardness by using the
function of mixing water according to the actual demand.
Operation: Anticlockwise rotates the adjusting bolt (As the picture shows). The wider angle is, the
higher outlet water hardness will be.

※Switch on power. Press and go in the Backwash status. Slowly open the inlet valve to 1/4
position (Avoiding opening the valve too quickly to damage the device and make the resin run off).At this
moment, you can hear the sound of air-out from the drain pipeline. After all air is out of pipeline, then
open inlet valve completely and conducting 2～3 minutes backwash, cleaning the foreign materials in
the resin tank until the outlet water is clean.
Backwash Status
※Press , turn the status from Backwash to Brine& Slow Rinse. Under this status, the brine will be
absorbed from the brine tank into the resin and the resin is regenerated. After absorbing, the brine valve
will close. The system will still conduct about 15 minute’s slow rinse, wiping off the residual brine. The
whole process will take about 40 minutes to finish.
Brine & Slow Rinse Status
※Press and turn into Brine Refill status. The brine tank will be refilled with water to dissolve the

salt. When the level controller reaches the required height, the refilling will be stopped. The new
saturated brine will be used for next regeneration.
Brine Refill Status
※Press and turn into Fast Rinse status, starting to Fast Rinse. About 3 minutes fast rinse will
discharge the residual brine and compact the resin particle so as to reach the best softening effect.
Fast Rinse Status
※When the sample outlet water is qualified, press and finish the Fast Rinse. Then the device
turns into Service status and start running.
Service Status
Illustration: Under regeneration cycle, the softener valve will stop flowing out from the outlet and each
status will be completed automatically according to the setting time. If you want to finish one step in
advance, you can press .
※During the trial running status, check each port. There should no mineral media flow out. Check each
connection, ensure there is no leakage.
※The time of backwash, brine & slow rinse, brine refill, fast rinse, etc. could be suggested by dealer or
professional personnel.
Notice: Under normal situation, user does not need to do any operation except adding a certain amount
of salt into the brine tank.

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 local 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 filter, ultra filter, and so on.)
※During the operation, please check the brine tank regularly to ensure there is brine in the tank.
And when adding brine, please make sure that salt level is higher than water level (see pictureⅠ). When
the salt level is lower 1/3 of water level(see picture Ⅱ) , please add in time. (Attention: Make sure the
dissolving salt time is more than 6 hours so as to make the brine saturate)

12
※Please strictly use the salt of more than 99% purity only. Any salt with additive or large particles is
forbidden to add.
※Please use this product under the water temperature between 5～45℃,water pressure 0.15～
0.6MPa. Failure to use this product under such conditions voids the warranty.
※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.
※Without being used 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.
※During the service of product, prevent water hammer happened. Do not make these operations,
such as quickly and fully opening valve, or quickly and fully closing valve or shut off water pump, etc.
※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 soften
water yield.
※When use the softener for the first time or the device is idle for long period, it is normal that the
outlet water is yellow. Please put into use after 2~3 minutes’ 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.
※During regeneration period, there is no softened water for using. But if it still need water for using,
it is not suggested to bypass big quantity of hard water, it may affect the regeneration efficiency.
※If the display board display 12:12 and flashing, it means power off (more than 3 days) to remind to
