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 

 

accident prevention regulations of the professional association 

 

instructions and safety instructions of this manual 

 
 

 

 

CAUTION 

Personal injury and damage to property! 
The HeatBloC

®

 must only be used in heating circuits filled with heating water 

according to VDI 2035 / Ö-Norm H 5195-1. 
The HeatBloC

®

 must not be used in drinking water applications. 

 

ATTENTION 

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 silicone- or polyalkylene-based lubricant free of mineral oil such as Unisilikon 
L250L and Syntheso Glep 1 from Klüber or a silicone spray.
