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 mentioned in these instructions.

WARNING
Danger of scalding due to the escape of hot fluids!
With pressure relief valves, there is a risk of scalding due to the escape of vapour or hot fluid. During installation, check the local conditions and check whether a discharge line must be connected to the safety group.
- Observe the instructions regarding the pressure relief valve.
- The pressures for the expansion tank calculated by the plant designer and the operating pressure of the installation must be set.

CAUTION
Personal injury and damage to property!
The product must only be used in heating circuits filled with heating water according to VDI 2035 / Ö-Norm H 5195-1. The product must not be used in domestic water applications.

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 the EPDM sealing elements of the unit get 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.
