par-ameter of softener should be adjusted accordingly.
●When the water treatment capacity is too low, please check the resin. If the reason
is short of resin, please add; if the resin is turn to reddish brown or broken, please
replace.
●Test water periodically to verify that system is performing satisfactorily.
●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.
●Ensure that there is solid salt all the time in the brine tank in the course of using,
when this valve is used for softening. The brine tank should be added crytalline
coarse salts only, at least 99.5% pure, forbidding use the small salt.
● Do not put the valve near the hot resource or surroundings with high humidity,
corrosive intense magnetic field or intense librations environment. And do not leave it

Residential softening system
Ion exchange equipment
Boiler softening water system
RO pretreatment softening system, etc.
1.2. The Product Characteristics
●Simple structure and reliable sealing
It adopts hermetic head faces with high degree pottery and corrosion resistance for
opening and closing. It combines with Service, Backwash, Brine & Slow Rinse, Brine
Refill and Fast Rinse.
●No water pass the valve in regeneration in single tank type.
●Manual function
Realize regeneration immediately by pushing at any time.
●Long outage indicator
If outage overrides 3days, the time of day indicator "12: 12" will flash to remind
people to reset new time of day. The other set parameters do not need to reset. The
process will continue to work afterpower on.
●LED dynamic screen display
The stripe on dynamic screen flash, it indicates the control valve is in service,
otherwise, it is in regeneration cycle.
●Buttons lock
No operations to buttons on the controller within 1 minute, button lock indicator
lights on which represent buttons are locked. Before opreation, press and hold the
and button for 5 seconds to unlock. This function can avoid incorrect operation.
● Interval backwash times
It could set up interval backwash times up-flow regeneration valve which means
several times of services but one time of backwash. The setting of interval
backwash time depends on the local water turbidity. (The lower the turbidityis, the
longer of the interval backwash time can be set).
●It can choose time clock type or meter type by program selection
When all symbols light on, press and hold and buttons for 5 seconds to enter
the menu of valve model selection. Please set the program type in accordance with
the product type. (Time clock type by days or hours or meter type) (Notice: The meter
type product has one flow meter and probe wire,but the time clock type doesn't have).
Four kinds of meter type can be selected
Model Name Instruction
A-01 Meter Delayed It will not regenerate although the available volume of treated water drops

●There are two kinds of regeneration mode for time clock type
When the program is set to time clock type by days, it can be changed to be by
hours by dialing the red switch on main control board to "1" (Refer to the figure in 18).
Pointing to "ON" mean the time clock type service by days. (Note: After dialing the
switch, please restart the power)
●Interlock function
It has a function of interlock to realize only one valve in regeneration but the other
valves are in service while srveral valves parallel in system. In multi-steps treatment
system such as RO pre-treatment, when serveral valves are in series, there is only
one valves in regeneration or washing to ensure pass water all the times while
different valves in regeneration or washing. (Application refer to Figure 3-9)
Signal output
There is a signal output connector on main control board. It is for controlling external
wiring (Refer to Figure Figure3-1 to Figure 3-8)
There are two kinds of output mode: b-01 Mode: Turn on start of regeneration and
shut off end of regeneration; b-02 Mode: Signal available only intervals of
regeneration cycle and in service.
●Remote handling input
This connector can receive external signal, used together with PLC, and computer
etc. to control the valve. (Applicatin refers to Figure 3-11)
●Pressure relief output
The valve will cut off feeding water to drain line when it switches in regeneration
cycles(Same as signal output b-02). Thus in some water treatment system, e.g. Deep
Well, one booster pump was installed on the inlet to increase the system water
feeding pressure, this cut-off will cause pressure on inlet rising too fast to damage the
valve. Pressure Relief Output can be used to avoid this problem. (Application refers to
Figure 3-10)
●Maximum interval regeneration days
Under the situation of service reaching the setting days and the volume not yet, it
could enter into regeneration process forcibly when current time is the same as
regeneration time.

Instruction: If system requires no hard water flowing from outlet in regeneration cycle
(Mainly for no hard water flow out when valve is switching or valve in backwash or
brine drawing status), a solenoid valve could be installed on outlet, the wiring refer to
Figure 3-1.
(Connect to Control Protection Case)
Figure3-1 Writing of Solenoid Valve on Outlet
Function:
When valve is in service status, if soft water tank is short of water, solenoid valve will
open to supply soft water, but if water tank has enough water, solenoid valve will
close, so no soft water will be supplied into soft water tank.
When the valve in backwash or other regeneration status, there is no signal output.
So, solenoid valve will close, and no raw water flows into soft water tank.
②Control Inlet Solenoid Valve( Set b-02)
Instruction: When inlet pressure exceeds 0.6MPa, install a solenoid valve on inlet.
Control mode is b-02. Pressure is relieved when valve switching, the wiring refers to
Figure 3-2. As Figure 3-3 shows, it also can use the pressure relief connector to work.

2) Liquid Level Controller Controls Inlet Pump( Two-phase motor)( Set b-01)
Instruction: For the system using well or middle-tank supplying water, switch of liquid
level controller and valve together control pump opening or closing. The wiring refers
to Figure 3-5:
Figure 3-5 Writing of Liquid Level Controller Controlling Inlet Pump
Function:
When valve in service status, if water tank is short of water, pump starts working, if
not, the switch of liquid level controller is closed, so pump doesn't work.
When valve is in backwash, or other regeneration status, no matter what is water
condition in water tank. Open the pump to make sure there is water on inlet. As there
is no water flows out of outlet in regeneration cycle, it ensure no water fill into brine
tank. A liquid level controller at the top opening of well or in middle water tank in RO
system can protect pump from working without water in case of out of raw water.

3) Liquid Level Controller in Water Tank Controls Inlet pump (Three-phase) (Set b-01)
4) Control Inlet Booster Pump( Set b-01 or b-02)
Instruction:If inlet water pressure is less than 0.15MPa, which makes rinse drawing
difficult, a booster pump is suggested to be installed on inlet. Control mode set to b-
01. When system in regeneration cycle, booster pump is open, the wiring refer to
Figure 3-7. If the booster pump current is bigger than 5A, the system needs to install
a contactor, the wiring refers to Figure3-8

Instruction:
In the parallel water treatment system, it ensures only one valve in regeneration or
washing cycle and (n-1) valves in service, that is, realizing the function of supplying
water simultaneously and regenerating individually, the wiring refers to Figure3-9.
In the series water treatment system(Second grade Na+ Exchanger or RO pre-
treatment system), it ensures only one valve in regeneration or washing status and
there is/are water(s) in service.

C. Pressure Relief Output
In adopt inlet booster pump or well supply systems, valve switching will increase the
system water feeding pressure, the motor can't rotate. Installing the solenoid valve in
inlet pinepipe,connecting with the drain. When the valve switching, the pressure relief
solenoid valve opens, the water flows to the drain. Avoiding the system closed, which
will cause the inlet pressure rising too fast to damage the valve.The wiring refer to
Figure3-10

D. Remote Handling Connector
When the valve is used to make pure water or other system that can be monitored
online or connected to a PC, etc., when the conductivity or other parameters reach
the set value or the PC sends a signal and needs system regeneration, it can be
provide a signal to remote handling connector of main control board by the signal line,
which can make the valve regenerate immediately. The connector receiving the signal
is equivalent to pressing the manual button. The wiring refers to Figure3-11:
E. Interlock System
2 or more than 2 valves are interlocked connecting in one system and all valves are
in service but regenerate individually. The wiring refer to Figure3-12.

F. Series System
This is a 2 or more than 2 valves system,all in service, with one flow meter for the
entire system. For the time type valve, the regeneration time should be set and
adjusted to the Max; for the volume type valve, connect its signal output connector with
the remote handling connector of the time-type valve. That can realize the function of
supplying water simultaneously and regenerating orderly.The wiring refer to Figure 3-
