Installation Instructions Cont’d
7. Place approximately 1” of water above the grid plate. If a grid is not utilized, fill to the top of the air check in the salt
tank. Do not add salt to the brine tank at this time.
8. On units with a bypass, place in BYPASS position. Turn on the main water supply. Open a cold soft water tap nearby
and let run a few minutes or until the system is free from foreign material (usually solder) that may have resulted from
the installation. Once clean, close the water tap.
9. Place the bypass in the SERVICE position and let water flow into the mineral tank. When water flow stops, slowly
open a cold water tap nearby and let run until the air the air is purged from the unit.
10. Plug unit into an electrical outlet. NOTE: all electrical connections must be connected according to local codes.
11. In normal operation the Time of Day and Volume Remaining is displayed. Set the Time of Day by:
• Press and hold the Up or Down button for 2 seconds.
• Press the Shift button to select the digit you want to modify.
• Press the Up or Down buttons to adjust the value.
• Press the Extra Cycle button to return to the normal display screen, or after a 5 second timeout.
NOTE: The “D” button (Diagnostic) can be pressed to exit without saving.
12. The Volume Remaining Display is the volume of water (in US gallons) remaining prior to regeneration, including any
reserve capacity. Without any water usage, the Flow Indicator (line) will be motionless. Open a soft water tap. A
rotating line (appearing as a rotating star shape) will display on the screen when flow is going through the the meter.
Close the tap after 3-5 gallons of water flow.
13. Initiate a manual regeneration cycle by pressing and holding the extra cycle button for 5 seconds. The piston will
move to the 1st cycle which is BRINE SLOW RINSE. Press the Extra Cycle button again and the piston will advance
to the 2nd cycle which is BACKWASH. Allow the water to run to drain for 3-4 minutes to purge the air out of the tank.
Press the Extra Cycle button again and the piston will advance to the 3rd cycle which is RAPID RINSE. Press the
extra cycle button again and the piston will advance to the 4th cycle which is BRINE REFILL. Press the extra cycle
button again and the piston will advance to the SERVICE position.
14. Add water to the brine tank to the top of the air check. Manually step the valve to the BRINE/RINSE position (see Step
13) and allow the valve to draw water from the brine until it stops.
Note: the air check will check at approximately the midpoint of the screened intake area.
15. Manually step the valve back to the SERVICE position.
16. With the valve in service, check that there is about 1” of water above the grid in the brine tank, if used.
17. Fill the brine tank with salt.
(Installation Tip: The 6700XTR Softener should not be allowed to regenerate at the same time as any other water
treatment units. If adjustment is required, consult programming chart to adjust default regeneration time.)
Optional Sanitization Procedure: We recommend that all new water conditioners be disinfected as part of the startup.
Sanitization is achieved by the application of chlorine in the regeneration cycle of the conditioner. A liquid solution of
5.25% sodium hypochlorite (commonly referred to as household bleach) is recommended as a suitable disinfectant. Use
only unscented products. For every cubic foot of resin in the softener, pour approximately two (2) tablespoons of sodium
hypochlorite into the brine well tube. Press and hold the EXTRA CYCLE button and allow the brine tank to fill with the
standard amount of water. Press the EXTRA CYCLE button again twice to advance the valve to the Brine/Rinse position.
Allow softener to complete the Brine/Rinse cycle, then press EXTRA CYCLE button three times to advance valve back to
service position.
