First of all, the installation environment of the refrigeration dryer must be checked before installation. It should not be placed in a place where the relative humidity is greater than 85%, or where the relative humidity is greater than 85%, or where there is much dust, corrosive or flammable gas. It should not be placed in a place where there is vibration or freezing of condensed water, and it should not be too close to the wall to avoid poor ventilation.

1. When it is necessary to use it in an environment with corrosive gas, a dryer with rust-proof copper tube or a stainless steel heat exchanger type dryer should be used. At the same time, the ambient temperature should be used below 40℃.
 
2. Do not connect the compressed air inlet wrongly. In order to facilitate maintenance, a bypass pipeline should be provided to ensure a maintenance space. It is necessary to prevent the vibration of the air compressor from being transmitted to the dryer. Do not add the weight of the piping directly to the dryer.
 
3. Do not stand the drain pipe upwards, do not fold or squash it.
 
4. The allowable fluctuation of the power supply voltage is less than ±10%. An appropriate capacity leakage circuit breaker should be provided. Must be grounded before use.

5. The temperature of the compressed air inlet is too high, the ambient temperature is too high (above 40℃), the use flow exceeds the rated processing air volume, the voltage fluctuation exceeds ±10%, and the ventilation is too poor (please change the air in winter, otherwise the room temperature will also increase ), etc., the protection circuit will work, the indicator light will be off, and the operation will stop.

6. When the air pressure is higher than 0.15MPa, the drain port of the normally open automatic drain can be closed. The displacement of the air compressor is too small, the drain is open, and air is blown out.

7. The quality of compressed air is poor. If dust and oil are mixed, these stolen goods will stick to the heat exchanger, reducing its work efficiency, and the drainage is also prone to failure. It is hoped to install a filter at the inlet of the dryer, and to confirm that the drainage is not less than once a day.

8. The vent of the dryer should be cleaned with a vacuum cleaner once a month.

9. Turn on the power supply, and then turn on the compressed air after the running state is stable. After stopping the operation, you must wait for more than 3 minutes before restarting.

10. If you use an automatic drain, you should always check whether its drainage function is normal.
