1. Before installing the radiator, confirm the integrity of the radiator package. When placing it, use the corresponding anti-shock and anti-collision measures. Do not drag the radiator in any way. The radiator should be stored in a dry and rainproof place. 2. The site is cleaned up. The valves, main pipes, branch pipes and pipe supports and hangers of the heating system have been installed and the pipe is flushed and tested according to the design requirements. 3. The external thread of the radiator should meet the requirements of JG/T6-1999. The thread of the branch pipe connected to the radiator should be complete. If there is broken wire or missing wire, it should not be greater than 10% of the full buckle of the thread, and at least the integrity of the year. Thread. 4. The inner wall of the radiator is installed. 5. The body test pressures such as steel radiator, aluminum radiator, copper-aluminum composite radiator and cast iron radiator shall be 1.5 times of the working pressure selected by the design if the design is not required, but the steel plate radiator body is the largest. The test pressure should not exceed 1.3 MPa and not less than 1.3 MPa. The test pressure is 2 to 3 minutes without leakage. 6. Installation steps of the radiator: first install the water inlet valve and the return water valve, measure the position of the radiator with a level gauge for the fixed pendant, place the radiator smoothly, connect the valve connector with the inlet and outlet valves, and measure with the level gauge. Whether the radiator is straight and the pipeline installation meets the requirements. Use a pipe wrench to tighten the fittings. Pressure test: close the main pipe connecting valve, close the inlet and return valve of the radiator, the test pressure should be 1.5 times of the working pressure and test pressure for 2 to 3 minutes without leakage.
