Checking Refrigerant Level

IMPORTANT: The air conditioning system operates using R134a refrigerant (tetrafluorethane). This substance does not contain any chlorine atoms, so it does not have a detrimental effect on the ozone in the Earth's atmosphere.

Even so, the refrigerant must never be discharged straight into the air. It must be trapped in a recycling unit. Therefore do not separate any line connections and have service and repair work done only by your John Deere dealer having appropriate recovery or recycling equipment available.

Check refrigerant level every 100 hours. With air conditioning system controls set for maximum cooling and engine running, check sight glass (A) at receiver-dryer (B).

If refrigerant appears cloudy or foamy, refrigerant level is low and system should be recharged by your John Deere dealer.
