WARNING

NEVER use heat to disassemble pump due to risk of explosion from tapped
liquid.

WARNING

NEVER operate pump without coupling guard correctly installed.

WARNING

ALWAYS lock out power to the driver before performing pump maintenance.

WARNING

NEVER operate pump without safety devices installed.

WARNING

Safety Apparel:

Insulated work gloves when handling hot bearings or using bearing
heater

Heavy work gloves when handling parts with sharp edges, especially
impellers

Safety glasses (with side shields) for eye protection

Steel-toed shoes for foot protection when handling parts, heavy tools,
etc.

Other personal protective equipment to protect against hazardous/toxic
fluids

WARNING

Receiving:

Assembled pumping units and their components are heavy. Failure to properly
lift and support equipment can result in serious physical injury and/or equip-
ment damage. Lift equipment only at specifically identified lifting points or as
instructed in the current IOM. Current manuals are available at www.gould-
spumps.com/literature_ioms.html or from your local ITT Goulds Pumps sales
representative. Note: Lifting devices (eyebolts, slings, spreaders, etc.) must
be rated, selected, and used for the entire load being lifted.

WARNING

Before beginning any alignment procedure, make sure driver power is locked
out. Failure to lock out driver power will result in serious physical injury.

WARNING

Flanged Connections:

Use only fasteners of the proper size and material.

WARNING

Replace all corroded fasteners.

WARNING

Ensure all fasteners are properly tightened and there are no missing fasten-
ers.

WARNING

Lock out driver power to prevent accidental start-up and physical injury.

WARNING

Never operate a pump without coupling guard properly installed. Personal in-
jury will occur if pump is run without coupling guard.

WARNING

Never attempt to replace packing until the driver is properly locked out and the
coupling spacer is removed.

WARNING

Ensure pump is isolated from system and pressure is relieved before disas-
sembling pump, removing plugs, opening vent or drain valves, or disconnect-
ing piping.

WARNING

Shutdown, Disassembly, and Reassembly:

Pump components can be heavy. Proper methods of lifting must be employed
to avoid physical injury and/or equipment damage. Steel toed shoes must be
worn at all times.

WARNING

The pump may handle hazardous and/or toxic fluids. Observe proper decon-
tamination procedures. Proper personal protective equipment should be worn.
