Precautions for Use

1.Control the quality and quantity of refrigerant and refrigeration oil: The refrigerant must be R134a that meets the standard. The use of inferior refrigerant is strictly prohibited, otherwise it will corrode the internal components of the compressor and reduce the refrigeration effect. Refrigeration oil should be added in accordance with the specifications. It should neither be too little to cause insufficient lubrication and component wear, nor too much to result in excessive air conditioning pressure and reduced refrigeration efficiency. When replacing the compressor, the corresponding amount of refrigeration oil should be replenished simultaneously to avoid omissions.

2.When replacing, make sure to clean the system and check the accessories: If the compressor needs to be replaced, thoroughly clean the entire system including the air conditioning pipeline and evaporator first. If there is iron powder or blackened impurities in the pipeline, it is recommended to replace the condenser simultaneously. This is because the heat dissipation fins of the condenser are in a parallel structure and are difficult to clean thoroughly. The residual impurities will circulate into the new compressor and cause damage. At the same time, the dryer needs to be replaced to prevent impurities and moisture in the old dryer from affecting the operation of the new compressor.

3.Pay attention to the operating status on a daily basis: If abnormal sounds or vibrations are detected from the compressor during use, or if the cooling effect of the air conditioner suddenly drops, timely maintenance is required. Abnormal noises may be caused by mechanical issues such as internal bearing wear and loose pulleys, while poor cooling may be related to abnormal compressor pressure and refrigerant leakage. Timely troubleshooting can prevent minor faults from escalating into complete compressor damage.

4.Avoid improper operation to increase load: When the vehicle is idling, try to avoid keeping the maximum cooling mode on for a long time. At this time, the engine speed is low and the load on the compressor is relatively large. If this continues for a long time, it will easily increase the burden on the engine and may also cause the compressor to overheat. In addition, do not forcibly turn on the air conditioner when the air conditioning system malfunction (such as pipeline leakage) has not been repaired, to prevent the compressor from running dry and burning out due to lack of refrigerant or insufficient lubrication.

Regular professional maintenance: It is recommended that during the regular vehicle maintenance, the maintenance personnel check the pressure of the air conditioning system and the tension of the compressor belt. If the belt is loose, it should be adjusted in time. At the same time, professional equipment is used to check whether there is any leakage in the system to avoid compressor failure due to system abnormalities in advance.
