Installation and Start-up
1. Turn off water heater(s).
2. Turn off the main water supply to the home and open an
inside faucet to relieve any pressure within the plumbing sys-
tem.
3. Place the system in the desired location. Make sure that the
location is level and sturdy enough to support the weight of
the wetted system.
4. Place the bypass valve in the up flow service position. See
below Bypass Valve Modification Detail.
5. Connect the cold water supply to the inlet of the OneFlow ®
system. NOTE: The OneFlow ® system operates in the
UP-flow mode which is opposite of a conventional softener.
Follow the plumbing diagram in Figure 3.
6. Install a supply valve (user supplied) in the supply line and
close it.
7. Place a bucket under the outlet port or run a line from the
outlet port to a drain.
8. Turn the water back on to the house. Slowly open the sup-
ply valve to the OneFlow ® system. Allow the tank to fill with
water. Close the supply valve when a steady stream of
water comes out of the outlet port. If the outlet is flowing
into a bucket, water could splash on nearby objects. If this
threatens the safety, value, structure, or appearance of these
objects, protect/remove them or use the outlet hose to drain
option.
9. Close the inside faucet.
10. Connect the outlet of the OneFlow
® system to the cold
water supply to the house.
11. Open the supply valve to the OneFlow ® system.
12. Open hot and cold faucets downstream from the OneFlow ®
system to relieve any air from the plumbing system and
water heaters. Then close the faucets.
13. Check for leaks. Repair as needed.
14. The system is now ready for service.

As shipped, the bypass is set-up for down-
flow use. The arrow shape of the handles
points in the wrong direction for UP-flow
use. To convert it to UP-flow use, pull up on
the red handles until they come off. Rotate
the handle 180° and put it back on the valve
stem.
