How To Install Recirculating Pump On Tankless Water Heater

Step 1. Choose the appropriate place to install the Controller and the Flow Monitor :

Please refer to the Effigy below for installation options. Existing circulation pumps may be installed at Point A (hot water out), Point B (cold water in) or Point C (render line). Point C is the traditional installation betoken, but Points A and B are valid locations besides.

Ease of installation is the most important consideration when deciding. For the purposes of this manual the pump volition exist installed at Indicate A (hot h2o out).

Footstep 2. Turn off water heater.:

Turn off h2o heater to make certain information technology does not come up on during installation.

Pace 3. Turn off h2o:

Turn off the h2o to the water heater. In most cases there is a valve located below the h2o heater on the cold water supply line.

Stride iv. Drain the hot h2o lines:

Turn on any hot h2o faucet in the firm and allow it run until the h2o stops flowing. Exit the faucet on for the duration of the installation. Drain remaining hot water using the hot water spigot on the water heater.

Notation: If water continues to flow, check to make sure that the water has been completely turned off. If the valve does non shut off the water flow completely turn off the valve supplying water to the business firm or at the water meter.

Footstep 5. Cut the water line where the Period Monitor is to exist installed:

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

Pace 6. Orientation of Flow Monitor:

Make sure the arrows on the Menstruation Monitor are pointing in the management of catamenia.

Pace 7. Install the Flow Monitor :

Proper location of the Menses Monitor is disquisitional to the operation of the organisation. The Menstruation Monitor must exist installed outside the recirculation loop.

In Figure 3 beneath the loop includes 1-2, two-three, three-iv and 4-one. The pump will not cease in one case information technology starts if the Flow Monitor is installed anywhere inside the loop. It must be installed in the cold-water line outside of the loop. Shown as the Flow Monitor installation area in Figure three.

Hot Water Circulation Loop

Insert one gasket in the female cease of the Period Monitor (an extra gasket is provided). Using the appropriate fittings (not included) install the Flow Monitor in the cold-water line as indicated above. Practise non over tighten.

Warning: do not over tighten.

Stride 8. Complete connections and turn on water:

Brand sure that a hot water faucet is turned on in the firm and then slowly plough 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.

Footstep 9. Connect the Pump Manager and the Flow Monitor:

Locate the Pump Manager in proximity to the pump, the Flow Monitor and an electrical outlet.

Connect the ii wires from the Flow Monitor to the 2 wires from the Pump Manager. The color of the wires does not thing. Use thermostat wire (or equivalent) if the wires demand to exist extended.

Notation: If yous have a multi speed pump set up pump the highest speed.

Step 10. Connect the pump and the Pump Manager:

Plug the Pump Manager into a properly grounded 110 vAC outlet. Then plug the pump into the Pump Director.

Step 11. Test Dedicated Recirc System:

Plow on any hot water faucet in the business firm for 1 2nd and plough it off. Pump will continue to operate for approximately 180 seconds later on the faucet has been turned off.

Annotation: The 180 second timer will not start until all demand for hot h2o has ended.

Electrical Information
