6) Refrigerant Charging
R equired equipment: B ombe, R 600a refrigerant (67g)
ppliances and heating source for performing work when charging scaled refrigerant. (Do not spray
refrigerant indoor.)
Measure the accurate quantity (67g) of refrigerant to charge it into a B ombe.
Make the B omber as vacuum status to charge refrigerant.
ooling cycle.)
P lease manage refrigerant quantity as 67 134a, R 600 ooling performance
depending on change of refrigerant quantity.
R efrigerant quantity = Weight after charging - Weight before charging (weight of vacuumed B ombe)
C onnect B ombe with a charging tube to charge refrigerant.
Turn on power of refrigerator to operate a compressor.
Measure B ombe weight after 5 through 10 minutes to check remained refrigerant quantity to complete charging of
refrigerant.

7) Leak Inspection and Cycle Check
R equired equipment: Leakage checking machine (foam and leakage inspection machine)
C heck for leakage by using form or a leakage inspection machine at the worked part if charging of refrigerant is
completed.
C heck for leakage at the low pressure part with the compressor stopped, and check at the high pressure part with the
compressor being operating.
If leakage is detected, proceed to repair according to repair process again starting from “2-1. R eturnof R efrigerator
R efrigerant”.
