Ask the site engineering personnel to prepare and install pipe supports. For details about the pipe support
requirements, see Pipe Support in 3.7.1 Materials.
Step 2 Route pipes inside the cabinet. For details, see 3.7.6.1 Laying Out Pipes Inside a Cabinet.
Step 3 Connect the indoor unit stop valve.
Connect the liquid pipe stop valve first, and then the gas pipe stop valve.
1. Remove the black plastic nut from the liquid pipe stop valve using an adjustable wrench.
Check that the PTFE washer on the stop valve and the inner protruding surface of the
active connector nut are free of impurities and scratches.
Clean up impurities using alcohol or a wet cloth. For any scratch, contact Huawei
technical support for replacement.
2. Hold the copper pipe after the pipe nut with one hand and keep the pipe nut and the stop
valve screw thread on the same center line. Secure the pipe nut to the stop valve with the
other hand and tighten the nut using a torque wrench, as shown in Figure 3-62.
