9.10 Installation altitude
Installation altitude is the height above sea level of the installation
site.
• Motors installed up to 1000 metres above sea level can be
loaded 100 %.
• Motors installed more than 1000 metres above sea level must
not be fully loaded due to the low density and consequent low
cooling effect of the air. See fig. 25.

altitude above sea level
9.11 Humidity
Maximum humidity: 95 %.
If the humidity is constantly high and above 85 %, one of the drain
holes in the drive-end flange must be open.
See section 6. Mechanical installation.
9.12 Motor cooling
To ensure cooling of motor and electronics, observe the following:
• Position the motor in such a way that adequate cooling is
ensured. See section 6.7 Ensuring motor cooling.
• The temperature of the cooling air must not exceed 50 °C.
• Keep cooling fins and fan blades clean.
10. User interfaces
You can make pump settings by means of the following user
interfaces:
Control panels
• Standard control panel.
See section 11. Standard control panel.
• Advanced control panel.
See section 12. Advanced control panel.
Remote controls
• Grundfos GO.
See section 13. Grundfos GO.
If the power supply to the pump is switched off, the settings will
be stored.
Factory settings
TPE2, TPE2 D pumps have been factory-set to constant-curve
control mode. See section 11.1.2 Pump in constant-curve control
mode.
The setpoint corresponds to 100 % of the maximum pump
performance. See data booklet or Grundfos Product Center.
TPE3, TPE3 D pumps have been factory-set to AUTO
ADAPT
control mode. See section 14.5.1 AUTOADAPT.
The motor must not be installed more than 2000
metres above sea level.
