Parts required (Not Included)
(2x) Hex nipples or pipe nipples (2x) Shuto valves (as needed)
(2x) Pipe union pressure regulators (as needed)
Pre-installation
• Turn o the water to your house before beginning the installation. Turn o power
to your water heater before installation. Open all plumbing xtures in the house to
drain the lines of water and pressure.
• Lay out all the ttings and tools you will need to install the system depending on
your conguration. Be sure to use Teon tape on threaded ttings.
• Measure, cut, and remove the section of water line where the system is to be
installed. When determining the length of pipe to cut, account for lter width, shuto
valves, union ttings, nipple ttings, pressure gauges (if used) and bypass valve (if used).
• Allow the cut line to drain. Smooth the newly cut ends down to avoid jagged
points or edges.
• A three-valve bypass valve and loop may be installed to loop the entire system to
make servicing easier.
• The lter should be placed on the main water supply line near where it enters the
house at any point past the main shuto valve for the whole house, but before pipes
branch o into multiple directions. However, you may choose to locate the lter after
the line branches to the inside and outside plumbing depending on your ltration
intent. Your lter should be located in a dry, level area and protected from freezing
temperatures and direct sunlight.
Installation
Step 1: Select connection method according to pipe’s size
Please select the appropriate connection method according to the size of the pipe in
your home. Please pay attention to the direction of water ow when installing. Take
the 1” MNPT thread specication and 1” PEX pipe as an example:

Step 2: Measure the system and cut the pipe (Figure 3)
Determine location and water ow direction for the system. Cut o the appropriate
length of PEX pipe. Fix the pipe on the system with two 1’’. 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 x the pipe.
Step 3: Fix the whole house lter (Figure 4)
Securely mount the whole house lter bracket and ensure the system is level.
Notice: Fit pipe hanger (not included) on water INLET and OUTLET side for addition-
al support.

Step 4: Screw the lter housing tightly
Tighten the blue lter housing by hand. Then, use supply lter wrench to tighten the
blue lter housing.
Step 5: Slowly turn on the main inlet valve. Turn o the water outlet after the
domestic water equipment is able to dispense water. Be sure to check whether there
is water leakage or slow water seepage at the joints.
Caution: Do not use a hot water faucet to perform the initial system ush.
Notice: The water will be blackish in color for the initial ush. This is residual carbon
dust and is to be expected. Continue to run water until it runs clear and all air has
been purged. Shut the water o and let the unit sit for a while, and then ush again. It is
not unusual for the water to appear "cloudy" for a day or so following installation. This
cloudiness is actually tiny air bubbles being purged from the lters. This is normal and
will clear up in a day or two.
After prolonged periods of nonuse (such as a vacation), it is recommended that the
system be ushed thoroughly for at least 10 minutes before using the water.

Maintenance Instructions
Your Whole House Water System requires care and cleaning after a period of time. It is
recommended that the cartridges be replaced every 6 months depending on the
amount of contaminants present in the water supply. If the system has been working
properly and the pressure is slowing, it may be time to change the lter cartridge.
Filter Change Instructions
Step 1: Remove the old cartridge
1. Turn o the water supply to the system. Open a nearby faucet to release the
pressure and drain the water.
2. Depress the pressure release button on the top of the lter housing to relieve
system pressure. This will make removing the lter housing easier.
3. Unscrew the housing using the lter wrench included with your system.
4. Remove and discard the old lter cartridge.
Step 2: Clean the housings
1. Scrub the housing and cap with warm water mixed with about 2 tablespoons of
household bleach using a sponge or soft rag. Wear rubber gloves. Rinse all parts very
thoroughly!
2. Lubricate the O-ring with clean silicone grease if needed. DO NOT USE PETROLEUM
JELLY. Insert the O-ring in lter groove and press into place. Make sure the O-ring is
seated correctly.
Caution: This step is important to ensure the proper lter seal. Make sure the
O-rings are seated level in the groove. If the O-ring appears damaged, stretched, or
crimped, it should be replaced.
Step 3: Install the new cartridge
1.Remove the new lter packaging and insert the lter cartridges into the housings,
making sure they slip over the standpipe in the bottom of the housing.
2.Align the bottom of the housing into the cap and hand tighten, then use the lter
wrench to t it snugly. Do not over-tighten.
3.Close any open valves. Turn on the water supply slowly to allow the system to ll
with water. Inspect carefully for leaks. If a leak is found, remove the housing and
inspect the O-ring to ensure that it is seated properly, and then retighten.

Note: If there is a sealing ring left by the old lter element in the lter bottle, please
take out the sealing ring and put it in the lter element.
Step 4: Flush the system
Flush the system by turning on a few cold-water faucets. Allow the water to run until
the air and carbon has been purged. Water may be cloudy initially as the lters and
system clear of trapped air. New activated carbon lter cartridges may contain loose
carbon and air bubbles after installation.
Frequently Asked Questions
Q: Why does water leak from the housing connection?
A:
The O-ring may not be in place or not enough teon tape on the threads. Reapply
teon tape and tighten. If it still leaks after adjusting the O-ring or threads, please
contact us.
Q: Why does water leak from the pressure release button?
A:
The pressure release button has a screw under the bracket. Simply tighten that
screw and the leaking should stop.
Q: Why does water appear cloudy and gray?
A:
Water may appear cloudy or gray for the rst 1-2 days after installation due to the
tiny air bubbles being purged from the ters and extra carbon dust in the water.
Q: Why does water pressure slow after a period of time?
A:
It is recommended that the cartridges be replaced every 3-6 months depending
on the amount of contaminants present in the water supply. If the system has been
working properly and the pressure is slowing, it may be time to change the lter
cartridge.
Q: Why does water pressure slow immediately after installation?
A: The cartridges may be installed incorrectly. Check to see if a piece of the plastic
wrapping is still protecting the lter cartridges. Bathtubs, utility sinks, hose bibs,
multi-headed showers,body sprayers, or anything that is considered high-fow should
be avoided for the rst 72 hours. Any high-fow situation within the rst 72 hours may
cause a temporary carbon blockage. To clear the blockage, turn of any running water
for at least 10 minutes and resume using water at low or normal fow rates.
Step 2: Measure the system and cut the pipe (Figure 3)
Determine location and water ow direction for the system. Cut o the appropriate
length of PEX pipe. Fix the pipe on the system with two 1’’. 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 x the pipe.
Step 3: Fix the whole house lter (Figure 4)
Securely mount the whole house lter bracket and ensure the system is level.
Notice: Fit pipe hanger (not included) on water INLET and OUTLET side for addition-
al support.
