INSTALLATION
GENERAL. The life of your Aurora
considerably by carefully following the installation instructions
contained herein. Each step of the pump installation instructions
plays a vital part in assuring long life, efficient operation and
reduced maintenance, from the initial location of the pump
through prestarting directions.
UNPACKING YOUR PUMP. The crate containing your pump
should be opened immediately upon receipt from the factory,
and the pump generally inspected for damage and shortage of
parts. Particular attention should be given to the discharge and
suction nozzle threads or flanges. Any damage or shortage of
parts should be reported to the carrier immediately.
PLANNING THE PUMP LOCATION. You probably have
spent considerable time planning where your pump will be
located. However, you may have overlooked some factor that
may affect pump operation or efficiency.
The pump should be located as close to the liquid source as
possible so that the suction line can be short and direct. It should
be located in a clean, open area, where it is easily accessible for
inspection, disassembly and repair. Pumps installed in dark, dirty
areas or in cramped locations are often neglected, which can
result in premature failure of both the pump and the driver.
