●To ensure normal operation of the valve, please consult with professional installation
or repairing personnel before use it.
●If there are any of pipeline engineering and electric works, there must be finished by
professional at the time of installation.
●Do not use the control valve with the water that is unsafe or unknown quality.
●Depending on the changing of working environment and water requirement, each
parameter of softener should be adjusted accordingly.
●When the water treatment capacity is too low,please check the resin. If the reason is
shortage of resin, plsease add; if the resin is turn to reddish brown or broken, please
replace.
●Ensure that there is solid salt all the time in the brine tank in the course of
using,when this calve is used for softening. The brine tank should be added the
crystalline coarse salt only, at least 99.5% pure, forbidding use the small salt.
●Test water periodically to verify that system is performing satisfactorily.
●Sodium used in the water softening process should be considered as part your
overall dietary salt intake.Contact doctor if you are on a low sodium diet.
●Do not put the valve near the hot resource,high humidity, corrosive, intense magnetic
field or intense librations environment. And do not leave it outside.
●Forbidden to carry the injector body.Avoid using injector body as support to cary the
system.
●Forbidden to use the brine tube or other connectors as support to carry the system.
●Please use this product under the water temperature between 5-45 ℃, water
pressure 0.2-0.6MPA. Failure to use this product under such conditions voids the
warranty.
●If the water pressure exceed 0.6Mpa, a pressure reducing valve must be installed in
front of the water inlet. While, if the water pressure under 0.2Mpa, a booster pump
must be installed in front of the water inlet.
●Do not let children touch or play, because careless operations may cause the
procedure changed.

Ro pretreatmet softening system, etc.
1.2.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.
▷Variety of Installation methods
Use side-mounted connector can change HT-SAV02 from top mounted to side
mounted,and screen is movable.
▷No water passes the valve in regeneration in single tank type
▷Manual function
Realize regeneration immediately by pressing at any time.
▷Long outage indicator
If outage overrides 3 days, the time of day indicator “ 12:12 ” will flash to remind
people to reset new time of day. The other parameters do not need to reset. The
process will continue to work after power on.
▷LED dynamic screen display
The stripe on dynamic screen flash, which indicates the control valve is in service;
otherwise, it is in regeneration cycle.
▷Buttons lock
No operations to buttons within 1 minute, button lock indicator light on which
represents buttons are locked. Before operation, press and hold the and
buttons for 5 seconds to unlock. This function can avoid incorrect operation.
▷It can choose time clock type or meter type by program selection.
Can realize interchange between time clock type by day or by hours and meter type by
dialing a switch on main control board. (Check figure on PI8)(Attention:After dialing the
switch,it needs to reconnect the power. The meter type product has one flow meter and
flow meter cable, but the time clock type product doesn't have.)
▷Four kinds of meter type can be selected (Suit for HT-SAV02)
4

Mode Name Instruction
A-01 Meter delayed
regeneration
Regenerate on the day although the available volume of
treated water drops to zero(0). Regeneration starts at the
regeneration time.
A-02 Meter immediate
regeneration
Regenerate immediately when the available volume of
treated water drops to zero(0).
A-03 Intelligent meter
delayed regeneration
Meter delayed regeneration type, but by setting resin
volume, feed water hardness, regeneration factor, the
controller will calculate the system capacity.
A-04
Intelligent meter
immediate
regeneration
Meter immediate regeneration type, but by setting resin
volume, feed water hardness, regeneration factor, the
controller will calculate the system capacity.
▷Interlock Function
It has a function of interlock to realize only one valve in regeneration but the other valves are
in service while several valves parallel in system. In multi-steps treatment systems such as
RO pre-treatment, when several valves are in series, there is only one valve in regeneration
or washing to ensure pass water all the times while different valves in regeneration or
washing.
▷Signal output
There is a signal output connector on main control board. It is applied for controlling external
wiring(Refer to Figure from Figure 3-1 to Figure 3-8). There are two kinds of output modes.
b-01 Mode: Turn on when start regeneration and shut off at the end of regeneration; b-02
Mode: Signal is available only at intervals of each status. Refer to below figure:

▷Remote handling connector
This connector can receive external signal, used together with PLC, and computer etc.
to control the valve remotely. (Application refer to Figure 3-11)
▷Pressure relief connector
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 refer 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.
▷All parameters can be modified
According to the water quality and usage, the parameters in the process can be
adjusted.
1.3. Service Condition
Valve should be used under the below conditions:
Items Requirement
Working conditions Water pressure 0.2MPa -0.6MPa
Water temperature 5℃-45℃
Working environment
Environment
temperature 5℃-45℃
Relative humidity ≤95%(25℃)

Water hardness First Grade Na+<6.5mmol/L;
Second Grade Na+<10mmol/L
Free chlorine <0.1mg/L
Iron2 <0.3mg/L
CODMn <2mg/L(O2)
In the above table,First Grade Na+ represents First Grade Na+ Exchanger.Second
Grade Na+ represents Second Grade Na+ Exchanger.
▷When the water turbidity exceeds the conditions, a filter should be installed on the
inlet of control valve.
▷When the water hardness exceeds the conditions,the outlet water hardness will hardly-
reach the requirement of boiler feed water(0.03 mmol/L).It is suggested to adopt second
grade softener.

C.Pipeline installation
① Install control valve
a. As the Figure 1 - 1 shows, select the riser pipe
with 50mm OD, take GB standard riser pipe as an
example glue the riser pipe to the bottom strainer
and put it into the mineral tank, cut off the
exceeding tube out of tank top opening and round
it. Plug the riser tube in case of mineral entering .
b. Fill the resin to the tank,and the height is
accordance with the design code .
c. Screw top strainer connector to valve body with
five pieces of screws.
d.Insert the top strainer to the valve.
e.Insert the riser tube into control valve and screw
tight control valve.
Note :
●The length of riser tube should be neither higher 2 mm nor lower 5 mm tank
top opening height , and its top end should be rounded to avoid damage of O-
ring inside the valve.
●Avoid filling floccules substance together with resin to the material tank.
●Avoid O-ring inside control valve falling out while rotating it on the tank.

As Figure 1-2 shows, put the sealing ring into nut of flow meter, screw in water outlet;
insert the senor into flow meter.
③Pipeline connection
a.As figure 1-3 show, install a pressure gauge in water inlet.
b.Install valve A, valve B, valve C and valve D in the inlet, outlet, inlet and outlet pipeline.
The valve D is sampling valve.
c.Install a check valve on outlet pipeline.
d.Inlet pipeline should be in parallel with outlet pipeline.Support inlet and outlet pipeline
with fixed holder.
Note :
●If the water outlet or water tank is installed higher than control valve or is used in
parallel interlock system with multi-outlets, a liquid level controller must be
installed in brine tank or a check valve must be installed on outlet. Or else, the
water in water outlet or water tank will flow backwards into brine tank when
backwash.
●If making a soldered copper installation do all sweat soldering before connecting
pipes to the valve. Torch heat will damage plastic parts.
●When turning threaded pipe fittings onto plastic fitting, use care not to cross
thread or broken valve.
●If the valve belongs to time clock type,there are no step②.
④Install drain pipeline
Insert drain line flow control into drain outlet and connect the drain outlet with the ani-
mated nut,as Figure 1-3 shows.
