CA UTION
Do not use low-quality refrigerant. The supplier is not responsible for any device
damage caused by low-quality refrigerant.
Verify that the R410A refrigerant is authentic in the following ways:
1. Dial the refrigerant vendor's hotline to confirm the refrigerant authenticity.
2. Place the refrigerant in an indoor place with constant temperature and
humidity for 24 hours. Then, use a thermometer to measure the temperature
of the refrigerant cylinder outer surface and connect a pressure gauge to the
pressure tank to measure the internal pressure. Find the saturation pressure
corresponding to the measured external surface temperature from the
mapping table. If the deviation between the saturation pressure and the
measured internal pressure is greater than 0.2 MPa, the refrigerant does not
meet the requirements and needs to be replaced.
