Recirculation Instructions
NOTE: Recirculating the water in the system provides constant regulation of the water temperature.
Flush the supply lines thoroughly after completing installation. Close off all fixtures and label
them as not in use during the recirculating process.
1. Turn off the recirculating pump and turn on the water supply (a water flow rate of 10-15
GPM is required).
2. Let the water run through the system until a consistent temperature is obtained. If you do not
obtain the required temperature, refer to procedure #6 on page 3 for temperature readjustment.
3. As soon as the water reaches the proper temperature, turn on the recirculating pump (make
certain the proper system temperature has been achieved before proceeding).
4. Check the water temperature at the return pump. If the temperature exceeds the appropriate
level by 2°F, adjust the temperature high-limit switch (this will turn off the pump). Wait until
the return water temperature is 5°F below the appropriate level and adjust the low limit
switch (this will turn the pump back on).
5. Turn the balancing valve until it is completely open.
6. Turn off all fixtures and make sure there is no water running through the system (the cold
inlet pipe should feel warm to the touch).
7. Let the system run for thirty minutes or longer without water. If, after thirty minutes, the
water temperature increases, you may readjust the temperature by slowly closing the balancing
valve until the appropriate temperature is reached.
