1) Based on the operation of the equipment and the needs of the customers, various routine inspections are carried out in a planned manner. 2) In order to ensure more efficient use of the evaporative cooling unit efficiency, please use this product under the following conditions. a) Ambient temperature: 18 ° C - 45 ° C. b) Ambient relative humidity: ≤ 85%. c) Atmospheric pressure: 86Kpa-106Kpa. d) The water supply needs to be softened, the water supply temperature is ≤45°C, and the water supply pressure is 0.15-0.6Mpa. e) The voltage deviation does not exceed ±10% of the rated voltage. f) The ambient air quality should meet the GB 3096 Level 3 (including Level 3) standard. g) Non-corrosive environment. 3) This product is flammable. Please do not approach the fire during transportation, installation and operation. 4) Please pay attention to whether the inlet pipe and the drain pipe are connected well before use, otherwise the leakage may cause damage to other equipment or products. 5) In order to ensure the best effect of the machine, it should be ensured that there are doors or windows that are open enough. If there are not enough open doors or windows, you can load the blinds or install other mechanical ventilation equipment. 6) During the operation of the machine, do not disassemble the engine parts such as the evaporator and the top cover. If the machine needs to be repaired or maintained, the power should be cut off first, otherwise the machine may be damaged or human casualties may occur. 7) Check the condition of the motor during installation. Do not use fuses or other wires with incorrect capacity. 8) In order to ensure the cooling effect, the filter may be considered in areas where the air is more turbid. 9) For places with strict requirements on humidity and temperature, consult a professional for guidance. 10) If the product has any abnormal conditions during the operation, please inform the company or the distribution service point for maintenance. Preventive maintenance 1), pre-season maintenance. Before the start of the season, check the perimeter of the unit and the air inlet for obstructions. 2), the unit is used for maintenance.

The unit is operated for 1-2 months. If the curtain is wet, the filter is clogged or the site is too dirty, it should be cleaned in time to avoid malfunction or affect the operation of the machine. 4), the end of the season maintenance. In order to prevent freezing damage to the body and mosquito breeding, when the water is turned off for a long time, turn off the tap water, then press the cleaning button to clear the water and cut off the power. 5), the inside of the unit is clean. If the unit is running for a long time, in order to ensure the cooling effect, the machine must be cleaned once every 1 or 2 months. Please refer to the instruction manual for detailed disassembly cleaning methods.
