Technical Information
8.1
Operating environment
Temperature
From -20 to 50°C (-4-122°F), unless otherwise indicated on the data plates of the pump and
the electric motor.
Relative air humidity
< 50% at 40°C (104°F), unless otherwise indicated in the instructions of the pump and the
electric motor.
NOTE:
If the humidity exceeds the stated limits, contact Xylem or the Authorised Distributor.
Elevation
< 1000 m (3280 ft) above sea level.
NOTE: Danger of motor overheating
If the unit is exposed to temperatures or installed at an altitude greater than those stated, refer
to the motor manufacturer's instructions and catalogues to reduce the power output of the
motor or replace it with a more powerful model.
