Installation Instructions Cont’d
4. Attach the bypass valve to the control valve. Connect the inlet and outlet of the water softener to the plumbing in the
house. The control valve must not be submitted to temperatures above 43°C (110°F). When sweat fittings are used, to
avoid damaging the control valve, solder the threaded copper adapters to the copper pipe and then, using Teflon tape,
screw the assembly into the bypass valve.
CAUTION - do not use pipe thread compound as it may attack the material in the valve body.
5. Using teflon tape, screw the 1/2” hose barb into the drain port in the valve. Attach 1/2” drain hose to the hose barb
and tighten securely with a hose clamp. Run the drain line to a floor drain or a laundry drain. Complete any necessary
plumbing.
6. On twin tank units, pull the 3/8” brine line through the hole in the back of the brine tank. Connect the brine line to the
fitting on the side of the valve using the nut and ferrule. Tighten snugly.
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
advance to the 1st 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 2nd cycle which is BRINE & SLOW
RINSE. 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 TANk 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 TANk REFILL 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. Put 40 kgs of crystal water softener salt in the brine tank. The unit will automatically fill to the correct level when it
regenerates.
(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 & SLOW
RINSE position. Allow softener to complete the BRINE & SLOW RINSE cycle, then press EXTRA CYCLE button three
times to advance valve back to service position.
