NOTICE
Material damage due to mineral oils!
Mineral oil products cause lasting damage to seals made of EPDM, whereby the sealant
properties get lost. We do not assume liability nor provide warranty for damage to property
resulting from sealants damaged in this way.
It is imperative to avoid that EPDM gets in contact with substances containing mineral
oils.
Use a lubricant based on silicone or polyalkylene and free from mineral oils, such as
Unisilikon L250L and Syntheso Glep 1 of the Klüber company or a silicone spray.
NOTICE
Malfunction!
The domestic hot water module must be integrated in the potential equalisation of the
electric installation. This can be guaranteed by establishing a potential equalisation
connection to the main potential connection according to regulations or by the connected
pipe system.
