Disassembly precautions
WARNING:
• Failure to disconnect and lock out driver power may result in serious physical injury or
death. Always disconnect and lock out power to the driver before performing any
installation or maintenance tasks.
• Electrical connections must be made by certified electricians in compliance with all
international, national, state, and local rules.
• Refer to driver/coupling/gear manufacturer's installation and operation manuals (IOM)
for specific instructions and recommendations.
• Risk of serious personal injury. Applying heat to impellers, propellers, or their retaining
devices can cause trapped liquid to rapidly expand and result in a violent explosion. This
manual clearly identifies accepted methods for disassembling units. These methods must
be adhered to. Never apply heat to aid in their removal unless explicitly stated in this
manual.
• Handling heavy equipment poses a crush hazard. Use caution during handling and wear
appropriate Personal Protective Equipment (PPE, such as steel-toed shoes, gloves, etc.)
at all times.
• Risk of serious physical injury or death from rapid depressurization. Ensure pump is
isolated from system and pressure is relieved before disassembling pump, removing
plugs, opening vent or drain valves, or disconnecting piping.
• Risk of serious personal injury from exposure to hazardous or toxic liquids. A small amount
of liquid will be present in certain areas like the seal chamber upon disassembly.
• Risk of severe physical injury or death from explosion of trapped liquid. Never use heat to
remove parts unless explicitly stated in this manual.
CAUTION:
• Avoid injury. Worn pump components can have sharp edges. Wear appropriate gloves
while handling these parts.
