Installation and Start-up
1. Turn off the main water supply to the OneFlow System and
open an inside faucet to relieve any pressure within the
plumbing system. Close the inside faucet once pressure is
released.
2. 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.
3. 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.
4. Place a bucket under the outlet port or run a line from the
outlet port to a drain.
5. Turn the water back on to the OneFlow system. Slowly open
the supply valve (user supplied) 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.
6. Connect the outlet of the OneFlow
®
system to the cold water
supply to the building.
7. Open the supply valve to the OneFlow
®
system.
8. Open hot and cold faucets downstream from the OneFlow
®
system to relieve any air from the plumbing system. Then
close the faucets.
9. Check for leaks. Repair as needed.
