Safety instructions
The installation and commissioning as well as the connection of electrical components require
technical knowledge commensurate with a recognised vocational qualification as a fitter for
plumbing, heating and air conditioning technology, or a profession requiring a comparable
level of knowledge [specialist].
The following must be observed during installation and commissioning:
•
relevant local and national regulations
•

•
instructions and safety instructions of this manual
WARNING
Risk to life and limb due to electric shock!
Prior to commencing electrical work, pull the mains plug!
Only after completing all installation work, the mains plug of the
controller can be plugged into a socket. Thus, an unintentional start
of the motors is avoided.
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 of mineral oils, such as
Unisilikon L250L and Syntheso Glep 1 of the Klüber company or a silicone spray.
