Precautions
WARNING:
• When installing in a potentially explosive environment, make sure that the motor is
properly certified.
• You must earth (ground) all electrical equipment. This applies to the pump equipment,
the driver, and any monitoring equipment. Test the earth (ground) lead to verify that it is
connected correctly.
NOTICE: Supervision by an authorized Xylem representative is recommended to ensure
proper installation. Failure to do so may result in equipment damage or decreased
performance.
Pump location guidelines
WARNING:
Assembled units and their components are heavy. Failure to properly lift and support this
equipment can result in serious physical injury and/or equipment damage. Lift equipment
only at the specifically identified lifting points. Lifting devices such as eyebolts, slings, and
spreaders must be rated, selected, and used for the entire load being lifted.
Guideline Explanation/comment
Keep the pump as close to the liquid source as
practically possible.
This minimizes the friction loss and keeps the suction
piping as short as possible.
Make sure that the space around the pump is sufficient.
Also make sure that you can protect the area below the
pump from water damage.
This facilitates ventilation, inspection, maintenance, and
service.
If you require lifting equipment such as a hoist or tackle,
make sure that there is enough space above the pump.
This makes it easier to properly use the lifting
equipment and safely remove and relocate the
components to a safe location.
Protect the unit from weather and water damage due to
rain, flooding, and freezing temperatures.
This is applicable if nothing else is specified.
Do not install and operate the equipment in closed
systems unless the system is constructed with properly-
sized safety devices and control devices.
Acceptable devices:
• Pressure relief valves
• Compression tanks
• Pressure controls
• Temperature controls
• Flow controls
If the system does not include these devices, consult the
engineer or architect in charge before you operate the
pump.
Take into consideration the occurrence of unwanted
noise and vibration.
Vibration can be transmitted to the piping system,
which can result in objectionable noise away from the
pump.
