When the aluminum alloy ceiling air grill is installed, carefully check the cabinet. The unintended household items and objects in the shell should be coated with a little grease or mechanical oil on a part of the connecting surface. The joint surface of the alloy tuyere fan and the foundation should be mobilized when the air inlet and outlet pipes are connected to adapt naturally. No forced connection is allowed, and the gross weight of the pipe should not be added to the prefabricated components of the fan, and pay attention to the quality of the fan.
After setting up the aluminum alloy air grills, test whether the transmission group is normal, and make sure that there will be no problems such as over-tightness and fixed local overlap and bumps. If you find the problem, you can adjust it to the top state immediately.
