WARNING: Electrical Shock Hazard Be certain that all connections are secure and the conduit box cover is closed before electrical power is re-connected. Failure to follow these instructions could result in serious personal injury or death.

Connect the electrical power to the boiler, pump and any related accessories. Return the system to normal operating condition. Check the pump and the surrounding piping for evidence of leaking and correct as required.

After a short period of operation, additional air should be vented from the system through a vent located at a high point in the system.
