What should I do if the outdoor unit of the central air conditioner in the shopping mall is installed near the entrance of the community?

If the outdoor unit of the central air conditioner in the shopping mall is installed near the entrance of the community, it will be very noisy and the airflow will become very bad. It is suggested to communicate with the residential property to change the location.

When installing the air conditioner, please pay attention to the following items:

1. Prepare the required welding equipment, suitable fittings and air conditioning copper pipes.

2. Be sure to clean the fittings to be welded and the air conditioning copper pipe to ensure the correct solder joints.

3. Mark the air-conditioning copper tube to be cut, and cut the air-conditioning copper tube with a copper knife.

4. Clean both ends of air conditioning copper tube with emery cloth or gauze until it looks clean. This is done to remove dirt and grease and prevent oxidation.

5. Use air-conditioning copper tube flux when welding, and only use a thin layer of air-conditioning copper tube flux.

6. When heating the air-conditioning copper tube and fittings, the fittings in the tube will need more heat, so the fittings and air-conditioning copper tube should be hot enough when installing.
