SYSTEM
HINT:
At the time of installation, please refer to the following item.
Evacuate air from refrigeration system.
Charge system with refrigerant and inspect for leakage of refrig-
erant.
Specified amount: 500 ± 50 g (17.64 ± 1.76 oz.)
3. DRAIN ENGINE COOLANT FROM RADIATOR
HINT:
It is not necessary to drain out all coolant.
4. DISCONNECT LIQUID TUBE AND SUCTION HOSE
(a) Using SST, remove the 2 piping clamps.
SST 09870±00015 (Suction tube)
09870±00025 (Liquid tube)
(1) Insert SST to piping clamp.
HINT:
Confirm the direction of the piping clamp claw and SST using
the illustration showing 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.
