workplace. For the automatic product, it also needs the AC power receptacle.
※Generally, the products are installed in the equipment room, underground garage (These
places should have water inlet pipeline, water outlet pipeline, drain pipeline and sewage).Or they
can be connected with the main water inlet of the place, such as villas, apartments, schools or
business establishments, etc. If it is necessary, you can install the product outdoor. However, you
should take some protective measures to prevent the product from being frostbiting, basking and
water.
※Do not put the product near the place with alkaline and acid substance or gas, avoiding
being corroded.
※The suitable pressure for filter is between 0.15Mpa and 0.6Mpa. Booster pump or a relief
valve is necessary when the inlet pressure is lower or higher than standard.

5
※Make sure a check valve is equipped between the device and water heater when a heating
stove or water heater is connected behind the device, in case of hot water reflux and damage the
inner system of the product.
※Separate sewer line for the device is required. 5 to 10cm clearance must be maintained
between the drain pipe and floor drain, in case of siphon and cause valve damage by the waste
water.(Installation refer to below picture)
※Before installing the pipeline, please clean the residual impurity and dust in the pipeline.
After the main water inlet is closed, connect it with the device.
※All of pipeline that used should meet the relevant regulations, and the installation should
accord with the local installation rules.
※When install, please keep a certain operation space for adding salt, cleaning and
maintaining.
8.2Installation and Connection
※Pipeline installation and connection should conform to the local installation rules.
Inlet/outlet should be connected with the water pipe in the same axis (Refer to the below
installation picture). The position of inlet and outlet shouldn’t be reversed.
※It is suggested to install a manual bypass valve between the main water inlet and
inlet/outlet of the device, making it convenient for installation and maintenance. (Refer to the
below installation picture).

6
Illustration: Install two three-way ball valves to connect the control valve and inlet/outlet
pipeline. The valve B is connected with the inlet of the control valve; the valve Ais connected with
the outlet of the control valve. When repair the tank, adjust the valve A and B to make the inlet
connected with outlet directly, so the water do not pass through the valve; When normally use,
adjust the valeA and B connected with valve.
※Install the drain pipeline of water filter, use the PVC soft or hard tube.
1.Use PVC soft tube for installation
Take out the soft tube and metal clamp from the spare part kit, make the drain connector
insert into soft tube as much as possible, the insert part is no less than 20 mm (In winter, the
temperature is low, use the hot water to make the head of tube soft which is convenient for
installation.) After insert, put metal clamp on tube and tighten it by screwdriver. If it is not
convenient to assemble the tube on filter, it could remove the drain connector then assemble the
tube. Take out the clip before removing the drain connector (See following picture).
2.Use PVC hard tube for installation
When use PVC hard tube for installation, remove the connector and sealing ring as the
following picture. It needs professionals to install. The installation is like the following picture.

7
※Control valve should be higher than sewer. The length of drain line should be similar to the
height of tank. Insert the drain line to the floor drain, but not to the bottom. Leave about 5-10mm
distance between the end port of drain line and sewer.
※Each pipeline should be supported with fixed holder independently, avoiding the control valve
be damaged by bearing the gravity from the pipeline.
Notice: Please make sure the drain line and overflow line is connected and close to sewer,
making the waste water flow into the sewer rapidly.

After installing the device and setting the relevant parameters, please conduct the trial
running as follows:
Switch on power. Press and go in the Backwash status; adjust the bypass valve (Three-way
valve A and B) to service position, slowly open the inlet valve. At this moment, the air is emptying
from the drain pipeline. Until the drain water is clean.
Press , and turn into Fast Rinse status. Until the drain water is clean.
It needs couple times of backwash and fast rinse for the first time usage.
Press to back to Service status, open the faucet to check if the water is clean. If the water is
still carbon color, it needs more backwash and fast rinse.
Illustration: The purpose of frequently backwash and fast rinse for the first time of using the
system is to clean the carbon powder and activate it which is food grade. So there may be some
black water flowing out.
Notice:
If the water is entering fast, the media in tank will be loss. When water is entering slowly,
you can hear the sound of air-out from the drain pipeline
During the trial running, check each port, there should be no media flowing out. Check
each connection part, be sure there is no leakage.
The time of backwash and fast rinse is set depending on the practical need.
