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.
Step 6. Orientation of the Flow Monitor:
Make sure the arrows on the Flow Monitor are pointing in the direction of flow.
Step 7. Existing pump:
Correct installation of the pump can be either horizontal or vertical. Use proper straps for support if necessary.
Step 8. Install the Flow Monitor:
Make sure the gasket is inserted in the female end of the Flow Monitor. Do not over tighten.
Step 9. Complete connections and turn on water:
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. Turn off the faucet.
Step 10. Connect the Pump Manager and the Flow Monitor:
Connect the wires from the Flow Monitor to the wires from the Pump Manager.
Set pump toggle switch to III (3 bars) setting for the highest speed.
Step 11. Plug the pump in:
Plug the pump into the Pump Manager and plug the Pump Manager into a properly grounded 110 vAC outlet.
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.
