Using the gaskets supplied with the kit or those supplied with the shut off valves (if used) mount the circulator between the attached valves or
fittings.
10. Close the faucets that were opened.

“Caution”
Do not use flexible hoses to connect the pump to the homes plumbing. Use only ridged piping.
12. When all piping has been connected and sealed pressurize the system by opening the water supply valve and check for leaks.
13. If a leak occurs shut off the water supply valve, drain the system and repair the leak.
14. To clear air from the pump and the system open a faucet and allow water to flow until the stream becomes steady. Close the faucet.
15. Plug in the pump into a GFCI outlet. The timer switch is set in the on position. Do not change this setting if the On Demand transmitter receiver
are being used.
16. Recheck for leaks and correct as necessary.
Mounting Orientation
To protect the circulator from water intrusion the box must always be mounted facing upwards as shown
Operation
The circulator will run based on the activation of the wireless button. When the temperature of the water being pumped reaches 92
⁰ F the ODR
valve will adjust itself to maintain the temperature at the fixture. The circulator will continue to run for 5 minutes. The length of time that the
circulator runs can be extended by reprograming the receiver for 15 or 30 minutes if hot water needs to be maintained for a longer period.
Pressing the wireless button while the circulator is running will reset the run time for 5 minutes or the reprogramed time you selected.
The circulator does not offer freeze protection because of the On Demand Kit.
Valve Installation
Installation and Operating Instructions
Warning: This is not an anti-scald valve.
AMK-ODR Valve Installation
Note: Pipe dope and Teflon tape are Not required for any of the valve threads.
*See AMK-WB Instructions for On Demand installation.
The valve is normally installed at the faucet that is furthest away from the hot water tankless heater. If there are separate hot water branches in the
residence, additional valves may be required.
1) Close both the hot and cold angle shut off valves under the sink.
2) Open both the hot and cold water faucets to relieve the water pressure.
3) Place a pan or rag below the connections to catch any water that may leak
from the risers.
4) Disconnect the riser pipes or hoses from the angle shut off valves.
5) Install the ODR valve onto the
Cold Water Angle Stop
using the 3/8”
compression nut on the ODR valve.
6) Attach the cold water riser to the ODR valve.
7) Install the Tee from the kit to the Hot Water Angle Shut Off
valve using the 3/8”
compression nut on the Tee.
8)
Attach the ½” hose from the kit between the ½” connection on the ODR valve
and the ½” connection on the Tee.
9) Open the hot water angle shut off valve and the cold water faucet to purge air
from the line and valve.
10) Close the cold water faucet and open the cold angle stop valve.
Note: The spacing dimensions between angle shut offs vary. Position the valve and Tee hose connections to suit your system.
