Installation Guide

In order to fit differently-sized pipelines, three thread specifications (1’’MNPT, 3/4’’ FNPT, and 3/4’’ MNPT) and 3/4’’ Push-fit plumbing were applied to the inlet and outlet of the system, and a total of four installation methods were optional, which can be connected with PEX, CPVC, PPR and copper pipes. Please select the appropriate connection method according to the size of the pipe in your home. Pay attention to the water flow direction when installing. Taking the 3/4’’ MNPT thread specification and PEX pipe as an example:

Use 3/4” MNPT

1. Shut off the main inlet valve. Turn on the faucet to release the pressure inside the pipe.

2. Take out the 3/4’’ MNPT adapter, insert the threaded union into the union nut and install the white gasket. Install the assembled adaptor on both sides and tighten or with a wrench.

3. Wrap more than 10 loops of Teflon tape on the external thread of the union on the both sides. Install two 3/4 in. Brass PEX-A Barb x 3/4 in. FNPT Female Adapters (not included in the box) on the adapter, and tighten it with a wrench.

4. Cut off the appropriate length of PEX pipe. Fix the pipe on the system with two 3/4 in. Stainless-steel PEX Barb Pinch Clamps. Pay attention to the water inlet direction, and do not install it in the opposite direction. You can also use an expansion ring to fix the pipe.

5. Insert the drain tubing into the quick-connect threaded connector. Ensure that the tubing is inserted in place. You can lead the drain tubing to sewage outlets or a bucket.

NOTE: Please ensure the drain tubing is fully inserted and fixed to avoid sewage overflow.

6. Slowly turn on the main inlet valve. Turn off the water outlet after the domestic water equipment is able to dispense water seepage at the joints.

7. Open the battery case and install three batteries (AAA). When the power is turned on, the buzzer beeps once, and the three indicators flash blue three times. Then the sewage outlet is opened, and after 15 seconds, the sewage outlet is closed.

8. Set up flushing interval. By touching “Setting” button, you can choose 7,15 or 30 days as flushing interval period according to your household water quality. Corresponding indicator turns into blue after setting. The default flushing interval period is 15 days.

9. Touch “Flushing” button after setting and enter manual flushing state. Please flush the filter at least twice about 1 minute before firstly using.

Use 3/4” FNPT

a. Wrap at least 10 loops of Teflon tape on the 3/4” FNPT thread. Install two 3/4 in. Brass PEX-A Barb x 3/4 in. MNPT Male Adapters (not included in the box) on the adapter and tighten it with a wrench. 

Refer to the installation steps above for further steps.

b. Use Push-fit Plumbing

1. Ensure that the cut of the pipe is flat and surface is smooth. If there are many impurities on the surface of the pipe, it should be polished with sandpaper before installation.

2. Wrap at least 10 loops of Teflon tape on the Push-fit plumbing thread, then install it in system and tighten it with a wrench.

3. Insert the pipe directly into the Push-fit plumbing fitting, which must be fully inserted; otherwise, there is a risk of water leakage.

4. With the help of the deeper a depth gauge tool, the pipe can be marked first and then inserted into the Push-fit plumbing fitting according to the marked depth.

Use 1” MNPT

Wrap at least 10 loops of Teflon tape on the 1” MNPT thread. Install two 1 in. Brass PEX-A Barb x 1 in. FNPT Female Adapter (not included in the box) on the adapter and tighten it with a wrench.

Refer to the installation steps above for further steps.

NOTE: The external thread must be wrapped with at least 10 loops Teflon tape, and then connected to the internal thread and tightened with wrench.

Product Operation

Installation Position Schematic Diagram

Flushing Status

1. Automatic flushing When the set automatic flushing interval time is up, the filter starts draining sewage for 30 seconds. Meanwhile, the flushing interval period indicator flashes. Indicators are off when flushing is completed.

2. Manual flushing When the filtered is blocked, you can touch “Flushing” or “Setting” button to activate back-washing function immediately with buzzer beeping. Single back-washing lasts 30s and you can choose flushing times according to actual situation. The flushing interval is re-accumulated when it’s completed. During flushing, touch “Flushing” button and machine stops flushing with buzzer beeping.

3. Standby state and awake machine with no operation within 15s, indicators are off and machine is locked and on standby. You can awake the machine by touching either “Setting” or “Flushing” button with buzzer beeping.

Clean the Filter Mesh

When some sticky impurities are embedded in the filter mesh and cannot be discharged after the drain valve is turned on, which also affects the water output and pressure of the other equipment, the filter mesh should be flushed.

1. Shut off the main inlet valve. Turn on the drain valve to release the pressure inside the pipe.

2. Put the wrench on the transparent filter housing, and unscrew the filter bottle clockwise. It is recommended to use the container to catch the residual water in the filter housing. [Figure 1]

Figure 1

3. Take out the filter mesh and remove the impurities with a cleaning solution or brush. [Figure 2]

Figure 2

Note: Do not use a strong acid or alkaline cleaning solution.

4. Put the clean filter mesh back to the filter housing. [Figure 3]

Figure 3

5. Tighten the filter housing and machine head with a wrench.

6. Turn on the main inlet valve, and then check whether there is water leakage.

Direction for Use

1. After the installation, the user opens the water inlet valve and the filter starts to work normally. After the filter is working for a while, when the accumulated impurities looked through the transparent bucket have affected the water output of the household water equipment, the filter mesh can be cleaned.The flushing button at the bottom can be rotated to flush and discharge the filtered impurities.
2. When there are some sticky impurities accumulating on the filter mesh, or the impurities are embedded in the filter mesh, which cannot be cleaned by normal cleaning methods, and affects the water output and pressure of household water equipment, please contact Besdor after-sales service personnel for repair.
3. If there is any failure of the filter you purchased during use, do not disassemble the parts of the product in case of water leakage and damage to the product. Please turn off the water source, and then contact Besdor after-sales service personnel.
