7.1. Free air delivery (FAD) correction due to elevation
Capacity given in the form of FAD („Free Air Delivery") applies to the following conditions:
Altitude
Atmospheric pressure
To calculate FAD compressor capacity in dependence on altitude, it is necessary to apply
correction factor according to the following table:
Altitude [m.n.m.]
FAD correction factor

Electromagnetic environment - guidance
The equipment uses RF energy only for its
internal functions. Therefore, the RF emissions
are very low and are not likely to cause any
interference in nearby electronic equipment.
The equipment is suitable for use in all
establishments, including domestic
establishments and those directly connected to
the public low voltage power supply
network that supplies buildings used for domestic
purposes.
