Product Overview

The Dedicated Recirc System converts a hot water circulation line into an efficient on-demand delivery system.

The Dedicated Recirc System delivers hot water only when there is a demand:

  • Reducing Energy Costs &
  • Virtually Eliminating Pinhole Leaks

When the Flow Monitor detects a hot water demand the Pump Manager turns on your existing pump and rushes water out to where it is needed.

The Pump Manager will run the pump for approximately 3 minutes to ensure that hot water is available throughout your home. (adjustable from 1 second to 167 hours)

Step 1. Inspect your existing pump:

If the pump has not been operating properly or shows any visible signs of wear it may need to be replaced.

Step 2. Turn off water heater:

Turn off water heater to make sure it does not come on during installation.

Step 3. Turn off water:

Turn off the water to the water heater. In most cases there is a valve located near the water heater on the cold water supply line.

Step 4. Drain the hot water lines:

Turn on any hot water faucet in the house and let it run until the water stops flowing. Leave the faucet on for the duration of the installation. Drain remaining hot water using the hot water spigot on the water heater.

Note: If water continues to flow, check to make sure that the water has been completely turned off. If the valve does not shut off the water flow completely turn off the valve supplying water to the house or at the water meter.

Step 5. Cut the cold water feed to the water heater where the Flow Monitor is to be installed:

Remove a section of pipe equivalent to the length Flow Monitor plus any extra length for required fittings.

Electrical Information

Safety Warning

Risk of Electrical Shock

This pump is supplied with a grounding conductor. To reduce the risk of electrical shock, be certain that it is connected only to a properly grounded grounding type receptacle.

The safe operation of this pump requires that it be grounded in accordance with the national Electrical Code and local government regulations.

Operating Instructions

To activate the Dedicated Recirc System, simply turn on any hot water faucet in the house and quickly turn it off.

This will start the pump which will run for approximately 60 seconds. Typically it takes about 10 to 15 seconds to heat up the entire circulation line. Once the line is hot you will have hot water everywhere you want it.

The pump will shutoff approximately 60 seconds after the demand for hot water ends.

Installation Notes:

The Dedicated Recirc System can be used with both tank style water heaters and tankless water heaters. These instructions are for installation on a tankless water heater. Please refer to the appropriate manual for tank style installations.

A portion of the Dedicated Recirc System is installed in the cold water line in or the hot water line out of a tankless water heater. Failure to follow these instructions may lead to system failure and/or property damage. Although a plumber is not required to install the system familiarity with basic plumbing is necessary.
