Before You Order And Use<\/div>\n

Before You Order And Use<\/h2>\n

A\/C and refrigeration service can involve high pressure, refrigerant gas, toxic gases, and electrical environments. Confirm pressure range, hose suitability, refrigerant type, and working conditions before using LM70.<\/p>\n <\/div>\n

\n
\n

Confirm Rated Pressure<\/h3>\n

Before testing, confirm the rated pressure of the device under test. Do not use LM70 if the test pressure exceeds its rated range.<\/p>\n <\/article>\n

\n

Check Hose Suitability<\/h3>\n

If the included filling hose does not meet your pressure requirement, use a suitable substitute hose for testing.<\/p>\n <\/article>\n

\n

Confirm Refrigerant Type<\/h3>\n

Confirm the refrigerant type before service and select the correct refrigerant data before diagnosis, charging, or system debugging.<\/p>\n <\/article>\n

\n

Avoid Risky Environments<\/h3>\n

Do not use or store the instrument in high-temperature, high-humidity, flammable, explosive, or strong electromagnetic environments.<\/p>\n <\/article>\n

\n

Use PPE And Ventilation<\/h3>\n

Wear proper protective equipment and use the instrument in a well-ventilated area to reduce refrigerant and toxic gas exposure risks.<\/p>\n <\/article>\n

\n

Do Not Modify Circuitry<\/h3>\n

Do not modify the internal circuitry of the instrument. Unauthorized modification may cause equipment damage or safety risks.<\/p>\n <\/article>\n <\/div>\n
