Measurement
conditions:
Measured with a double chamber intake rig acc. to DIN EN ISO 5801.
Normal air density = 1,2 kg/m3; Temperature 23°C +/- 3°C;
In the intake and outlet area should not be any solid obstruction within 0,5 m.
The information is only valid under the specified test conditions and may be changed by the
installation conditions. If there are deviations from the standard test conditions, the
characteristic values must be checked under the installed conditions.

4.1 General
4.2 Climatic requirements*)
Product Data Sheet ACi 4420 MLR
*) Permittet application area:
The product is for the use in sheltered rooms with limited controlled temperature. Occasionally condensed water is
allowed. Direct exposure to water must be avoided. Saline ambient conditions must be avoided.
Pollution degree 2 (according DIN EN 60664-1)
It occurs only non-conductive pollution. Occassionally, temporary conductivity caused by condensation occurs.

A verification of thermal conditions (normal and abnormal operation) as well as the protection against electric shock,
ingress of solid foreign objects and water has to be done in conjuction with the appliance.
