Air Conditioning System

Air Conditioning:

The air conditioning system on this machine contains the fluorinated greenhouse gas refrigerant R134a or R1234yf (Europe) (Global Warming Potential = 1430). See label or instruction manual for gas refrigerant identification. The system contains 0.75 kg (1.65 lb), 0.90 kg (1.98 lb) or 1.0 kg (2.20 lb) of refrigerant which has a CO2 equivalent of 1.430 metric tonnes (1.576 tons) for R134a and 0.001 tonnes (0.001 tons) for R1234yf (Europe).

Sound

Operator Sound Pressure (ISO 6396:2008):

76dB(A)

Average Exterior Sound Pressure (ISO 6395:2008):

97dB(A)

Note:

*The declared dynamic operator sound pressure levels per ISO 6396:2008. The measurements were conducted with the cab doors and windows closed. **The labeled sound power level for the CE marked configurations when measured according to the test procedure and conditions specified in 2000/14/EC.
