PRECAUTION
PRECAUTIONS FOR REFRIGERANT HFO-1234yf (R1234yf)
(a) HFO-1234yf (R1234yf) Refrigerant
(1) Always use HFO-1234yf (R1234yf) as the refrigerant.
NOTICE:
HINT:
The shape of the service port for refrigerant charging has an exclusive design conforming to international standards for HFO-1234yf (R1234yf) to prevent improper refrigerant charging.
(b) Compressor Oil
(1) Always use VC100YF as the compressor oil.
(2) When parts of the air conditioning system are removed, quickly block off any areas that are exposed to the outside air with plugs, vinyl tape, etc., as the oil used for HFO-1234yf (R1234yf) systems absorbs moisture easily.
(3) Do not allow the compressor oil to spray, as the oil used for HFO-1234yf (R1234yf) systems has harmful effects on acrylic resins.
(c) Evacuation
(1) When evacuating the system, be sure to use a refrigerant recovery unit, refrigerant recycler and refrigerant charger that are compatible with HFO-1234yf (R1234yf) systems.
(d) Refrigerant Gas Leak Inspection
(1) Use a gas leak detector to check for refrigerant gas leaks.
HINT:
Be sure to use a gas leak detector that is compatible with HFO-1234yf (R1234yf) systems.
(2) Turn the ignition switch off when checking for refrigerant leaks.

PRECAUTIONS RELATED TO REMOVAL AND INSTALLATION OF PARTS
(a) In case refrigerant gets in your eyes
(1) Do not rub your eyes with your hands or a cloth.
(2) Consult an eye doctor.
(b) Handling of Refrigerant (Container)
(1) Do not heat the container. If the container is directly heated or put into boiling water, the pressure inside the container will become abnormally high and the container may burst.
(2) Do not drop or strike the container.
(3) Do not bring the container anywhere near your face. Always wear eye protection.
(c) Pipe Installation
(1) Always use new O-rings.
HINT:
When removing an O-ring, use an object with a soft tip so as not to damage the piping.
(2) Apply a sufficient amount of compressor oil to the O-ring.
(3) Route the hoses in the way they are naturally shaped. Do not twist or forcibly bend the hoses.
(4) Do not use cloth gloves, etc. as fibers attached to O-rings can lead to refrigerant gas leaks.
