these instructions could result in serious personal injury, death and/or property damage.É
1. Close the valves on the suction and discharge sides of the pump. (If no valves have been installed, it may be
ÉÉÉÉnecessary to drain the system.)É
WARNING: - Hot Water Hazard - Before draining the system, allow water to cool to at least 100ºF (38ºC),
open the drain valve (take precautions against water damage) and leave the drain valve open until servicing
is complete. Failure to follow these instructions could result in serious personal injury, death and/or property
damage.É
WARNING: - Electrical Shock Hazard - Be certain the electrical power is not present at the motor leads before
continuing. Failure to follow these instructions could result in serious personal injury, death and/or property
damage.É
2.Loosen the conduit box cover screw and remove the cover.É
3. Disconnect the electrical supply lines to the pump.É
CAUTION: Excessive use of solder in a vertical installation may result in damage to the pump impeller. Do not
use excessive flux. Failure to follow these instructions could result in property damage and/or moderate
personal injury.É
4.When sweating the joints, first wrap the pump body with a cool wet rag, then direct the flame with care to avoid ÉÉÉÉÉÉÉ
subjecting the pump to excessive heat.
5.Check soldered connections for leaks. If re soldering is required, take care to avoid subjecting the pump to excessive
heat.É
WARNING: - WATER LEAKAGE HAZARD - To prevent leakage, make certain that the flange bolts or ring nuts
have been adequately tightened and that the solder connections do not leak. Failure to follow these
instructions could result in serious personal injury, death and/or property damage.É
6. Drain the plumbing lines by opening the faucet/tap in the house. Drain the water heater if you plan to make the
connection at the bottom of the water heater, which requires removal of the drain valve.
7. Connect the return line at the last faucet/taps riser and run to the water heater. Tee the return line as close to the end
of the hot water supply line as possible and run the return line back to the water heater.
8. Close the shut-off valve on the inlet side of the pump and turn the water supply to the house back on.
9. Flush system of debris. Before reattaching the pump motor, open the shut-off valve on the inlet side of the pump
housing and let water flow through the housing. Use a bucket to catch the water. Let the water run long enough to
clear all sand, solder pellets, plumbers tape flakes, etc. from the lines. Close the inlet shut-off valve when finished.
10. Connect the pump motor to the housing. Make sure the rubber o-ring is in place in the housing and the screw ring
is securely hand tightened. Reopen the shut-off valve or valves and let the water flood the pump housing.
fig. 1
Remove the motor unit and
o-ring from the pump housing into the plumbing
line. Do not sweat the housing into the plumbing
line with the motor or o-ring attached. Arrows on
the pump housing indicate the direction of water
flow.
Caution: Only hand tighten the screw ring.
Do not over tighten! Do not use plumbers
putty on the screw ring.
Do’s and Do Not’s
Do:
• Install an air vent mounted in a vertical position (if provided).
• Be sure the check valve is installed in the proper direction of the flow.
• Be sure all air is purged from the system prior to starting the pump.
• Use a water conditioner if you have hard water.
• Be sure the gate valves are open before turning on the pump.
• Install the pump pumping in upward direction only.
Do Not
• Use grease or oil to lubricate the pump (it is self-lubricating).
• Over tighten the screw ring.
• Install the pump with the motor above the pump housing.
• Install the pump pumping away from the water heater nor pumping downward.
• Start the pump before the system is full of water and purged of air.
• Use any pipe size other than 1/2”(5/8”) for all models.
Hard Water Conditions
Use a water conditioner. Hard water can cause scale build-up and eventually reduce the life of the pump and other
system components. Protected by one or more of the following Patents: 4580335, 4615662, 4822256, 4834628, 5094593, 5143049,

Power Source RequirementsÉ
In order to ensure full service life of the D Series pump, it is important to provide a stable and non-degrading power
source at the required voltage. Operating the pump out of the specified voltage range may reduce the life of the motor
and will void the warranty.
Electrical ConnectionÉ
• The pump is provided with 6” pigtails for field hard wiring. The red lead is positive.
• Be certain that correct polarity is observed.É
• Ensure that the electrical supply is correct and that the supply cable is suitable for the rated load indicated on the
pump label.É
•ÉWire the pump in accordance with your system application.É
• A quick function test without liquid is acceptable at this time. However, if the system is not filled with liquid, reduce
the time of this function test to an absolute minimum. The pump is liquid cooled and will build heat rapidly. Excessive
heat generated by dry run operation for extended periods will damage the pump.É
• After ensuring that the unit is functioning properly, fill the system and purge any air that may be trapped in the
system loop.É
System PreparationÉ
Prior to pump start-up, closed heating and cooling systems should be cleaned, drained, and refilled with clean water.
The system fluid pH must be maintained between 7 and 9.É
Start-UpÉ
Do not start pump until the system has been filled and vented. Air should be vented from the system by means of an air
vent located at a high point in the system. The system must be completely vented prior to pump operation. Do not run
ecocirc circulators dry. Pump operation without water circulation could result in pump and motor damage.É
• Open the isolation valves and any other valves that may have been closed during the pump installation.É
• Switch the pump on.É
• If you hear noise initially, this should abate after a short while as air is purged from around the impeller.É
• Power cycling the pump several times accelerates the air removal.É
• If the noise does not disappear or decrease substantially, purge the system once again.É
*Solar: It is recommended that the pump be left in the auto position for best results.É
Periodic InspectionÉ
Bell & Gossett ecocirc solar circulators are designed to provide years of trouble free service. It is recommended that
periodic inspections be made to check for potential problems with the pump. If any leakage or evidence of leakage is
present, repair or replace the unit.É
WARNING: - HOT WATER LEAKAGE HAZARD - Pressurize the body slowly while checking for leaks at all joints
with gaskets or solder connections. Failure to follow these instructions could result in serious personal injury
and/or property damage.
