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 filter should be adjusted accordingly.
Test water periodically to 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.
We advise you to use M88×2 distributors for N56D top-mounted. It is
easy for disassembly.

1.5. Installation
A. Installation
Before installation, read all those instructions completely. Then obtain
all materials and tools needed for installation
The installation of product, pipes, 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, Drain Outlet.
B. Device location
①The filter should be located close to drain.
②Ensure the unit is installed in enough space for operating and
maintenance.
③The unit should be kept away the heater, and not be exposed outdoor.
Sunshine or rain will cause the system damage.
④Do not install the filter or softener, drain pipeline in circumstance which
temperature may drop below 5℃, or above 50℃.
⑤One place is recommended to install the system which cause the
minimum loss in case of water leaking.
C. Pipeline installation（Taking F56A for example）
①Install control valve
a. As the Figure 1-1 shows, select the riser pipe with 26.7mm 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.
b. Fill the filter material 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 control valve

Note:
●The length of riser tube should be neither higher 2mm 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 resin to fill in the tank.
●Avoid O-ring inside control valve falling out while rotating it on the tank
Pipeline connection
a.As Figure1-2 shows, install a pressure gauge in water inlet.
b.Install valve A, valve B, valve C and valve D in inlet pipeline, outlet
pipeline, the middle of the inlet and outlet pipeline. valve D is sampling
valve.
c. Install a check valve in water outlet
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.
