Congratulations on the purchase of the AC-200-dual
Refrigerant Processor
This is a very good investment you have made for your workshop. This system will help your technicians in achieving their
best capability in diagnosing and rectifying air-conditioning issues, thus increasing productivity and profitability for your
business. This system can be customized to suit each individual workshop needs. Our company would like to work with you
as partners in your business to help you achieve maximum return on your investment, so please do not hesitate to contact us
or our distributors, if we can be of any further assistance in relation to this equipment use and maintenance, or any
air-conditioning related issues. We are always here to help you in achieving higher productivity.
AC-200-dual is an ideal option for workshops that have requirements of handling 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. The machine is equipped with 2 refrigerant tanks,
which saves the operators' time of replacing tanks.
The unique design has facilitated quick load cell unlock, easy and economic maintenance (even though DIY maintenance is
facilitated by our machine design, it is still highly recommended to leave maintenance job to specialized technicians.), self
troubleshooting and convenient USB upgrade etc..
General safety
The storage cylinder in this unit contains liquid refrigerant. Overfilling of the cylinder can cause violent explosion. Do
not disable the overfill safety feature. Always keep the cylinder on the load cell platform whenever operating the
machine.
The operator must carefully read the instruction manual before any operation is performed. Incorrect operations could
cause serious consequences, such as, improper A/C service, damage to automotive A/C system or damage to
equipment.
Only use cylinders which are recommended by the manufacturer and supplied with this equipment.
Avoid inhalation of refrigerant or oil vapor/mist, read material safety instructions on refrigerant and oil package.
Switch off and disconnect power cable from main supply before removing any cover or servicing the equipment, to
avoid electric shock which can be very dangerous or fatal.
Never use compressed air for leak testing the unit or vehicle A/C system!
Wear safety goggles and gloves, to protect eyes and skin from contact with refrigerant. Coming in contact with liquid
refrigerant can cause frostbite and blindness. If accidental contact is made with liquid refrigerant, wash effected area
with plenty of fresh water and contact a doctor.
Avoid using extension power cable with copper core diameter less than 1.5mm2.
Keep gasoline or other flammable substances away from the equipment.
Always operate unit in a well-ventilated area and away from artificial heat

OPERATION PREPARATIONS
Unlock load cells.
Remove the two lock bolts, to release load cells of the two tanks, and to make them ready to work.
Warning:
1. Failure to remove the load cell lock bolts may cause wrong refrigerant processing amount.
2. When you need transport the machine, please screw those bolts on.
Fill equipment with refrigerant (New equipment is empty, you need to fill the equipment
with refrigerant and refrigeration oil)
Through tank fittings, connect either HP or LP hose with external refrigerant R134a or
HFO-1234yf, and turn on the machine, select “Tank fill” function, set tank fill amount to fill
R134a or HFO-1234yf tank with refrigerant.
It is recommended to maintain refrigerant level of both tanks at 4-6kg.

Non-condensable purge
It is recommended to purge the air in equipment tanks every day before turning on the machine.
At left and right sides of machine, non-condensable purge manual valves and
pressure-temperature chart can be found. Turn the valve to purge the non-condensables, strictly
abiding by the pressure-temperature chart sticker.
Select refrigerant
Each time the machine is turned on, it reminds to select refrigerant type. If the refrigerant type
selected is different from the refrigerant handled at previous operation, the machine automatically
recovers refrigerant inside machine pipelines, and makes extremely deep internal evacuation, and
then shifts to the interface of the selected refrigerant. This process may take 5 minutes or more.
Notes:
1. Be sure you select same refrigerant type as what the vehicle contains, or serious
contamination in equipment tanks will be caused.
2. Anytime you desire to shift from the refrigerant which machine currently handles to
another, turn the machine off and turn it on again, and then select refrigerant type.

Equipment Connection (For recovery/vacuum/oil injection/charge/Auto. Mode)
Warning: Except the situations clearly stated in the manual, during all equipment operations, please maintain
the vehicle engine and A/C off, otherwise unexpected damages may be caused.

Recovery
Empty used oil vessel before the recovery function is started.
Select “Recovery” function icon and press ENTER to start the process.
The recovery process recovers the refrigerant from vehicle A/C system, until vacuum degree is
achieved in the vehicle A/C system. Moisture, oil and foreign particles are separated from the
refrigerant before it is stored 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 completed. If a pressure increase is detected recovery should be
processed again.
Vacuum
Select “Vacuum” icon and press ENTER to start the process.
The Vacuum process evacuates system, and makes system ready for oil injection and refrigerant
charge. Although it is up to users to determine vacuum time, a longer vacuum process is
recommended.
