leaks of the refrigerant.
Specified amount: 1,050 ± 50 g (37.03 ± 1.76 oz.)
2. DISCONNECT LIQUID AND SUCTION TUBES
(a) Using SST, remove the 2 piping clamps.
SST 09870-00025 (Liquid tube)
09870-00015 (Suction tube)
(1) Insert SST to piping clamp.
HINT:
Confirm the direction of the piping clamp claw and SST referring
to the illustration on the caution label.
(2) Push down SST and release the clamp lock.
NOTICE:
Be careful not to deform the tubes when pushing SST.
(3) Pull SST slightly and push the release lever, then re-
move the piping clamp with SST.
(4) Remove the piping clamp from SST.
(b) Disconnect the both tubes.
NOTICE:
Cap the open fittings immediately to keep moisture or dirt
out of the system.
HINT:
At the time of installation:
Lubricate 4 new O-rings with compressor oil and install
them to the tubes.
After connection, check the fitting for claw of the piping
clamp.
