A TTENTION: SAFETY W

ARNINGS

:

Read and understand all warnings before installation or servic- ing pump.

Warning: Spraying Water Hazard

When servicing pump replace all gaskets and seals. Do not re-use old gaskets or seals. Failure to follow these instruc- tions could result in serious personal injury, death or proper- ty damage.

OPERATIONAL LIMITS

: *

Maximum Operating Pressure:

175 psi at Temperatures

 

to 150 O F (65.6°C)

Maximum Operating Temperature:

225°F (107°C)

*See ASTM A126/ANSI B16.1 for pressure/temperature rat- ings of flanges.

ELECTRICAL SAFETY:

HIGH PRESSURE SAFETY:

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: 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:

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.

Warning: Electrical Overload Hazard

Insure 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 lockout power source before servicing. Failure to follow these instructions could result in serious personal injury, death or property damage.

HIGH TEMPERATURE SAFETY:

Warning: Hot Surface Hazard

If pumping hot water, insure 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.

SERVICE

Your Aurora pump requires no maintenance other than periodic inspection, occasional cleaning and lubrication of bearings (MODEL 344A only). The intent of inspection is to prevent breakdown, thus obtaining optimum service life. The liquid end of the pump is lubricated by the fluid being pumped and there- fore does not require periodic lubrication. The motor, however may require lubrication, in which case, the motor manufactur- er’s recommendation should be followed.

LUBRICATION OF IMPELLER SHAFT BEARINGS

The MODEL 344A pump is available with three options for lubricating the shaft bearings. They are:

1.Regreasable (standard)

2.Oil Lubrication

3.Sealed Bearings, Permanent Lubrication

Regreasable bearings will require periodic lubrication and can be accomplished by using the zerk or lubrication fittings in the cartridge cap and power frame. Lubricate the bearings at regu- lar intervals using a grease of high quality. Polyurea base
