● Use our original recovery cylinders.
● Use cylinders on which the type of refrigerant to be recovered is mentioned.
● Empty cylinders should be evacuated before use.
● How to evacuate air (Vacuum pump is optional)
① Connect the suction port of the vacuum pump
to the vapor port of the cylinder with a hose.
② Switch on the vacuum pump.
③ Close the liquid port of the cylinder and open
the vapor port.
④ Close the vapor port of the cylinder when
the vacuum reaches -72cmHg/-28inHg to
-76cmHg/-30inHg.
⑤ Switch off the vacuum pump.
⑥ Disconnect the hose between the vacuum pump
and the cylinder.

● How to shorten the recovery time
① After liquid recovery is completed, recover
from both the liquid and the vapor ports.
② Remove the valve cores of the service ports
of the system if they have.
③ Remove the core depressors of the charging
hoses.
④ Use large size 3/8” hoses.
⑤ Replace the gaskets of the hoses if they are
deformed.
⑥ Recover refrigerant while operating the
crank case heater of the system.
⑦ Heat up the accumulator by a heat gun or
give it vibration if it is frozen.
⑧ Recover from multiple systems in one time.
● How to avoid rise in temperature and
pressure in the cylinder
① Put the recovery machine in a well-
ventilated shady area.
② Do not put the recovery machine and the
cylinder directly on the floor but put them
away from the floor.
③ Cool down the cylinder with wet cloths.
④ Use Cooling Unit (optional accessory) (See
page 19).
⑤ Reduce the suction pressure of the recovery
machine (See page 19).
⑥ Replace the cylinder with an empty one.
⑦ Cool down the cylinder with the sub-cooling
procedure (See page 19).
⑧ Use a 120L cylinder.
4）Helpful Information
HOW TO USE
◆ The cylinder is designed according to the specifications of the recovery machine.
The cylinder may be overfilled and exploded if the appropriate cylinder is not used.
◆ Brand-new cylinders have nitrogen inside.
Evacuation should be done after discharging nitrogen by opening the vapor valve.
◆ Do not evacuate air from cylinders which contain refrigerant.
The refrigerant will be discharged to the air and the vacuum pump oil will blow out.
◆ Do not evacuate air from cylinders by using the recovery machine.
The compressor may be damaged if it is run for a long time under vacuum.
