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 ● LM-708 is an ideal option for workshops that have requirements of han- dling both R-134a and HFO-1234yf refrigerants. The loss of refrigerant is minimized to less than 50 gram at shifting from one refrigerant to another, and deep internal evacuation ensures zero cross contamination between two refrigerants.
Automatic service reminding. The equipment filter-drier life is designed to desiccate and recycle 100 KG refrigerant. Can be used for fuel, hybrid or electric vehicles. 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.

OPERATIONS INSTRUCTION Unlock ● Remove the two lock bolts, to release load cells of the two tanks, and to load cells make them ready to work. 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 R-134a or HFO-1234yf, and turn on the machine, select “Tank fill” function, set tank fill amount to fill R-134a or HFO-1234yf tank with refrig- erant. ● It is recommended to maintain refrigerant level of both tanks at 4-6kg.
Suction Charge ● When machine is switched on, filter-drier life is displayed. Click OK to enter main menu.

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).
