1. Do not place in places where the sun, rain, wind or relative humidity is greater than 85%. Do not place in an environment with excessive dust, corrosive or flammable gases. Do not place in a place where there is vibration or condensation. Do not get too close to the wall to avoid poor ventilation. It must be used in an environment with corrosive gas, and a desiccator with a copper tube or a stainless steel heat exchanger type dryer should be used. It should be used at an ambient temperature of 40 degrees Celsius or less. 2. Do not connect the inlet of compressed air. To facilitate maintenance, a bypass line should be provided to ensure maintenance space. To prevent the vibration of the screw air compressor from being transmitted to the dryer, the weight of the piping should not be directly applied to the dryer. 3. Do not stand up the drain pipe, do not fold or crush. 4. The power supply voltage is allowed to fluctuate less than plus or minus 10%. A properly designed leakage circuit breaker should be provided. Must be grounded before use, 5, the compressed air inlet temperature is too high, the ambient temperature is too high (above 40 degrees Celsius), the flow rate exceeds the rated treated air volume, the voltage fluctuation exceeds plus or minus 10%, and the ventilation is too bad (the air is also ventilated in winter, Otherwise, the room temperature will rise.) Under such circumstances, the BAUER circuit will function, the indicator light will be off, and the operation will stop. 6. When the air pressure is higher than 0.15mpa, the drain of the normally open automatic drainer can be closed. The displacement of the screw air compressor is too small, the drain port is open, and air is blown out. 7, the compressed air quality is poor, such as mixed with dust and oil, these impurities will adhere to the heat exchanger, reducing its working efficiency, while the drainage is also easy to fail. It is desirable 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 once a month with a vacuum cleaner. 9. Turn on the power. After the running state is stable, turn on the compressed air. After stopping the operation, you must wait for more than 3 minutes before starting again. 10. If using an automatic drainer, always check that the drain function is normal. Always clean the dust on the condenser, etc. Always check the pressure of the refrigerant to determine if the refrigerant leaks and if the capacity of the dryer changes. Check to see if the temperature at which the condensate is removed is normal.
