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.
