General Product Information
The central whole house water filtration system utilizes high-quality KDF55, and coconut shell
activated carbon to purify municipal tap water, effectively reducing odor, residual chlorine, and
organic content.
The automatic backflush system is designed to flush and wash the filter media and move pollutants
to the drain. The whole house central water filtration series carries excellent effluent water quality
and abundant water purification flow, making the facility's water safe for use. The resulting purified
water meets users' drinking and bathing requirements, including families, enterprises, and institutions.
There are three main working stages for this system, as shown below:
1) Service: After the machine filters the municipal pipeline water, it can provide drinking water
per specifications.
2) Backwash: Backwash can remove the impurities remaining in the upper layer of the filter
material and the toxic and harmful substances adsorbed in the filter material, restore the
performance of the filter material, extend the life of the filter material, and prevent filter media
from re-entering the water and compromising the water quality.
3) Purge/Rinse: Rinse the filter material, drain the dirty water, and fill the machine with filtered,
purified water, compact the filter material, and keep the filter material always operating in high
quality to best prepare for the next water purification cycle.
The main functions of this system are listed below.
•Fully Automatic Control
•A built-in time controller, twenty-four-hour time control. Based on the set number of interval
days or the amount of treated water, the filter material is cleaned at the set regeneration time
(usually in the early morning before any use).
•The regeneration cycle can be set based on time or treated water volume.
•Users can arbitrarily set the start time of the regeneration process.
Notice
Warning
◼This system can only be used with 120V/60Hz unidirectional AC power.
◼Do not place objects on top of the power cord, and set the unit in an area where the power cord
will not be stepped on or tripped over.
◼Electric shock hazard: Do not overload sockets or extension cords.
◼If there is smoke, abnormal odor, or abnormal noise coming from the machine, immediately
unplug the system's power to avoid fire or electric shock.
◼Do not touch the plug with wet hands to prevent electric shock.

may cause the threads to slip and the screw to crack.
Installation Instructions
(1) General Bypass

www.123filter.com | [phone] | [e-mail] Page 9
a. Hold the knob or use a bypass tool to rotate the knobs. The water supply will be bypassed when
the knobs are horizontal. The bypass valve is in service when knobs are oriented vertically.
When the bypass valve is in service, users can take raw water and filter water samples for testing
at the water-taking port on either side of the bypass.
b. In case of equipment failure or other exceptional circumstances, the bypass can be adjusted to the
bypass position, allowing users to use tap water temporarily. After the failure or problem is
resolved, adjust the bypass to the vertical service position.
(2) Before Installation
•Verify the water source pressure; the acceptable range is 35 psi - 100 psi. If the pressure is higher
or lower than this, it is recommended to install a pressure stabilizer.
•Do not remove the clips when the system is in operation; relieve the pressure before removing the
clips.
(3) Equipment Installation
It is highly recommended that you watch the video Installation & Startup | iSpring WF150K Whole
House Water Filtration System | Step by Step on YouTube.
Step 1. Confirm proper installation conditions, unpack the equipment and verify that all accessories are
present. Prepare the installation tools and confirm that the installation site's water inlet and outlet
pipes, power supplies, drain tube, and floor drain meet the appropriate requirements.
Step 2. Lubricate the inlet/outlet connect screw o-ring and tank o-ring seal. Install the main control
valve on to the system body. Use only food grade/included silicone lubricant.
Step 3. Close the main water supply completely, then open any faucets in the room to remove the
remaining water in the indoor water pipe.
Step 4. Connect the water inlet and outlet pipes of the system to the pipeline.
Double check the direction of the water flow matches the sign on the system. Pay attention to the
pipeline's height and placement angle when connected to prevent the connection pipes from bearing
stress. While connecting pipes, keep the pipes as close to the wall as possible. The routing of the
pipes should be straight, and the corners should be clear. The pipes should be fixed on the wall after
installation.

Page 10 www.123filter.com | [phone] | [e-mail]
Step 5. Connect the drain hose and clamp to the system tightly to ensure a secure connection.The other
end of the drain hose goes to the sewage pipe.
There must be sufficient space (~10 cm) between the outlet of the drain hose and the sewage level to
prevent sewage from flowing back to the product. The sewage pipe should be 30 cm higher than the
ground, and the drain hose should be fixed on the sewage pipe.
Step 6. Plug in the power adapter and connectthe other end of the socket to supply power to the system.
Step 7. Rotate the bypass valve knobs to the bypass position.
Step 8. Slowly turn on the main water supply.
Step 9. Open a cold water tap nearby and let the water run for a few minutes till the water runs clean
or until the system is free of foreign material caused by plumbing work. Then close the tap.
Step 10. Then, slowly open the water inlet knob on the bypass valve (the valve should be opened at an
angle of about 45°). Start regeneration and wait for the "BACKWASH" text on display to stop
flashing and start to count down, then unplug thepowersupply, and keep the device in the backwash

Operation Tips
•The product can be generally used after installation and commissioning have been completed.
With an uninterrupted power supply, the user does not need to perform other operations on the
machine.
•The automatic regeneration start time default is to start late at night. The water is not treated and
should not be used during this time.
•During the use of the system, do not cut off the power to avoid errors in the clock on the system,
which will affect the original regeneration start time and lead to the potential use of untreated
water.
•When the water supply is shut down, the system should be in the bypass position. When the water
supply is restored, the faucet in the home should be opened first. When the watersupply is restored
after the water supply is shut down, pollutants in the water pipe may enter the system and damage
the machine, leading to filter failure. The contaminated water should be released, and the system
should return to the service position after the water runs clear.
•DO NOT regenerate any other softeners/filters at the same time as this system since this will
interfere with the regeneration process and cause damage.

•If the equipment fails or experiences other exceptional circumstances, the inlet and outlet valves
can be closed (the bypass valve is open), and the municipal water supply can be used directly.
After removal, open the water inlet and outlet valves of the device.
•During regular use of the bypass, do not pull out the clamp. The pressure must be released before
the clamp is removed.
Emergency Response
•If the equipment fails or experiences other exceptional circumstances, the inlet and outlet valves
can be closed (bypass position), and the municipal water supply can be used directly. Reopen the
system's water inlet and outlet valves once the emergency is fixed.
•If water consumption increases significantly (compared to normal usage) or the quality of raw
water decreases, the number of regenerations should be increased accordingly.
•During the process of system regeneration, if the system experiences a power loss, more than one
discharge may occur, resulting in the waste of water resources.
•In case of power failure, readjust the current time and regeneration start time according to the
manual after the power supply is restored.
•When the water supply in a residential area is shut down, the main water main valve should be
closed immediately. The municipal water supply may cause negative pressure on the household
pipeline and damage the equipment.
