INSTALLATION
GENERAL. The life of your Aurora
®
pump can be extended
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.
Warning: Electrical Shock Hazard
All electrical connections are to be made by a qualified elec-
trician in accordance with all codes and ordinances. Failure
to follow these instructions could result in serious personal
injury, death or property damage.
Warning: Electrical Overload Hazard
Ensure all motors have properly sized overload protection.
Failure to follow these instructions could result in serious
personal injury, death or property damage.
Warning: Sudden Start-up Hazard
Disconnect and lock out power source before servicing.
Failure to follow these instructions could result in serious
personal injury, death or property damage.
Warning: Hot Surface Hazard
If pumping hot water, ensure guards or proper insulation is
installed to protect against skin contact to hot piping or
pump components. Failure to follow these instructions could
result in serious personal injury, death or property damage.
Warning:
Spraying Water Hazard
When servicing pump, replace all gaskets and seals. Do not reuse
old gaskets or seals. Failure to follow these instructions could result
in serious personal injury, death or property damage.
Warning: High Pressure Hazard
The pump is rated at a maximum of 175 psi at 150°F.
Do not exceed this pressure. Install properly sized pressure relief
valves in system. Failure to follow these instructions could result in
serious personal injury, death or property damage.
Warning: Expansion Hazard
Water expands when heated. Install properly sized thermal
expansion tanks and relief valves. Failure to follow these
instructions could result in serious personal injury, death or
property damage.
