Safety warning
Read this manual carefully and understand all the procedures outlines in this manual before operating the
unit. Failure to follow these procedures could result in personal injury or property damage.
Allow only qualified personnel to operate this unit. The operator must have basic knowledge of air
conditioning and refrigeration systems, including potential hazards associated with the handling of refrigerants
and systems under high pressure.
Always wear safety goggles and appropriate protective clothing. Avoid contact of liquid refrigerant with the
eyes and prolonged skin exposure.
Pressurized tank contains liquid refrigerant.
Never fill the refrigerant tank to more than 80% of its maximum capacity.
Hoses may contain refrigerant under pressure.
Make sure to use a properly grounded AC outlet.
Do not operate the unit with a damaged cord or plug. Extension cords should not be used unless absolutely
necessary.
Disconnect unit from power supply before removing any protective cover.
Do not expose the unit to wet environment.
Only use the correct refrigerants.
Avoid breathing in refrigerant vapors. Use only in well ventilated areas.
The unit must be transported in a vertical position.
The refrigerant scale must be fixed in place before transport.

Safety warning
UYARILAR: Kişisel yaralanmaları önlemek için,
ALLOW ONLY QUALIFIED PERSONNEL TO OPERATE THE MACHINE. Before operating the
machine, 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 overfill the internal storage vessel
(ISV), because overfilling may cause explosion resulting in personal injury or death. Do not
recover refrigerants into nonrefillable containers; use only type-approved refillable containers
that have pressure relief valves.
HOSES MAY CONTAIN LIQUID REFRIGERANT UNDER PRESSURE. Contact with refrigerant may
cause personal injury, including blindness and frozen skin. Wear protective equipment, including
goggles and gloves. Disconnect hoses using extreme caution. Ensure the phase has been
completed before disconnecting the machine to prevent the release of refrigeration to the
atmosphere.

Safety warning
DO NOT BREATHE REFRIGERANT AND LUBRICANT VAPOR OR MIST. Refrigerant reduces the
oxygen available for breathing, resulting in drowsiness and dizziness. Exposure to high
concentrations of refrigerant causes asphyxiation, injury to the eyes, nose, throat, and lungs, and
can affect the central nervous system. Use the machine in locations with mechanical ventilation
that provides at least one air change per hour. If accidental system discharge occurs, ventilate
the work area before resuming service.
DO NOT DISPERSE THE REFRIGERANT INTO THE ENVIRONMENT. Such a precaution is necessary
to prevent the possible presence of refrigerant in the working environment.
TO REDUCE THE RISK OF FIRE:
Do not use 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.
Do not use the machine in the vicinity of spilled or open containers of gasoline or other
flammable substances.
Do not use the machine in the vicinity of flames and hot surfaces. Refrigerant decomposes at
high temperatures, freeing toxic substances to the environment which are noxious to the
user.
Do not use the machine in environments containing explosive gases or vapors.

Safety warning
DO NOT USE COMPRESSED AIR TO PRESSURE TEST OR LEAK TEST THE MACHINE OR VEHICLE
AIR CONDITIONING SYSTEM. Mixtures of air and refrigerant can be combustible at elevated
pressures. These mixtures are potentially dangerous and may result in fire or explosion causing
personal injury and / or property damage..
HIGH VOLTAGE ELECTRICITY INSIDE THE MACHINE HAS A RISK OF ELECTRICAL SHOCK. Exposure
may cause personal injury. Disconnect the power before servicing the machine.
DO NOT MODIFY THE PRESSURE RELIEF VALVE OR CHANGE THE CONTROL SYSTEM SETTINGS.
Using the machine in a manner for which it was not designed will compromise the machine and
nullify the protections provided.
