WARNINGS

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

– Si el operador no puede leer las instrucciones, las instrucciones de operación y las

precauciones de seguridad deberán leerse y comentarse en el idioma nativo del operador.

– Si l’utilisateur ne peut lire les instructions, les instructions et les consignes de sécurité doivent

lui être expliquées dans sa langue maternelle.

PRESSURIZED TANK CONTAINS LIQUID REFRIGERANT. Do not recover or charge refrigerants into non-refillable containers; use only authorized refillable containers.

ALL HOSES MAY CONTAIN LIQUID REFRIGERANT UNDER PRESSURE. Contact with refrigerant may cause personal injury. Wear protective equipment, including safety goggles. Disconnect hoses with extreme caution.

DO NOT BREATHE REFRIGERANT AND LUBRICANT VAPOR OR MIST. Exposure may cause personal injury, especially to the eyes, nose, throat, and lungs. 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.

AVOID USING AN EXTENSION CORD. An extension cord may overheat and cause fire. 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 flammable substances.

DO NOT USE COMPRESSED AIR TO PRESSURE TEST OR LEAK TEST THE UNIT OR VEHICLE AIR CONDITIONING SYSTEM. Some mixtures of air and refrigerant are combustible at

elevated pressures. These mixtures are potentially dangerous and may result in fire or explosion causing personal injury or property damage.

USE THIS UNIT WITH ONLY R-134a REFRIGERANT. The unit is for recovering, recycling, and recharging 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 opening the back door or servicing the unit.
