Answer: (1) Check whether the power supply voltage is normal.
(2) Observe the refrigeration system and the high and low pressure gauges of the refrigerant. The two gauges reach a basic balance under a certain pressure, and this balance force fluctuates up and down according to the ambient temperature, generally around 0.5~1.0MPa.
(3) Check whether the air pipeline is normal. The air inlet pressure shall not exceed 1.0MPa, and the upper limit of the inlet temperature is 45℃.
(4) Check whether the cooling water is normal. The water pressure is 0.2~0.4MPa, the water temperature is ≤32℃, and the cooling water inlet valve is opened.
(5) The compressed air pipe system must be purged before starting to prevent debris from entering the dryer and filter and affecting the use.
