The A/C refrigerant system is a clutch cycling orifice tube type. The system components are: 

z

A/C compressor (19703)  

z

A/C condenser core (19712)  

z

A/C evaporator core (19860)

z

suction accumulator (19C836)  

z

connecting refrigerant lines  

The refrigeration system operation is controlled by the following: 

z

A/C evaporator core orifice (19D990)  

z

A/C cycling switch (19E561)  

z

A/C pressure cutoff switch (19D594)  

The refrigerant system incorporates an A/C compressor controlled by an A/C cycling switch. The A/C cycling 
switch senses pressure in the suction accumulator to control operation of the A/C compressor (19703). 

An A/C compressor pressure relief valve (19D644) is installed in the A/C manifold and tube (19D734) to 
protect the compressor against excessively high refrigerant pressures. An A/C evaporator core orifice is 
installed to the condenser to evaporator tube (19835) to meter the liquid refrigerant into the A/C evaporator 
core.
