3 - HANDLING INSTRUCTIONS
Refrigerant handling
1.Do not misidentify refrigerants
If an HFC-134a (or HFO-1234yf) air conditioning
system is mistakenly charged with another
refrigerant, serious problems such as compressor
seizure may occur. Therefore, confirm before
charging with refrigerant that the type of air
conditioning system is an HFC-134a (or
HFO-1234yf) system.
2.
Do not release refrigerant into the air
Although HFC-134a (or HFO-1234yf) is not
subject to CFC regulations, it can have effect on
global warming and so should not be released
into the air. When removing refrigerant from the
air conditioner system, always use a refrigerant
recovery unit made especially for HFC-134a (or
HFO-1234yf).
Compressor handling
Do not strike or unnecessarily turn the compressor
upside down. If the compressor is knocked over or
turned upside down during handling or installation,
rotate the armature plate 5 or 6 times by hand to
circulate the oil. Otherwise, oil in the cylinder
during compressor start-up will cause valve
damage and reduce durability.
WARNING!
Direct contact with refrigerant can cause
frostbite or blindness.
Always wear safety glasses and protective
gloves.
Do not work with refrigerant close to your face.
