Instructions for any BRG-E, BRG-F or BRG-G Assembly
WARNING:
Before proceeding with any of these instructions, make certain that power is disconnected and
locked out. Electrical power to the boiler and any related accessory must also be disconnected and locked out.
Failure to follow these instructions could result in injury or death.
WARNING:
Check surfaces for high temperatures. Allow the pump/piping temperature to reach approximately
100°F before proceeding. Failure to follow these instructions could result in severe personal injury and/or prop-
erty damage.
CAUTION:
Close the valves on the suction and discharge sides of the pump before proceeding. If no valves
have been installed, it will be necessary to drain the system. If it becomes necessary to drain the system, close
the city water supply or shutoff valve to the pressure reducing valve. Allow the system to cool to approximately
100°F. Open the drain valve (take precautions against water damage) and leave the drain valve open until ser-
vicing is completed. Failure to follow these instructions could result in severe personal injury and/or property
damage.
