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 overpressurized. 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.
• This manual clearly identifies 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 unless explicitly stated in this manual.
• If the pump/motor is damaged or leaking, do not operate as it may cause an electric shock, fire, explosion, liberation of toxic fumes, physical harm, or environmental damage. Correct/ repair the problem prior to putting back in service.
• Do not change the service application without the approval of an authorized ITT representative.
