1. Keep the pipe network clean. The pipe network must be cleaned before or after work. The purpose of this is to avoid blockage of the heat exchanger. Also pay attention to timely cleaning of the decontamination device and filter, so that the entire work can be completed smoothly. 2. Strictly control softened water . It is very important to check the water quality. Under the premise of the water quality treatment of the softened water, the water in the system and the water quality of the softening tank must be carefully checked, and the injection treatment can be carried out after it is determined to be qualified. 3. New system inspection. For some new systems, it cannot be used alternately with the heat exchanger immediately. First, the new system needs to be operated for a specified period of time, so that it has an operating mode, then the heat exchanger can be incorporated into the system. The purpose of this is to avoid impurities in the pipe network from damaging the heat exchanger equipment.
