11.6 Inlet pressure

To ensure optimum and quiet pump operation, the inlet pressure,
system pressure, must be adjusted correctly. See the table on
page 210.
For the calculation of specific inlet pressures, contact the local
Grundfos company.

11.7 Electrical data

See sections
31. Technical data, single-phase motors
32. Technical data, three-phase
For specific motor data, see the motor nameplate.

11.8 Sound pressure level

See section
34.2 Sound pressure

11.9 Environment

Non-aggressive and non-explosive atmosphere.

11.10 Installation altitude

Installation altitude is the height above sea level of the installation
site.
Motors installed up to 3281 ft (1000 m) above sea level can be
loaded 100 %.
The motors can be installed up to 6560 ft (2000 m) above sea
level.
Motors installed more than 3281 ft (1000 m) above
sea level must not be fully loaded due to the low
density and consequent low cooling effect of the air.
