The Dedicated Recirc System – Controller Only converts an existing hot water circulation pump into an efficient on-demand delivery system.
The Dedicated Recirc System – Controller Only 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 the pump and rushes water out to where it is needed.
The Pump Manager will run the pump for approximately 1 minute to ensure that hot water is available throughout your home (adjustable from 1 minute to 60 minutes).
Step 1. Inspect your water heater supply lines:
If the supply lines are old and inflexible they may need to be replaced.
Step 2. Turn off water heater:
Electric – turn off power by either unplugging the water heater or shutting off the appropriate breaker.
Gas, propane or heating oil – turn off water heater and make sure the pilot light is turned off.
Step 3. Turn off water:
Turn off the water to the water heater. In most cases there is a valve located above 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. Disconnect the cold water supply line:
Unscrew the cold water supply line where the cold water comes in to the water heater (typically the right supply line).
Step 6. Install the Flow Monitor:
Make sure the gasket is inserted in the female end of the Flow Monitor.
Carefully thread the female end of the Flow Monitor on to the nipple coming out of the top of the water heater with the arrow pointing down (the direction of water flow). Do not over tighten.
Note: Flow Monitor will not work properly if the arrow is pointing up. Make sure the arrow is pointing toward the female end (see picture). If it is not, remove the 4 screws and turn the black portion of Flow Monitor 180°. Reinsert screws and tighten.
Warning: do not over tighten.
Step 7. Re-connect the cold water supply line:
Screw cold water supply line onto the Flow Monitor.
Step 8. Prepare existing pump:
Unplug the existing circulation pump.
Step 9. Install Pump Manager:
Plug new pump into the Pump Manager and plug the Pump Manager into a properly grounded 110 vAC outlet.
Note: Route the cord away from any vents on gas, propane or oil fired water heaters, if necessary.
Step 10. Turn water back on:
Make sure that a hot water faucet is turned on in the house and then slowly turn the water back on to the water heater. Check for leaks and repair as necessary. Leave the water running until all of the air has been purged from the water pipes including all hose bibs. Turn off the faucet.
Step 11. Connect the Flow Monitor to the Pump Manager:
Connect the low voltage wires from the Flow Monitor to the Pump Manager using the proper wire connectors. If extra length is required standard thermostat wire can be used.
Step 12: Test Dedicated Recirc System:
Turn on any hot water faucet in the house for 1 second and turn it off. Pump should continue to operate for approximately 60 seconds after the faucet has been turned off.
Note: The 60 second timer will not start until all demand for hot water has ended.
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.
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.
The Dedicated Recirc System can be used with both tank style water heaters and tankless water heaters. These instructions are for installation on a tank style water heater. Please refer to the appropriate manual for tankless installations.
A portion of the Dedicated Recirc System is installed in the cold water line on top of a tank style water heater and/or the dedicated return line. 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.
