Safety
WARNING:
• The operator must be aware of safety precautions to prevent physical injury.
• Any pressure-containing device can explode, rupture, or discharge its contents if it is over-pressurized.
Take all necessary measures to avoid over-pressurization.
• Operating, installing, or maintaining the unit in any way that is not covered in this manual could cause
death, serious personal injury, or damage to the equipment. This includes any modification to the
equipment or use of parts not provided by ITT. If there is a question regarding the intended use of
the equipment, please contact an ITT representative before proceeding.
• Installation, Operation, and Maintenance manuals clearly identify accepted methods for disassembling
units. These methods must be adhered to. Trapped liquid can rapidly expand and result in a violent
explosion and injury. Never apply heat to impellers, propellers, or their retaining devices to aid in their
removal.
• Do not change the service application without the approval of an authorized ITT representative.
• Never operate the pump below the minimum rated flow, when dry, or without prime.
• Never operate the pump without safety devices installed.
• Never operate the pump with the discharge valve closed.
• Never operate the pump with the suction valve closed.
