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.

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

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.
When the charge cycle gets close to the weight

if a material is a hazardous waste at
the time of disposal. Ensure you are
