How to Use an AC Recovery Machine in Summer
Apr
Summer is just around the corner! Have you had car owners visit your workshop complaining that the air conditioning is blowing hot on one side and cold on the other? This means the vehicle needs to add more refrigerant. Congratulations on getting a new business. Still struggling with refrigerant recovery, pipeline leaks, or accurately measuring the amount of refrigerant to refill? We will explore everything you need to know about the freon recovery machine and provide valuable insights into the machine itself and its role in maintaining optimal cooling performance in vehicles.
1.What is the function of a AC recovery machine?
A freon recovery machine is not just a tool for adding refrigerant—it integrates multiple functions such as recovery, vacuuming, inspection, and filtration. It helps technicians perform air conditioning system maintenance more efficiently and safely. If you run an automotive repair-related business, having a freon recovery machine can significantly improve your work efficiency and ensure the quality of air conditioning maintenance.
2.Benefits of Using an AC Recovery Machine.
Using a refrigerant charging machine offers many benefits to both auto repair shops and vehicle owners. Let’s take a look at its advantages:
1.Environmental Responsibility: By using an AC recovery machine, harmful refrigerants can be prevented from being released into the atmosphere. The machine also allows for the secondary cleaning and filtration of refrigerants, ensuring that even refrigerants containing impurities can be purified and reused. This further reduces refrigerant waste and helps comply with environmental standards.
2.Increased Efficiency: Traditional refrigerant charging machines typically take 1-2 hours to complete a refrigerant replacement, but the AUTOOL LM708 uses a high-power vacuum pump to complete the process in just 20-30 minutes. This not only improves cooling performance but also increases efficiency in auto repair shops, saving time and costs.
3.Extended System Lifespan: Regular maintenance with an AC recovery machine helps extend the lifespan of the air conditioning system. By removing debris and contaminants, these machines can prevent premature wear, reducing the likelihood of system failures and costly repairs.
3.Frequently Asked Questions About AC Recovery Machine.
Q1.How much time does the LM708 take to complete a full vehicle refrigerant fillng?
Answer: Most machines on the market are equipped with low-power vacuum pumps and typically require 1-2 hours to complete refrigerant charging.
The LM708’s high-power vacuum pump evacuates the system in about 15-20 minutes, and the refrigerant filling process takes only 5-10 minutes. The entire process completes in just 30-40 minutes.
Q2. How to update the software of the LM707/708?
Answer: Machines purchased after 2024 are the latest models, and the system is already updated to the newest version. New vehicle models will be added over time. After updates, we will notify customers who have purchased the LM707/708 from the official online store.
Q3.How many compressors have each machine?
Answer: The AUTOOL LM708 comes with a built-in air compressor, so there is no need to connect an external air component.
Q4.How do you avoid contamination or mixing of gases?
Answer: If switching refrigerants, it is recommended to clean the pipelines before connecting to the vehicle.
Q5.Do you use two separate sets of hoses?
Answer: It is best to use two sets of hoses. If they are shared, just like the equipment, they should be cleaned before switching.
Q6.What is the frequency for changing the vacuum pump oil, and what oil should I use?
Answer: The machine comes with a visible window to easily check if the vacuum pump oil is within the proper range. If the oil level is below the range, you must add more oil. We recommend purchasing professional vacuum pump oil from Amazon.
Q7.How to clean the hoses of the LM708?
Answer: 1.Use the refrigerant of the operating system to flush the common pipes and components, then recover the refrigerant and discharge to clean the residual oil in the pipes.
2.Run the system to perform a deep vacuum.
3.Switch to the repair quick-connect and complete the system switch.
Q8.Refrigerant filter replacement
Answer: ⚠️ You should replace the drying filter after recovering every 100kg of refrigerant.
- For the new model LM708, after replacing the filter, you need to reset it on the equipment’s interface. If the equipment does not prompt, you can simply enter the universal password 8609 to complete the operation.
- For the older LM708 models, you will need to contact online support to input the verification password in real-time for filter replacement.
Q9.To determine whether you have purchased the new or old version, please refer to the images of the filter: Image 1 – new version; Image 2- old version
