8. When testing for a leak at the compressor, move the probe
along the compressor body joints, along the pressure relief
valve and any switches, the all around the compressor shaft
seal area. Shaft seal normally leak during compressor
operation so it may be very difficult to ascertain if a leak exists
because the testing with an electronic leak detector is
performed with the system off. However, any indication from
the LDA1000H in a setting below the 14 g / yr. (0.5 oz / yr.) may
be an indication that a significant leak has been found,
especially if no other leaks have been located.
9. Following any service to the refrigerant system, and any other
service that disturbs the refrigerant system, a leak test of the
repair and of the service ports of the refrigerant system should
be done.
