Huawei FusionModule800 Quick Guide

1. Connect the liquid pipe stop valve first, and then the gas pipe stop valve.
2. Tighten the liquid pipe stop valve using a 27# torque wrench to a torque of 35–37 N·m.
Tighten the gas pipe stop valve using a 36# torque wrench to a torque of 50–52 N·m
3. When tightening a stop valve using a torque wrench, secure the hex nut of the active
connector at the welded copper pipe to prevent the copper pipe from turning and further
deforming as the stop valve is being tightened.
4. Ensure that you tighten the valve to the specified torque. The failure torque for the nut of the
liquid pipe stop valve is 70 N·m and that for the nut of the gas pipe stop valve is 100 N·m.
The torque greater than the failure torque will damage the screw thread.
