ATTENTION
Material damage due to mineral oils!
Mineral oil products cause lasting damage to seals made of EPDM, whereby the sealant
properties are lost. We do not assume liability nor provide warranty for damage to property
resulting from sealants damaged in this way.
It is imperative to prevent the EPDM sealing elements from making contact with
substances containing mineral oils.
Use a silicone- or polyalkylene-based lubricant free of mineral oil, such as
Unisilikon L250L and Syntheso Glep 1 from Klüber or a silicone spray.
ATTENTION
Material damage due to high temperatures!
Since the solar fluid near the collector can be very hot, the group of fittings must be installed at
a sufficient distance from the collector field. It may be necessary to install an intermediate tank
in order to protect the expansion tank.
