Since the pressure of new refrigerant R410A is 1.4 times that of traditional refrigerant, its performance
is susceptible to impurities like moisture, scale and grease, etc. It's essential to remove the moisture,
dust, other refrigerants or refrigerant oils from the refrigeration system. Hence, the failure to use
specified materials and tools may result in explosion, personal injury, refrigerant leakage, electrical
failure or fire.
DANGER
Note: When in immediate contact with refrigerant, please use the installation tools and instruments
dedicated to the new refrigerant.
