Special NOTE:
GAW14L's only come with 1# of R-407c from the factory. Because of this, do NOT add the initial charge (R-407c) into the suction side. The large amount of initial charge in the suction line WILL slug the compressor at start-up and cause damage. Weigh in a "lower-than-total-expected" (about 2/3rds the total) amount into the liquid side first, then add needed remainder after start-up.
