SERVICING
(2.1 Outdoor Unit)
(9) Remove the flare-nut at the compressor side, and disconnect the evacuating oil pipe.
There is a possibility that the oil may flow from the inside of the evacuating oil pipe.
Therefore, prepare an oil pan, etc. to collect the oil.
NOTES:
1. Completely wipe off the oil if the oil is spread to the other parts such as the compressor cover,
wiring, bottom base, etc. If not, this will cause many problems to the unit.
2. If the oil is spilt, charge new oil equivalent to the spilt oil.
3. Check to ensure that the oil is not foul.
If foul, replace it with new one.
