Precautions
WARNING:
• When installing in a potentially explosive environment, make sure that the motor is
properly certified.
• You must ground (earth) all electrical equipment. This applies to the pump equipment,
the driver, and any monitoring equipment. Test the ground (earth) lead to verify that it
is connected correctly.
• Motors without built-in protection must be provided with contactors and thermal
overload protection for single-phase motors, or starters with heaters for three-phase
motors. (See the nameplate on the drive unit to select properly-sized overloads.)
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.
4.1.1 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.
If the pump is not on a closed system, locate the pump so that
the fewest number of bends or elbows in the suction pipe are
needed.
This minimizes the friction loss and keeps the
suction piping as short as possible.
Make sure that the space around the pump is sufficient. 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.
Take into consideration the occurrence of unwanted noise and
vibration.
The best pump location for noise and vibration
absorption is on a concrete floor with subsoil
underneath.
If the pump location is overhead, undertake special precautions
to reduce possible noise transmission.
Consider a consultation with a noise specialist.
Make sure there is a suitable power source available for the
pump driver.
The electrical supply must match the motor
nameplate specifications.
