R-744 (CO

2

) NOTICE

For Systems Utilizing R-744 (CO

2

) Refrigerant

For refrigeration units that utilize R-744 (CO

2

), pressure relief and pressure-reg-

ulating relief valves may need to be installed based on the system capacity.  The 
valves need to be located such that no stop valve is positioned between the relief 
valves and the parts or section of the system being protected.

When de-energizing refrigeration units containing R-744 (CO

2

), venting of the 

R-744 (CO

2

) refrigerant may occur through the pressure regulating relief valves.  

These valves are located on the refrigeration system and not on the case model.  

If venting does occur, the valve must not be defeated, capped, or altered by any 
means.

WARNING: Under no circumstances should any component be replaced or 
added without consulting Hill PHOENIX Field Service Engineering.  Utilizing 
improper components may result in serious injury to persons or damage to 
the system.
