Accumulator Installation Note

Caution

•  Compressor oil has high moisture absorbency so if left for a long time, it absorbs moisture, which may lead to a decrease in A/C performance. Drain and refill the compressor oil within 10 min.

1.  When replacing the accumulator, perform the following procedure.

(1)  Tilt the old accumulator to drain the oil into a clean measuring container through the IN port.

(2)  Return the accumulator to its original posture when the oil no longer comes out.

(3)  Repeat Steps 1 and 2 three or four times until no oil comes out.

(4)  Prepare the same amount of oil (new oil) as the drained oil.

(5)  Add 10 ml {10 cc, 0.34 US fl oz} of new oil to the new oil prepared in Step 4.

(6)  Fill the new accumulator with the oil prepared in Step 5 through the IN port.
