SUCTION LINE (Continued)
fitting) of the condenser and the mid-line connector
block of the suction and liquid line assembly. The liq-
uid line also contains the variable orifice valve. It
has no serviceable parts except the rubber O-ring
seals used on the fittings at each end of the line. If
the liquid line or the variable orifice valve are dam-
aged or faulty, the liquid line unit must be replaced.
• Suction line - The suction line is a flexible hose
type line that is connected between the mid-line con-
nector block of the suction and liquid line assembly
and the suction port of the compressor. It has no ser-
viceable parts except the rubber O-ring seals used on
the fittings at each end of the line. If the suction line
is damaged or faulty, it must be replaced.
• Suction and liquid line assembly - The suc-
tion and liquid line assembly is a formed tubing type
line assembly that includes the mid-line connector
block, a connector block for the evaporator, inlet and
outlet line fittings for the accumulator and both A/C
service ports (Fig. 8). The A/C service port caps, the
A/C service port valve cores, the gasket used to seal
the connector block at the evaporator and the rubber
O-ring seals for the line fittings at the accumulator
are all available for service replacement. If any other
part of the suction and liquid line assembly is dam-
aged or faulty, the assembly must be replaced.

High pressures are produced in the refrigerant sys-
tem when the air conditioning compressor is operating.
Extreme care must be exercised to make sure that each
of the refrigerant line connections is pressure-tight and
leak free. It is a good practice to inspect all flexible hose
refrigerant lines at least once a year to make sure they
are in good condition and properly routed.
