AUTOOL LM Series<\/div>\n

Product Overview<\/h2>\n

The AUTOOL Refrigerant Recovery Machine is designed for professional automotive A\/C service, including refrigerant recovery, evacuation, charging, leak detection, refrigerant purification, and service reporting. LM707 is built for R134a refrigerant service, while LM708 supports both R134a and HFO-1234yf for modern high-end vehicles, petrol vehicles, hybrid vehicles, and electric vehicles when the refrigerant type matches the vehicle requirement.<\/p>\n

The system uses deep internal vacuum technology to limit refrigerant loss to under 50g when switching between different refrigerants and helps reduce cross-contamination risk. LM708 is equipped with dual refrigerant tanks to reduce frequent tank changes, while quick weighing-sensor unlocking, self-diagnostic capability, and USB upgrade support help make maintenance more convenient and cost-effective.<\/p>\n

The functions of different models vary slightly. For details, please refer to the individual LM series product links.<\/em><\/strong><\/p>\n <\/div>\n

\n
\n

Dual-System Refrigerant Service<\/h3>\n

LM708 supports both R134a and HFO-1234yf refrigerants for automotive A\/C maintenance. LM707 supports R134a refrigerant only.<\/p>\n <\/article>\n

\n

Fully Automated Operation<\/h3>\n

After presetting parameters, the refrigerant recovery tool automatically completes recovery, evacuation, charging, and leak detection.<\/p>\n <\/article>\n

\n

Deep Internal Vacuum Technology<\/h3>\n

Helps limit refrigerant loss to under 50g when switching refrigerants and reduces cross-contamination risk between service lines.<\/p>\n <\/article>\n

\n

How It Works<\/div>\n

How It Works<\/h2>\n

The core workflow lies in vacuuming, precise filling, and intelligent control, achieving an efficient, safe, and environmentally responsible refrigerant filling process.<\/p>\n <\/div>\n

\n
\n

Vacuuming<\/h3>\n

The vacuum pump removes air and moisture from the refrigeration system, ensuring no impurities affect the refrigerant filling process.<\/p>\n <\/article>\n

\n

Refrigerant Filling<\/h3>\n

A flow control valve and pressure sensor precisely transfer refrigerant from the storage tank into the refrigeration system according to the preset amount.<\/p>\n <\/article>\n

\n

Smart Monitoring<\/h3>\n

Real-time monitoring of pressure and flow helps prevent overfilling or insufficient filling, with automatic shutoff and alerts for abnormal conditions.<\/p>\n <\/article>\n

\n

Safety Protection<\/h3>\n

Continuous monitoring of temperature and pressure helps prevent refrigerant leakage or overpressure, protecting the equipment and operators.<\/p>\n <\/article>\n <\/div>\n <\/section>\n\n

Maintenance And Care<\/div>\n

Maintenance And Care<\/h2>\n

Filter replacement and reset are critical for LM707 \/ LM708 service reliability. Plan filter purchases before the machine reaches the 100kg refrigerant service cycle.<\/p>\n <\/div>\n

\n
\n

100kg Filter Cycle<\/h3>\n

The new LM707 \/ LM708 automotive refrigerant recovery machine requires filter replacement after every 100kg of refrigerant use.<\/p>\n <\/article>\n

\n

Reset Password 8609<\/h3>\n

After replacement, reset the filter on the device interface. If no prompt appears, enter the universal password \u201c8609\u201d to complete the operation.<\/p>\n <\/article>\n

\n

Inspect Around 140 Vehicles<\/h3>\n

Approximately 600g of refrigerant is used per vehicle. A 100kg supply covers about 166 vehicles, so inspection after 140 vehicles is recommended.<\/p>\n <\/article>\n <\/div>\n
