Installation
1. Place the system in the desired location. Ensure adequate
clearance so the the bypass valve can be operated when
necessary.
NOTE:
System must be operated in a vertical
position. Do not lay it down during operation.
2. Connect the Hot Water supply to the inlet of the OneFlow
®
system. We recommend the use of the flexible Stainless
Steel connectors (not suppled with the system but available
from Watts). Observe standard plumbing practices and local
plumbing codes.
NOTE:
The OneFlow
®
system operates in the Upflow mode
which is opposite of a conventional softener. (The arrows cast
into the bypass valve are intended for a conventional softener
and are, therefore, the OPPOSITE of the correct OneFlow
®
operating flow.)
3. Place the bypass valve in the SERVICE position (as shown
in Figure 1).
4. Place a bucket under the outlet port or run a line from the
outlet port to a drain.
5. 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.
6. Connect the Outlet of the OneFlow
®
system to the line feed-
ing the appliance that requires pre-heated water.
7. Open the supply valve to the OneFlow
®
system.
8. Operate the fill cycle on the attached equipment to clear the
line(s) of air bubbles.
9. Check for leaks. Repair as needed.
10. The system is now ready for service.
