8.2 Removal of Refrigeration System Components
• Before replacing any refrigeration cycle component, recover the refrigerant using
standard recovery procedures and equipment.
• When recovering the refrigerant, use the pinch-off tubes at the low pressure side (tube 1)
and high pressure side (tube 2) as shown in the figure below.
CAUTION
• To prevent oxidation, dry nitrogen should be conducted {flow rate 0.27 gal/min (1 L/min)} through
the pinch-off tube during any brazing operation.
• During any component replacement involving brazing, shield nearby parts with a steel plate, etc.,
to protect them from the flame.
When replacing the compressor, attach the pipe 1 and the pipe 2 packaged in the compressor
assembly.
