1 Introduction and Safety
1.1 Safety
WARNING:
•
The operator must be aware of the pumpage and take appropriate safety precautions to
prevent physical injury.
•
Risk of serious injury or death. If any pressure-containing device is over-pressurized, it
can explode, rupture, or discharge its contents. It is critical to take all necessary meas-
ures to avoid over-pressurization.
•
Risk of death, serious personal injury, and property damage. Installing, operating, or
maintaining the unit using any method not prescribed in this manual is prohibited. Prohib-
ited methods include any modification to the equipment or use of parts not provided by
ITT. If there is any uncertainty regarding the appropriate use of the equipment, please
contact an ITT representative before proceeding.
•
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.
•
Risk of serious personal injury or property damage. Dry running may cause rotating parts
within the pump to seize to non-moving parts. Do not run dry.
•
Running a pump without safety devices exposes operators to risk of serious personal in-
jury or death. Never operate a unit unless appropriate safety devices (guards, etc.) are
properly installed. See specific information about safety devices in other sections of this
manual.
•
Risk of death, serious personal injury, and property damage. Heat and pressure buildup
can cause explosion, rupture, and discharge of pumpage. Never operate the pump with
suction and/or discharge valves closed.
•
Risk of severe physical injury or death from explosion of trapped liquid. Never use heat to
remove parts unless explicitly stated in this manual.
•
Always lockout power to the driver before performing pump maintenance.
•
Never operate any pumping system with a blocked suction and discharge. Operation,
even for a brief period under these conditions, can cause confined pumped fluid to over-
heat. If pump becomes plugged, shut down and unplug prior to restarting pump.
•
Precautions must be taken to prevent physical injury. The pump may handle hazardous
and/or toxic fluids. Proper personal protective equipment should be worn. Pumpage must
be handled and disposed of in conformance with applicable environmental regulations.
•
If the pump or motor is damaged or leaking, electric shock, fire, explosion, liberation of
toxic fumes, physical harm, or environmental damage may result. Do not operate the unit
until the problem has been corrected or repaired.
CAUTION:
Risk of injury and/or property damage. Operating a pump in an inappropriate application can
cause over pressurization, overheating, and/or unstable operation. Do not change the service
application without the approval of an authorized ITT representative.
