3.2  Important information on the use of hydrocarbons

Hydrocarbons (combustible refrigerants) may be used in the compressors named in the title only if all 
relevant and applicable regulations, standards and technical rules are followed.  National safety regu

-

lations must be observed. In addition, we refer to the following applicable standards and regulations: 
EN 378, BGR500, TRBS 2152, EC Directives 1999/92/EC and 2014/34/EU.
The  compressor  and  the  refrigeration  system  must  be  permanently  equipped  with  clear,  identical 
labels/plates (ISO3864) that state that combustible refrigerants are used. This warning plate must be 
unremovably attached to the compressor. 
A hazard analysis in accordance with the Operational Safety Ordinance must be performed for the 
set-up location. Use and handling of the refrigeration system and compressor are to be governed in 
the explosion protection document.
Installation, placement into operation, service and repair (as permitted by the manufacturer) may only 
be performed by personnel who have been specially trained on combustible refrigerants.
If the compressor has to be removed from the system for inspection/maintenance/repair, the remaining 
refrigerant must be suctioned out and the compressor evacuated, filled with nitrogen (< 0.5 bar) and 
closed gas-tight. The compressor must be equipped with a tag that clearly states that the compressor 
was operated with combustible refrigerant (name the refrigerant).
If the system contains combustible refrigerants or residues, extreme caution must be exercised when 
working on the compressor due to the danger of explosion.  This applies especially for the use of fire, open 
flame or other ignition sources (e.g. electronic devices, mobile telephones, static charges, sparks, ...).
During maintenance and repair, it must be noted that hydrocarbon residues may remain dissolved in 
the oil. In addition used dryers contain bottoms of the inflammable refrigerants. Flush the dryer with 
nitrogen and supply it to the recycling.
It should be noted that the solubility of hydrocarbons in oil can be very high, especially at high suction 
pressures. A high-viscosity lubricant may be required, depending on the application and experience.  
The lubricant must be released for use by GEA. Depending on the application, a pump-down switch 
should also be added (e.g. when the refrigeration system is set up outside).

 3.1  Approved  refrigerant

Used refrigerants have to have a self-ignition temperature of 
> 250 °C.
