Answer: (1) Turn on the air switch and the power indicator light POWER (red light) will light up.
(2) At this time, press the green button START and the time relay will work. After a delay of 3 minutes, the contactor will be energized, the operation indicator light RUN (green light) will light up, and the compressor will start to run.
(3) Check whether the compressor is running normally and whether the high and low pressure gauges of the refrigerant are normal.
(4) If everything is normal, open the air compressor or the inlet and outlet valves to supply air to the dryer and close the air bypass valve. At this time, the air pressure gauge will indicate the air outlet pressure.
(5) After observing for 5 to 10 minutes, the air treated by the dryer meets the use requirements. At this time, the low pressure gauge of the refrigerant is only in the range of 0.3 to 0.5 MPa, the high pressure gauge of the refrigerant is in the range of 1.2 to 1.6 MPa, and the dew point temperature is between 2 and 10 °C.
(6) Open the ball valve on the automatic drainer to allow the condensed water in the air to flow into the drainer and be discharged out of the machine through it.
(7) Avoid running the dryer for a long time without load.
(8) After stopping the dryer, wait at least 3 minutes before restarting it to avoid continuous switching.
