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.
