Operating Conditions
This softening system will operate at maximum efciency under the following conditions:
Operating Conditions
Working conditions Working pressure 21 psi to 120 psi
Water temperature 40°F - 120°F (5° C - 50°C)
Working Environment
Environment temperature 40°F - 120°F (5°C - 50°C)
Relative humidity ≤95% when temperature is 25C/77°F
Power source AC100~240V/50~60Hz
Inlet Water Quality
Water turbidity Down-ow Regeneration <5FTU
Chlorine <0.1ppm
Iron2 <0.3ppm
• All plumbing and electrical work should be performed by an accredited professional to ensure all local, munici-
pal, and state codes are met.
• Do not use the water softener with water that is unsafe or of unknown quality.
• Do not use the brine tube, injector body, or other connectors on the valve as a handle to carry the system.
• Ensure there is salt in the brine tank at all times when in use for softening. The brine tank should contain clean
water softening salt only, at least 99.5% pure. Do not use small grain salt.
• When there is moderate to high turbidity, a lter should be installed before the softening system on the inlet
side.
• If the water pressure exceeds 80 psi, it is recommended to install a pressure valve. If the water pressure is under
20 psi, a boost pump must be installed before the water inlet.

Prior to Assembly
IMPORTANT NOTE: To avoid irreversible
damage to connector threading, hand tighten
plastic connections rst. If leaks are noted
during initial start up, gently tighten with tool.
1. Prior to installation of this water softener, ensure you are aware of local laws and
codes regarding the installation, use, and maintenance of water softeners.
2. Resin Tank - the tank may be shipped with a temporary shipping cap, a master
O-Ring, and a piece of tape covering the riser tube. This is to prevent resin from
entering the riser tube during shipping. The cap, master O-Ring, and tape must
be removed and discarded prior to attaching control valve and the upper distrib-
utor. (Another master O-ring is supplied.)
3. Unpack the Tier1 WS-165-150-BLK and ensure all listed parts are included.
4. Turn off the main water line to your home prior to installation.
5. If you will be draining the tank, shut off the power supply to your water heater.
6. Turn on the water faucets in the highest and lowest levels of your home.
Begin assembly on pages 7-12.

Programming
After Control Valve has been programmed, perform the following steps before rst use:
Open a water line and let water ow until water runs clear.
Press and hold both up and down keys simultaneously for 3 seconds to unlock the key pad.
Press Regen key to advance through each cycle, following the below instructions.
When you press the Regen key, the screen will display “motor running” as it positions the ceramic disc. Once
“motor running” disappears and the next phase is displayed, press manual return key to advance to the next phrase.
1 - Backwash - lets air out of the drain line. Process will take 8-10 minutes to purge the system.
Press Regen key to advance to the next phase, brine and slow rinse.
2 - Brine and slow rinse - verify the air check valve is closed by listening to be sure no air is being drawn into the
system. Press Regen key to advance to the next phase, brine rell.
3 - Brine rell - This stage will ll the brine tank with the correct amount of water. Allow the brine rell phase to
run, do not advance past this phase until it is complete. After this phase has completed, press Regen key to advance
to Fast rinse, then press Regen key again to return to In Service position.
Add salt to the brine tank (40 pound minimum, 120 pound maximum).
Note: We recommend using water softener salt, 99% pure.
Install brine tank cover.
Turn on a faucet away from the installation location. Turn off faucet when plumbing lines have been purged.
Your water softener should now be fully operational.
To verify that your water softener is functioning correctly, take a water sample test to verify hardness reduction.
Manual Regeneration
To force a manual regeneration:
Press and hold up and down keys for ve seconds until a beep sounds and the button lock indicator light
turns off.
Press Regen key to start the backwash.
Press Regen key again to move to Brine and Slow Rinse (60 minutes)
Press Regen key again to move to Brine Rell (13 minutes)
Press Regen key again to move to Fast rinse (10 minutes)
Press Regen key again to return to In-Service.

Bypass Valve Information
Automatic Bypass Information
The automatic bypass is controlled by the settings
chosen on the control valve.
The keys on the bypass valve serve no function when
connected to the control valve and should not be used.
Bypass stages
The bypass stage used by the automatic bypass is
determined by the water hardness setting selected during
programming of the control valve.
Bypassing Stage III - water hardness 200-300 mg/L
Bypassing Stage II - water hardness 301-425 mg/L
Bypassing Stage I - water hardness 426-550 mg/L
Turning O Bypass
The control valve controls the bypass settings. To change the bypass settings, press and hold both up and
down keys simultaneously for 3 seconds to unlock the key pad.
Press Menu key. Display shows “Set Soener Para.”
“Set Time of Day” is selected automatically.
Press Down key until can select “Bypass set” as shown in Fig. 3A.
Bypass is set to Intelligent Bypass during normal service as shown in Fig. 3B.
If you do not want unsoftened water to be able to ow during your
softener’s regeneration, press Down key to select “No bypass”.
If you want to allow water to fully bypass the water softener, press Down key to
select “Fully Bypass.”

Care and Maintenance
Bridging
Humidity or the wrong type of salt may create a cavity between the water and the salt. This action, known as
“bridging”, prevents the brine solution from being made, preventing the water softener from working.
If you suspect salt bridging, carefully pound on the outside of the plastic brine tank, or pour some warm water over
the salt to break up the bridge. This should always be followed by allowing the unit to use up any remaining salt, and
then thoroughly cleaning out the brine tank. Allow four hours to produce a brine solution, then manually regenerate
the softener.
Caution
Liquid brine will irritate eyes, skin, and open wounds. Gently wash exposed areas with fresh water. Keep children
away from water softener.
Product Care
To retain the attractive appearance of your new softener, clean occasionally with a mild soap solution. Do not
use abrasive cleaners, ammonia, or solvents. Never subject your softener to freezing or to temperatures above 43
degrees Celsius (110 degrees Fahrenheit).
Effective water softener maintenance is critical to ensuring your system operates efciently. The Tier1 water
softener cleanser is packaged in a 16 ounce bottle, simply pour the entire bottle into the brine well every four
months. The cleanser will eliminate contaminants and build up that are not removed during a backwash cycle or
regeneration phase. Purchase at tier1water.com/ws-clnsr-16.
