Unpacking / Inspection 
Genesis Duo Quick Start Instructions
 
Be sure to check your entire water softener shipment for any possible damage that could have occurred in transit. You should have 
received a resin tank with resin inside and a temporary shipping cap on top. A brine tank assembled with a control valve box inside. 
Depending on what you added your order there may be additional parts or drain tubing included. If you feel there is an issue with your 
order, email us at sales@discountwatersofteners.com and someone will assist you right away. Your water softener control valve may 
have residual water inside from manufacturer QC check and the controller may show regeneration already performed by the controller 
and gallons registered as part of the manufacturer QC program. Small parts, needed to install the softener, are in a parts bag. To avoid 
loss of the small parts, keep them in the parts bag until you are ready to use them.
Upon startup of your control valve if the setting for the “Water Supply” is set to “Municipal” your control valve will not 
give you a backwash step. We suggest setting your water source to “Well/Other” until after startup is complete so you 
can do the initial backwashing of the resin. After the startup is complete you can change your water setting back to 
“Municipal” if your water source is municipal. 
Installation & Start Up
1.  Install unit as per local plumbing codes. (Refer to detail
  instructions in Owners Manual) Avoid pinched o-rings  
  during installation by applying (provided with install kit)
  NSF certified lubricant to all seals. Be sure to leave the  
  unit in the “BYPASS” position. Attach upper screen cone to  
  underside of control valve. 
2.   Connect the drain line to the valve.
3.   Connect the brine line from the valve to the air check / 
  safety elbow. Double check to make sure all connections
  are assembled correctly and the brass and plastic nuts are  
  tight and secure to prevent leaks. Be sure to install the  
  tube insert in the brine tubing before connecting the brine  
  tube to the control valve.
4.   Add at least 5 gallons of water to the brine tank. 
5.   Add at least 1 bag (about 40lbs of water softener salt) 
  to the brine tank.
6.   Plug the power transformer into an approved power
  source. Connect the power cord to the valve. When 
  power is supplied to the control, the screen may display  
  “INITIALIZING WAIT PLEASE” while it finds the 
  service position.
7.   Manually step the valve past the BRINE position to the
  BACKWASH position. If screen is locked, press SETTINGS
  for 3 seconds to unlock. Press and hold the MANUAL  
  REGEN. Key for 5 seconds. Press any key to skip the  
  BRINE cycle.
8.   Once in the BACKWASH cycle, open the inlet on the  
  bypass valve slowly and allow water to enter the unit.
  Allow all air to escape from the unit before turning the
  water on fully then allow water to run to drain for 3-4
  minutes or until all media fines are washed out of the
  softener indicated by clear water in the drain hose.
9.   Press any button to advance to the RINSE position. Check  
  the drain line flow. Allow the water to run for 10-15  
  minutes or until the water is clear.
10. Press any button to advance to the REFILL position. 
  Check that the valve is filling water into the brine tank.  
  Allow the valve to refill for the full amount of time as  
  displayed on the screen to insure a proper brine solution  
  for the next regeneration.
11. The valve will automatically advance to the SERVICE
  position. Open the outlet valve on the bypass, then open  
  the nearest treated water faucet and allow the water to  
  run until clear, close the tap and replace the faucet screen.
12. Program unit.
Programming Guide
Press the SET UP MENU key to enter the programming mode. 
Use the UP or DOWN key to adjust the value. Press SET UP 
MENU again to accept the value and advance to the next option.
SET HARDNESS
This value is the maximum compensated water
hardness in grains per gallon of the raw water
supply. It is used to calculate the system capacity. 
If Ferrous Iron is present add 5 gpg for every 1 
ppm of Ferrous Iron.
SET PEOPLE
This value is the number of people living in the
home. It is used to calculate the amount of water 
needed for daily use and the reserve capacity of 
the system.
SALT SETTING
Choose HIGH EFFICIENCY setting for your salt 
setting your system will utilize 3lbs of salt per 
cubic foot of resin. It is recommended you remove 
the salt grid in the brine tank for proper operation.
Choose STANDARD setting to maximize system 
capacity and utilize 6lbs of salt per cubic foot of 
resin. This is the recommended salt setting for 
your system. 
For Choose IRON & MN only one small change. 
Under "Note:” please change it to: A resin cleaner 
may also be needed to properly clean the resin 
when higher iron levels (3 to 5ppm) are present. 
WATER TYPE
If you are on clean city water choose the 
MUNICIPAL option so that the unit does not waste 
water performing a back wash every regeneration. 
If you are on well water or other choose WELL / 
OTHER to perform a back wash every 
regeneration.
After all installation and programming is 
complete, wait 6 hours and then perform a 
manual regeneration to get soft water.
