refrigerant or following repairs on system that
necessitated opening of a connector, it is nec-
essary to test for leaks and tighten connectors
or make repairs as required before system is
charged and put in operation* If system has
been discharged for making repair or to elimin-
ate moisture, system must be evacuated before
partially charging for a leak test.

ply in system is very low or where system has
been evacuated.
