Pre Installation
From 2018, electric room heaters must comply with Eco design Directive 2009 / 125 / EG. The aim of this
regulation is to save energy in the context of environmental protection.
The R4 fully complies with this regulation. Thus making any radiator fitted with the R4 compliant. This is
a necessity if the radiator is specified to be used as the room’s primary source of heat.

The R4 is a 230V (class I) appliance and must be connected to either a plug socket (if this is permitted
in the respective country) or to a fused connection box (according to the local regulations). Please
