2.2 Operating conditions

A normal construction fan is intended for the circulation
of air when air conditioning. If the air being circulated
contains explosive gases, check whether the fan is
suited for the prevailing conditions on a case by case
basis. The standard operating temperature of a fan
is -30...+80°C. Motor efficiency values are valid when
the ambient temperature does not exceed +40°C,
and the installation location is maximum 1000 m above
the sea level. If installed on the exterior of a building,
the motor must be protected from direct sunlight.

2.3 Noise emissions

Noise level generated by the fan might exceed 70 dB(A)
in normal operation. More detailed performance figures
can be found in the product brochure.

2.4 Balancing

The impeller has been balanced dynamically and the
fan has been test run at the factory, with a vibration level
(measured from its bearings) of <7.1 mm/s (RMS).
