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.
Please ensure for each pressure relief valve that no personal injury or
material damage may occur due to possibly escaping medium.
Install a discharge line.
Observe the instructions regarding the pressure relief valve.
The pressures calculated by the installation planner for the expansion
tank and the operating pressure of the installation must be set.
CAUTION
Personal injury and material damage due to overpressure!
Closing both ball valves in the primary circuit will separate the safety group from
the heat exchanger. A rise in temperature in the storage tank may result in high
pressures, which may lead to personal injury and material damage!
Only close the ball valves for service and maintenance.
