    检查过滤器是否堵塞，清洁或更换过滤器。  
     Check if filters are clogged, clean or replace them.  
    检查风机是否正常运行，必要时维修或更换风机。  
     Check if the fan is operating normally, repair or replace if necessary.

2. 冷却效果差 (Poor Cooling Performance):  
    检查蒸发器是否脏污，进行清洗。  
     Check if the evaporator is dirty and clean it.  
    检查制冷剂是否充足，必要时补充制冷剂。  
     Check refrigerant levels and replenish if necessary.

3. 设备噪音过大 (Excessive Noise):  
    检查风机轴承是否磨损，更换轴承。  
     Check if fan bearings are worn and replace them.  
    检查涂装设备安装是否稳固，加固安装支架。  
     Check if the equipment is securely installed and reinforce the mounting brackets.

4. 电气故障 (Electrical Faults):  
    检查电源电压是否稳定，确保符合设备要求。  
     Check if the power supply voltage is stable and meets equipment requirements.  
    检查控制电路是否正常，修复或更换故障部件。  
     Inspect the control circuit and repair or replace faulty components.

4. 安全注意事项 (Safety Precautions)  
1. 断电操作 (Power Off Before Maintenance):  
    在进行任何维护或维修前，务必断开电源。  
     Always disconnect power before performing any maintenance or repairs.

2. 佩戴防护装备 (Wear Protective Gear):  
    清洁或维修时，佩戴手套、口罩和护目镜。  
     Wear gloves, masks, and goggles during cleaning or repairs.

3. 专业维修 (Professional Repair):  
    对于复杂故障，建议联系专业技术人员处理。  
     For complex faults, it is recommended to contact professional technicians.
