II. Installation Safety Guide
IMPORTANT! The following conditions for feed water supply must be met or warranty will be
void and the manufacturer assumes no responsibility for damage to system or property.
1. Water Temperature Parameter
The system MUST NOT be installed in an area where it is exposed to direct sunlight and must
be protected against freezing and extreme heat.
• Maximum: 100° F (37.8° C)
• Minimum: 32° F (0° C)
2. Water Pressure Parameter
The maximum allowable inlet water pressure is 125 psi. If daytime pressure is over 80 psi,
night time pressure may exceed the maximum allowed water pressure. Use a pressure
reducing valve (PRV) to reduce the pressure if needed.
• Maximum: 125 PSI (8.78 kg/cm2)
• Minimum: 25 PSI (1.75 kg/cm2)
3. Chlorine & Chloramine Tolerance
Softener resin may degrade in the presence of chlorine or chloramines. Feedwater that
contains these contaminants will reduce the life of the resin. In these conditions, a whole
house carbon ltration system with chlorine, chloramine reducing media is recommended.
• Maximum: 2 ppm
4. Pre-install environment checklist
• Not for use with microbiologically unsafe water. Pre-ltration to remove contaminants
and heavy sediment recommended to ensure optimum performance and product life.
• Properly ground to conform with all governing codes and ordinances. Use only lead-free
solder and ux for all sweat-solder connections as required by state and federal codes.
• Place softener as close as possible to the pressure tank (well system) / water meter (city water).
• Place softener as close as possible to a oor drain, or other acceptable drain point
(laundry tub, sump, standpipe, etc.) to prevent air breaks and back ow.
• Place softener in a place where water damage is least likely to occur if a leak develops.
• The brine tank should be located no more than 10’ from the resin tank.
• Connect the softener to the main water supply before the water heater. Do not run hot
water through the softener. Maximum temperature of softener water is 100º F.
• Outside faucets and irrigation systems should be supplied with pre-softened water. If this
is not possible, be sure to bypass the softener when watering grass or plants. Chronic soft
water exposure can be detrimental to plant life.
WARNING! For your safety, the information in this manual must be followed to minimize the
risk of electric shock, property damage or personal injury.

5www.AQUASUREUSA.com Tel: [phone]
4. Pre-install environment checklist (Continued)
• A 120 volt electric outlet must be within 6 feet of the softener. The transformer has an
included 8 foot power cable. Be sure the electric outlet and transformer are protected
from water and wet weather.
• If installing outside, necessary steps must be taken to ensure the softener, installation
plumbing, wiring, etc. are protected from the elements and contamination sources.
• Handle with care when moving the water softening system. Do not drop, drag, or set on
areas with sharp protrusions.
• The system works on standard 110v power plug only. Do not use any other transformer
except the one that is included with the system.
• Transformer must be plugged into an indoor 120 volt, grounded outlet.
• Use only clean water softening salt with at least 99.5% purity. Extra course grade or
crystal salt is recommended. Do not use rock, block or granulated salts. These contain
contaminants that could cause problems during maintenance.
• Always keep salt lid in place on the softener unless servicing or relling the unit.
• Some applications may not have a level surface to place the tank. The oating base allows
the tank to be leveled within the base and ensures proper operation.

III. Installation Diagram
The following diagram displays how the water softener should be installed with a well or city water
setup. If you have city water, your plumbing arrangement will vary but the installation principles are
the same. This is an example of how a pre-lter, media tank and water softener ow in line together.
If you do not have a media tank/ carbon lter with your purchase, then exclude it from your
installation. A loop installation with shut-off valves is advised as seen below.

7www.AQUASUREUSA.com Tel: [phone]
IMPORTANT! Locate and test the main water supply valve to the home before installing the
system. If the main water supply valve fails to shut off the water completely during the test, we
recommend contacting your local plumber to x the valve before installing the system.
STEP 1. Shut off the Main Water Supply Valve
1. Locate the main water supply valve of the house and turn off completely by turning the
shut-off handle clockwise.
2. Test to see if the water is completely shut off by turning on the closest faucet in the cold
water position. If the cold water cannot be shut off, please contact your local plumber to
x the valve before begin installing the system.

STEP 2. Mounting the Control Valve
2. Make sure the o-rings are lubricated before
installing. Lubricate both O-rings on the bottom
of the control valve (inner and outer).
1. Attach the bypass valve onto the control head
and secure it with the metal plates. Make sure
the o-rings are lubricated before connecting.
(Silicone Grease recommended as lubricant.)
5. Place the upper basket over the distributor tube
and push the valve on the tank. Thread the valve
on the tank by turning it clockwise. Be sure not
to cross-thread the valve on the tank. The valve
should thread easily in the tank. If not, it may be
cross-threaded.
DO NOT LUBRICATE as you may over-tighten
the valve.
3. Lubricate the riser tube located on the opening
of the tank. Make sure riser tube is ush with
the top of the tank.
6. Tighten the valve hand tight, then snug it
further by tapping it with the palm of the hand.
DO NOT use tools to tighten the valve or
damage could occur.
4. Install the upper basket on the bottom of the
valve by lining up the tabs, pressing in, then
turning the basket counterclockwise to lock it in
place.

9www.AQUASUREUSA.com Tel: [phone]
STEP 3. Connecting the Softener
IMPORTANT! On copper plumbing systems, be sure to install a grounding wire between
the inlet and outlet piping to maintain grounding.
WARNING! Any solder joints being soldered near the valve must be done before
connecting any piping to the valve. Always leave at least 6” (152 mm) between the
control valve and joints being soldered when soldering pipes that are connected to the
valve. Failure to do this could cause damage to the valve.
1. The control valve is equipped with 1” male NPT
connections. It is recommended that these
connections are made using 8-12 wraps of
plumber’s tape.
2. The inlet and outlet can be identied by the
arrows stamped in the bypass valve showing the
ow direction. The arrow pointing toward the
valve is the inlet and the arrow pointing away from
the valve is the outlet.
3. Apply the plumber’s tape onto the bypass inlet and
outlet ttings.
4. Connect the inlet and outlet of the softener using
appropriate ttings.
5. All piping should be secured to prevent stress on
the bypass valve and connectors.
6. Connect the drain hose to the valve by removing
the orange lock clip and push the 1/2” black tubing
into the hole. Secure the line by pushing the
locking clip back in.
7. Pull the drain line to see if it is secure. Run the drain
hose to the nearest laundry tub or oor drain. This
can be run a max of 7 ft overhead or down along
the oor. Drain hose should be a minimum of 1/2”.
If running the drain line more than 20 ft linear, it is
recommended to increase the hose size to 3/4” and
be sure there are no sags or “drops” in the hose on
the way to the drain destination.
Note:
A direct connection into a waste drain is not
recommended. A physical air gap of at least 1.5”
should be used to avoid bacteria and wastewater
traveling back through the drain line into the softener.

10
AQUASURE HARMONY SERIES
2. Push the brine line into the brine
line connector and make sure it goes
through the o-ring. Secure by pushing
in the locking clip. Pull the brine line to
see if it is secure.
1. Connect the brine line to the control
valve by removing the blue locking clip
on the brine line connector.
IMPORTANT! Make sure the brine line is secure to the connection provided on the brine tank. If
the brine line is not secure and sealed, it may not be able to perform a proper system regeneration
when needed, and can potentially cause overll in the brine tank and result in leaks.
STEP 4. Connecting the Brine Tank
3. Your brine tank system is 90% pre-assembled. To
nish the setup, unscrew and remove the black nut
on the connection protruding from the brine well.
4. Rotate the brine well and insert the connection
through the upper hole in the brine tank.
5. Re-screw the black nut onto the connection on the
outside of the brine tank so that it is snug.
6. Please ensure that your brine hose is thoroughly
connected at the brine tank tting. The hose
should be fully seated into both ends of the quick
connection.
7. Pour in 80 lbs (two bags) of course grade salt and
5 gallons of tap water into the brine tank.

Optional Brine Tank Overll Connection:
Below the brine hose connection you will notice a 90-degree barbed connection facing
downward. This connection is optional since the brine well is equipped with an automatic
oat valve shutoff.
If you still want to utilize the overll connection, lubricate the barbed connection with
silicone grease or any food-grade oil. You will need to purchase an additional ½” plumbing
hose and place the hose onto the connection for a secure seal. Typically, the other end of
the hose will feed off into a oor drain, laundry style sink, or dedicated drain connection.

1. Place the unit in the bypass position. Locate the nearest faucet and remove aerator
(faucet screen) if there is any. Turn the cold water position on at the nearest faucet and
slowly turn on the main water supply. Let the water run for a few minutes or until the
system is free of any air or foreign material.
2. Make sure there are no leaks in the plumbing system before proceeding and shut off the
nearest faucet when water runs clear.

WARNING! DO NOT UNPLUG THE UNIT’S POWER SUPPLY DURING REGENERATION!
SYSTEM INITIALIZATION
Note:
Make sure the system is powered on before starting. Plug the power transformer into an approved
power source. Connect the power cord to the control valve head and before continuing ensure that 5
gallons of water and at least 80 lbs of salt have been added to the brine tank.

14
AQUASURE HARMONY SERIES
STEP 2. System Startup
1. When power is supplied to the control, the screen will display the time of day, gallons
remaining and the regeneration mode. Press and hold the “Cycle” button for 5 seconds
until you see the words “goto bW” and then release the “Cycle” button. The backwash
(bW) will be underway.
2. Once the valve is in the backwash (bW) cycle, you will see the 15-minute (015) countdown
next to “bW”. Open the inlet on the bypass valve slowly and allow water to enter the unit. If
you hear any large “knocking” sounds, turn the red inlet valve partially closed (not all the
way) as the water is being fed too quickly and should be slowed. This process will begin to
purge air from the resin tank and ll the resin tank with water, allowing the air to escape
to the drain line. The water to the drain line will eventually start to run clear after 3-4
minutes.
3. After the backwash you will see the system move into the brine draw (bd). The brine draw
is 60 minutes total and will normally draw out the saltwater within 20-30 minutes leaving
the rest of the time for the saltwater to bond with the resin. After the BD the rapid rinse
(rr) will start for a duration of 10 minutes. Allow the entire cycle to run so the resin is
rinsed clean.
4. When the rinse cycle is complete, the control screen will move on to the brine ll (bF).
This phase will ll water back into the brine tank. You should gradually start to see the
water level rise to half a tank full. Let the entire brine ll nish.
5. When the regeneration cycle is complete, open the outlet side of the bypass completely
allowing water to ow into your home. From this point, locate the nearest treated water
faucet. Remove the aerator screen and run the cold water until the water is completely
clear. Once done, shut off the faucet water and place the aerator screen back on the
faucet.
STEP 3. Programming the System
IMPORTANT! The settings are pre-programmed from the factory to work with the majority of
homes. We recommend programming the system from settings 1 - 4 and leave settings 5 - 8 at
system default unless the condition of water requires adjustment.
Enter Setting Menu by pushing both the ENTER button and UP button at the
same time. The screen will jump from the service screen with the faucet icon to
the rst setting screen to set time.
