The refrigerant filling recycling machineas a universal device for car maintenance, should beeasy to operate and lower maintenance workers workload to the highest degreeand recycle cold media as well as protect the environment. If no mechanical,electrical malfunction and no tube leakage is discovered after the cars air conditioning system is checked, new refrigerantshould be replenished.

Attentions of Refrigerant Filling Recycling Machine:

1.The oil plug on the vacuum pump must be replaced before usingrefrigerant filling recycling machine.

2.No high pressure is allowed on the vacuum gauge. Turn off the vacuumgauges V3 before connecting high and low tubes or filling in refrigerant.

3.Turn off the valve with a proper strength. Lessen the torsion force asmuch as possible on the condition that no leakage occurs, which can lengthenthe valves life span. But even if the air-tight part is damaged after along-term use, it is easy to repair and replace it.

4.Only purified refrigerant without solid mixtures can be adopted.

5.Turn off all the valves after the operation is completed.

Repairs and Maintenance of Refrigerant Filling Recycling Machine:

1.Frequently conduct self-examination on the machines system. If slight leakageappears on the turning off valve, do not tighten it with a strong force.Instead, the valve can be dismantled to position the air-tight spot. In mostcases, solid mixtures are stuck to the valves air-tight surface which is madeof ethylene. As long as the solids are removed, the valve can continue itswork. When reassembling the valve, it is advisable to install the valve rodparts one by one into the valves body in a kneading, careful and slow manner.The air-tight loop may be damaged due to a rapid installation.

2.Frequently examine the air-tight cushion of the liquid tube. Replace itimmediately if damage is discovered.

3.The vacuum pump is not allowed to suck air over 3 minute in a row. Ifthe oil is found black, or muddy, replace it as soon as possible. Under normalcircumstances, the oil should be replaced every 1000 hours.

Safety instructions:

Operators should wear gloves and protectiongoggle while monitoring refrigerant filling machine. Do not smoke near thedevice while the refrigerant filling machine is working. Never use refrigerantfilling machine around a heat supply, fire or sparkles. Do not expose thedevice under the sun or to rainfalls. Please use it in the environment withgood ventilation.
