Equipment Specifications
Watts OneFlow
®
+ systems are complete, self-contained,
loaded with media and ready to use. A simple inlet and outlet
connection is all that is required for installation. Please review
operating pressures, temperatures and water chemistry
limitations to ensure compatibility and performance.
Using OneFlow
®
+ systems with other water
treatment equipment.
There are some unique requirements for using OneFlow
®
+
systems in conjunction with other forms of water treatment.
1. OneFlow
®
+ system must be the last stage in the treatment
chain. Do not install any filters after the OneFlow
®
system or
before any devices for which scale prevention is required.
2. Do not apply antiscalant before or after the OneFlow
®
+
system.
Setup
Unpack and check the system components for damage or
missing parts.
Installation Considerations
Consider the following points when determining where to install
the system:
• Do not install the system where it would block access to
the water heater, main water shutoff, water meter, or
electrical panels.
• Install the system in a place where water damage is least likely
to occur if a leak develops.

The overall height and the height of the inlet fitting varies due to material variations and assembly
tolerances. Please allow additional clearance above the filter for making connections.
