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. For this reason, never separate any line connections, and always have service and repair work done only by a John Deere dealer who has the appropriate recovery and recycling equipment.

Check the refrigerant level every 200 to 300 hours. With the engine running and the air conditioning system controls set for maximum cooling, check the sight glass (A) at the receiver-drier (B).

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