SAFETY DEFINITIONS: Follow all WARNING, CAUTION, and NOTE messages in this manual. These messages are dened as

follows: WARNING means you may risk serious personal injury or death; CAUTION means you may risk personal injury, property

damage, or unit damage; and NOTEs and OPERATING TIPS provide clarity and helpful information. These safety messages cover

situations ROBINAIR is aware of. ROBINAIR cannot know, evaluate, and advise you as to all possible hazards. You must verify that

conditions and procedures do not jeopardize your personal safety.

DISCLAIMER: Information, illustrations, and specications contained in this manual are based on the latest information available

at the time of publication. The right is reserved to make changes at any time without obligation to notify any person or organization

of such revisions or changes. Further, ROBINAIR shall not be liable for errors contained herein or for incidental or consequential

damages (including lost prots) in connection with the furnishing, performance, or use of this material. If necessary, obtain additional

health and safety information from the appropriate government agencies and the vehicle, refrigerant, and lubricant manufacturers.

ALLOW ONLY QUALIFIED PERSONNEL TO OPERATE THE UNIT. Before operating the unit, read and follow

the instructions and warnings in this manual. The operator must be familiar with air conditioning and refrigeration

systems, refrigerants, and the dangers of pressurized components. If the operator cannot read this manual,

operating instructions and safety precautions must be read and discussed in the operator’s native language.

PRESSURIZED TANK CONTAINS LIQUID REFRIGERANT. Do not overll the internal storage vessel, because

overlling may cause explosion and personal injury or death. Do not recover refrigerants into nonrellable

containers; use only federally authorized rellable containers (DOT spec. 4BW or 4BA).

HOSES MAY CONTAIN LIQUID REFRIGERANT UNDER PRESSURE. Contact with refrigerant may cause per-

sonal injury. Wear protective equipment, including safety goggles. Disconnect hoses using extreme caution.

AVOID BREATHING A/C REFRIGERANT AND LUBRICANT VAPOR OR MIST. Exposure may irritate eyes,

nose, and throat. To remove refrigerant from the A/C system, use only equipment certied for the type of

refrigerant being removed. Use the unit in locations with mechanical ventilation that provides at least four air

changes per hour. If accidental system discharge occurs, ventilate the work area before resuming service.

DO NOT USE AN EXTENSION CORD. An extension cord may overheat and cause re. If you must use an

extension cord, use the shortest possible cord with a minimum size of 14 AWG.

TO REDUCE THE RISK OF FIRE, do not use the unit in the vicinity of spilled or open containers of gasoline

or other ammable substances.

CAUTION—DO NOT PRESSURE TEST OR LEAK TEST EQUIPMENT AND / OR VEHICLE AIR CONDI-

TIONING SYSTEMS WITH COMPRESSED AIR. Some mixtures of air and refrigerant have been shown to be

combustible at elevated pressures. These mixtures, if ignited, may cause injury or property damage.

TO PREVENT CROSS-CONTAMINATION, USE THIS UNIT WITH R-134a REFRIGERANT ONLY. The unit is

designed to recover, recycle, and recharge only R-134a refrigerant. Do not attempt to adapt the unit for another

refrigerant. Do not mix refrigerant types through a system or in the same container; mixing of refrigerants will

cause severe damage to the unit and the vehicle air conditioning system.

HIGH VOLTAGE ELECTRICITY INSIDE THE UNIT HAS A RISK OF ELECTRICAL SHOCK. Exposure may

cause personal injury. Disconnect the power before servicing the unit.

Additional health and safety information may be obtained from the refrigerant and lubricant manufacturers.

button is pressed. Verify the high- and low-side

hoses are connected and coupler valves are

open. Press STOP / NO to exit.

• If 100 lbs. (45 kg) or more of refrigerant has

been recovered since the last lter-drier change,

the display reads

FILTERWEIGHTXXXLB(XXKG)



To meet SAE J-2788 requirements, it is

mandatory to replace the lter-drier after

150 lbs. (68 kg) of refrigerant has been

ltered.The unit gives a warning to replace

the lter when lter weight reaches 100 lbs.;

when lter weight reaches 150 lbs., the unit

locks out and ceases to operate.Refer to

instructions outlined in the Maintenance section

under Replace the Filter-Drier.

Note:

• During a charge cycle, if the unit fails to transfer

refrigerant due to low tank pressure, the charge

process is automatically interrupted and the unit

operates in a mode to build tank pressure. Once

tank pressure is sufcient, the unit automatically

completes the charge.

pump is pressurized during normal operation.

Review the laws in your jurisdiction

to determine the correct disposal

responsibility of the user to determine

if a material is a hazardous waste at

the time of disposal. Ensure you are
