D Avoid you direct contact to liquid refrigerant.
D Do not heat refrigerant container higher than 40_C (104_F).
D Do not discharge refrigerant into atmosphere.
D Do not allow liquid refrigerant to touch bright metals. Refrigerant combined with moisture is corrosive and will
tarnish surfaces of bright metals including chrome.

amount added to the system.
REFRIGERANT RECOVERY
When discharging refrigerant out of A/C system, always recover it by using refrigerant recovery and recycling
equipment. Discharging refrigerant HFC-134a (R-134a) into atmosphere would cause adverse effect to environ-
ments.
NOTE:
When handling recovery and recycling equipment, be sure to follow the instruction manual for the equip-
ment.
REFRIGERANT CHARGE
Charge a proper amount of refrigerant to A/C system according to charging procedure described in recovery, evac-
uation and charging.
CAUTION:
Do not perform an additional refrigerant charging to A/C system. This cause it to overcharge.
