CAUTIONS General For the correct use of the instrument, please read the full text of this safety manual carefully before use. The storage cylinder in this unit contains liquid refrigerant. Overfilling of the cylinder can cause violent explosion. Do not disable the overfill safety feature.
PRODUCT INTRODUCTION Overview ● LM707 is an ideal option for workshops that have limited equipment investment budget. Even economic, the machine is robustly built, with luxurious features such as color touch screen, amply database and patented oil separator / manifold. The unique design has facilitated quick load cell unlock, easy and economic maintenance (DIY maintenance rec- ommended), self troubleshooting and convenient USB upgrade etc.
Function Recovers and purifies refrigerant from auto- Recovery table motive A/C to equipment tank. Evacuates air and moisture from the A/C Vacuum system. Upon completion of vacuum, manual oil injection is prompted. Charge refrigerant from equipment gas cylinder Charge Main to automotive A/C system.
OPERATIONS INSTRUCTION Unlock ● Remove the bolt that fix tank platform with chassis, to release tank load load cells cell. Warning Failure to remove the load cell lock bolts may cause wrong refrigerant processing amount. When you need transport the machine, please screw those bolts on. ●...
● Through tank fittings, connect either HP or LP hose with external refriger- ant, and turn on the machine, select “Tank fill” function, set tank fill amount to fill tank with refrigerant. ● It is recommended to maintain refrigerant level of tanks at 4-6kg. Air purge It is recommended to purge the air in equipment tanks every day before ●...
Suction ● When machine is switched on, filter-drier life is displayed. Click OK to enter main menu. Total refrigerant recovered: 15.85Kg / 34.76Lb Refrigerant can be recovered till filter-drier change: 84.15Kg / 185.02Lb Change filter-drier ● Main menu. ● Recovery Empty used oil vessel before the recovery function is started.
in the internal refrigerant cylinder. The machine should be left connected on the vehicle for a minimum time of 3 minutes (longer in cold climates) for any pressure increase test. If after 3 minutes (or longer if possible) there is no pressure increase, the recovery can be acknowledged com- pleted.
● The minimum tank fill set value is 0.5kg. ● The maximum tank fill set value is the calculation result of 8kg (80% of tank allowable maximum weight) minus amount of refrigerant the tank contains ( For example, if there is 2kg refrigerant in the equipment tank, the maximum tank set value is 6kg).

● Warning: Misoperation in calibration could bring about serious consequences to equipment or vehicle A/C system. ● Database: Users can access database of refrigerant / oil volume of different car makes and models. ● Unit set: To set metric or American imperial unit. The two numbers displayed in the bottom part of the interface are values of two tank load cells, for load cell diagnosis purpose.
MAIN TROUBLESHOOTING Remarks: Regular maintenance by specialized technicians may largely reduce machine failure. Malfunction Reasons Solution ● ● Insufficient vacuum pump oil. Add oil to central line. ● ● Pump oil emulsion, dirty. Put new oil. ● ● Pump oil inlet plugged. Clean oil inlet.
