1. The heat exchanger should not be deformed, and the fasteners should not be loose or other mechanical damage.
2. When hoisting the equipment, the hoisting rope must not be hung on the receiver, positioning beam or plate.
3. Leave enough space around the heat exchanger for easy maintenance.
4. The installation of the hot and cold medium inlet and outlet pipes should be connected in the direction specified on the factory nameplate.
5. The pipes connected to the heat exchanger should be cleaned to prevent sundries such as sandstone welding slag from entering the heat exchanger and causing blockage.
6. The heat exchanger shall be hydrostatically tested at 1.5 times the maximum working pressure. The steam part shall not be lower than the steam supply pressure plus 0.3 MPa; the hot water part shall not be lower than 0.4 MPa.
