1. Check the integrity of the radiator before installation, and unscrew the pipe buckle and plug.　　
2. The connection pipes (water pipe and steam pipe) connecting the radiator should be the same size as the inlet and outlet pipe joints of the radiator, and the radiator cannot be supported by the connection pipe.　　
3. The air heat exchanger shall be equipped with corresponding heat medium piping system according to the architectural design. Note that gate valves should be installed on the steam or hot water pipeline and on the return water pipeline; when heating with steam, a condensate drain should be installed on the condensate pipeline. When several radiators are used in combination, each of them can individually control its steam inlet, discharge and return pipe devices, especially when the air is used in series in the air flow.　　
4. When the air inlet pipeline of the air heat exchanger is directly connected to the outdoors, a blocking device should be installed at the air inlet to prevent the radiator from being frozen when it stops working.　　
5. When the air heat exchanger uses steam as the heat medium:
a. The inlet end of the steam inlet is the end of a finned tube with shrinkage holes, please see clearly before installation.
b. A steam trap should be installed at the end of the return water pipe. The drainage volume of the steam trap should exceed 3 to 4 times of the condensed water volume of the radiator.
c. Steam is introduced about ten minutes before the fan starts, which is the preheating of the air heat exchanger to prevent the steam from suddenly entering the cold air heat exchanger to generate a large amount of condensate and impact the equipment.
