NO TICE
Do not use unqualified refrigerant. Huawei will not be liable for any equipment
damage caused by unqualified refrigerant.
Customers can purchase this material from Huawei or other vendors. Verify that
the refrigerant is authentic in the following ways:
1. Dial the refrigerant manufacturer's hotline to confirm the refrigerant
authenticity.
2. Place the refrigerant tank indoors for 24 hours. Use a point thermometer to
measure the outer surface temperature of the refrigerant tank, and connect a
pressure gauge to the tank to measure the internal pressure, as shown in
. Find the saturation pressure corresponding to the measured
outer surface temperature from
. If the deviation between the
saturation pressure and the measured internal is greater than 0.2 MPa, the
refrigerant does not meet the requirements, and needs to be replaced.
