V. RESTARTING THE SYSTEM

Once the pump body, bearing assembly, and motor have been installed, a number of steps must be taken to make the system operational. Follow these instructions carefully in order to reduce the risk of system failure and/or personal injury.

WARNING: Hot Water Leakage Hazard Whenever the pump has been removed from the piping, use new flange gaskets when re-installing. Failure to follow these instructions could result in serious personal injury and/or property damage.

WARNING: Hot Water Leakage Hazard To prevent leakage, make certain that the flange bolts have been adequately torqued. Failure to follow these instructions could result in serious personal injury and/or property damage.

1. Filling and Venting the System

Filling and Venting the System

Open the pump suction and discharge valves. If the system was drained, it will be necessary to close the boiler drain valve and then open the shut off valve before the reducing valve to supply water to the boiler.

Eliminate air introduced into the system by venting it from a high point in the system or by an alternate method.

WARNING: High Pressure Hazard Pressurize the pump body slowly. Hot water leaks can occur. Check for leaks at all the joints with gaskets. Failure to follow these instructions could result in serious personal injury and/or property damage.
