4.1. Room temperature and altitude

When the room temperature is over 40ºC or the pump has been installed over 1000
meters altitude, the motor should not operate at full capacity, since there is a risk of
overheating as indicated in Figure 3. Overheating may be caused by excessive room
temperature or low air density with insufficient refrigeration capacity.
In those cases where both, room temperature and altitude are surpassed, correction
factors must be enhanced.
In both cases, a motor with a greater nominal power would be desirable.
