Safety PrecautionS
WARNING : TO PREVENT PERSONAL INJURY AND / OR EQUIPMENT DAMAGE,
ALLOW ONLY QUALIFIED PERSONNEL TO OPERATE THIS 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 storage vessels, because
overfilling 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 personal injury. Wear protective equipment, including safety goggles and protective gloves.
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 systen, 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.
TO REDUCE THE RISK OF FIRE, USE THE SHORTEST POSSIBLE EXTENSION CORD WITH A
MINIMUM SIZE OF 14 AWG. Using an undersized extension cord may result in electrical equipment
failure.
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 OR VEHICLE AIR
CONDITIONING 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.
DO NOT MIX REFRIGERANT TYPES THROUGH A SYSTEM OR IN THE SAME CONTAINER.
Mixing of refrigerants causes severe damage to the unit and the system being serviced.
HIGH VOLTAGE ELECTRICITY INSIDE THE UNIT HAS A RISK OF ELECTRICAL SHOCK. Exposure
may cause personal injury. Disconnect power before servicing the unit.
