Notice
To ensure normal operation of the valve, please consult with
professionalinstallation or repairing personnel before use it.
If there are any of pipeline engineering and electric works, there must
be finished by professionalat 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 filter should be adjusted accordingly.
Test water periodicallyto verify that system is performing satisfactorily.
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 use the drain pipeline 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 productand transformer are changed,
they must be changed to the one that is from our factory.
For 53510(N75A) and 53510b(N75B1) product, in order to dismantle

easily, itis suggested to installthe strainer with M88×2 male thread.
1. Product Overview
1.1. MainApplication&Applicability
Used for filtering water treatment systems
Be suitable for
Residential filtering system
Swimming pool filtering equipment (N75A1/53510,
N75B1/53510B）
Carbon filter or sand filter in RO pretreatment filtering system
1.2. ProductCharacteristics
Simple structure andreliable sealing
It adopts hermetic head faces with high degree pottery and
corrosion resistance for opening and closing. It combines with Service,
Backwash, and Fast Rinse.
No water pass the valvein rinsingin single tanktype
Manual function
Realize rinsing immediately by pressing “ ” 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 processwill continue to work after power on.
LED dynamic screen display
The stripe on dynamic screen flash, it indicates the control valve is
in service; otherwise, it is in rinsing cycle.
Buttons lock

MODEL F71B/F71G/F67C/F67G/N75A/N75B
4
No operations to buttons on the controller within 1 minute, button
lock indicator light on which represent buttons are locked. Before
operation，press and hold the “ ”and“ ” buttons for 5 seconds to
unlock. Thisfunction can avoid incorrect operation.
Rinsing frequency
It could set up multiple rinsing times, which means several times of
backwash and fast rinse but one time of service. It is much better for
cleaning the filter materials.
There are two kinds of time clock types
Time clock type valve can be chosen to be service by hours ,by
dialing the red switch on main control board to “1” (Refer to the Figure
3-1). Pointing to “ON” mean the time clock type service by days; “1”
means the time clock type service by hours.(Attention: after dialing the
switch, please restart the power)
Interlockfunction
It has a function of interlock to realize only one valve in rinsing, but
the other valves are in service while there are 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 rinsing to
ensure pass water all the times while different valves in
rinsing.(Application refer to Figure 3-10)
Signal output
There is a signal output connector on main control board. It is for
controlling external wiring ( Refer to Figure from Figure3-2 to Figure 3-9).
There are two kinds of output modes. b-01 Mode: Turn on start of
regeneration and shut off end of regeneration; b-02 Mode: Signal
available only intervals of rinsing cycles and In service.

MODEL F71B/F71G/F67C/F67G/N75A/N75B

b-01
b-02
Remote handling input
This connector can receive external signal, used together with PLC,
and computer etc. to control the valve. （Application refer to Figure3-12）
Pressure reliefoutput
The valve will cut off feeding water to drain line when it switches in
rinsing 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 rinsing too fast to damage the valve. Pressure
Relief Output can be used to avoid this problem. (Application refer to
Figure3-11).
All parameters can be modified
According to the water quality and usage, the parameters in the
processcan be adjusted.

1.5. Installation
A. Installation notice
Before installation, read all those instructions completely. Then
obtain all materials and tools needed for installation.
The installation of product, pipes and circuits should be
accomplished by professional to ensure the product can operate
normally.
Perform installation according to the relative pipeline regulations
and the specification of Water Inlet, Water Outlet, and Drain Outlet.
B. Device location
①The filter should be located closely to drain.
②Ensure the unit is installed in enough space for operating and
maintenance.
③The unit should be kept away the heater, and exposed outdoor.
Sunshine or rain will cause the system damage.
④Please avoid to install the system in one Acid/Alkaline, Magnetic or
strong vibration circumstance, because above factors will cause the
system disorder.
⑤Do not install the filter, drain pipeline in circumstance which
temperature may drop below 5℃, or above 50℃.
⑥One place is recommended to install the system which causes the
minimum loss in case of water leaking.
C. Pipeline connection (Taking F71B for example)
①Install control valve
a.As the figure1-1shows, select the relevant riser pipe, 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.

MODEL F71B/F71G/F67C/F67G/N75A/N75B
10
b.Fill the mineral to the tank, and the height is accordance with the
design code.
c.Remove the tap covering on the central tube and check if the riser tube
is on the central of tank.
d.Install the top distributor to the valve and insert the riser tube into
control valve and screw tight controlvalve.
Note：
●The length of riser tube should be neither higher 1mm nor lower 5mm
tank top opening height, and its top end should be rounded to avoid
damage of O-ring inside the valve.
●Avoid floccules substance together with filter materials fill in the tank.
●Avoid O-ring inside control valve falling out while rotating it on the tank

MODEL F71B/F71G/F67C/F67G/N75A/N75B
11
②Pipeline connection
a. As figure 1-2 shows, install a pressure gauge in water inlet.
b. Install valve A, valve B, valve C and valve D in the inlet and outlet
pipeline. The valve D is sampling valve.
c. Install the checkvalve in the outlet pipeline.
d. Inlet pipeline should be in parallel with outlet pipeline. Support inlet
and outlet pipeline with fixed holder.
Note:
●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.

MODEL F71B/F71G/F67C/F67G/N75A/N75B
12
③Install drain pipeline
Directly connect the drain with the rigid pipeline, such as UPVC, etc.
Note:
●Control valve should be higher than drain outlet, and be better not far
from the drain hose.
● Be sure not connect drain with sewer, and leave a certain space
between them (As the figure 1-3 shows), avoid waste water be absorbing
to the water treatment equipment.
●If waste water is used for other purpose, please use another container
for loading.And also keep a certain space between drain and container.
