Page 3: Warning For Safety
ECOcycle Aurora Ⅱ WARNING FOR SAFETY ● General warnings in operating this machine are mentioned in this section. ● While specific details are mentioned in each particular clause. WARNING ◆ When performing recovery, choose location that has good ventilation. Leakage of gas without sufficient ventilation may cause lack of oxygen cause suffocation. ◆ Can not recover flammable gas (Hydrocarbon or this kind of hydrocarbon material) When mix except refrigerants [Ammonia, hydrocarbon （propane, isobutene,）etc] to the machine, it may cause explosion. ◆ Burning Freon creates a deadly poisonous Carbon Oxy-Chloride and inhaling of this gas is very dangerous. There should be absolutely no flammable material near the working area and must operate under good ventilation. - Page 4 ECOcycle Aurora Ⅱ WARNING ◆ Check electric power plug regularly to make sure there is no problem. Always have the plug inserted firmly. When the plug has dirt or oil, and the connection is incomplete, it may cause electric shock or fire. ◆ Do not have the electric cord connected with other electric devices or branched with other cords. It may cause fire. ◆ Do not pull the electric power source cord and remove from the outlet. It may cause fire or injury. ◆ The power source should be AC220-240V 10A or use a generator whose capacity is 3KVA or more.
- Page 5 ECOcycle Aurora Ⅱ CAUTION ◆ Install a filter at the suction port. Otherwise the compressor may be damaged. ◆ An extension cord used should be a three-core cabtyre cable with a length of 20m or less when its wire diameter is 2.0mm or with a length of 30m or less when its wire diameter is 3.5mm An unsuitable extension cord (too thin or too long) may lead to starting failure or fire. Or electrical components such as capacitor, relay and so on may be damaged. If the cord used is a two-core cord without a ground wire, you may get electric shock. ◆ Do not recover refrigerant which contains sealant. Sealant may clog the valves or the check valves. ◆ Do not let visitors touch the machine. ◆ Do not use the machine when the result is unpredictable. ◆ Do not use the machine for purposes other than the original intent. This machine is designed to recover the specified refrigerants. ◆ Do not operate under an excessive heavy load to the machine. Operating under an excessive load can not only cause damage to the machine but also causes an accident. ◆ Do not use the machine on a vibrating floor or on a sloping place. The machine or the cylinder may fall down and lead to accident. ◆ The operating platform and the work area must be kept neat and clean. at all time and have enough lighting. Poor working environment causes accident. ◆ Do not operate the machine if the operator is under fatigue condition or influenced by alcoholic drink or medicines. ◆ When the Recovery Machine is not in use, storage at dry space and out of reach by children.
- Page 6 ECOcycle Aurora Ⅱ CAUTION ◆ When the Recovery Machine is dropped or hit, inspect immediately for damage, crack, dent, etc. Recovery under damaged, cracked and dented condition may cause injury. ◆ Check every day if there is deformed or corroded area. ◆ If abnormal condition (strange smell, vibration, strange noise) is noticed, stop the unit and refer to the Page22 “ BEFORE REQUESTING REPAIR OR SERVICES” in the manual. ◆ Request for repair or service instead of disassembling for repair, contact the store where the machine was purchased.

ECOcycle Aurora Ⅱ RECOVERY CYLINDER Risk of overfilling ● Refrigerant is a high pressure gas and mistakes in use or handling will lead to a serious accident. 1）Relation between the temperature and the pressure of refrigerant in a cylinder The pressure of the refrigerant varies depending on the ambient Saturation pressure and saturation temperature of each type of refrigerant temperature when the refrigerant is filled in a cylinder. Temperature Some liquid refrigerant R502 Pressure rises rises evaporates R134a At this time, lowering of the liquid level by evaporation and rising R407C of the liquid level by specific volume increase occur at the same R410A time and balance. R404A R507A Temperature Some vapor refrigerant Pressure drops drops liquefies At this time, rising of the liquid level by liquefaction and lowering of the liquid level by specific volume decrease occur at the same time and balance. The right graph shows the relation between the pressure (saturation pressure) and the temperature (saturation temperature) for each kind of refrigerant. -
