WARNING
Danger to life due to suffocation!
There is a risk of suffocation if refrigerant escapes, as refrigerant is odorless and
tasteless and displaces atmospheric oxygen.
• A refrigerant sensor for monitoring the installation site and suitable ventilation
must be present and functional.
• Observe the safety data sheet of the refrigerant.
• Leave the danger zone.
• Ensure good air exchange in the danger zone.
• Use self-contained respiratory protection.
WARNING
Danger to life due to suffocation!
If the refrigeration circuit is completely emptied, there is a risk of asphyxiation, as
vapors, aerosol or gases can spread through the duct in the building.
• Maintain a minimum volume flow of 25 % of the nominal volume flow
(EN 378-1).
• Prevent entry into places (e.g., basements, waste water system, ...) where
accumulation could be dangerous.
• Observe scheduled maintenance intervals and record them in the service
booklet for refrigeration plants.
WARNING
Danger to life due to harmful substances
In conjunction with an open flame, refrigerants and compressor oils develop toxic
substances that are harmful to health.
• Do not smoke in the machinery compartment.
WARNING
Danger to life due to suffocation!
When opening the piping during preparation for the brazing process, there is a risk of
suffocation due to the escape of refrigerant or compressor oil.
• In case of a refrigerant leak, enter the machinery compartment only using
heavy-duty respiratory protective equipment.
