RF emission
GB 4824
Group I
The high-flow device used
RF energy only for its internal function.
Therefore, the high-flow device has very low
RF emissions and other electronic devices in
the vicinity are very unlikely to be disturbed.
RF emission

Type B
Harmonious emission
Type A
The high-flow device is suitable for use in all
facilities, including in residential buildings with
a direct connection to a public low-voltage
network for residential buildings.

Guidelines and manufacturer's declaration on electromagnetic emissions:
The high-flow device is intended for use in the electromagnetic environ
-
ment described below. The buyer and the user should ensure that the
high-flow device is in such an electromagnetic environment.
