NOTICE
Installation diagrams for specific system models can be found on

Unpack the contents of the U-M311 carton and confirm all
components are present in the kit. A complete kit includes
monitor, flow meter, meter cable, power transformer/cable and
monitor mounting hardware. If any components are missing,
please contact your Watts representative.
1. Install the 1" flow meter in the conditioned water outlet line of

point in the direction of water flow. See Figure 1.
Use PTFE plumbing tape only on the meter threads.
2. Lift up on tab at bottom center of U-M311 monitor display

Mounting hardware is provided for drywall mounting. Installer

surface types.
