Refrigerant R410A Do not use inferior refrigerant. Otherwise, Huawei has no responsibility for the damage caused by the inferior refrigerant. Refrigerant authenticity verification method: 1. Dial the hotline of the refrigerant producer to confirm its reliability. 2. Put the refrigerant indoor for 24 hours. Then use a thermometer to measure the external surface temperature of the refrigerant cylinder (figure 1) , and connect a pressure gauge to the cylinder to measure its internal pressure (figure 2) .
Cooling water side needle valve 1. If they do not exist, contact Huawei technical support. 2. Connect the hose to the pressure gauge, and tighten all pressure gauge valves. 3. Remove the needle valve bonnet, and connect the other end of the hose to the needle valve.
