Notice
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, 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 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 the clean water softening salts only, at least 99.5% pure,
forbidding use the small salt.
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 carry 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～

50℃，water pressure 0.15～0.6MPa. Failure to use this product under
such conditions voids the warranty.
If the water pressure exceeds 0.6Mpa, a pressure reducing valve must
be installed before the water inlet. While, if the water pressure under
0.15MPa, a booster pump must be installed before the water inlet.
It is suggested to install PPR pipe, corrugated pipe or UPVC pipe,
instead of TTLSG pipe.
Do not let children touch or play, because carelessness operating may
cause the procedure changed.
When the attached cables of this product and transformer are changed,
they must be changed to the one that is from our factory.

Up-flow Regeneration
Up-flow regeneration, salt and water savings. No hard water pass
and hard water pass options.
Soft Water Refill
System also in service when in brine tank refill (Means soft water
flows in outlet), save the regeneration time and regenerate more
efficient.
Big Water Flow Rate
Flow Rate will be not lower 4.7m3/h when pressure drop is 0.1MPa.
Historical Record can be Enquired

A-02 Meter Immediate: Regeneration happens when the capacity
reaches to zero.
A-03 Intelligent Meter Delay: The same delay function as A-01 but the
capacity is set by input of the Resin Volume and Feed Water Hardness.
The control valve calculates the gallons before regeneration.

B. Device location
①The filter or softener should be located close to drain.
②Ensure the unit is installed in enough space for operating and
maintenance.
③Brine tank need to be close to softener.
④The unit should be kept away the heater, and not be exposed outdoor.
Sunshine or rain will cause the system damage.
⑤Please avoid to install the system in one Acid/Alkaline, Magnetic or
strong vibration circumstance, because above factors will cause the
system disorder.
⑥Do not install the filter or softener, drain pipeline in circumstance which
temperature may drop below 5℃, or above 50℃.
⑦One place is recommended to install the system which causes the
minimum loss in case of water leaking.
C. Pipeline installation
①Install control valve
a.As the Figure 1-1 shows, select the riser pipe with 32mm OD, 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. Plug the riser tube in case of
mineral entering

MODEL73605 73605B 73605/41206L 73605B/41206L
11
Fill the mineral to the tank, and the height is accordance with the design
code.
b. Install the top distributor to the valve.
c. Insert the riser tube into control valve and screw tight control valve.
Note:
●The length of riser tube should not be lower 15mm than tank top
opening height, lower than 8mm is advisable, and its top end should be
rounded to avoid damage of O-ring inside the valve.
●Avoid floccules substance together with resin to be filled in the mineral
tank.
●Avoid O-ring inside control valve falling out while rotating it on the tank.
②Install bypass valve
As figure 2 shows, put the sealing ring into nut of animated
connector, and screw in water inlet and outlet.
Insert animated connector to bypass valve then insert in buckle.
Figure 2
③Pipeline connection
As figure 3shows, inlet pipe connect with inlet connector of bypass
via 1” NPT female connector. Outlet pipe connect
with outlet pipe of bypass via 1” NPT female connector.

MODEL73605 73605B 73605/41206L 73605B/41206L

④Install drain pipeline
a. As the Figure 4 shows, Insert drain line flow control into drain outlet.
b. Insert O-ring into O-ring slot of drain connector.
c. Insert drain hose connector into drain outlet.
d. Screw drain hose connector into drain outlet, and lock it.
e. Locate the drain hose well as the Figure4 show.
Notice
●Drain line pipe lower than valve is advisable, if the drain line pipe higher
2m than valve is permitted, and the pipe should not longer then 3m. Pipe
too high or too long both will impact brine.

MODEL73605 73605B 73605/41206L 73605B/41206L
13
●Be sure not connect drain with sewer, and leave a certain space
between them, avoid wastewater be absorbing to the water treatment
equipment, such as showed in the Figure4.
⑤Connect brine tube
a. As Figure5 shows, slide 3/8″brine tube hose connector over end of
brine tube.
b. Insert the filter net into the tube.
c. Insert tube bushing into the end of brine tube.
d. Tighten brine draw hose connector onto brine line connector.
e.Connect the other end of brine tube with the brine tank. (the liquid level
controller and air-blocker should be installed in the brine tank.)
Remark: The brine tube and drain pipeline should not be bended or
plugged.
